I really do not know what to do about this. Often, when I run Forms programs with Visual Studio the application crashes with an exception like this "AccessViolationException". I never exerienced any problems with other standard applications like e.g. Word, Excel, Outlook, only self written programs in C# seem to suffer from this. Most of these applications then contain either something like a ToolStrip or a DataGrid which then after an exception like this are only represented by a white rectangle with a red X. The controls itself are standard out of the box.
I ran the Microsoft Memory Diagnostic today, but it did not find anything wrong with my memory. Does anybody has an idea what may cause this exception
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
