now, i want to give this executable to the customer and i dont want to any console window. how can i hide it??

(ps. i use Visual Studio 2008)

Answer 1

Hey,

I would suggest to check the presence of the following line in your .PRO file :

CONFIG += console

If you can find it, remove it ! It should fix your issue !

Hope it helps !

Answer 2

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 3

It sounds like your linker configuration is incorrect. Right-click the project, Properties, Linker, System, SubSystem setting. Make sure "Windows" is selected, not "Console".

Answer 4

i use that method and it worked

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

Answer 5

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

1. • 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....
