Add ActiveX Tabs to Model View (C#)

This example shows how to add two ActiveX tabs to a model view.

//----------------------------------------------------------
// Preconditions:
// 1. In the IDE:
//    a. Reference Microsoft Calendar Control's ActiveX
//       control file (click Project > Add Reference >
//       Browse tab).
//    b. Browse to:
//       c:\Program Files\Microsoft Office\Office12\MSCAL.OCX
//       and click OK.
//    c. Reference Microsoft.VisualBasic namespace (click Project >
//       Add Reference > Microsoft.VisualBasic).
// 2. Specified part document exists.
//
// Postconditions:
// 1. Two new tabs are added to the model view.
// 2. New tabs have Microsoft Calendar Controls,
//    Calendar 1 and Calendar 2.
// 3. Model view is active.
// 4. To verify the ActiveX controls on the new tabs,
//    interactively click each Calendar tab.
//
// NOTE: Because the part document is used elsewhere,
// do not save any changes when closing it.
