I need to know if there is something like SignalR but for Winforms, some nuggets or library for paid, someone who can guide me please.
The beginning of my problem is that I have the need to obtain data automatically when the table is updated.
Thanks.
I have an external singlethreaded program that needs to be run multiple hundred times with different parameters. To make it faster I want to run it once for each core at the same time. To do that I used Parallel.ForEach running on a list with the different parameters to pass to the external program:
var parallelOptions = new ParallelOptions {
MaxDegreeOfParallelism = Environment.ProcessorCount // 8 for me
};
Parallel.ForEach(ListWithAllTheParams, parallelOptions, DoTheStuff);
...
private void DoTheStuff(ParamType parameter, ParallelLoopState parallelLoopState, long index)
{
// prepare process parameters etc.
theProcess.Start();
theProcess.WaitForExit();
}
Pretty straightforward and works nicely... until the last ~10 items - they don't get parallelized for some reason and just run one after another. I've confirmed this by looking at the cpu usage and the running programs in the Task Manager.
This does not happen when I populate the parameter list with only a few (say, 10) items.
Can somebody explain this behavior to me? Any hints or tips appreciated!
Consider the following code:
Dim doubleResult = (21 / 88) * 11
Dim decimalResult = Decimal.Divide(21, 88) * 11
The doubleResult is 2.625, as it should.
The decimalResult is 2.6249999999999996, so when rounding this to two decimal places will give an incorrect result.
When I change the assignment to:
Dim decimalResult = Decimal.Divide(21 * 11, 88)
The result is 2.625!
We adopted the decimal type in our application hoping that it would give us increased accuracy. However, it seems that the decimal type just gives slightly incorrect results on other calculations than the double type does, due to the the fact that it is ten based, rather than two based.
So, how do we have to deal with this idiosyncrasies to avoid rounding errors as above?
I have a form that displays a set of graphics using a Paint event on a Panel that is docked inside a particular TabPage of a TabControl.
When the user switches to a different TabPage and then decides to go back to the TabPage where the graphics were originally displayed, those graphics are invalidated by default so the Panel appears blank.
I would like those graphics to stay unaltered and totally independent from the user's action when switching between different TabPages.
Since the graphics are complex and take some time to be drawn by the computer, I don't want to repaint the graphics each time by calling the Paint event repeatedly. Instead, I only need to avoid the default invalidation of the graphics.
I have read this other question which may be helpful to solve my problem but it goes beyond my knowledge.

I have made all the usual steps for deploy on iss. The IUSRS -NetworkService has full rights on the web project
There is a mobile game on which I am working. It has various difficulty sections and each section has numerous levels, 250 levels in each section precisely.
Now, I need a suitable control which can display all the levels and by tapping on a certain level's button/icon, the user is able to move on and play that level.
I tried using a simple ScrollViewer, but that is way too much scrolling for the user even if I display 10 levels in a single row.
So, is there any inbuilt/existing control in WP that I can use to solve my problem?
P.S. Do remember, there are more than 250 levels that need to be displayed.
Many thanks in advance. Cheers!
Does anybody know how can I insert the Text Form Field to the MS Office Word 2003 Document (.doc)? And I also want to set the read-only property fo this field. How can I do this with C#?
What do you think is the best way of updating an existing SQL Server (we are using SQL Server 2014, but could update to 2016) database schema (incl its data) with zero downtime of the overall system, i.e. applications using the database?
The business requirements is to have a zero downtime of all the applications and services using the database. We could say we only do backwards and forward compatible database schema changes, e.g. adding columns, but not removing existing columns.
Of course the business would like to have a backup before we do the database change, in case something goes really wrong and we need to rollback.
The system is transactions heavy, meaning potentially thousands of transactions per second.
The applications are .net applications, where most of them run in an IIS execution container at the moment (maybe we switch to some other form like self-hosted service etc.) and exopsing their functionality through Web Services.
What would be your approach?
I would like to write a unit test to
1) go through a list of 1 million unique random generated strings.
2) Ensure that each numer is 100% unique and there are no duplicates.
What is the best way to check and compare that there are no duplicates.
I have a List<List<int>> set of data, with string representation like this (to give the idea!):
{{1,3},{-1,-3},{2,5},{-2,-5},{-3,4},{-5,4},{3,5,-4},{6,-8},{7,-8},{-6,-7,8},{7,9},{-7,-9},{3,8,-10},{-3,-8,-10},{-3,8,10},{3,-8,10},{4,9,-11},{-4,-9,-11},{-4,9,11},{4,-9,11},{10,11},{-1,6},{1,-6},{-2,7},{2,-7}}
I want to check if ,in all present numbers, exist a number or set of numbers which only are in positive form. I mean if in the whole data, there is 3 and -3 I should return false, otherwise I have to add 3 as a number which only is present as positive 3, in to another list. (Same thing for only negated number)
Here is how I am trying to do it:
First, generate a unique set of numbers and remove negatives:
private void GenerateCurrentExistingVariables()
{
_uid = new List<int>();
var all = _cnf.Data.SelectMany(list => list).ToList();
_uid = all.Distinct().ToList(); //make list unique
_uid.Sort(); //sort numbers
_uid.Reverse(); //reverse so highest numbers would evalaute first!
_uid = _uid.Where(i => i >= 0).ToList(); //remove negative numbers
}
Then I do something like this:
in a method, I call the code below:
for (var i = 0; i < _uid.Count; i++)
{
if (ExistOnlyInNegatedForm(_uid[i]))
{
onlyNegatedList.Add(_uid[i]);
}
//perhaps continue
if (ExistOnlyInPositiveForm(_uid[i]))
{
onlyPositiveList.Add(_uid[i]);
}
}
Which in turns calls the methods below:
private bool ExistOnlyInPositiveForm(int id)
{
for (var i = 0; i < _cnf.Data.Count; i++)
{
for (var j = 0; j < _cnf.Data[i].Count; j++)
{
if (_cnf.Data[i][j] == id)
{
return false;
}
}
}
return true;
}
private bool ExistOnlyInNegatedForm(int id)
{
var toCheck = -id;
for (var i = 0; i < _cnf.Data.Count; i++)
{
for (var j = 0; j < _cnf.Data[i].Count; j++)
{
if (_cnf.Data[i][j] == -toCheck)
{
return false;
}
}
}
return true;
}
This is too much code for this simple task and I feel that this is getting slower and slower when data grows larger...please let me know how can I improve this. Also I would like this to be done using LINQ at least for the sake of less lines of code!
I would love to see a C++ solution as well, so I am tagging c++ in my question (not doing language spam!)
In my directory on the hard disk i have many images: screenshot000001.bmp , screenshot000002.bmp....screenshot001200.bmp
I want to do two things:
For testing using the CMD and to compress and convert the images to mp4 video file.
In my program in real time while my program take the screenshots and save them to the hard disk to compress them and build the mp4 video file in real time.
For the first part i tried to type in cmd :
ffmpeg -f image2 -i screenshot%d.bmp -vcodec libx264 -b 800k video.avi
But what i got is two errors:
[image2 @ 0000000004766380] Could find no file with path 'screenshot%d.bmp' and index in the range 0-4 screenshot%d.bmp: No such file or directory
I copied the ffmpeg.exe to the directory where the images are in. E:\screenshots
For the second part this how i'm taking the screenshots in real time:
A button click event that start a timer:
private void button1_Click(object sender, EventArgs e)
{
timer1.Start();
}
Then in the tick event:
ScreenShot shot = new ScreenShot();
public static int counter = 0;
private void timer1_Tick(object sender, EventArgs e)
{
counter++;
shot.GetScreenShot(@"e:\screenshots\", "screenshot");
if (counter == 1200)
{
timer1.Stop();
}
}
This line shot.GetScreenShot(@"e:\screenshots\", "screenshot"); save the screenshots to the hard disk. Here after each screenshot save i want to compress and build the mp4 video file in real time.
I am creating a intranet application to my company which contains different plugins developed by us or commonly used plugins. It is a responsive design. Now I have a new requirement to show the widget demos in different mobile devices like iphone, android etc.

I have a solution where all projects are targeting .NET v4.5.1.
TeamCity (v9.0.4) previously has built the solution just fine.
Added an Asp.Net web application (MVC + WebAPI) to the solution, still targeted at .NET 4.5.1.
It Works on My Machinetm, but TeamCity now fails the build with the following MSBuild error:
[src\app\Web\Web.csproj] C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\Web\Microsoft.Web.Publishing.targets(186, 67): error MSB4025: The project file could not be loaded. There is an unclosed literal string. Line 186, position 67.
Those might be the line numbers in the targets file that threw the error, because in my file all I see is a </ProjectReference> (which corresponds correctly to two project references that are there.
Any idea what could be causing this?

Are there any code formatter for vb.net that can automate code formatting? like perl's perltidy.

Thank you!
I have the following class:
public class Order

public string Code { get; set; }
}
And I have built dynamically an Expression, which looks like this:
and I'm building an extension method which looks like:
I have a list of orders which, List<Order> of the expression type and when I apply the filter like this:
var buildExpressionFilter = dynamically constructed Expression here
var orders = GetOrders();
var result = orders.Where(buildExpressionFilter).ToList();
I get the following error:
Is obviously that buildExpressionFilter is not properly constructed but I cannot figure out what is the issue.
Does anyone have an idea on how to fix this issue? What may be wrong with my buildExpressionFilter?
I dont have any experience with VST. Just started researching.
I need to call the member function VSTPluginMain from my VST dll to do some custom audio processing in my Unity 5 project. For a VST host, I added VST.NET 1.0 CLR2 X64 Release dlls in my project. I've read Unity supports only Common Language Runtime 2.
The documentation for VST.net is not working (a blank .chm file and the online version is incomplete). I wasn't able to find any useful samples in the VST.net project templates. Also, does Unity support VST? (the Unity forums are silent about this matter)
Any help is greatly appreciated.
Thank you
Is it possible to add an ASP.NET 5 Web Application as a reference to a traditional .NET 4.5 project (Windows Service or Console App) and start it in-process?
Ideally within one solution, so that ASP.NET application and host service can share references to other projects in the same solution.
Tried so far:
dnu publish produces packages, but attempting to add them produces following error: Install-Package : Could not install package 'WebApplication1 1.0.0'. You are trying to install this package into a project that targets '.NETFramework, Version=v4.5', but the package does not contain any assembly references or content files that are compatible with that framework. When changing framework dnx451 to net451, Web Application doesn't compile because of missing ASP references.
dnu build produces binaries, but how to run the application? (where to get IApplicationBuilder and IHostingEnvironment instances?)
I am new to C# and I want to create a little Autorun Manager in a Console Application. To do that I want to read from the console a keyword like "Steam" and my programm should search on "C:\" and in all subdirectories for a folder called like my keyword but as I say I have no Idea how I can search in all subdirectories.
Thats a little code sample with steam how I would write in registry
//filePath would be the Path of the .EXE file that was found
string filePath = "\"C:\\Programme\\Steam\\Steam.exe\"";
string autostartPath = @"Software\Microsoft\Windows\CurrentVersion\Run\";
RegistryKey autostart = Registry.CurrentUser.OpenSubKey(autostartPath, true);
autostart.SetValue("Steam", filePath);
If someone know how to search in all subdirectories and find the correct .exe file.
I would be really grateful for a code sample.
Thanks in advance

I am reading an image from file that contains transparency area in the center (frame image type).
Image myFrame = Image.FromFile("d:\mypngfile.png");
After i call image resize custome function:
myFrame = resizeImage(myFrame, new Size(otherbmp.Width, otherbmp.Height));
The problem is that after reszing the image it seems transparency is removed.
resize function:
public Image resizeImage(Image imgToResize, Size size)
{
int sourceWidth = imgToResize.Width;
int sourceHeight = imgToResize.Height;
float nPercent = 0;
float nPercentW = 0;
float nPercentH = 0;
nPercentW = ((float)size.Width / (float)sourceWidth);
nPercentH = ((float)size.Height / (float)sourceHeight);
if (nPercentH < nPercentW)
nPercent = nPercentH;
else
nPercent = nPercentW;
int destWidth = (int)(sourceWidth * nPercent);
int destHeight = (int)(sourceHeight * nPercent);
Bitmap b = new Bitmap(destWidth, destHeight,PixelFormat.Format32bppArgb);
b.MakeTransparent();
Graphics g = Graphics.FromImage((Image)b);

g.PixelOffsetMode = PixelOffsetMode.HighQuality;
g.DrawImage(imgToResize, 0, 0, destWidth, destHeight);
g.Dispose();
return (Image)b;
}
After i am checking the alpha pixels which doesn't work after resize (it does work before resizing and returns a value). It always return 0!

var hy = bmp.Height/ 2;
while (bmp.GetPixel(0, hy).A == 255 && sz.Width < hx)

How do I submit a form and loads the results from the request in a new view.
I have the following routes
routes.MapRoute(
name: "Default",
url: "{controller}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "GetResults",
url: "{gueryString}",
defaults: new { controller = "Result", action = "ShowResults", gueryString = "" }
);
I have a index view with includes a partial view of my form I want to submit.
@Html.Partial("../Result/SearchForm")
The form itself is
@using (Html.BeginForm("ShowResults", "Result", method: FormMethod.Post))
{
<form role="form">
<div class="input-group input-group-lg">
@Html.TextBoxFor(m => m.searchString, new { @class = "form-control" })
<a href="javascript:$('form').submit();" class="input-group-addon">
<i class="fa fa-search"></i>
</a>
</div>
</form>
}
The new action itself in class ResultController
public ActionResult ShowResults(SearchSubmitModel model)
{
RequestExternalComparisonData.ValidateSearchString(model);
ViewBag.GameComparisonList = RequestExternalComparisonData.DoSearch(model.searchString);
return View();
}
The problem is the default index action is always ran on the form submit unless I completely remove the default route, but I need to initially load the index with my form. How do I trigger my new action on the form submit?
I am using a generic handler to download csv/excel files. It was working fine until yesterday. Today suddenly it stopped working on deployment on IIS 7.5 (though he same code works well in visual studio debugging mode). Here is my code:

var $mod = $("#masterModal");
$mod.modal('show');
//window.location = "Handlers/DownloadData.ashx?rtp=" + combobox.val();
window.location.href = $(btn).attr("navurl") + "?rtp=" + combobox.val();

All above code works well in debugging mode and was working well in deployment mode as well. Don't know what has changed that it suddenly stopped working and I am unable to find out any reasons :(
Behaviour on deployment: Instead of staying on same page and downloading file it navigates to Handler and a blank screen is displayed. No file is downloaded.
Behaviour in debuuging mode OR when run using vs2012 express: It stays on same page and downloads the file as expected.
Somebody please help me on this.
I want to create method in my WCF service that will return json.

What am I doing wrong?
I saw similar questions but none of them help me.
It is understood, need to get license for publishing and distributing Windows Store Apps. But it is not clear how much it costs and procedure. Please clarify the following:
My app has a requirement to not to publish the app in store, but to distribute it internally. Sideloading seems to be option.
But I'm confused what are costs for doing so? For sideloading, it is said we need to buy keys. how much it is?
Do I have to pay for each device that uses this sideloaded app? Is there any other costs or related software/license requirements with it? this blog says there is per month subscription fee for devices.
Is there any other requirement other than sideloading keys like OS version or domain? Should the devices have particular version of OS or anything (such Windows 8.1 premium is must)? this says it devices should be in domain?
If submitted to windows store, is there a way to hide from public view and allow the app to downloaded for intended users who are using Windows 8.1? Hide this app in the store will not work as it has a limitation of not able to use with Windows 8.1.
Technet says app can be sideloaded to all users as an image. But in that option also users have run the powershell and type the command to install the app. Is there a way to make enduser's life easier by making the installation simple as double click?
Thanks in Advance
How to create a ADO.NET adaptor for SQLite (i.e. generate my own DLLs from SQLite C source code, instead of using other existing DLLs or NuGet to install SQLite.) I want to do it as a learning experience but find no instruction on google.
I will use C#.NET in WPF VS2015 on x64. Do I compile the source in VC++ as a DLL and then reference to it in a new solution ? Will the DLL be x86 and x64 compatible or do I generate two separate DLLs?
I'm trying to compile a relatively big legacy c++ project in visual-studio-2013 using /clr flag. The project generates a dll.
I get the following run-time exception:
Type '<Module>' from assembly ... contains more methods than the current implementation allows
I must add that this happens in Debug configuration only (Release - works). Also, the project heavily uses templates and macros, which (I suppose) contribute to the large amount of generated methods...
There is little to no documentation regarding this problem. What I know from searching the net (don't know if it's accurate) is:
There is a limit of ~65K methods in a clr dll. All methods of all native classes go into some special <Module>, so it poses a global limit.
One suggestion was to split the project, but that's not very trivial, due to inter-class-dependencies. I suppose this is doable...
Any help would be appreciated.

I have VB.NET solution targeting .NET 4.0 Client Profile that includes add-ins for Excel and PowerPoint. There is a separate assembly for each, and a third assembly with code that is common to both. So, the common assembly is a dependency of the other two.
Sometimes, but not predictably or reliably, when code in the common assembly opens a MessageBox, it is dismissed automatically without user input. It seems as if the calling assembly (i.e. the Excel add-in) has seized back control of the UI from the common assembly (maybe something to do with threading?), or the calling assembly code just continues executing while the MessageBox is shown.
I have observed this behavior in various and completely separate parts of my solution, and cannot figure out what the problem is. Again, this does not happen all the time, and I cannot reproduce the condition reliably. I am testing this on Windows 8.1 in Office 2013.
Unfortunately, there really isn't any relevant code to post, except:
MessageBox.Show(...)
I am hoping someone can provide some insight into what may be happening here, and provide a fix.
EDIT
After incorporating Hans' suggestion below, my code is now:
MessageBox.Show(New WindowWrapper(handle), [Message], [Caption], MessageBoxButtons.OK, [Icon])
where handle [Integer] = Excel.Application.Hwnd and:
Public Class WindowWrapper
Implements IWin32Window
Private hwnd As IntPtr
Public Sub New(handle As IntPtr)
hwnd = handle
End Sub
Public Sub New(handle As Integer)
hwnd = New IntPtr(handle)
End Sub
Public ReadOnly Property Handle As IntPtr Implements IWin32Window.Handle
Get
Return hwnd
End Get
End Property
End Class
Still having the same problem.
I am creating an e-commerce website using asp.net and have a page which dynamically displays all the products.
The only 1 issue I have- In chrome the size of the image is correct as written in the CSS code but not sure why image width and height changes when I run the programme in FF- It becomes around 300 px each.
.productImage
{
width:150px;
height:150px;
vertical-align:central;
padding:10px;
border:10px;
border-radius:50px;
-moz-border-radius:50px;
-webkit-border-radius:50px;
display:block;
Text-indent: -9999px;
}
Can someone please help me?
I am designing an industrial hardware control program in C#, which will run for periods of 72 hours at a time talking over serial ports.
In psuedo-code, what I am trying to do looks like this:-
while(true) {
TalkToSerialPort1();
WaitForXHours(3);
TalkToSerialPort2();
WaitForXHours(1);
// etc
}
I have this code in a separate thread from my main console or GUI program and has to be run procedureally
It seems like Thread.Sleep() for long periods of time seems to be ruining my day! I am looking for a reliable way of sleeping for extended periods of time.
Any information would be helpful.
I trying to understand why when I create TcpListener server in c# I'm failed to retrive certificate chain from the client ssl connection.
I bought certificate from COMODO with folowing files:
Then I combined those files into one CAfile:
cat COMODORSADomainValidationSecureServerCA.crt COMODORSAAddTrustCA.crt AddTrustExternalCARoot.crt > cafile.cer
Next I create pfx certificate:
openssl pkcs12 -export -in new_api_coinpip_com.crt -inkey new_api.coinpip.com.key -chain -CAfile api.coinpip.com.bundle -out my-csharp-cert.pfx
And finally I writed simple test server application (SslServer.exe):

// Create a TCP/IP (IPv4) socket and listen for incoming connections11.
TcpListener listener = new TcpListener(IPAddress.Any, Port);
listener.Start();
while (true)
{
Console.WriteLine("Waiting for a client to connect...");
// Application blocks while waiting for an incoming connection.
// Type CNTL-C to terminate the server.
TcpClient client = listener.AcceptTcpClient();
ProcessClient(client);
}
}
static void ProcessClient (TcpClient client)
{
// A client has connected. Create the
// SslStream using the client's network stream.
SslStream sslStream = new SslStream(
client.GetStream(), false);
// Authenticate the server but don't require the client to authenticate.
try

sslStream.AuthenticateAsServer(serverCertificate,
false, SslProtocols.Default, true);
// Set timeouts for the read and write to 5 seconds.
sslStream.ReadTimeout = 5000;
sslStream.WriteTimeout = 5000;
// Read a message from the client.
Console.WriteLine("Waiting for client message...");

int bytes = -1;
do
{

// Use Decoder class to convert from bytes to UTF8
// in case a character spans two buffers.
Decoder decoder = Encoding.UTF8.GetDecoder();
char[] chars = new char[decoder.GetCharCount(buffer,0,bytes)];
decoder.GetChars(buffer, 0, bytes, chars,0);
messageData.Append (chars);
// Check for EOF or an empty message.
if (messageData.ToString().IndexOf("<EOF>") != -1)
{
break;
}
} while (bytes !=0);
return messageData.ToString();
}
public static int Main(string[] args)

RunServer (args [0], args[1]);

I have the following configuration for SimpleMessageListenerContainer in my Spring .NET consumer application. I would like to send the rejected messages to a dead letter queue or exchange. How can I do that in spring-net-amqp ? It is very easy to do that, in the java version of the library.
Thank you.

I'm trying to consume a .net generated WS from ColdFusion Page. Soap binding sytle of the said WSDL is document.
In the CF documentation, it is clearly mentioned that it is not possible consume such Web services.
To consume a web service that is implemented in a technology other than ColdFusion, the web service must have one of the following sets of options:
rpc as the SOAP binding style and encoding as the encodingStyle
document as the SOAP binding style and literal as the encodingStyle
Is there any work around available?
Reference: http://ift.tt/1eRLJBJ
I am trying to login on this website. Currently I'm using this code:
private string Login(string username, string password)
{
string formUrl = "http://ift.tt/1GIXYXM";
string formParams = string.Format("username={0}&password={1}&affiliate-button=Sign%20In", username, password);
HttpWebRequest req = WebRequest.Create(formUrl) as HttpWebRequest;
req.ContentType = "application/x-www-form-urlencoded";
req.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/43.0.2357.130 Safari/537.36";
req.Method = "POST";
req.Referer = formUrl;
req.AllowAutoRedirect = true;
req.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
req.CookieContainer = new CookieContainer();
byte[] bytes = Encoding.ASCII.GetBytes(formParams);
req.ContentLength = bytes.Length;
using (Stream reqStream = req.GetRequestStream())
{
reqStream.Write(bytes, 0, bytes.Length);
}
HttpWebResponse resp = req.GetResponse() as HttpWebResponse;
#if DEBUG
foreach (Cookie c in resp.Cookies)
System.Diagnostics.Debug.WriteLine(c.Name + " = " + c.Value);
#endif
return resp.Headers["set-cookie"];
}
I always get 1 set-cookie back. When I login to this website with web browser(Chrome) I get back 10 + local storage. I have tried to use CookieCollection as follows:resp.Cookies. But i still got back only one cookie.
The other problem is, that i cant download this file with the cookie I get. I only get back the login page. For downloading i use this function:
private void Download(string url, string fileName, string cookies)
{
try
{
HttpWebRequest req = WebRequest.Create(url) as HttpWebRequest;
req.Headers.Add(cookies);
req.Method = "GET";
req.Referer = "osu.ppy.sh";
req.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)";
HttpWebResponse resp = req.GetResponse() as HttpWebResponse;
using (Stream respStream = resp.GetResponseStream())
{
SaveToFile(respStream, fileName); //This reads the stream and writes to file
}
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
}
As I said before I used CookieCollection when I log in, I have also tried CookieContainer in this function like this:
req.CookieContainer = new CookieContainer();
req.CookieContainer.Add(cookies)
What am i doing wrong?
We have two ASP .NET web applications living on different servers. All authentication in our organization is done via Windows Authentication against Active Directory - so no username and password authentication in the web apps themselves.
We'd like to use claims based authorization and have these two web applications share information about what claims a given user has.
I'm trying to figure out how to go about this.
We have ADFS 2.0 and I know I can set up Federated Authentication using this...but where should my AD users' claims be stored and how are they hydrated and thus shared. Do the claims themselves end up in cookies after authentication?
Specifically, the scenario should be this:
I'm trying to load some of my project's assemblies dynamically.
When I load them via their file path like Assembly.LoadFile(path) I can get theirs defined types by calling GetTypes() method from loaded assembly.
var asm = Assembly.LoadFile(path);
var defienedTypes = asm.GetTypes(); //I've got all types without any error
But when I load them from memory like Assembly.Load(System.IO.File.ReadAllBytes(path)), I'm not able to retrieve defined types. So calling GetTypes() method causes an error:
Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information
And LoaderExceptions property contains all defined types.

I want to change text of any image with a user define Text in C# .NET The program should work like this: 1. Recocgnize text in any image 2. Put the text in string variable 3. Enter user define text 4. Again Insert the text back to the image
Can anyone suggest some solution. Any library that I can use to change text of a image
I have developed a windows service using local system as Account. I have used network path of file
FileInfo fi = new FileInfo(@"\\epm-server\penDocuments_LabMeds\" + Convert.ToString(dr["mrn"]) + "\\SyncedXML\\" + Convert.ToString(dr["xmlfile"]));
if (!fi.Exists)
boolFileNotFound = true;
A dynamic path of a file that is built from database.
It works fine when I run Windows Service in Debug Mode, but when I install it then fileNotExists returns TRUE always like the file doesnt exist but infact it does exist.
This is bugging me a lot now. Kindly help me why its not working. Its a server path. Its getting opened in my PC.
Thanks
I have 3 forms in my application : frmTrucks, frmEditTruck and frmEditContent. frmTrucks shows my Trucks in a grid. I add a truck, or choose one of the trucks from the grid to edit in frmEditTruck
public void Edit()
{
using (NestedUnitOfWork nuow = session.BeginNestedUnitOfWork())
{
Truck currentTruck = nuow.GetNestedObject(
xpcTruck[gvTruck.GetDataSourceRowIndex(gvTruck.FocusedRowHandle)])
as Truck;
using (frmEditTruck form = new frmEditTruck(currentTruck))
{
if (form.ShowDialog() == DialogResult.OK)
nuow.CommitChanges();
}
}
}
in frmEditTruck there are some text boxes for truck properties and two buttons. btnSave and btnAddContent. btnSave saves the changes (now.CommitChanges();). btnAddContent's click code is :
Truck truck;
Session session;
public frmEditTruck(Truck truck)
{
InitializeComponent();
this.truck = truck;
this.session = truck.Session;
}
private void btnAddContent_Click(object sender, EventArgs e)
{
TContent content = new TContent(session);
using (frmEditTContent form = new frmEditTContent(content, truck))
{
if (form.ShowDialog() == DialogResult.OK)
truck.TContents.Add(content);
}
}
it shows frmEditContent. I can Add content to my truck. the problem is when I press AddContent and then cancel it. After that when I press the save button on my frmEditTruck it would add an empty row to my Content Table. I want to fix this problem. how can I fix it? I'm not sure my problem is clear enough for you. Please let me know
public class Truck : XPObject
{
.
.
.
[Association("Truck-TContents")]
public XPCollection<TContent> TContents { get { return GetCollection<TContent>("TContents"); } }
}
public class TContent : XPObject
{
.
.
.
private Truck truck;
[Association("Truck-TContents")]
public Truck Truck
{
get
{
return truck;
}
set
{
SetPropertyValue("Truck", ref truck, value);
}
}
}
I am trying to mock a child collection validator, so i can write unit tests just for the validator itself.
So i have a validator that looks like this
public class ReportValidator<T> : AbstractValidator<T>
where T : Report
{
public ReportValidator(IValidator<Criteria> criteriaValidator) {
RuleFor(e => e.Name).NotEmpty();
RuleFor(e => e.MyList).SetCollectionValidator(criteriaValidator);
}
}
I have wrote a class in my test project to mock a validator, which looks like so
public class MockValidator<T> : Mock<IValidator<T>>
where T : class
{
public MockValidator()
{
this.Setup(x => x.Validate(It.IsAny<ValidationContext>()))
.Returns(new ValidationResult());
this.Setup(x => x.ValidateAsync(It.IsAny<ValidationContext>()))
.ReturnsAsync(new ValidationResult());
}
}
In my unit test i create my ReportValidator, by passing in a mock like so
public class TestReportValidator
{
private ReportValidator<Report> _validator;
[TestInitialize]
public void TestInit()
{
var mockListValidator = new MockValidator<ChildObj>();
_validator = new ReportValidator<Report>(mockListValidator.Object);
}
}
Now i have created my unit test to make sure that a report is valid like so
[TestMethod]
public void should_return_true_when_entity_is_valid()
{
var results = _validator.Validate(new Report
{
Name = "Test",
Module =
{
Id = 1,
Name = "Company"
},
MyList = new Collection<ChildObj>()
});
Assert.AreEqual(true, results.IsValid, results.IsValid ? string.Empty : results.Errors[0].ErrorMessage);
}
But i keep getting this exception
System.NullReferenceException: Object reference not set to an instance of an object.
Not sure what i am doing wrong, anyone shed some light on this?
I have a List<List<int>> set of data, with string representation like this (to give the idea!):
{{1,3},{-1,-3},{2,5},{-2,-5},{-3,4},{-5,4},{3,5,-4},{6,-8},{7,-8},{-6,-7,8},{7,9},{-7,-9},{3,8,-10},{-3,-8,-10},{-3,8,10},{3,-8,10},{4,9,-11},{-4,-9,-11},{-4,9,11},{4,-9,11},{10,11},{-1,6},{1,-6},{-2,7},{2,-7}}
I want to check if ,in all present numbers, exist a number or set of numbers which only are in positive form. I mean if in the whole data, there is 3 and -3 I should return false, otherwise I have to add 3 as a number which only is present as positive 3, in to another list. (Same thing for only negative number)
Here is how I am trying to do it:
First, generate a unique set of numbers and remove negatives:
private void GenerateCurrentExistingVariables()
{
_uid = new List<int>();
var all = _cnf.Data.SelectMany(list => list).ToList();
_uid = all.Distinct().ToList(); //make list unique
_uid.Sort(); //sort numbers
_uid.Reverse(); //reverse so highest numbers would evalaute first!
_uid = _uid.Where(i => i >= 0).ToList(); //remove negative numbers
}
Then I do something like this:
in a method, I call the code below:
for (var i = 0; i < _uid.Count; i++)
{
if (ExistOnlyInNegatedForm(_uid[i]))
{
onlyNegatedList.Add(_uid[i]);
}
if (ExistOnlyInPositiveForm(_uid[i]))
{
onlyPositiveList.Add(_uid[i]);
}
}
Which in turns calls the methods below:
private bool ExistOnlyInPositiveForm(int id)
{
for (var i = 0; i < _cnf.Data.Count; i++)
{
for (var j = 0; j < _cnf.Data[i].Count; j++)
{
if (_cnf.Data[i][j] == id)
{
return false;
}
}
}
return true;
}
private bool ExistOnlyInNegatedForm(int id)
{
var toCheck = -id;
for (var i = 0; i < _cnf.Data.Count; i++)
{
for (var j = 0; j < _cnf.Data[i].Count; j++)
{
if (_cnf.Data[i][j] == -toCheck)
{
return false;
}
}
}
return true;
}
This is too much code for this simple task and I feel that this is getting slower and slower when data grows larger...please let me know how can I improve this. Also I would like this to be done using LINQ at least for the sake of less lines of code!
I need to overcome this error:
There were not enough free threads in the ThreadPool to complete the operation.
I get it 80% of the time when queuing a bunch of Correspondence objects (with SSRS Reports) and sending them via Exchange WS. The reports are generated and emailed using a ThreadPool.
This is what the code looks like, it was built on .Net 2.0 hence no usage of TPL or Async/Await.
public static void QueueCorrespondence(ref Correspondence corr)
{
Queue corrQ = CorrespondenceQueue(corr.Medium);
// Create an AsyncOperation, using the CorrespondenceID as a unique id

}
}

} finally {
MailRoomArgs mra = new MailRoomArgs();
mra.CorrArg = corr;
mra.TransferSuccessArg = allReportsSuccessfullySent;
//Success or not, call the RaiseCorrespondenceSentEvent subroutine via this delegate.
scicqa.AsOpArg.Post(onCorrespondenceSentDelegate, mra);
}
}
}

return true;
} else {

return false;
}
}
}

Sending emails on the main thread works fine. After a couple of days on this I'm pretty certain the problem could be avoided if I didn't call Exchange WS on a worker thread as shown below.
It doesn't matter if I Save, Send or SendAndSave emails I still get the error:
private exchangeService = new ExchangeService(3); //Exchange2010 SP2
public void SendCorrespondence(ref Correspondence corr)
{
exchangeService.Url = new Uri("http://ift.tt/1dpOkBc");
exchangeService.UseDefaultCredentials = true;
string[] emailAddresses = corr.SubscriptionObject.SubscriptionRecipients.EmailAddresses;
EmailMessage message = default(EmailMessage);
message = new EmailMessage(exchangeService);
if (emailAddresses.Count > 1) {
message.BccRecipients.Add(string.Join(RECIPIENTS_SEPARATOR, emailAddresses));
}
else if (emailAddresses.Count == 1) {
message.ToRecipients.Add(emailAddresses(0));
}
message.Subject = corr.SubscriptionObject.EmailSubject;
EmailAddress fromSender = new EmailAddress();
fromSender.Address = _instOpsSharedOutlookMailAccount;
fromSender.Name = _instOpsSharedMailAccountName;
fromSender.MailboxType = MailboxType.Mailbox;
message.From = fromSender;
foreach (ReportBase generatedReport in corr.GeneratedReports) {
message.Attachments.AddFileAttachment(generatedReport.GeneratedDocument.FullName);
}
message.Body = new BodyType();
message.Body.BodyType = BodyType.HTML;
message.Body.Text = corr.SubscriptionObject.EmailTemplate;
if (corr.SubscriptionObject.SendToDraft) {
//Saving causes the problem !!!!!!!!!!!
} else if (Convert.ToBoolean(Code.GetCodeTextValue(PARENT_CODE, "ExchangeSaveMsgOnSend", RETURN_DEFAULT_STRING_IF_NO_DATA, "True"))) {
//Sending and Saving causes the problem !!!!!!!!!!!
message.SendAndSaveCopy();
} else {
//Sending causes the problem !!!!!!!!!!!
message.Send();
}
}
In fact using any Exchange methods, eg: ExchangeService.ResolveName(logonID) produces the error when called from a thread in the pool.
Does anyone know how I can send the emails without exhausting the ThreadPool? I don't want to re-architect this code too much, but would be happy to implement a simple way to avoid sending the email on a thread if anyone knows how.
The problem does not occur with Lotus Notes (yeah I know... lol!). I was using Exchange WS to get around the Outlook nag when an external program uses it to send emails. I would prefer not to use the Outlook Client but if there is no good solution I guess I will have to. Using Smtp client is not on the cards (as saving drafts in group folders is a major feature). I have also tried reducing the maximum number of threads in the ThreadPool but as I suspected that doesn't make a difference.
Any help would be much appreciated!!

Are there any differences between MongoDB.Linq vs C# Linq without Join mechanism? In my application, MongoDB is used as storage unit and Client Side Application has been coded via C# Linq Driver.
So, I want to store MongoDB query results to another collection and I want to let Client Side Application for querying Linq.
If there are big differences between C# and MongoDB Linq drivers, it will be big failure for both server and client side applications.
