We can compare two strings by using built in ASP function StrComp(). We can also specify different way of comparison by adding a third optional value in comparison. Here is the syntax of StrComp function.
StrComp(string1, string2, comparetype )
string1 and string2 are two string variables we are comparing, the value of comparetype ( Optional ) can be either 1 or 0. By default it is set to 0. If comparetype is set to 1 then lower case and upper case text are treated as same. If comparetype is set to 0 then ( or not entered ) then binary comparison is done so upper case letters comes before the lower case letter.
The output of the StrComp function gives output 0 if both the compared strings are equal and gives -1 if string1 is less than string2. It gives output 1 if string1 is greater than string2.
Here is the code for StrComp function comparing two strings.
Dim string1,string2
string1="Plus2net.com"
string2="plus2net.com"
Response.Write StrComp(string1,string2,0)
For different values of string1 and string2 with two values of comparetype the output we will get is given here in a table.
