IsInOrder Method

Summary

A helper function for loosely determining whether two DocumentViewerTextPosition objects are in order.

Syntax
C#
VB
C++
Public Shared Function IsInOrder( 
   ByVal minPosition As DocumentViewerTextPosition, 
   ByVal maxPosition As DocumentViewerTextPosition 
) As Boolean 

Parameters

minPosition

The DocumentViewerTextPosition that should be a lower page number and/or character index than maxPosition.

maxPosition

The DocumentViewerTextPosition that should be a higher page number and/or character index than minPosition.

Return Value

true if the minPosition has an explicitly lower page number and/or character index than maxPosition; otherwise, false.

Remarks

IsInOrder indicates whether the two provided DocumentViewerTextPosition are in order from "lowest" to "highest" by PageNumber and then by CharacterIndex. If both page numbers are the same and if maxPosition has a CharacterIndex of -1 (indicating the end of a page), IsInOrder will return true. IsInOrder does not check against the actual last character in any document.

Pseudo-code:

if (minPosition.PageNumber < maxPosition.PageNumber) 
   return true; 
else if (minPosition.PageNumber == maxPosition.PageNumber) 
   return (maxPosition.CharacterIndex == -1) || (minPosition.CharacterIndex != -1 && minPosition.CharacterIndex < maxPosition.CharacterIndex); 
return false;
