Okay, maybe you all know this already, but every once and awhile someone asks a question about dual monitor debugging and NO ONE answers it! Anyhow, here''s how I did it and it''s really simple. OS: Win2K HARDWARE: 2 video cards (I use g400 + 8mb PCI [SiS chipset]) COMPILER: VC Toss in the two cards and make sure windows recognizes them both. Go into display properties (control panel), select the second video card (just click on monitor #2) and check the "extend my window desktop onto this monitor". Now go to the DX control panel icon and go to directdraw-> advanced properties. Check the option that reads "enable multi-monitor debugging". You might want to boost up the Debug Level slider to "more". Run compiler. When you start debugging, your application will run on the primary (they say secondary, but mine runs on the primary) display while the debugger on the secondary. It''s soo amaazing! Anyhow, I bet you can do this with other compilers and win98 too.. but the above is what I use. I hope this helps people! PS: you might have to fool around with the jumpers on the second video card... you have to set it so that it''s ''disabled''... or disable INTA. ~Queasy.
