If your application performs any non-UI processing on the thread that controls the user interface, it may make the app seem slow and sluggish, frustrating users. But writing multithreaded apps for Windows has long been restricted to C++ developers. Now with the .NET Framework, you can take advantage of multiple threads in C# to control the flow of instructions in your programs and isolate the UI thread for a fast and snappy user interface. This article shows you how. Also, it discusses the pitfalls of multiple threads and presents a framework for safe concurrent thread execution.

To write GUI applications for Microsoft .NET you'll use Windows Forms. Windows Forms are a new style of application built around classes in the .NET Framework class library's System.WinForms namespace. They have a programming model all their own that is cleaner, more robust, and more consistent than models based on the Win32 API or MFC, and they run in the managed environment of the .NET Common Language Runtime (CLR). This article details what Windows Forms are all about, from the programming model to Microsoft Intermediate Language and the JIT compiler. Two applications using forms, event handlers, anchors and persistence are built step by step.

Issue:

A Windows Forms application developed with VB2008 Express that has been successfully run on two Windows XP systems and a Windows 7 system fails to run on two of two Windows Vista systems tried so far.

Details:

Attempting to run the app on a Windows Vista system results in a system dialog box titled, Microsoft Windows, with the message, A problem caused the program to stop working correctly.  Windows will close the program and notify you if a solution is available.  A single button at the lower right of the dialog contains the text, Close Program.
The initial form of the application never displayed and the dialog above appeared with little delay after attempting to start the program.

The program uses an SQL Server Compact Edition 3.5 database and the program is compiled to include the following .DLL files so the user does not need to install SQL ServerCE.
sqlceca35.dll
sqlcecompact35.dll
sqlceer35EN.dll
sqlceme35.dll
sqlceoledb35.dll
sqlceqp35.dll
sqlcese35.dll
System.Data.SqlServerCe.dll

The Load event of the initial form causes a DataSet to be filled from the SQL CE DB.
