problems with forcibly closing the .exe

ask_you

Firstly, the application that i developed closes forcibly when i press ENTER. which event should i handle so that the the application does respond to ENTER command. Secondly, from the task manager when i select my application and do end process, the application closes forcibly. Which event should i handle in these case so that my app does some clean-up operation which i would like to do on exit. ask_you

Firstly, the application that i developed closes forcibly when i press ENTER. which event should i handle so that the the application does respond to ENTER command. My guess is that you are writing a dialog-based app and there's an OK button in it. The easy way to prevent the program from closing when you hit ENTER is to 1) change the ID of the OK button from IDOK to IDC_OK 2) Delete the OnOK handler from your code. 3) Add a new handler for IDC_OK. Of course, there may be other ways to accomplish the same end, but I'm not really in a position to suggest anything more complex right now. ---------- Secondly, from the task manager when i select my application and do end process, the application closes forcibly. Which event should i handle in these case so that my app does some clean-up operation which i would like to do on exit. Handdle cleanup in the destructor of the dialog if possible. If you need to, you can also use the destructor for the app, or even OnExitInstance. ------- sig starts "I've heard some drivers saying, 'We're going too fast here...'.

Well, you haven't even described your application, so how the hell can I (or anyone) help you? WHY does your program close down when you press ENTER? One final note - show us some freakin respect and SPELL everything out. You're not texting over a goddamn phone, so "any1" and "u" are not acceptable and only serve to annoy the literate members of this board. ------- sig starts "I've heard some drivers saying, 'We're going too fast here...'.

Is it dialog based? Then you probably deleted the OK and CANCEL button of the resources? Override the OnOK function (and leave it empty if it doesn't need to do something) If it fails try also overriding the OnCancel function. hope it helps.

there is nothing much to speak out. its a dialog based app without any OK. The application minimizes to the tray when i click on the close. In the tray when it is minimized, i create a pop-up menu on right-clicking the icon. From this menu i exit..... Now, my application closes on pressing ENTER. if i knew why it closes, i would not have posted a message in this forum. My intention was never to annoy literate members in this board... ask_you

Thanx V. I had removed the OK button from the dialog box.. but its implementation remained!!! I commented it. it worked... thanx but my other question remains... how to handle the event in my when someone does end process from the task manager.. Is it possible to handle??

I'm half-surprised that when killing an application with the task manager it does not go thrue the exitinstance method !?!?! maybe have a look at signal and handle SIGTERM

Did you see that he said "end the process"? There's two ways to stop an app in task manager, and he implies that he's using the "End Process" button on the Processes tab. When you do that, Task Manager displays a warning that this is a last-resort method for shutting an app down because it DOES NOT DO CLEANUP. His app is probably freezing up tighter than a 40-year-old virgin, forcing him to use End Process on it. If the original poster was better at communication, this thread wouldn't be as long as it is, and he would at least be looking for the real problem instead of trying to hide it by trying to fudge in some clean-up code. ------- sig starts "I've heard some drivers saying, 'We're going too fast here...'.
