[bhadram r. <bha...@ya...>]

Dear per and friends,
                           I'd problem with vc++ compiler. I'm addding the haeder file as project->add to project-> and creating header file. But sometimes the compiler says as 
cannot save the file the file may be in use by another application .
 
Actually I couldnt understand why it is happening. What does it mean and why it is behaving sometimes like that. Waiting for your responce.
 
Thanking you,
yorus truly,
bhadram
