CMarkup GetElemIndex Method
int CMarkup::GetElemIndex() const;
GetElemIndex returns the current main position element's internal index. If there is no current main position, it returns
0. See ElemIndex Navigation for the full story on all the ElemIndex methods.
The ElemIndex functions provide access to the internal element indexing of CMarkup. Do not attempt to goto an index of an element that may have been deleted. Also, indexes are only valid during the course of the CMarkup object's lifespan unless it is re-initialized (with SetDoc or Load). As elements are added and removed to a CMarkup object, an existing element's index remains valid unless it is removed or replaced.
