Attempted to read or write protected memory. When I call showDialog method of openfileDialog
My project was created in winxp and now migrated to windows7. I am getting a weird exception while click on the openfiledialog icon in my project and the application crashes after this. This only happens when I create a release build and install that build in windows 7.
The setup is also created in the windows 7. I do no get this exception when run the code in the debug mode.
I am setting the initialdirectory property of the openfiledialog to desktopdirectory.
Below is the exception trace i caught in the windows event viewer.
Application: projectname.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.AccessViolationException
