Posted on 2006-06-12
I have question, and hope you can help me.
That is, I write a program for install DIVX MPEG-4 codec for audio and video.
After running my program , i check the video(audio) codec by opening Device Manage and click right mouse in Video Codec and choose Property tab, then i see the line DIVX MPEG-4 video codec.
And now , i will run my program on another PC.
So , i want to my program can check this codec has existed on system or not?
If it has, i will not run Shellexecute and will run if it has not? Can you direct me how to check this codec ?
