Hmmm, haven't been in this forum in a while. Hey! Why doesn't my forum have a water cooler and pinball? [oh] Anyway. I'm trying to make a program that runs fullscreen on WinXP's second monitor. The program I'm making uses OpenGL heavily, so the window initialization for the styles and such is borrowed heavily from NeHe's basecode. Now, the fullscreen works and all, but only on the primary screen. If I try to fullscreen it on monitor 2, it jumps back to monitor one. I can't give a tremendous number of details on how this did and didn't work, since the computer I do this on I only see every few days as I write the program from home, and I don't have a second monitor here to test with. But does anyone just happen to know what window style or class I should/shouldn't be using to make this possible?

You've got to force your program to the pixel dimensions of the other monitor. OpenGL should follow...

It'll explain it better than I can...

That looks most promising; thank you.

Aw, snaps. [crying]

Like I said, this is OpenGL. Is that info still current? Because that's kinda a kick in the nuts if it is; nothing against DirectX, but I don't feel like learning a whole new API to do this.

Well, the linked website mentions DirectX 8, which is at least three years old. I don't think much would have changed since then, though.

Have you tried a "fake" fullscreen window? That is, make a topmost border-less (WS_POPUP, I think) window that is the size of the display, and keep it on the desktop of the second monitor. It might have better support than a real fullscreen app..

I actually had, but ran into trouble with positioning and dropped it since it seemed a clumsy hack. Now I see a clumsy hack is what's called for, so I guess I'm stuck. [smile] I guess I use the information here to determine where upper-left on the second monitor is and slap a window there. Sound like a plan?

I'm not sure whether this will affect your application or not, but any 'accelerated' application (that is, 3D apps, ones that use hardware overlays and so on) I run on one monitor then move to the other runs incredibly slowly, and only work properly if they recreate the device on the secondary monitor.
