OnSetCursor and the keyboard
-
I am trying to have the cross cursor apear when you press down the control key. In the MSDN it says that message controls the mouse message number. When I run this code it does not recignise the key.
BOOL CClusterSimulationView::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message) { if (message == MK_CONTROL) { hCursor = LoadCursor(NULL, IDC_CROSS); SetCursor(hCursor); } else { hCursor = LoadCursor(NULL, IDC_ARROW); SetCursor(hCursor); } return true; } -
