我有一个小程序,使用系统keybd_event模拟ctr + c和ctr + v(复制和粘贴)事件。问题在于,程序运行后,计算机将继续像按下ctrl键一样继续运行,然后-如果键入a,它将选择整个文档,如果滚动鼠标滚轮,它将更改文本的侧面,依此类推。不仅在Visual Studio编辑器中,而且在该程序以Word等身份运行时打开的任何其他程序中。
这是我的代码:

    //The system keyboard event.
    [System.Runtime.InteropServices.DllImport("user32.dll", SetLastError = true)]
    static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);

    public const int KEYEVENTF_EXTENDEDKEY = 0x0001; //Key down flag
    public const int KEYEVENTF_KEYUP = 0x0002; //Key up flag
    public const int VK_LCONTROL = 0xA2; //Left Control key code
    public const int C = 0x43; // C key code
    public const int V = 0x56; // V key code

    static void Main(string[] args)
    {
        Thread.Sleep(1000);// So I have time to select something.

        //Simulate ctrl+c
        keybd_event(VK_LCONTROL, 0, KEYEVENTF_EXTENDEDKEY, 0);
        keybd_event(C, 0, KEYEVENTF_EXTENDEDKEY, 0);
        keybd_event(C, 0, KEYEVENTF_KEYUP, 0);
        keybd_event(VK_LCONTROL, 0, KEYEVENTF_KEYUP, 0);

        //Simulate ctrl+v
        keybd_event(VK_LCONTROL, 0, KEYEVENTF_EXTENDEDKEY, 0);
        keybd_event(V, 0, KEYEVENTF_EXTENDEDKEY, 0);
        keybd_event(V, 0, KEYEVENTF_KEYUP, 0);
        keybd_event(VK_LCONTROL, 0, KEYEVENTF_KEYUP, 0);
    }

有人知道我该怎么做才能解决这个问题?

最佳答案

这是解决方案,这完全为我工作。注意发送到keybd_event的参数中的更改。我使用了CodeProject的文章,链接:http://www.codeproject.com/Articles/7305/Keyboard-Events-Simulation-using-keybd-event-funct。这是我修复的代码:

    //The system keyboard event.
    [System.Runtime.InteropServices.DllImport("user32.dll", SetLastError = true)]
    static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);
    public const int KEYEVENTF_KEYUP = 0x0002; //Key up flag
    public const int VK_CONTROL = 0x11; //Control key code
    public const int C = 0x43; // C key code
    public const int V = 0x56; // V key code

    static void Main(string[] args)
    {
        Thread.Sleep(1000);// So I have time to select something.

        // Simulating Ctrl+C
        keybd_event(VK_CONTROL, 0x9d, 0, 0); // Ctrl Press
        keybd_event(C, 0x9e, 0, 0); // ‘A’ Press
        keybd_event(C, 0x9e, KEYEVENTF_KEYUP, 0); // ‘A’ Release
        keybd_event(VK_CONTROL, 0x9d, KEYEVENTF_KEYUP, 0); // Ctrl Release

        // Simulating Ctrl+V
        keybd_event(VK_CONTROL, 0x9d, 0, 0); // Ctrl Press
        keybd_event(V, 0x9e, 0, 0); // ‘A’ Press
        keybd_event(V, 0x9e, KEYEVENTF_KEYUP, 0); // ‘A’ Release
        keybd_event(VK_CONTROL, 0x9d, KEYEVENTF_KEYUP, 0); // Ctrl Release
   }

希望对您有所帮助。感谢所有帮助我的人!
