My MFC app has a modeless dialog. I'd like to know when the user clicks outside of the dialog (at which time I'll hide, but not destroy, the dialog). I'm not receiving the WM_KILLFOCUS message.
I used the ClassWizard to handle the WM_KILLFOCUS message. It correctly added the ON_WM_KILLFOCUS() message map and handler function. However, when I click outside the dialog (and the dialog shading clearly changes to show that it no longer has the focus), OnKillFocus() isn't called. When I click an OK button in the dialog (which calls CDialog::OnOK();), OnKillFocus() is called.
