Add ActiveX Tab to FeatureManager Design Tree Example (C#)

This example shows how to add a tab to the FeatureManager design tree using three on-disk bitmap files for the tab's scaleable icon.

//----------------------------------------------------------
// Preconditions:
// 1. In the IDE, reference your ActiveX control file 
//    a. Click Project > Add > Reference > Browse.
//    b. Browse to c:\Program Files\SOLIDWORKS Corp\SOLIDWORKS\SldUtils.
//    c. Select RichEditCtrl.ocx.
//    d. Click OK.
// 2. Verify that the specified part document exists.
// 3. Modify the namespace to match your project name.
// 4. Modify bitmapnames to reference your icon bitmaps in three sizes.
// 5. Review the ActiveX control reference and ensure that ctrlBtm is correct.
// 6. Search for RichEditCtrl.ocx in the registry and ensure that the second
//    argument to CreateFeatureMgrControl4 is correct.
//
// Postconditions:
// 1. Opens the part document and adds a new tab to the 
//    FeatureManager design tree with an icon that uses the bitmap size 
//    that fits the screen resolution.
//    NOTE: To add a tab to the FeatureManager tree,
//    you must set IModelViewManager::CreateFeatureMgrControl2's
//    WhichPane parameter to swFeatMgrPane_e.swFeatMgrPaneBottom.
// 2. Activates the new tab.
//
// NOTE: Because the part document is used elsewhere,
// do not save changes.
