一个console程序，当按下窗口的关闭按键时，不想退出而是进行自己的处理，应如何进行。敬请指教。

Registering a Control Handler Function

This is an example of the SetConsoleCtrlHandler function that is used to install a control handler.


When a CTRL+C signal is received, the control handler returns TRUE, indicating that it has handled the signal. Doing this prevents other control handlers from being called.

When a CTRL_CLOSE_EVENT signal is received, the control handler returns TRUE, causing the system to display a dialog box that gives the user the choice of terminating the process and closing the console or allowing the process to continue execution. If the user chooses not to terminate the process, the system closes the console when the process finally terminates.

When a CTRL+BREAK, CTRL_LOGOFF_EVENT, or CTRL_SHUTDOWN_EVENT signal is received, the control handler returns FALSE. Doing this causes the signal to be passed to the next control handler function. If no other control handlers have been registered or none of the registered handlers returns TRUE, the default handler will be used, resulting in the process being terminated.

Note that MyErrorExit is a placeholder for an application-defined function to display and handle error conditions.

BOOL CtrlHandler(DWORD fdwCtrlType)
{
switch (fdwCtrlType)
{
// Handle the CTRL+C signal.

case CTRL_C_EVENT:

Beep(1000, 1000);
return TRUE;

// CTRL+CLOSE: confirm that the user wants to exit.

case CTRL_CLOSE_EVENT:

return TRUE;

// Pass other signals to the next handler.

case CTRL_BREAK_EVENT:

case CTRL_LOGOFF_EVENT:

case CTRL_SHUTDOWN_EVENT:

default:

return FALSE;
}
}

void main(void)
{
BOOL fSuccess;

fSuccess = SetConsoleCtrlHandler(
(PHANDLER_ROUTINE) CtrlHandler, // handler function
TRUE); // add to list
if (! fSuccess)
MyErrorExit("Could not set control handler");
}

控制台程序的事件处理

[zh237]

使用这种方法的话，对于事件CTRL_CLOSE_EVENT，系统只给你5秒的时间进行处理，如果没有在5秒内自己调用exitprocess()退出，系统会弹出是否要强制关闭的对话框，以上还是在处理完后返回true的情况。如果返回false的话，系统会进入默认的处理自动调用exitprocess退出的。
我想要的是能够不弹出是否要强制关闭的对话框的处理方法。
