using VB .NET set up

Question

I am just starting out with using the .NET development to do VB development. How are projects developed under the previous version opened with the VB .NET development environment? It seems all I have to build the project with is the .vbp or the .vbw but when I try to open these files in the .NET IDE and it doesn't seem to work at all. I looked at the [b]About[/b] window of my .NET IDE and it seems I have C ++ .NET installed but not VB. At work the collection of installation discs I have includes two yellow Visual C++ .net disks and 3 light blue MSDN LIBRARY disks and a Visual Studio Prerequisite disc. The box that everything comes in is Microsoft C++ .net standard. I guess there is a whole other product I need to buy (or have my boss buy)? Didn't 6.0 include everything -- both C++ and VB?
