i added some activeX control on my CFormView (part of SplitterWnd), i wanna to change its position and size according to the size of its parent (CFormView),
meaning strech it all over the form view
in OnInitialUpdate() i did:
::SetWindowPos(m_dataQCtrl.m_hWnd, HWND_TOPMOST, rect.left, rect.right, rect.Width(), rect.Height());
but it didn't work, why?
