Confused about Drag/Drop

There seems to be two ways to put things on the clipboard ( I don't mean
different formats): SetClipboardData and OleSetClipboard

If I want to get data off the clipboard do I care how it was put there?



What about Drag/Drop; is there more than one way for the source to make data
available
Is it always OLE?

What's the relationship between WM_DROPFILES and HDROP. I think HDROP is
the OLE way.
But can I get the data using either or do I have to know what the source
did?

The bottom line is, if there are two ways and, as an example, I drag from
Word (or the Shell) to my app
how does the app know which way to extract it?


Thanks

Hi
you can use DoDragDrop, look at this sample source It is a widows

re: Confused about Drag/Drop

Thanks, I've copied your post and saved it to study after I close this.

But I hope someone answers the questions I asked in my post.

I'm confused about the interplay of the different options.

Are they really different or is just the UI different?


Thanks again
