Displaying an animated GIF file in an MFC application
Jim Nobilini
Does anyone know how to display an animated GIF file in an MFC
application, or is there a better format that I should use to animate?
And if there is a better format, where can I get the tools to do so, and
how would I display this new format in an MFC app?
Thanks,
JIM

Actually, Unisys will be glad to license the gif format to you, just as
they did for (to?) Compuserve. In nice round numbers, think 2% of
sales.

You will have to write your own function for that. If you have J++, the app
wizard can automatically create an animation. But it's not using a animated
GIF file. You easliy can port the Java code to C++, even if you are not an
Java expert. If you're using *.gif files you will have to provide a
conversion from gif to dib. If you want to sell the program you'll have to
consider that you will have to get a license (from Compuserve I think).
BTW The J++ 1.1 trial version can be downloaded from Microsoft. 22
MByte..., it has no expiry date, all that is missing to the regular version
is database support.

Only americans must pay. (Such silly patents don't apply anywhere in
the rest of the world)

This isn't true, Robert. The patent applies to all software sold within
the USA, not simply to Americans. If you, in Germany, write a GIF viewer
and then sell it to Amercian customers, Unisys can and WILL come after
you!

Yes, there's a better format, it's called "AVI". You can display AVIs
through one of a half dozen methods, at least; the easiest (full featured
method) is, in my opinion, the MCIWnd set of functions. The easiest
(restricted functionality method) is the CAnimateCtrl MFC class (which
wraps the Animate Common Control).

Hi, there. Without getting into discussions of what bastards the Unisys
are, how about using an AVI file format? There are many multimedia books
out there that show you (C and C++) how to read/play the AVI.
