I have downloaded DirectX SDK..
And i have checked all given examples..
But no one was able to do what i m asking....
It was irrelevant to the solution of my problem

I have two files one is WAV and other is AVI without sound..
I want to add WAV into AVI ....

My question is very simple...
But i have searched in all reputed Search Engines..
But not a single query helped me ......
