>I have an application in VFP 6.0 that gets a list of all the printers from the registry. This uses the Registry.Vcx that ships with VFP 6.0. I then present all the printers in a list box for the user to select. After the user selects the desired printer, I then write the selection back to the registry and also write the selection to the device key in the win.ini file (About the 4th line down).

You might want to investigate the DEFPRINT.ZIP utility I mentioned a few days ago from www.ntfaq.com; it is a utility that will correctly assign the default printer for Windows that works from the command line, and the C code for it would provide a correct template for performing the necessary manipulations for you.
