Termination of application on win9x

[Jammie]

Hi all,

I have a major problem with my application. For some reason on win9x my
application will not exit properly when the user shuts down there system.
This doesnt seem to be a problem on XP. My application in question is a
command prompt based app. For some reason the application does not seem to
recieve its termination signal. Is this a known problem with win9x systems
and if so is there a way to work arround it?

Thanks for any help in advance

You have correctly called "SetConsoleCtrl Handler", or?

See: SetConsoleCtrlH andler
http://msdn.microsoft.com/library/en...trlhandler.asp

Then normaly it should work.

I suppose, that after you receive the End-Event, you do not terminate
correctly...

Set ConsoleCtrlHand ler is set.

The code in question is the following:

BOOL WINAPI ConsoleControlH andler ( DWORD dwCtrlType ){
BOOL bReturnStatus = FALSE;
switch( dwCtrlType ){
case CTRL_C_EVENT:
if(gstate.activ ities_suspended ) {
resume_client() ;
} else {
suspend_client( );
}
bReturnStatus = TRUE;
break;
case CTRL_BREAK_EVEN T:
case CTRL_CLOSE_EVEN T:
case CTRL_SHUTDOWN_E VENT:
quit_client();
bReturnStatus = TRUE;
break;
case CTRL_LOGOFF_EVE NT:
if (!gstate.execut ing_as_daemon) {
quit_client();
}
bReturnStatus = TRUE;
break;
}
return bReturnStatus;
}

When i run the application on windows 98 the above code does not seem to run
when a shutdown or logoff action is taken. Does anyone have any idea's?

I have investigated further, this is to do with a bug in windows 9x where if
multiple messages are sent to the console control at the same time they get
ignored. This means the messages are never recieved by the application. I
dont know waht to do now. Im working on pre ME so im not sure waht my
options are. I am running a separate application that is running as a
windows application, maybe i could authorise the shutdown of the client from
this other program, but if no messages are being recieved how is this going
to help? I guess i could launch the console part as a child process but im
not sure how that would work.

Have other people here had this problem? What path have you taken to solve
this?

You can acknowledge this as known bug in your program, and can state that
it's fixed in XP. :-)

I could, but ideally i need to cover the fact that people are still using
this platform.
