Hi, I made this function a while ago and it was working.

Because of my computer is infected by a virus so I have to reinstall my comp to make it return to normal. After I reinstall my computer my avi function did not work. I have search the internet for a new version of the .dll and I install it but it still not working. the problem seems on fAVIDraw function in this line    invoke AVIStreamGetFrame,[esi].pGetFrameObject,FramePos because it always return null. Anybody know how to solve it?

I also upload the include file and the lib

Was your previous installation using the vfw32.lib from the PSDK?

The one from your attachment is smaller than the one from the February 2003 PSDK.

What about (re)installing DShow and VFW codecs to decompress the video  :toothy ?

The one I use, and I think the last one that will work under Windows 98/ME, is here.

I make it working. Have fun of this code.
