Hello,
When I choose to use the DND_EXACTIMAGE flag in a call to DoDragAndDrop, how can I make a visual difference between a DND_COPY and a DND_MOVE operation?
Would it not be better to have an overloaded version of this function, accepting two images (or even three, one more for the 'no drop allowed')?
Or do I overlook something?
Regards
Frank De prins

Well, I must say I preferred the first one.
I already tried it out, locally (only for Windows, though) and what I did was:
Change the current version with one image to 3 images and change the code to use the right image for each of the 3 actions.
Add a new version with one Image (conform to the old, unmodified, one) that just calls the modified one with 3 times the same image. That way, old code is not broken.
I think having 3 images gives the most flexibility.
I attached a patch file to show my mods.

You are right, this needs fixing.
