validating the string in ASP
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" -- asimrafi ------------------------------------------------------------------------ Posted via http://www.codecomments.com ------------------------------------------------------------------------ asimrafi wrote:

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 :-) -- Mike Brind asimrafi wrote on 06 mrt 2006 in microsoft.public.inetserver.asp.general:

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. -- Evertjan. The Netherlands. (Please change the x'es to dots in my emailaddress) Evertjan. wrote:

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.... > I did try it.
