Arrgh. Well, I did say it was a quick glance. :-) I saw the Hungarian notation "h" and figured it was just your average old integer. At closer examination, these will be the two sticking points. The two pointers to a callback procedure should be able to be safely set to NULL (after setting the appropriate flags in the Flags param). The same goes for hInstance. As for DEVMODE and DEVNAMES, I believe Ed Rauh's CLSHEAP should do the trick. (DEVMODE sure looks nasty, though.) Unfortunately, I'm way too busy today to hammer out the sample code (new testing toys, woo hoo!).
