The only way that would happen is if your code is not setting up a top-level
window that is capable of receiving broadcasts in the first place.  Your
other uses of PostMessage() send the message to a specific window or a
specific thread (PostMessage(NULL, ...) is the same as calling
PostThreadMessage(GetCurrentThreadId(), ...)) without any broadcasting,
which explains why the peeking works fine for them.

That is not the proper signature for a window procedure.  You left out the
calling convention.  The default calling convention is __cdecl when no
convention is specified in the code.  A window procedure needs to use the
__stdcall convention, ie:

    LRESULT __stdcall WndProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM
lParam)

Or:

    LRESULT CALLBACK WndProc (HWND hWnd, UINT msg, WPARAM wParam, LPARAM
lParam)
