Parent Destroy Child

I want to call a child controls unload procedure whenever the Parent is destroying itself.


This brings me to wonder.
I do not handle WM_DESTROY for the parent.
I just handle WM_CLOSE which calls Unload() which calls DestroyWindow(hwnd).

When the unload() runs, it checks to see how many parents windows are still open before PostQuitMessage....

When a parent is destroyed what does it send to the control?
my controls are subclassed, so I have to capture anything???

I think you should only call PostQuitMessage on WM_DESTROY which will post after DestroyWindow(hWnd)

Has nothing to do with your question but I think WM_CLOSE->PostQuitMessage(0) is incorrect.

WM_CLOSE->DestroyWindow(hWnd)->WM_DESTROY->PostQuitMessage(0)
