c# - TabTip 键盘 c# 的设置位置不起作用

Question

我试图重新定位 TabTib 键盘但没有成功，SetWindowPos 函数返回“True”但键盘没有移动。我在 Windows 7 上使用 C#。

` [DllImport("user32.dll")] public static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

    [DllImport("user32.dll")]
    static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X,
    int Y, int cx, int cy, uint uFlags);

    [DllImport("user32.dll")]
    static extern bool SetForegroundWindow(IntPtr hWnd);
    [DllImport("user32.dll")]
    static extern IntPtr FindWindow(string ClassName, string WindowName);

    [DllImport("user32.dll")]
    [return: MarshalAs(UnmanagedType.Bool)]
    static extern bool GetWindowRect(IntPtr hWnd, out RECT lpRect);
    [StructLayout(LayoutKind.Sequential)]
    public struct RECT
    {
        public int Left;        // x position of upper-left corner
        public int Top;         // y position of upper-left corner
        public int Right;       // x position of lower-right corner
        public int Bottom;      // y position of lower-right corner
    }

    Rectangle KeyboardRect;
    IntPtr TabTipHandle;

   IntPtr GetWindowHandle()
    {
        return FindWindow("IPTip_Main_Window",null);
    }

   bool MoveKeyBoard(IntPtr hWnd, int ToX, int ToY)
    {
       return SetWindowPos(hWnd, this.Handle, ToX, ToY, KeyboardRect.Width, KeyaboardRect.Height, 0x0045);
    }
    void StartKeyboard()
    {
        Process.Start(@"C:\Program Files\Common Files\Microsoft Shared\ink\TabTip.exe");
        TabTipHandle = GetWindowHandle();
        KeyboardRect = GetKeyboardRect(TabTipHandle);
        textBox1.Text = KeyaboardRect.Top.ToString() + ", " + KeyboardRect .Left.ToString()      + ", " + KeyboardRect .Width.ToString() + ", " + KeyboardRect .Height.ToString();

        MoveKeyBoard(TabTipHandle, 100, 100);
        KeyboardRect = GetKeyboardRect(TabTipHandle);
        textBox2.Text = KeyaboardRect.Top.ToString() + ", " + KeyboardRect .Left.ToString()      + ", " + KeyboardRect .Width.ToString() + ", " + KeyboardRect .Height.ToString();
     }
    void button1_Click(object sender, EventArgs e)
    {
      StartKeyboard();
    }
    void button2_Click(object sender, EventArgs e)
    {
        MoveKeyBoard(TabTipHandle, 200, 100);
        KeyboardRect = GetKeyboardRect(TabTipHandle);
        textBox2.Text = KeyboardRect .Top.ToString() + ", " + KeyboardRect .Left.ToString()      + ", " + KeyboardRect .Width.ToString() + ", " + KeyboardRect .Height.ToString();

    }

如果您在创建流程后稍作延迟，它将起作用:

 Process.Start(@"C:\Program Files\Common Files\Microsoft Shared\ink\TabTip.exe");
 await Task.Delay(150); // Just a tiny delay before continuing
 ...
 MoveKeyBoard(TabTipHandle, 100, 100);
 ...

但是现在我遇到了一个奇怪的问题，即使用 SetWindowPos 时键盘不会准确地定位在我想要的位置。窗口似乎围绕该点摆动，直到多次调用 SetWindowPos 后它才保持不动。很奇怪，如果你问我的话。由于缺少任何文档，我搜索了注册表，因为我注意到 TabTip.exe 将在它关闭的完全相同的位置启动。所以我找到了这两个 DWORD 注册表值:

HKCU\SOFTWARE\Microsoft\TabletTip\1.7\OptimizedKeyboardRelativeXPositionOnScreen
HKCU\SOFTWARE\Microsoft\TabletTip\1.7\OptimizedKeyboardRelativeYPositionOnScreen

我对这些值进行了试验，似乎在开始该过程之前将两者都设置为 50000 会将键盘的左上角定位到屏幕中央。将两者都设置为 0 会将其准确定位在左上角，而将两者都设置为 100000 则相应地表示右上角。
