Before my project design and output works fine. Now, when I open one of the form of my project, it displays at http://stackoverflow.com/questions/222649/winforms-issue-error-creating-window-handle the Task List which states "Error creating window handle." I did to step through the code and it returns no error and functional output. My problem is I can't see one of the form at the design time. Last edited by bevz; Sep 21st, 2005 at 07:55 PM.

I'd say the http://www.vbforums.com/showthread.php?361359-RESOLVED-Error-creating-window-handle form's resource file has become corrupted. You could try right-clicking the form in the Solution Explorer and selecting Exclude From Project, then right-clicking the project and selecting Add Existing Item to re-add the form to the project and (hopefully) regenerate the resource file. If this doesn't work, you could do the same thing again but this time delete the RESX file for the form before re-adding it. You might want to make a backup copy of the solution folder before trying this, just in case. 2007-2016 Why is my data not saved to my database? | MSDN Data Walkthroughs MSDN "How Do I?"
