Hi I obtain an exception sometime when I move a floating window (see the exception message at the end of my post).

In order to debug my application I would like to override the WndProc method to check what happen when m.Msg == WM_MOVING (where WM_MOVING = 0x0216). I tried to override the WndProc method of the usercontrol that is contained in your floating form but there is no WM_MOVING message on the usercontrol. I suppose that it is your floating form that handle the WM_MOVING message, right? How could I intercept the WM_MOVING message?

I saw that the docking manager has event for OnStart and OnStopDragging but there is no OnDragging event.

Thanks you

It seems that its WM_MOVE = 0x003 instead of WM_MOVING that I need to monitor.

Hi Jonathan,

Thank you for your interest in Essential Tools.

I am unable to reproduce the issue with the floating form movement. WM_Moving message has been handled in our Floating form. Can you please create a Direct trac incident and provide me with a simple sample to reproduce it from my side? This will help me providing you with possible suggestion on the same.
