VBscript Built-in Functions

Back to Function List

Filter

Gives a zero-based array containing subset of a string array based on a specified filter criteria

Filter( InputStrings, Value[, Include[, Compare]])

The Filter function syntax has these parts:

 

Part Description
InputStrings Required. One-dimensional array of strings to be searched.
Value Required. String to search for.
Include Optional. Boolean value indicating whether to return substrings that include or exclude Value. If Include is True, Filter returns the subset of the array that contains Value as a substring. If Include is False, Filter returns the subset of the array that does not contain Value as a substring.
Compare Optional. Numeric value indicating the kind of string comparison to use. See Settings section for values.
 

The Compare argument can have the following values:

 

Constant Value Description
vbBinaryCompare 0 Perform a binary comparison.
vbTextCompare 1 Perform a textual comparison.
vbDatabaseCompare 2 Perform a comparison based on information contained in the database where the comparison is to be performed.
 

If no matches of Value are found within InputStrings, Filter returns an empty array. An error occurs if InputStrings is Null or is not a one-dimensional array.

The array returned by the Filter function contains only enough elements to contain the number of matched items.
