Remarks

COM Signature

From textmgr.idl:

HRESULT IVsTextView::GetScrollInfo(  
   [in] long iBar,  
   [out] long *piMinUnit,  
   [out] long *piMaxUnit,  
   [out] long *piVisibleUnits,  
   [out] long *piFirstVisibleUnit  
);

The piFirstVisibleUnit and piVisibleUnits parameters define the visible range in the view. For example, if lines 10 through 25 were visible in the view, then piFirstVisibleUnit would have a value of 10 and piVisibleUnits would have a value of 15.

Note

Scroll bar information is not guaranteed to directly match line information. The values returned are based on the core text editor settings.
