If I am running fullscreen, is it ever a bad idea to...

... make the window be 0 pixels across, and 0 pixels down? It works for me (with XP), but I don''t know if it wouldn''t work with a different Windows version, or maybe it wouldn''t work for some other reason. Is there any reason not to do this?

Well, I just Alt+Tab, read the Debug messages, and Alt+Tab back.

When you Alt+Tab out you lose your device, so if you step through code in the debugger many calls will fail that normally wouldn''t. Being able to see debug messages while things are running can also be a huge help.

Honestly, making it so you can start in windowed or fullscreen is VERY easy. If you check out my tutorials they all pop up a message box to prompt for fullscreen or windowed and all the code is there (there isn''t a lot involved) to handle both modes. The code is free to use and doesn''t use any frameworks so you can just drop it in to your code with minimal effort.

I correctly handle lost devices though.

But I will add windowed functionality to my engine, after I finish the rest of it. Right now it is set up for fullscreen mode.

The hardest part will be dealing with the damn WndProc...

I don''t see what the problem is for making windowed or fullscreen mode. It''s simple!

//D3D9 is what I''m showing herevoid InitD3D(bool WindowedMode){D3DPRESENT_PARAMETERS d3dParams;d3dParams.Windowed = WindowedMode;//rest of initialization code}

That''s the only place I ever have to specify wether it''s windowed or not. Of course there are other places where I check, but that''s because of features I can only use in fullscreen mode (multiple monitors) or problems that only occur in fullscreen mode (losing devices).

The only thing that I''m not sure if you have to do differently is that you have to specify the window on your CreateDevice call. I don''t know if it''s required in Fullscreen mode, but it works fine.

Sure, but you can only recover the device when you alt-tab back in to the app, and likely only at the end of your render loop. This makes it impossible to step through code in the middle of your render loop.

What''s the difficulty with WndProc?

Additionally you should check back buffer formats differently and probably create the window differently as well. But it is really easy to do.

And yes, even in fullscreen you still need the window.

True, allow users to choose from a list of supported backgrounds in fullscreen mode, but in windowed mode you have to stick them to their windows desktop. That''s on my todo list, right now I just stick them to their desktop, which works fine for debugging and doesn''t require a switch between windowed and fullscreen mode.
