Loops through each project in your solution and lists the GUID of each ActiveX (COM) control.

' Add a reference to Microsoft.VisualStudio.VCProjectEngine and have a 
' Visual C++ .NET project loaded before running this example. Also, you 
' should have at least one ActiveX (COM) reference in a project.
