what did you mean by login file stored online?
look, the scripts i have provide here can be applicable on offline textfiles only. if you wish to try to access from an online source then the programming technique is completely different.
now the access technique depends on the type of connectivity you are using. if you use a local area connection network then your login.txt file must be placed into a server and all client nodes must have sufficient priviledge to access the server.
now if you wish to access this file from a remote server such as a webserver you must write an asp script for that. simply writing code from your vb6 application to connect to the text file won't work.
infact, in such a case textfiles are useless. using databases is always preferable in this context.
and one more thing,
all scripts that i provided here are 100% correct and running smoothly. they are all tested. now if any one of these failes to run on your machine that doesn't mean that the code is wrong. you should have to modify the code to suit your program. if its possible for you upload your existing application here so that i can check it on my machine.
by the way, i have checked the link you provided. sorry to say but its a broken link.
now the decision completely depends upto you. but you must not blame on code/scripts submitted …
