    Hello Is possible to catch a system event if mouse is in Drag'N'Drop mode? I mean an event when PC user is dragging something between two application f.e. from AcrobatReader to Photoshop and I want catch this event from my app. Or the one possible solution is asynchronously track mouse way and buttons... Thanx

      You could use SetWindowsHookEx[^] to install a global hook of type WH_CALLWNDPROC or WH_GETMESSAGE to intercept the WM_DROPFILES message that is sent during the drop event of a drag and drop operation.
