Use this method to convert a text stream position to a line and column index. To convert a line and column index to a text stream position, use GetNearestPosition. The GetNearestPosition method accounts for virtual space in the view and provides the position of the end-of-line (EOL) marker on the given line if the column is in virtual space or at the end. Virtual space is space that shows in the view but if not part of the text buffer. The virtual space setting is access from Tools\Options\Text Editor\All Languages\General. For more information, see General, All Languages, Text Editor, Options Dialog Box.
