Next: How do I find out how wide the form's border is

I have to admit I thought I would be able to find this question on Google
Groups or Planet Source code, but after several hours of searching I have
come up blank. Maybe I am not searching correctly. :-)

I have found a lot of examples of drag and drop to a form, but none on how
to drag and drop to an icon placed in the system tray.

I really thought that just activating the OleDrop on the the form would
allow me to drop files to the icon. Silly me for thinking it would be that
simple. Can anyone point me in the direction I would have to go to get the
drag and drop that works on the form to respond to the NotifyIcon.

Thanks,
Norm

I don't think this is possible.

I've never seen any application that does it or seen any interfaces/APIs
that would suggest it is possible.

It won't use the forms properties as it's not tied to a form at all
(beyond an hWnd to send messages to)

Not sure if it's possible to drag a file to system tray icon. You
can, however, drag a file to a desktop or taskbar icon to open if you
have Command$ parsing in your program.

I am not sure if this is possible, but the term used for this is "Drop
Target". The easiest thing to do is to make a borderless form, say of a size
of 32x32, or 64x64, and make it topmost. Add a right click popup menu so the
user can exit from it(See "PopupMenu method" in MSDN).

Another choice, is to create an icon on the desktop and make it a drop
target, but this can be easily covered by other windows. Download "Shell
Extensions", "Shell Extensions [FIX - Missing files]", and "OLELIB.TLB - OLE
interfaces & functions v1.7" files below. This install many shell extension
samples, including a desktop icon acting as a drop target called "Edanmo's
File Shredder". When you drop files on it, it prompts you if you really want
to delete the files. This works like the Recycle Bin.

This is also kinda backed up by the "show hidden icons" not being
activated when you drag over it (on route to dropping on a hidden icon)
