Bitmap-Handle
This property identifies the bitmap strip handle to be used in the Tab identified by the Tab-Index property.
When values are enclosed between parentheses, the Tab-Index property is ignored, the 1st value refers to the 1st Tab, the 2nd value refers to the 2nd Tab and so on.
If this property points to an animated GIF, then the tab renders the animation.
