Background Execution

hi there,

what code should we write so that no window is displayed on the screen. and the execution of the program takes place in the background.

thank u.

Depends on your app. Are you using MFC?

After you have created your window, there is no need to show it at all, either don't call ShowWindow() or call it with the SW_HIDE property.

Be careful, if you have no WIndow, then you do not have any ordinary way to stop your program. Normally, if I have a background task running, I put an icon in the system tray, which will popup a menu that will at lest let me stop it.

i am using c .
so it would be helpful if the code is in c / c++.

thank u.

If you are using API or manually using MFC it is a lot easier to do since you control the creation of the window/dialog (see adrianxw's post).
If you are using appwizard MFC it is not as simple, but it is possible with a few steps.

Again, it depends on your app. I wasn't talking about the language (of course you're using c/c++ silly : )). If I'm still not being clear, just tell me how you're creating the app. Are you using WinMain()? Are you creating an AppWizard MFC app in MSVC? More details, por favor.

It doesn't really matter what language you are using if you are not going to call a function. An example of not calling a function in C would look eactly the same as an example of not calling a function in C++...

...I think you really need to expand a little on what you have got so far.

This can depend on wether your using a main or WinMain function as the entry point of the application, not just code within the WinMain function. You can build console level applications that do not display a DOS box by just passing a windows flag to the compiler.
