When dragging a file from Windows Explorer into other apps, I now get a nice icon of the files I drag. I cannot remember this from previous Windows versions so I was hoping that they finally implemented the equivalent of the Translucent Drag Manager where you can associate a transparent image with the drag contents. Does anyone know anything about this?
A:
This isn't really new to Vista and/or Win7. You can create such a drag image with the IDragSourceHelper interface. Or you can create your own manually without that interface.
All you have to do for this to work is to implement the IDataObject::SetData and IDataObject::GetData methods so that they allow custom formats.
