#### drag/drop files with different name

I have a CListCtrl which contains a list of files from a directory
tree. I have it so that you can drag-and-drop files from the list into
an Explorer Window, and files get copied just fine.

What I would like to do is rename the destination file. So if
F:\foo\bar.txt is dragged on to the Desktop, I'd figure out that it
should be called qux.txt instead, and that's what should appear on the
Desktop.

Is there a way of munging my data source object? Should I try to find
the drop destination instead, and try to rename it there?

Any help is appreciated.

Thanks,
Gopi.

If you are dragging it from your application you can change the name of it
when you create the drag object.  If you are dragging it onto your
application you can change the name there (in your application) when it is
dropped.

So, you'll have to do the figuring out while the drag is being created.

Okay, I'm not much of a Windows programmer. My drag-drop code was
pretty much cargo-cult from here:

<http://www.codeproject.com/shell/explorerdragdrop.asp>

My app is just a data source, not target.

I can't rename the files before the drag, and revert them after,
because the source filesystem is read-only.

As far as I can tell, I'm only populating the DATASOURCE struct with
the source filenames. How would I tell it a new name? My guess is, I
can't just use the new name in there, because the target won't know
what to pick up.

Yeah that's true.  From what I know (which isn't all that much compared with
universe and all) you would have:

1. Write some code to hook into when you drag it and rename it there by
popping up a dialog. You would have to put the right name in the data source
and rename the actual file before finishing the drag.
2. Hook into the Explorer (perhaps a namespace extension) to rename it
there.
3. Live with the original name :o)

OPENFILENAME w/ wierd file history popup?
