Thanks guys,
Yes, SkyIDE supports VB.NET's VBC.EXE but someone requested if I can also add support for VB Express just like I did for VC++ Express. VBC.EXE is installed by the .NET framework as you have already mentioned and I have implemented support for it already. I am not sure if VB Express is using the same one but yes, I will check things out with a process explorer. Thanks for the tip!
