Drag and Drop in Visio

[Bony Baba]

I have a listview on my form whereas my form is the child window of microsoft
visio Application. I want to drag image from my listview and drop in visio
drawing.

The problem is that how we track the mouse up events in visio because
mouseup event does not fire without mousedown event. and my mouse down events
fired on my form.

Plase help if someone have idea about that!

Thanks

You'd better use the real OLE drag-n-drop and not mouse events.
I mean, take a look at IDataObject and the stuff like that.

In Graham's book (Visio 2003 Developer's Survival Pack) this is
enlighted quite well.
