I can speak english a little , please don't mind
I want to implement Drag&Drop using COleDataSource and COleDropTarget。
So, I declare a COleDataSource in CXTPTaskPanelEx:CXTPTaskPanel extend class
And, I use COleDataSource.DoDragDrop in CXTPTaskPanelEx::OnLButtonDown
But, unexpected situation happened...
When i drag or click item in CXTPTaskPanel&Group, the respond all confusion, delay and wrong...
It's OnTaskPanelNotify results also delay and wrong.
What's the reason that?
How can i implement Drag&Drop in CXTPTaskPanel? Don't use COleDataSource&COleDropTarget method?
Thanks all!
