Hide console of Windows Application

Question

I have a Qt application, and when I run this application, there is a console opening behind it. In development it is nice because i see debug outputs on the console, but when I want to give this executable to the customer there should be no console window. how do I hide it?

(I am using Visual Studio 2008)

Answer 1

May be the better option will be not to simply remove (as Andy M suggested) but edit *.pro file adding something like

CONFIG(debug, debug|release) {
    CONFIG *= console
} 
else {
    CONFIG -= console
}

In debug you can see console window but not in release. I like it. =)

Answer 2

i use that method and it worked

HWND hwnd = GetConsoleWindow();
ShowWindow(hwnd, 0);

Next solution ;)

Env: WixXP x64, msvs 2008, Qt v4.5.3

1. Set Projects settings/Configuration properties/Linker/System/SubSystem = Windows (/SUBSYSTEM:WINDOWS)

   But For x64 there is linker error: LNK2019: unresolved external symbol _WinMain referenced in function _WinMainCRTStartup" To avoid it

2. Replace the following code:

   int main(int argc, char *argv[])
   {
        QApplication app(argc, argv);
        // your code*
   }
   

   by

   int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, char*, int nShowCmd)
   {
       int argc = 0;
       QApplication app( argc, 0 );
    }
   

It works fine for both - Win32 and x64 platforms.

Answer 4

In the project build linker options set

/SUBSYSTEM:windows
/ENTRY:mainCRTStartup

Or use the following #pragma in the source file with the int main(...)

#pragma comment(linker, "/SUBSYSTEM:windows /ENTRY:mainCRTStartup")

If you use Properties->Linker->System->SubSystem | Windows

And get a linker error.

You can look at Linker->Advanced-> Entry Point

and set the value to the name of your "main" function.

That is your Entry Point becomes, main, if your main function is a "main".
