C ++如何在启动时隐藏控制台窗口？ [英] C++ How do I hide a console window on startup?

问题描述

我想知道如何在启动时隐藏控制台窗口。

I want to know how to hide a console window when it starts.

它是用于键盘记录程序的，但这不是我的意图入侵某人。这是我想做的一个学校项目，目的是展示有关黑客的危险。

It's for a keylogger program, but it's not my intention to hack someone. It's for a little school project that I want to make to show the dangers about hackers.

到目前为止，这是我的代码：

Here's my code so far:

#include <cstdlib>
#include <iostream>
#include <Windows.h>

using namespace std;

int main()
{

    cout << "Note. This program is only created to show the risk of being unaware of hackers." << endl;
    cout << "This program should never be used to actually hack someone." << endl;
    cout << "Therefore this program will never be avaiable to anyone, except me." << endl;

    FreeConsole();

    system("PAUSE");
    return 0;
}

我看到窗口出现，并在启动时立即消失。之后似乎打开了一个新控制台，只是空白。 （空白表示按任意键以继续。我想知道是否与 system（ PAUSE））有任何关系

I see the window appear and immediately disappear at startup. It seems to open a new console right after that, which is just blank. (By blank I mean "Press any key to continue.." I'm wondering if it has anything to do with system("PAUSE"))

所以我想知道为什么它要打开一个新的控制台，而不是只创建和隐藏第一个控制台。

So I want to know why it opens a new console, instead of only creating and hiding the first one.

谢谢。 ：）

推荐答案

要按需隐藏/显示控制台窗口，可以使用以下功能：
可以使用 ShowWindow 。 GetConsoleWindow 检索窗口控制台使用的句柄。
IsWindowVisible 可用于检查窗口（在这种情况下为控制台）是否可见。

To literally hide/show the console window on demand, you could use the following functions: It's possible to hide/show the console by using ShowWindow. GetConsoleWindow retrieves the window handle used by the console. IsWindowVisible can be used to checked if a window (in that case the console) is visible or not.

#include <Windows.h>

void HideConsole()
{
    ::ShowWindow(::GetConsoleWindow(), SW_HIDE);
}

void ShowConsole()
{
    ::ShowWindow(::GetConsoleWindow(), SW_SHOW);
}

bool IsConsoleVisible()
{
    return ::IsWindowVisible(::GetConsoleWindow()) != FALSE;
}
