Inserts a thumb to the collection at the specified index location on the object.
[ lInsertThumb = ] Object.InsertThumb ( vThumb )
The InsertThumb method syntax has the following parts:
| Name | Type | Description | 
| Object | ASlider | ASlider control | 
| vThumb | Val Variant | An integer specifying the index of the thumb on the object. | 
| lInsertThumb | Long | The returned index. | 
The index is zero-based. If the index is out of the range, adds the thumb to the end of the collection.
The following example will insert a thumb to an ASlider control before the 1st thumb:
sld1.InsertThumb(0)
