I have a treeview control and a visio control in my application.I need to create a drag drop effect such that when i click my mouse and drag a node from the tree view control nd release the mouse when its somewhere over the drawing control i want a specific shape to be dropped.But as the visio control doesnt have any drag drop event associated with it how do i go about doing this?
Maybe this (http://msdn.microsoft.com/en-us/library/aa342169.aspx) will help
Or maybe this (http://www.experts-exchange.com/Programming/Languages/Visual_Basic/Q_20362741.html) has some info ( didn't look true all the code of this one though so I'm not sure )
