I'm working on a vb express 2010 project. I noticed that in the project, there is a file base.vb. It is a blank file. Obviously, I did not add it to the project and I'm the only one who access this pc. so, I guess vb express added it.

and I deleted it, and seems the project still works fine.

what is it for? anyone knows? I inhert some class from COM, is it because of this?

I tried search the answer, but can not find one.

thanks
