user32: Handle WM_ENDSESSION in DefWinProc(). DefWinProc() should call PostQuitMessage() on WM_ENDSESSION if the shutdown is proceeding.
Hi Francois, This patch is causing a problem in Pegasus Mail. Closing some dialogs cause termination of the complete program. Here is a part of SPY++ log when run under win2000, when I close the edit new mail dialog: |<00202> 00130A82 S ..........................WM_SYSCOMMAND uCmdType:SC_CLOSE xPos:672 yPos:121 [wParam:0000F060 lParam:007902A0] |<00203> 00130A82 S ...........................WM_CLOSE wParam:00000000 lParam:00000000 |<00204> 00130A82 S ............................WM_QUERYENDSESSION nSource:1 (End Task from Task List dialog) [wParam:00000001 lParam:00000000] |<00951> 00130A82 R ............................WM_QUERYENDSESSION fShutdownIsOk:True [lResult:00000001] ... |<00952> 00130A82 S ............................WM_ENDSESSION fEndSession:True [wParam:00000001 lParam:00000000] |<00953> 00130A82 R ............................WM_ENDSESSION lResult:00000000 The WM_QUERYENDSESSION and WM_ENDSESSION are sent by the program: |0009:Call user32.SendMessageA(00030024,00000011,00000001,00000000) ret=0040641d How did you check the behavior of the Windows DefWindowProc? If I put a DefWindowProc(hwnd, WM_ENDSESSION, 1, 0); some where in a windows program nothing happens, while a PostQuitMesage certainly closes the app. Rein.

The WM_QUERYENDSESSION and WM_ENDSESSION are sent by the program:
|0009:Call user32.SendMessageA(00030024,00000011,00000001,00000000) ret=0040641d
It's pretty weird that the application is sending a WM_QUERYENDSESSION/WM_ENDSESSION to itself.
How did you check the behavior of the Windows DefWindowProc? If I put a DefWindowProc(hwnd, WM_ENDSESSION, 1, 0); some where in a windows program nothing happens, while a PostQuitMesage certainly closes the app.
I used a modified poppad sample app from Petzold and used Spy++ to check that a WM_ENDSESSION caused the app to exit eventhough that application's main loop did not contain any special handling for WM_ENDSESSION. So, since the decision to exit on WM_ENDSESSION is not made in the application's main loop I placed it in the DefWindowProc. But I must have gotten some detail wrong. Unfortunately I'm away from my computer for the next week, so I can't investigate right now. -- Francois Gouget fgouget(a)codeweavers.com

I see that this is still a problem in 0.9.10 so I've fallen back again to 0.9.8. -- Jim
Pardon intrusion by this Wine user into this technical discussion. Is the problem with Pegasus Mail (PM) that is mentioned below something that is new with Wine 0.9.9? I know that I saw termination of "the complete program" whenever I sent a message using PM 4.31 and Wine 0.9.9. As a result I've reverted to Wine 0.9.8 and have none of this. -- Jim Rein Klazes wrote at 15:20 on 11 Mar 2006:

You do not even have to send the message, just closing the compose new message window is enough. Yes, it is new in 0.9.9. Rein.
