Microsoft Visual Basic Constants

Filter Function

       

Description

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

Syntax

Filter(sourcesrray, match[, include[, compare]])

The Filter function syntax has these named argument:

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

Settings

The compare argument can have the following values:

Constant Value Description
vbUseCompareOption –1 Performs a comparison using the setting of the Option Compare statement.
vbBinaryCompare  0 Performs a binary comparison.
vbTextCompare  1 Performs a textual comparison.
vbDatabaseCompare  2 Microsoft Access only. Performs a comparison based on information in your database.

Remarks

If no matches of match are found within sourcearray, Filter returns an empty array. An error occurs if sourcearray 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.
