Hi, Does anyone know if there's something I have to do (or avoid doing) to make my game minimise when the player hits Alt+Tab whilst running in fullscreen with no other apps running? My game isn't minimising in pre-Vista versions of Windows, but other games seem to do so. Windows isn't sending me any WM_ACTIVATE or WM_ACTIVATEAPP messages. I am getting WM_NCACTIVATE and WM_CANCELMODE, and I'm passing these on to the default WndProc expecting it to handle any necessary plumbing. With other apps running the Alt+Tab behaviour is correct in fullscreen, but in this case Windows is sending me a completely different sequence of messages. Thanks in advance, Oscar Cooper Lead Programmer Frontier Developments Ltd |

Hi Oscar,
IIRC, we've always been doing something like
if( (msg.message==WM_ACTIVATE && (LOWORD(msg.wParam)==WA_INACTIVE || HIWORD(msg.wParam)))
|| msg.message==WM_CANCELMODE
|| msg.message==WM_KILLFOCUS
|| (msg.message==WM_ACTIVATEAPP && !msg.wParam)) {
if (bInFullScreen) {
PostMessage(NULL, WM_SYSCOMMAND, SC_MINIMIZE, 0);
}
That seems to work for us, YMMV.
HTH,
Alen

I still haven't got this working, testing under WinXP :-(
Alen's idea gets me most of the way there, but my window gets restored
immediately after being minimised. Looking through the windows message
trace, it looks like the minimise completes successfully: the WM_SYSCOMMAND
triggers a bunch of further messages including the WM_ACTIVATE (WA_INACTIVE)
and WM_ACTIVATEAPP (wParam=FALSE). However I then immediately get a
WM_ACTIVATE (WA_ACTIVE) message, which I assume is generated by Windows in
response to certain properties of my window or because I'm not handling some
messages correctly.
In addition to Alen's code I've also tried experimenting with the window
style flags, and even tried calling SetWindowPos to force my window first to
the bottom of the z-order and then again to put it back on top, to make sure
it's not TOPMOST, but I'm still missing something.
I hate working with API's I don't know very well, I feel like such a n00b
;->
Can anyone bail me out?
Cheers,
Oscar.

Replying to my own post...
I eventually got it working by recording the HWND passed with the
WM_CANCELMODE message, then next time around my game loop calling
ShowWindow( hWnd, SW_MINIMIZE ). This may not be the ideal solution to the
problem so I'd still be interested in hearing if there's a better way.
Thanks to all who helped,
Oscar.

Are you resetting display mode when you receive WM_SYSCOMMAND,SC_MINIMIZE?
Also one trick more... in some apps I think I used to set a bool
when receiveing a window resize/minimize/maximize command and then
just eat all window size related messages without processing them
until we empty the queue (no more messages pending). This kills all
quirks that Windows throw on you as sideeffects of changing a window
size.

I'm letting the default wndproc handle that message, my actual display is
managed with D3D and uses the DEVICELOST error codes to trigger resets
without touching the Win32 API.

There are also a number of other elements that could affect your game's alt-tab response: - Window Style and Window StyleEx flags (during create/adjust window) - SetWindowPos parameters - Use of SetForegroundWindow() and LockSetForegroundWindow() calls Also, alt-tab settings can differ not only in different OSes (2000 vs XP vs Vista) but also different service packs (especially of XP). And there's also some registry OS tweaks that change response and how 'sticky' the topmost window is. Microsoft seems to perpetually adjust this as new apps find new ways to 'steal' focus and need to be dealt with. (Interestingly, some of the most notorious 'stealing' apps are made by Microsoft themselves, such as their outlook and MSN 'notifications' etc). The moral of the story is to test on as many different systems as possible, including multi-mon combinations as well. -- George. - Lead Programmer, BattleGoat Studios - www.battlegoat.com -----Original Message----- From: gam...@li...

Subject: [GD-Windows] Alt+Tab in fullscreen with no other apps running Hi, Does anyone know if there's something I have to do (or avoid doing) to make my game minimise when the player hits Alt+Tab whilst running in fullscreen with no other apps running? My game isn't minimising in pre-Vista versions of Windows, but other games seem to do so. Windows isn't sending me any WM_ACTIVATE or WM_ACTIVATEAPP messages. I am getting WM_NCACTIVATE and WM_CANCELMODE, and I'm passing these on to the default WndProc expecting it to handle any necessary plumbing. With other apps running the Alt+Tab behaviour is correct in fullscreen, but in this case Windows is sending me a completely different sequence of messages.
