如何以编程方式禁用C#控制台应用程序快速编辑模式?

我已经尝试了几个找到的解决方案,比如一个 - >

但是,我观察到GetConsoleMode(IntPtr hConsoleHandle,out int mode)中的模式对于不同的控制台应用程序会有所不同。它不是恒定的。

我是否可以在控制台应用程序上禁用鼠标单击(右/左按钮)以实现相同的方案。我发现它可以用IMessageFilter完成,但仅适用于Window Form Application而不适用于控制台应用程序。

请指导。

对于像我这样喜欢 no-brainer 代码进行复制/粘贴的人,这里的代码灵感来自接受的答案:

using System;
using System.Runtime.InteropServices;

static class DisableConsoleQuickEdit {

   const uint ENABLE_QUICK_EDIT = 0x0040;

   // STD_INPUT_HANDLE (DWORD): -10 is the standard input device.
   const int STD_INPUT_HANDLE = -10;

   [DllImport("kernel32.dll", SetLastError = true)]
   static extern IntPtr GetStdHandle(int nStdHandle);

   [DllImport("kernel32.dll")]
   static extern bool GetConsoleMode(IntPtr hConsoleHandle, out uint lpMode);

   [DllImport("kernel32.dll")]
   static extern bool SetConsoleMode(IntPtr hConsoleHandle, uint dwMode);

   internal static bool Go() {

      IntPtr consoleHandle = GetStdHandle(STD_INPUT_HANDLE);

      // get current console mode
      uint consoleMode;
      if (!GetConsoleMode(consoleHandle, out consoleMode)) {
         // ERROR: Unable to get console mode.
         return false;
      }

      // Clear the quick edit bit in the mode flags
      consoleMode &= ~ENABLE_QUICK_EDIT;

      // set the new mode
      if (!SetConsoleMode(consoleHandle, consoleMode)) {
         // ERROR: Unable to set console mode
         return false;
      }

      return true;
   }
}

如果要禁用快速编辑模式,则需要调用GetConsoleMode以获取当前模式。然后清除启用快速编辑的位,并调用SetConsoleMode。假设你有非托管函数的托管原型,你会写:

const int ENABLE_QUICK_EDIT = 0x0040;

IntPtr consoleHandle = GetConsoleWindow();
UInt32 consoleMode;

// get current console mode
if (!GetConsoleMode(consoleHandle, out consoleMode))
{
    // Error: Unable to get console mode.
    return;
}

// Clear the quick edit bit in the mode flags
mode &= ~ENABLE_QUICK_EDIT;

// set the new mode
if (!SetConsoleMode(consoleHandle, consoleMode))
{
    // ERROR: Unable to set console mode
}

如果要禁用鼠标输入,则需要清除鼠标输入位。

const int ENABLE_MOUSE_INPUT = 0x0010;

mode &= ~ENABLE_MOUSE_INPUT;

已阅读以上答案,无法使用GetConsoleWindow()。而是必须使用GetStdHandle()。

因此,这是一个用于启用/禁用QuickEditMode的复制和粘贴类。调用 ConsoleWindow.QuickEditMode(false); 禁用控制台窗口的快速编辑模式。

using System;
using System.Runtime.InteropServices;

public static class ConsoleWindow
{
    private static class NativeFunctions
    {
        public enum StdHandle : int
        {
            STD_INPUT_HANDLE = -10,
            STD_OUTPUT_HANDLE = -11,
            STD_ERROR_HANDLE = -12,
        }

        [DllImport("kernel32.dll", SetLastError = true)]
        public static extern IntPtr GetStdHandle(int nStdHandle); //returns Handle

        public enum ConsoleMode : uint
        {
            ENABLE_ECHO_INPUT = 0x0004,
            ENABLE_EXTENDED_FLAGS = 0x0080,
            ENABLE_INSERT_MODE = 0x0020,
            ENABLE_LINE_INPUT = 0x0002,
            ENABLE_MOUSE_INPUT = 0x0010,
            ENABLE_PROCESSED_INPUT = 0x0001,
            ENABLE_QUICK_EDIT_MODE = 0x0040,
            ENABLE_WINDOW_INPUT = 0x0008,
            ENABLE_VIRTUAL_TERMINAL_INPUT = 0x0200,

            //screen buffer handle
            ENABLE_PROCESSED_OUTPUT = 0x0001,
            ENABLE_WRAP_AT_EOL_OUTPUT = 0x0002,
            ENABLE_VIRTUAL_TERMINAL_PROCESSING = 0x0004,
            DISABLE_NEWLINE_AUTO_RETURN = 0x0008,
            ENABLE_LVB_GRID_WORLDWIDE = 0x0010
        }

        [DllImport("kernel32.dll", SetLastError = true)]
        public static extern bool GetConsoleMode(IntPtr hConsoleHandle, out uint lpMode);

        [DllImport("kernel32.dll", SetLastError = true)]
        public static extern bool SetConsoleMode(IntPtr hConsoleHandle, uint dwMode);
    }

    public static void QuickEditMode(bool Enable)
    {
        //QuickEdit lets the user select text in the console window with the mouse, to copy to the windows clipboard.
        //But selecting text stops the console process (e.g. unzipping). This may not be always wanted.
        IntPtr consoleHandle = NativeFunctions.GetStdHandle((int)NativeFunctions.StdHandle.STD_INPUT_HANDLE);
        UInt32 consoleMode;

        NativeFunctions.GetConsoleMode(consoleHandle, out consoleMode);
        if (Enable)
            consoleMode |= ((uint)NativeFunctions.ConsoleMode.ENABLE_QUICK_EDIT_MODE);
        else
            consoleMode &= ~((uint)NativeFunctions.ConsoleMode.ENABLE_QUICK_EDIT_MODE);

        consoleMode |= ((uint)NativeFunctions.ConsoleMode.ENABLE_EXTENDED_FLAGS);

        NativeFunctions.SetConsoleMode(consoleHandle, consoleMode);
    }
}

通过下面使用的代码组合,我可以启用或禁用快速编辑模式。

const int ENABLE_QUICK_EDIT = 0x0040;

// STD_INPUT_HANDLE (DWORD): -10 is the standard input device.
const int STD_INPUT_HANDLE = -10;

[DllImport("kernel32.dll", SetLastError = true)]
static extern IntPtr GetStdHandle(int nStdHandle);

[DllImport("kernel32.dll")]
static extern bool GetConsoleMode(IntPtr hConsoleHandle, out int lpMode);

[DllImport("kernel32.dll")]
static extern bool SetConsoleMode(IntPtr hConsoleHandle, int dwMode);

要启用,请执行简单的currentConsoleMode &= ENABLE_QUICK_EDIT;

要禁用,请执行 currentConsoleMode &= ~ENABLE_QUICK_EDIT

然后调用 SetConsoleMode

我偶然发现了同一个问题,该问题在我的控制台应用程序中启用了快速编辑模式,该模式使用C语言编写,并且已经在Windows 7 32位环境下工作了很长时间。在将其移植到Windows 10 64位(仍然是32位应用程序)之后(不是真正地移植,而是修改了一些代码行),我观察到了相同的行为。 所以我寻找解决方案。

但是出于我未知的原因,该代码以相反的方式工作,即在mode参数中设置位ENABLE_QUICK_EDIT_MODE实际上禁用了快速编辑模式。重置该位将启用快速编辑模式... ???

这是我的代码:

    /// <summary>
/// This flag enables the user to use the mouse to select and edit text. To enable
/// this option, you must also set the ExtendedFlags flag.
/// </summary>
const int QuickEditMode = 64;

// ExtendedFlags must be combined with
// InsertMode and QuickEditMode when setting
/// <summary>
/// ExtendedFlags must be enabled in order to enable InsertMode or QuickEditMode.
/// </summary>
const int ExtendedFlags = 128;

BOOLEAN EnableQuickEdit()
{
    HWND conHandle = GetStdHandle(STD_INPUT_HANDLE);
    int mode;
    DWORD dwLastError = GetLastError();
    if (!GetConsoleMode(conHandle, &mode))
    {
        // error getting the console mode. Exit.
        dwLastError = GetLastError();
        return (dwLastError == 0);
    }
    else 
        dwLastError = 0;
    mode = mode & ~QuickEditMode;

    if (!SetConsoleMode(conHandle, mode | ExtendedFlags))
    {
        // error setting console mode.
        dwLastError = GetLastError();
    }
    else
        dwLastError = 0;
    return (dwLastError == 0);
}

BOOLEAN DisableQuickEdit()
{
    HWND conHandle = GetStdHandle(STD_INPUT_HANDLE);
    int mode;
    DWORD dwLastError = GetLastError();

    if (!GetConsoleMode(conHandle, &mode))
    {
        // error getting the console mode. Exit.
        dwLastError = GetLastError();
        return (dwLastError == 0);
    }
    else
        dwLastError = 0;

    mode = mode | QuickEditMode;

    if (!SetConsoleMode(conHandle, mode))
    {
        // error getting the console mode. Exit.
        dwLastError = GetLastError();
    }
    else
        dwLastError = 0;
    return (dwLastError == 0);
}
