checking response from readline

hi,

I have the following code which asks user a question and gets response. I
need to check response for validity but the following if statement is always
evaluated as true even when correct response is entered:

wscript.stdout.write "What is the SOURCE file type? (user/computer/group): "
strSourceFileType = trim(ucase(wscript.stdin.readline))
if strSourceFileType <> "user" or strSourceFileType <> "computer" or
strSourceFileType <> "group" then
err.raise 449
ErrHandler
end if

Even when I enter "user" or "computer" or "group" (without quotes) at the
prompt the condition evaluates as true and returns "Microsoft VBScript
runtime error: Argument not optional"

I have witten value of strsourcefiletype to screen and it is populated
correctly with no spaces, etc. as expected by the condition right after it is
read. Now if i simply specify:
if strSourceFileType <> "user" then

without the other two OR conditions and type "user" at the prompt all works
fine. I don't understand why I cannot look for the other values in the field
too. ???

thanks again.

Change ORs to ANDs


Good Luck, Ayush.

'you should use AND instead of OR


wscript.stdout.write "What is the SOURCE file type? (user/computer/group): "
strSourceFileType = Lcase(trim(wscript.stdin.readline))
if strSourceFileType <> "user" and strSourceFileType <> "computer" and
strSourceFileType <> "group" then
err.raise 449
ErrHandler
end if

Hi,

I think so. It should be
if strSourceFileType <> "user" and strSourceFileType <> "computer" and
strSourceFileType <> "group" then

Do you have met any further question? Please feel free to let us know. We
are glad to assist you.

Have a great day.
Sincerely,
Wen Yuan
