ok, .. Thx..
Even if I was not sure of it.. I actually knew that when I create a new project in vb.net, the files created were .vbproj (for the project) & .sln (solution).. something like that.
It is just that this question seemed a bit vague to me. Was it referring to the vb.net project files, or maybe when you create some text file via vb.net..
