    username and password in a data file??? which kind of security is that?

    To write two strings in a binary file:

    Code:
        Dim f As Integer
        f = FreeFile
        
        Open "c:\s.dat" For Binary Access Write As f
        Dim u As Variant
        Dim p As Variant
        u = "My user account"
        p = "My password"
        Put f, , u
        Put f, , p
        Close f
    and to read them:

    Code:
        Open "c:\s.dat" For Binary Access Read As f
        Get f, , u
        Get f, , p
        Close f
    The strings must be in a Variant so VB knows how to convert them from the file.
    But careful: anyone can open the file in notepad and read them!
