        even those process is not been opened and i tried changing the directory but same error occured... i cant figure out the problem.. plz help me...


It could be any process that has the file open - tell me, by any chance did you run through a debug on this process before that opened the file but exited the process before it had a chance to close it? In which case it could be your orginal debug run which has locked the file.

If you are not going to modify the file in anyway try opening it in read only mode.

Also, try rebooting the machine and see if it will let you access it then - if so, whatever process locked the file has ended. I think in later versions of Windows there is away to see who/what has a file open, but I can't remember exactly how you do it (under the right mouse click?)

Note that the process which has the file open could be your process, if you've opened it before and failed to close it or try to open it again before disposal completes.

I'd strongly recommend downloading and learning how to use Process Monitor to troubleshoot these types of errors. That tool has saved me so many times in both development and IT support.
