Add ActiveX Tabs to FeatureManager Design Tree (VBA)

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

'----------------------------------------------------------
' Preconditions:
' 1. In the IDE:
'    a. Insert Microsoft Calendar Control 2007
'       (click Insert > Components > Microsoft Calendar
'       Control 2007).
'    b. Reference Microsoft Calendar Control 2007's ActiveX
'       control file (click Tools > References > Browse button,
'       browse to c:\Program Files\Microsoft Office\Office12,
'       and select MSCAL.OCX).
' 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.
