Random file access problrm

[Slurpee]

I'm new to the random file thing and I'm having a few issues trying to make a simple lotto number generator/analyser. Anyway I'm generating the six random numbers and then sticking this info into an array so I can check for duplicates. Naturally this is the easy bit, I fall into problems when I try and enter this info into my file structure. So anyone got some advice on looping and entering random information into a file structure???

 

I have done it this way to start the project off:

FileOpen(1, "numbers.data", OpenMode.Random, OpenAccess.ReadWrite, OpenShare.Shared, Len(udtLotto))

       For count = 1 To 10
           udtLotto.first = ran()
           udtLotto.second = ran()
          etc...

           FilePut(1, udtLotto, count)
        Next count
        FileClose(1)

any advice warmy appreciated :)

I would recomend dropping the VB6 FileOpen / FilePut and look at the System.IO namespace.
