Beginning of a string.... - Postet den 17 Jan 2009 (1137 Views)

Code:

If InStr(Request.ServerVariables("REMOTE_ADDR"),"41.207") > 0 Then

Is there a way I can make sure this only matches at the beginning of the string?
For example...
Match > 41.207.256.325
Do not match > 256.41.207.325

Thanks!<

If there is a match, the matching position will be returned, so you just need to check the value. If 1, it's the beginning of the string, if greater than 1 you know it wasn't matched at the beginning of the string.<

If InStr(Request.ServerVariables("REMOTE_ADDR"),"41.207") = 1 Then

does the same thing as

if left(Request.ServerVariables("REMOTE_ADDR",6))="41.207" then<

Good to know....
So...

Code:

If InStr(Request.ServerVariables("REMOTE_ADDR"),"41.207") = 1 Then
Go the hell away!
end if

and

Code:

if left(Request.ServerVariables("REMOTE_ADDR",6))="41.207" then
Go the hell away!
end if

Will do the same thing....

Thanks! <
