Mid() and Asc() functions in ASP pages... where have they gone...

[Craig Humphrey]

Hi,
either I'm doing something fundamentally wrong, or Mid() and Asc() are not
available in ASP pages.

I was building a function to work through a string and return the Ascii
equivalent (inline):

function convertString(strText)
Dim intI, strFake, chrThis, intThis, strThem
strFake = ""
chrThis = ""
For intI = 0 To len(strText) -1
chrThis = Mid(strText, intI, 1)
intThis = Asc(chrThis)
strThem = CStr(intThis)
strFake = strFake & chrThis & "[" & strThem & "]"
Next
convertString = strFake
end function

but I get the classic:
Microsoft VBScript runtime error '800a0005'
Invalid procedure call or argument: 'Mid'

error from the server.

The server is a vanilla NT4SP5 using IIS4. I have no idea what IIS service
packs have been applied, though I'm about to work through all the security
patches I can find...

Any clues people?

Later'ish
Craig

Hi!
The loop in your code is wrong. You have to start to count from 1 and not 0.
The Mid function can not take 0 as the second parameter. The 'start'
(second) parameter starts with 1 and not 0.

Craig,

VBScript indexes strings from 1, not zero, so

Mid( <String>, 0, 1 )

might upset it a little.
Change the loop to

For intI = 1 To Len(strText)

HTH,
