Drag-n-Drop to Folder or Desktop

I have a form that displays a list of bitmaps. I have read the MSDN docs
regarding drag-n-drop operations, and have reviewed some examples online on
how to do this, but the examples I have seen thus far only show how to
create an internet shortcut file.

When the user drags an image from the form to the desktop, I would like to
either save the image using a default filename (if possible) or show the
Save As dialog so the user can enter a name for the file themselves. So,
the form with my images (which are in-memory bitmaps and are not stored on
the file system) needs to be able to have the images dragged from the
ListView control (which are ListViewItem's of course) and dropped onto a
specified folder or the desktop (actual folder or desktop, not part of my
app)...

Thanks,
Mythran

Mythran,

I've been diging into this problem couple of years ago. Back then I end up
with the conculsion that this is not possible in .NET (at least not at
reasonable mout of work). I posted back then my findings in the newsgroup,
but unfortunately I cannot find the post right now and I don't remember any
details.

Just keep in mind that this might not be possible with .NET.

Bah, anything's possible, even if I have to handle it all myself :P

That's what I found back then for .NET 1.x I don't know if there is
something new in .NET2.0 that could help with this. We all will apprecaite
if you post your solution if you find one.

I didn't want to discourage you, just wanted to warn you in case you decide
to change you design instead of spending a lot of money and time solving
this.

Well, being that this is a side-project that is just a utility program for
me that reads an icon file and displays all of the images stored in the icon
as bitmaps, it's not all that important. I just wanted to drag-n-drop the
images onto a folder and then have the program create the images in this
folder...I can do it by creating temporary files and using the
DragDropEffects.Copy effect and use the DataFormats.FileDrop data format and
specify the temporary file path as the data...this should do the trick!

Cheers,
Mythran
