I have an SDI app that needs to make use of drag and drop. I have
anywhere from 1-256 square bitmaps that represent lighting fixtures
that I want to be able to drag around the client window and drop them
at appropriate locations. I've used apps where you can hold down the
Ctrl key and click on the objects and they stay marked. Then, you can
drag the whole mess and drop it where ever provided it does not
overlap anything else.
1. Does OLE2 support this?
2. Is the "multiple mark" feature automatic or do I have to implement
3. Does the OLE2 drag 'n drop offer something that regular drag 'n
drop does not?
Any additional comments/observations are always welcome.
