When you want the Sysmenu to be visible

SetWindowLong(GetSafeHwnd(),GWL_STYLE,WS_SYSMENU | GetWindowLong(GetSafeHwnd(),GWL_STYLE));
RedrawWindow(NULL, NULL,RDW_ERASE | RDW_INVALIDATE | RDW_FRAME | RDW_ALLCHILDREN);

When you don't want the Sysmenu to be visible

SetWindowLong(GetSafeHwnd(),GWL_STYLE,~WS_SYSMENU & GetWindowLong(GetSafeHwnd(),GWL_STYLE));
RedrawWindow(NULL, NULL,RDW_ERASE | RDW_INVALIDATE | RDW_FRAME | RDW_ALLCHILDREN);

Hope this helps you :) Knock out 'T' from CAN'T , You 'CAN' if you think you 'CAN' :cool:
