Why does my app not receive the WM_CREATE message?

I want to get notified of new windows before they are shown.

Therefore I subclass my application and listen for the WM_CREATE message.

I am using Paul Caton's VB6 subclasser.

Subclassing and listening to Windows Messages usually works fine for me, but I just don't receive any WM_CREATE message.

Neither when I open any additional window in my app nor when other apps show new windows.

What am I missing?

Thank you!

You subclass only one window? `WM_CREATE` is delivered to the created window, not to the creator. – GSerg Jun 11 '22 at 14:46
