server side username and password validation?

Hi again,

I am making an internet application,

commands between the server and client are numbered so the server knows what to do with the information being received.

example

CLIENT: Hello server, my username is vwiley2001
would be sent to the server like this:
102 vwiley2001

SERVER: Hello vwiley2001, go ahead with your password, would be sent to the client like this:
110 vwiley2001

CLIENT: Hello server, my password is "something"
would be sent to the server like this
115 something

Right now the servers response to the password is, who the heck are you?

I need to find a way to let the server know that
winsock(5) is vwiley2001
or winsock(2) is compguy121

so when winsock(5) sends back "115 something" the server knows to check vwiley2001's password to the password that is stored on the server for that username.

Any idea's would be more than helpful!!!

Hi,

I figured it out. Here's what I am doing.....

when I send a command from the client to the server there is 3 parts to it.

First the command
Then the username which it come from
then the message or password

example

winsock.senddata "110" & "~" & combo1 & "~" & txtPass.txt


Now when the server receives a command it parses it and seperates the 3 different parts of the data.

That allows me to check the command which in this case is 110 (which stands for user validation)

then it allows me to check if the password supplied for that username is valid.

I've implented the function above on the client side to so it knows what to do with information received from the server.
