: Can anyone help me.
: I want to compile one VB Project from another VB Project.
: Is this in anyway possible.
: If yes, How?

Check out MSDN website for more, but I'm pretty sure that there are a few command line switches ("/make", perhaps? I can't remember), so that calling "vb6.exe C:\programDir\project.vbp /make", instead of opening the IDE with the selected project, the exe will compile it. Of course this requires a copy of VB6 to be installed.
