I have been tasked with a project where I am to add a new application and have it within an older application (web applications). This is an internal application and management decided that they want it wrapped in this older app. The older application is a ASP.net web app using the 3.5 framework. My original plan was to use jQuery and...
I'd like to retrieve the state of the Ctrl keys in a place where I don't have a form. Normally to get a key state I'd use Control_KeyDown / KeyUp events. However, the code that needs to know whether Ctrl is pressed is outside any form. There is a form displayed, but the code is supposed not to depend on that form but finding the key sta...
Actually I intended to ask the following question: For an executable that lies in a directory defined in %PATH%, how can I find out in which of these directory it is found? because I need to run Excel from C# using Process.Run(...), and just indicating "Excel" works fine: Windows seems to know where to find it. However I need...
This is a two part question. First, let's say that I have a function that is executing in a another thread: private AutoResetEvent StopEvent = new AutoResetEvent( false); public void WorkerThread() { while( !StopEvent.WaitOne( 10)) { a(); b(); c(); } } Now I want to pause this thread. Thread.Suspend is out of the qu...
I am trying to display a "Yes / No" messagebox from codebehind in C#. I want to call an "AddRecord" procedure if the user clicks "Yes", and do nothing if the user clicks "No". Ideally, I want to use the code below, but from codebehind: OnClientClick = "return confirm('Are you sure you want to delete?');" I search on SO and google,...
I am eager to find some solid (free, Open Source, or tutorial/example) code to make a WPF Combobox do autocomlete/autofilter as the user types. But everything I've tried so far has had some sort of problem... A Reusable WPF Autocomplete TextBox came close, but I can't get it to work with more than one filter (more info here). WPF autoc...
I am trying to create a customized messagebox using javascript but not getting too far. string txtConfirmMessage = "On " + DateTime.Now + ", "; txtConfirmMessage = txtConfirmMessage + sUserID; txtConfirmMessage = txtConfirmMessage + " added this record. Do you want to continue? "; btnSubmit.OnClientClick = @"return confi...

This is similar to already created thread here: http://stackoverflow.com/questions/3179028/mixed-mode-assembly-in-net-4 Using the app config, I was able to force the assemblies to run on .NET 4. On an XP Machine, I installed just the .NET 4 (without .NET 3.5 or 2.0) and tried to run the built application. It fails to load the mixed mode...

I have a unit test for some code that occasionally throws a "The transaction has already been implicitly or explicitly committed or aborted." exception. Google gives me lots of wonderful hits but none that I've read seem to apply. If I run the unit test locally the exception is never thrown. If I run it on the build server manually the...
I've been searching for a while but it seems to be difficult to find any definite answers on how to recover from exceptions thrown by calling NamedPipeServerStream.BeginWaitForConnection. I have an application that sets up a named pipe server on a well known name and listens for messages to perform certain actions. It works fine and da...
This line of code works on my computer (64-bit Win7). I tested on XP 32bits in a VM. It works fine. static bool HasExpire { get { return DateTime.Now >= DateTime.Parse("10/20/2010"); } } However on a client machine it throws this exception: An unhandled exception was generated during the execution of the current web request. Inf...

I am about to start a new project. Using VS2010, Silverlight 4, and RIA Services are a given. However, due to the web server we have available, there is some question of whether we can use .NET 4 or whether we will have to stick to .NET 3.5. I know that RIA Services can work with .NET 3.5. But what I'm curious about is whether there ...

I need to create XML serializer classes for approximately 65 XSD files, for which I am using Microsoft's XSD.EXE to generate the C# code... However, I keep running into Window CMD's character limit in the resulting output file (in which XSD.EXE combines the name of every XSD included): "The specified path, file name, or both are too lon...
