I am writing a condition to determine if a letter in a string is alphanumeric. It seems to be failing.

If Mid(strNew, i, 1) Like ("[A-Z]") Or Mid(strNew, i, 1) Like ("[a-z]") Or Mid(strNew, i, 1) Like ("#") Then

I keep falling into this condition even if the character is "[" or "("

This doesnt seem to be working. Is this the wrong syntax for find alpha numerics in classic ASP?

i'm curious as the purpose of this....

it seems like you may want to tryout Regular Expressions for this...something like

set objRegExp = New RegExp
objRegExp.Pattern = "^([a-zA-Z0-9])"
objRegExp.Test(variable) 'for a boolean value
set objRegExp = nothing

How about

If asc(Mid(strNew, i, 1) ) > 65 or  asc(Mid(strNew, i, 1) )< 127 Then

This seems to work beautifully. thanks.

elseif objRegExp.Test(Mid(strNew, i, 1)) = true then

I am parsing through a string(from a textbox a user puts in search strings) and inserting wildcard symbols to words for an oracle query.
