I have a really huge project with hundreds of thousands lines of code. My application has a complex graphical interface.
For some reason, sometimes my main form is resized, and I just don't see why / how this happens.
To track down the reason for the resizing, I installed a window subclass.
Private Sub iSubclass_WndProc(ByVal bBefore As Boolean, bHandled As Boolean, lReturn As Long, ByVal lng_hWnd As Long, ByVal uMsg As eMsg, ByVal wParam As Long, ByVal lParam As Long, lParamUser As Long)
These are the parameters of the window message for WM_SIZING when this undesired resize occurs:
wParam = 9
lParam = 1697980
lParamUser = 0
The resizing only occurs only like once each 2 hours, so debugging is really difficult already.
How could I track any further who / which function is responsible for the resizing?
