validating the string in ASP

P: n/a

Hi! i m new to this forum and need some help in ASP

how can i validate a string so that it have only the characters
of ASCII 32 to 91 and 93 to 122 ? Also if the string contains the
comma (,) the whole string should be converted inside the quotes ("")
i.e.

if the string is: example string, Ok
it should be: "example string, Ok"

On the server side, use VBScript Regular Expressions:

On the client side, use the Javascript version:

Why this serversie preoccupation with vbscript?

Jscript regex is cleaner code.

Ermm... because I don't know Jscript? And I don't think I'm alone in
that among ASP coders. And anyway - VBScript does the job:

<%
dim i, strSearchOn, objRegExpr, objmatch, colmatches
i = 0
strSearchOn = "My Example String"
if instr(strSearchOn,",") then strSearchOn = """" & strSearchOn & """"
Set objRegExpr = new regexp
objRegExpr.Pattern = "[^\40-\133\135-\172]"
objRegExpr.Global = True
objRegExpr.IgnoreCase = True
set colmatches = objRegExpr.Execute(strSearchOn)
for each objmatch in colmatches
if objmatch.value <> "" then
i = i + 1
End If
next
If i > 0 then
response.write "Validation Failed"
Else
response.write "Validation Passed"
End If
%>

If you mean by "cleaner code" there's less of it, that's true. But the
time taken to produce the above in VBScript was considerably less than
learning JScript just for use with RegEx, which seems to me to be a
huge investment in time for little gain - purely from my point of view
:-)

How does the above deal with illegal characters such as ~ \ { } | ?

Illegal in what sense?

They are perfectly legal under Netherlands jurisdiction. ;-)

Externally to the jscript part,
the function acts like a vbscript function.

Anyway, you can try, by putting the above script in an asp file.

There's an awful lot that's legal in the Netherlands that isn't
anywhere else :-P

In this case, however, I meant the characters deemed illegal in the OP.
Only strings that did not contain those characters (and some others)
were allowed - althought the OP didn't say what they wanted to do if
the string contained those characters....

Externally to the jscript part,
the function acts like a vbscript function.

Anyway, you can try, by putting the above script in an asp file.


I did try it. All it seemed to do was put quotes round strings
containing commas. It didn't seem to do anything with characters
outside the ascii range the OP wanted to avoid. Maybe I'm missing
something here?

I took that as having them deleted, as the output was not to be a
true/false, but a corrected string.

True, but see my "taking" above.

32-91 -> space-[
and
93-122 -> ]-z

s = s.replace(/[^ -\[\]-z]/,'')

they are replaced by an empty string, as I showed with the
vbCr = chr(13) example.

for testing purposes you could do:

s = s.replace(/[^ -\[\]-z]/,'?')

which would replace them with a "?".
