You also need to include the message in your receiving windows message map via on_message.

Syntax
// inside the class declaration
afx_msg LRESULT OnMyMessage(WPARAM wParam, LPARAM lParam);

...

#define WM_MYMESSAGE (WM_USER + 100)

BEGIN_MESSAGE_MAP(CMyWnd, CMyParentWndClass)
ON_MESSAGE(WM_MYMESSAGE, OnMyMessage)
END_MESSAGE_MAP()

LRESULT CMyWnd::OnMyMessage(WPARAM WParam, LPARAM LParam)
{
return (LRESULT)0;
}
