Question

我有以下程序：

打开Citrix连接中心（concentr.exe）
将窗户带到前面
发送R键（这会打开首选项）
关闭两个窗口（concentr和首选项）

以下是工作代码：

    Process.Start(@"C:\Program Files (x86)\Citrix\ICA Client\concentr.exe");
    IntPtr windowPtr = FindWindowByCaption(IntPtr.Zero, "Citrix Connection Center");
    SetForegroundWindow(windowPtr);
    SendKeys.SendWait("{r}");
    IntPtr prefWindowPtr = FindWindowByCaption(IntPtr.Zero, "Citrix Receiver - Preferences");
    SendMessage(prefWindowPtr, WM_CLOSE, IntPtr.Zero, IntPtr.Zero);
    SendMessage(windowPtr, WM_CLOSE, IntPtr.Zero, IntPtr.Zero);

我对此代码的唯一问题是使用SendKeys.SendWait发送R密钥，我希望将其替换为对SendMessage的调用。

我尝试了以下方法，但它似乎没有做任何事情：

SendMessage(windowPtr, WM_KEYDOWN, (IntPtr)0x52, IntPtr.Zero);
SendMessage(windowPtr, WM_CHAR, (IntPtr)0x72, IntPtr.Zero);
SendMessage(windowPtr, WM_KEYUP, (IntPtr)0x52, IntPtr.Zero);

我通过在记事本中运行Microsoft Spy ++来记录上述行，并记录当我按R时它的作用，它给了我以下内容：

有谁知道我哪里出错了/我应该在这做什么呢？

Answer 1

正如评论中所指出的，正确的方法是使用y。

关注this answer，我能够让它发挥作用。在声明了所有必需的结构和方法后，我成功地发送了SendInput()这样的内容：

其他声明：

void SendR()
{
    INPUT[] Inputs = new INPUT[1];
    INPUT Input = new INPUT();

    Input.type = 1; // Keyboard Input
    Input.U.ki.wScan = ScanCodeShort.KEY_R;
    Input.U.ki.dwFlags = KEYEVENTF.SCANCODE;   
    Inputs[0] = Input;

    SendInput(1, Inputs, INPUT.Size);
}

我还发现INPUT和SendInput()的文档很有用。

Citrix Receiver中自动/// <summary> /// Declaration of external SendInput method /// </summary> [DllImport("user32.dll")] internal static extern uint SendInput( uint nInputs,
