CompareMode Property

Sets and returns the comparison mode for comparing string keys in a Dictionary object.

object.CompareMode[ = compare]


Required. Always the name of a Dictionary object.
Optional. If provided, compare is a value representing the comparison mode. Acceptable values are 0 (Binary), 1 (Text), 2 (Database). Values greater than 2 can be used to refer to comparisons using specific Locale IDs (LCID).


An error occurs if you try to change the comparison mode of a Dictionary object that already contains data.

The following example illustrates the use of the CompareMode property:

[JScript]function TestCompareMode(key)
   // Create some variables.
   var a, d; 
   var BinaryCompare = 0, TextCompare = 1;
   d = new ActiveXObject("Scripting.Dictionary");
   // Set Compare mode to Text.
   d.CompareMode = TextCompare;
   // Add some keys and items.
   d.Add("a", "Athens"); 
   d.Add("b", "Belgrade");
   d.Add("c", "Cairo");
Dim d
Set d = CreateObject("Scripting.Dictionary")

d.CompareMode = vbTextCompare
d.Add "a", "Athens"   ' Add some keys and items.
d.Add "b", "Belgrade"
d.Add "c", "Cairo"
d.Add "B", "Baltimore"   ' Add method fails on this line because the 
                         ' letter b already exists in the Dictionary.
