Add ActiveX Tabs to FeatureManager Design Tree (C#)

This example shows how to add tabs to a split FeatureManager design tree, using an on-disk bitmap file for the tabs' icons.

// Preconditions:
// 1. In the IDE:
//    a. Reference Microsoft Calendar Control's ActiveX
//       control file (click Project > Add Reference >
//       Browse
//    b. Browse to:
//       c:\Program Files\Microsoft Office\Office12\MSCAL.OCX
//       and click OK.
// 2. Specified part document and bitmap exist.
// Postconditions:
// 1. The FeatureManager design tree is split.
// 2. A new tab is added to each FeatureManager design tree;
//    the top Microsoft Calendar Control's background is black
//    and the bottom Microsoft Calendar Control's background
//    is red.
// 3. The new tab on the top FeatureManager design tree
//    is active.
// NOTE: Because the part document is used elsewhere,
// do not save any changes when closing it.
