Yogesh, this is third post of yours.... and you are still not clear what you need...

as Colin posted, which operation you need after the drag and drop....

if it is copying files( i assume this - Copping)
then have a look at this article....

Drag and drop, cut/copy and paste files with Windows Explorer

Have a Happy Coding.....

1. Stop calling everyone sir, we are not a bunch of knights here you know
2. Stop posting the same friggin question every 5 minutes
[EDIT]
2 1/2. Why are you even posting when you clearly are not taking anyones advice anyway?
3. Finally, and most importantly, QUIT TRYING TO BE A PROGRAMMER BECAUSE YOU CLEARLY ARE NOT CUT OUT FOR A LIFE OF USING YOUR OWN BRAIN TO SOLVE A PROBLEM WHICH IS WHAT BEING A PROGRAMMER IS ALL ABOUT!!!!!!!!!!!! (12 should do it, now to bold or not to bold...)

4. Why have you not quit yet?!?!?

That's not the idea. This site is here to help people, including you. Reposting the same question repeatedly isn't going to get you the help you seek though. Neither is not following the advice you've been given and not explaining why.

If the advice given was incorrect, then you should post back to the same thread with an explanation of why it didn't help. If it was a problem with the way you expressed the problem, edit the post and the subject will change to modified so others can see it's changed and will reread the question.

checked file download from gridview

31-Mar-09 2:10

well after a quick google search, see here [^]for details.

I found that WAVE files can be stored in a number of different encodings, see here [^]for details.

So I would suggest finding the encoding you have first. Then you can look into the format of that encoding. For example MP3 encoding details can be found here[^].

Then you can parse the file and change the data you want then save the file again. Simple enough in theory, but are you prepared to attempt the work is the real question.

No one is auditing your entire code, especially when it isn't formatted and put into pre tags, never mind the fact that this isn't the asp.net forum.

Check out the CodeProject forum Guidelines[^]
