How do i create a simple ftp connection with winsock control?

I am trying to create a simple ftp connection that will go out to a server and get a specified file.  But I cant get to the point to enter a username and password.  I want to use the winsock control to do this. When I connect this is what I get:  

connect to "somewhere"
220 "somewhere" FTP server ( version blah blah blah ) ready.

and it stops there.

Plus I would also like to do error trapping, so that if there is an error at all it closes out, and returns an error message as to what happened.

This is simply for getting one ascii file and bringing it back to use.

Thanks

Although it isn't using the winsock control, it still is an in depth detailed answer that gets the job done.

One other question, is this tranferring the file as ascii or binary, because this is a very important part of the program, it needs to be transferred by ascii, or VB doesn't understand the carriage return line feed bytes in the file.  THanks
