Hi,

I am getting this error, when ever i am linking a new form in mdi Parent ,
After giving build the error is raising like this,
Unexpected error writing metadata to file Path name of my project exe,'Not enough storage space available to complete this operation.

But if i closed my project and then when i am opening it again this error is not coming?

may i know the reason why this error is coming ?

Are you using VS 2005? Because it is a known bug in that version. If possible you can try moving your build to a new folder. If you google the error for VS 2008 you will find other solutions ranging from deleting registry keys to increasing your memory page size. Moving the project to a new folder is also a suggested fix and is the easiest thing to try first.
