Split FeatureManager Design Tree and Position Splitter Example (C#)

//----------------------------------------------------------
// Preconditions:
// 1. In the IDE, reference your ActiveX control file
//    (click Project > Add Reference > Browse and browse
//    to the folder where the ActiveX control resides and click
//    the ActiveX control file > OK).
// 2. Verify that the specified part document and bitmap exist.
// 3. Replace activex_control_component_declaration and
//    activex_control_CLSID_or_ProgID with your ActiveX control's
//    information.
//
// Postconditions:
// 1. Opens the part document and splits the FeatureManager
//    design tree; the splitter is below the FeatureManager
//    design tree to which the tab was added. Drag the splitter
//    to verify.
// 2. Close the part document.
// 3. Set test to 1.
// 4. Rerun the macro.
// 5. Opens the part document and splits the FeatureManager
//    design tree; the splitter is above the FeatureManager
//    design tree to which the tab was added. Drag the
//    splitter to verify.
//
// NOTE: Because the part document is used elsewhere,
// do not save changes.
