How to insert animated GIF into RichEdit?
Please tell us what IDE, OS and Compiler you are using. This will make it easier to try and answer your query.
You must use the
EM_GETOLEINTERFACE message to obtain the RichEdit's IRichEditOle interface and the
EM_SETOLEINTERFACE message to register an IRichEditOleCallback interface that the control uses to obtain the Ole data.
There is a MS support page that addresses this very issue for a bitmap object at
http://support.microsoft.com/kb/220844
To do an animated GIF is much the same (you must decode the GIF into its component bitmaps, which is somewhat involved but not difficult, and you can get an actual GIF LZW decoder algorithm by searching the web; or you can find a library that does it for you...).
The main difference is that you will need to periodically update the bitmap displayed.
I've never done this myself, so I don't know of anyone who has... a little googling might get some useful tips.
Good luck.
