Please, someone help me.

I am getting this error message when I start debugging my windows application program .
I need this very urgently.

Error 1 Unable to copy file "C:\raj\vbpro\raj_BLL\bin\Debug\Raj_BLL.dll" to "bin\Debug\.dll". The process cannot access the file 'bin\Debug\REQUE_BLL.dll' because it is being used by another process.

There can be several reasons for that. One of them: DLL could be loaded by your own application process which was not terminated and runs in background. Check it up using Ctrl+Alt+Delete => Task Manager. In certain situation, Visual Studio can keep it loaded with its debug host; try to close all of its instances. It could be something else. If you still did not find the reason, some system utility can help. Try "WhoLockMe.exe" — it easily solves such problems.
