FUNCTION: StrComp( )

StrComp(String1, String2, Compare)

The StrComp function compares two strings to see if they are the same. You can have the comparison be sensitive, or not, to the case (upper versus lower) of the characters in the two strings. The default is to be case sensitive (binary comparison).

If the strings are the same, the output is zero. If the strings are different, the output will be a 1 or -1 depending on the order of the strings.

There are two mandatory arguments.

String1

The String1 argument is the first of two strings to compare.

String2

The String2 argument is the second of two strings to compare.

Code:
<% =StrComp("Mountains of the Moon", "Mountains of the Moon") %>

Output:
0

Code:
<% =StrComp("Mountains of the Moon", "Red sails at sunset") %>

Output:
-1

There is one optional argument.

Compare

The optional Compare argument can be used to set whether the comparison is case sensitive (upper versus lower), or not. You must only use the constant or the value of the COMPARISON CONSTANTS.

CONSTANT	VALUE	DESCRIPTION
VBBinaryCompare	0	Binary comparison (case sensitive)
VBTextCompare	1	Text Comparison (case insensitive)

Code:
<% =StrComp("Mountains of the Moon", "mountains of the moon", 0) %>

Output:
-1

Code:
<% =StrComp("Mountains of the Moon", "mountains of the moon", 1) %>

Output:
0

Code:
<% =StrComp("RED", "red", VBTextCompare) %>

Output:
