Remarks

COM Signature

From textmgr.idl:

HRESULT IVsTextBuffer::GetLastLineIndex(
   [out] long *piLine,
   [out] long *piIndex
);

This method might require considerable resources, depending upon the underlying implementation of the buffer. That is, it might be very difficult to calculate the size of the buffer if it is a virtual-line-oriented implementation as in Visual Basic.
