String Functions

This tutorial will teach you all of the basic string functions available in ASP using VBScript. I will keep things concise as possible. The following is a list of the functions and an example of each.

Asc();

Asc() will provide you with the ASCII character code of the character in the parentheses.

<%
str1 = Asc("B")
response.write str1
%>

cStr();

cSrt() will convert a numeric value into a string.

<%
int1 = 35
str1 = cStr(int1)
%>

inStr();

inStr() will locate the occurance of a character (or set of characters) in a string and output it's place.

<%
str1 = "ABCDEF"
str2 = inStr(str1,"BC")
response.write str2
%>

LCase();

LCase() will convert an entire string to lowercase.

<%
str1 = "ABCDEF"
str2 = LCase(str1)
response.write str2
%>

UCase();

UCase() will convert an entire string to uppercase.

<%
str1 = "abcdef"
str2 = UCase(str1)
response.write str2
%>

Trim();

Trim will remove all blank spaces from the beginning or end of a string.

<%
str1 = " ABCDEF"
str2 = Trim(str1)
response.write str2
%>

Len();

Len() will tell you the number of characters in a string.

<%
str1 = "ABCDEF"
str2 = Len(str1)
response.write str2
%>

Replace();

Replace() will replace a character (or set of characters) with another character (or set of characters).

<%
str1 = "ABCDEF"
str2 = Replace(str1,"CD","YZ")
response.write str2
%>

Split();

Split() will split a string into an array of values based on the character defined.

<%
str1 = "ABC,DEF"
str2 = Split(str1,",")
response.write str2(0)
response.write "
"response.write str2(1)
%>

Left();

Left() will retrieve the number of characters specified from the left of the string.

<%
str1 = "ABCDEF"
str2 = Left(str1,3)
response.write str2
%>

Right();

Right() will retrieve the number of characters specified from the right of the string.

<%
str1 = "ABCDEF"
str2 = Right(str1,3)
response.write str2
%>

Mid();

Mid() will retrieve the number of characters specified from the middle of the string.

<%
str1 = "ABCDEF"
str2 = Mid(str1,3,2)
response.write str2
%>

That's it! Have fun playing with strings.
