Returns the horizontal insertion position of a text in this object. This position is measured in Himetric units, in which each unit is equal to 0,0001 of a meter. Users can use either this property or the CurX property to move the insertion point in a text as users move over this object's content. When users move the insertion point to another row in a text, this property specifies the best position for text's insertion point. The CurX property is defined in this value if text row is greater than the value of this property. Otherwise, the CurX property is defined at the end of text's row. This is a read-only property.
