[Solved] Markup Events Crash on Form Unload Me

I had a support ticket open for a problem that I was having when using Markup events in the ReportControl. In my program, I wanted to unload the form hosting the reportcontrol when a markup image was clicked. Typically, this would be achieved simply by calling Unload Me. Unfortunately, this was crashing the IDE and generating an error report in the compiled EXE. Mark from Codejock suggested this workaround and it works well:

Private Const WM_CLOSE = &H10 Private Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long Public Sub XamlMouseDown(Reserved1 As Object, Reserved2 As Object)   ' Sample event raised from XAML in ReportControl   PostMessage Me.hwnd, WM_CLOSE, vbNull, vbNull    ' Use this instead of Unload Me to prevent crash End Sub

In case anyone else encounters the same problem, please use this workaround.

Happy New Year everyone!
