Looping code that i cant seem to work out!

Sorry for the post in this NG but im short on time to get this working
and i haven't seem to of got a response anywhere else.

Im pretty new to asp so all light on this question would be great.

Basically i need to test to see what value is set (where to retrieve the
data from) so ive done it like this:

If Request.Querystring("id") = "" then
TidF=Request.Form("TidF")
Else
TidF=Request.Querystring("id")
End If

The data Request.Form("TidF") comes from a form if submit is pressed.

The data Request.Querystring("id") comes from the url being .asp?id=number

However it seems to keep looping round even though i have ended the if
statement and set the var.

all help would be great thanks.The "If-Else" statement won't cause your code to loop because it's just
a conditional statement. Maybe the behaviour is caused by a different
part of your code? Do you have any "For", "While", "Do...While" or
"For Each" statements?

Thanks for the reply, yes it does contain a loop but the code only seems
to keep looping round since ive added the If statement to get the data.

Here is my code.

thanks agian!
Maybe not the complete answer, but here is a helper.

If Request.Querystring("id") = "" then
TidF=Request.Form("TidF")
Else
TidF=Request.Querystring("id")
End If

if ( Request.Querystring("id") is nothing) then
'' "id" not present, check for TidF
if not (Request.Form("TidF") is nothing) then
TidF=Request.Form("TidF")
else
throw new ArgumentException("Form( TidF ) expected.")
end if

else

if Request.Querystring("id").Length <= 0 then
throw new ArgumentException("Querystring( id) expected.")
end if
TidF=Request.Querystring("id")

end if

Don't check for empty strings as the "exists or not exists". Check for the
object existing or not (null in C# / Nothing in VB.net)
