Do not use keybd_event().  There is no way to gaurantee which window it
directs keystrokes to.  If the user switches windows while keybd_event() is
still running, the keystrokes will go to the wrong window.  You have to use
SendMessage() to ensure the proper window is used.  Also, use WM_KEYDOWN/UP
instead of WM_CHAR.

That is because you are sending the messages to the wrong window.  You are
sending them to the browser's container window when you need to send them to
the edit control of the <input> element itself instead.

You do not need to do that.  There is nothing "special" about those
characters.  WM_CHAR handles them just fine without special handling.

No.

No, but then again it doesn't need to.  All that script does is disables the
upload button and then pops up a progress window during the upload.  Since
you would be programming to the HTTP protocol directly, there would be no
upload button at all (except in your own UI, if any), and you could show
your own progress information as you have direct access to the connection
that is sending the data to the server.

All the more reason not to use TWebBrowser at all for that.  It would be a
major bottleneck in that process.  If you go to the HTTP protocol directly,
you can automate the uploading much much cleaner, and eliminate Microsoft's
UI altogether.
