ASP: Regular Expressions

HI,

I need to make a function in ASP and regular expressions that would accept data only in A-Z, a-z, 0-9 only.


Like:

function db(data){

'I need the coding here....

}

Code (markup):

Plz help me


thanx

 

This doesnt use regex but it will filter the characters

function OnlyAZ123(data) as boolean

'heres the characters it can contain
CharsToMatch ="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"
x=0

'assume its ok til we look at the characters
CharsOK=True
for x = 1 to len(data)
'check them one at a time
if instr(CharsToMatch,mid(data,x,1)) = 0 then
CharsOK=False
exit for
end if
next

return CharsOK


end function

 

So, in this list "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"

can I add other characters as well?


Like, CharsToMatch ="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789\^/+_"


or will it not work if i add those special chars??

Thanx
