Hide console of Windows Application
提问by ufukgun
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?
我有一个 Qt 应用程序，当我运行这个应用程序时，它后面会打开一个控制台。在开发中，这很好，因为我在控制台上看到调试输出，但是当我想将此可执行文件提供给客户时，应该没有控制台窗口。我该如何隐藏它？

In the project build linker options set
在项目构建链接器选项中设置
/SUBSYSTEM:windows
/ENTRY:mainCRTStartup
Or use the following #pragmain the source file with the int main(...)
或者在源文件中使用以下#pragmaint main(...)
#pragma comment(linker, "/SUBSYSTEM:windows /ENTRY:mainCRTStartup")

It sounds like your linker configuration is incorrect. Right-click the project, Properties, Linker, System, SubSystem setting. Make sure "Windows" is selected, not "Console".
听起来您的链接器配置不正确。右键单击项目、属性、链接器、系统、子系统设置。确保选择了“Windows”，而不是“控制台”。
And, change main() to WinMain().
并且，将 main() 更改为 WinMain()。

You can get rid of the console by calling:
您可以通过调用来摆脱控制台：
FreeConsole();

i use that method and it worked
我使用这种方法并且它有效
HWND hwnd = GetConsoleWindow();
ShowWindow(hwnd, 0);

Next solution ;)
下一个解决方案;)
Env: WixXP x64, msvs 2008, Qt v4.5.3
环境：WixXP x64，msvs 2008，Qt v4.5.3
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
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 ); }
设置项目设置/配置属性/链接器/系统/子系统 = Windows (/SUBSYSTEM:WINDOWS)
但是对于 x64 有链接器错误：LNK2019: unresolved external symbol _WinMain referenced in function _WinMainCRTStartup" 为了避免它
替换以下代码：
int main(int argc, char *argv[]) { QApplication app(argc, argv); // your code* }经过
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.
它适用于 Win32 和 x64 平台。

If you use Properties->Linker->System->SubSystem| Windows
如果使用属性->链接器->系统->子系统| 视窗
And get a linker error.
并收到链接器错误。
You can look at Linker->Advanced-> Entry Point
你可以看看Linker-> Advanced-> Entry Point
and set the value to the name of your "main" function.
并将值设置为“main”函数的名称。
That is your Entry Point becomes, main, if your main function is a "main".
如果您的主要功能是“主要”，那么您的入口点将变为主要。

May be the better option will be not to simply remove (as Andy M suggested) but edit *.pro file adding something like
可能更好的选择不是简单地删除（如 Andy M 建议的那样）而是编辑 *.pro 文件添加类似的东西
CONFIG(debug, debug|release) {
CONFIG *= console
}
else {
CONFIG -= console
}
In debug you can see console window but not in release. I like it. =)
在调试中，您可以看到控制台窗口，但在发布中看不到。我喜欢。=)

I would suggest to check the presence of the following line in your .PRO file :
我建议检查您的 .PRO 文件中是否存在以下行：
CONFIG += console
If you can find it, remove it ! It should fix your issue !
如果你能找到它，删除它！它应该可以解决您的问题！
Hope it helps !
希望能帮助到你 ！

For those of you editing the .vcxproj directly, you want to add a SubSystemwith the value Windowsto your LinkItemDefinitionGroupas follows:
对于那些直接编辑.vcxproj，要添加一个SubSystem与价值Windows，以你的LinkItemDefinitionGroup，如下所示：
<ItemDefinitionGroup>
<Link>
<SubSystem>Windows</SubSystem>
</Link>
</ItemDefinitionGroup>
