Question

我想显示SIP，但是我想在屏幕上显示它比默认显示的更高。有没有办法垂直定位SIP？

Answer 1

是的，但这取决于您运行的平台;并非SIP的所有实现都可以让您移动它，特别是那些在Windows Mobile上。（Windows Mobile在Windows CE上基于，本质上是通过Platform Builder创建的特定版本，但并非所有运行Windows CE的设备都插入了相同的平台组件。）I blogged about doing this in an application that runs on a version of Windows CE a few months ago.你那里会找到示例C＃代码。

Answer 2

在清除SetSipInfo和所需位置的情况下致电SIPF_DOCKED bit。

Answer 3

/// <summary>
/// Sets the location of the SIP
/// </summary>
/// <param name="x">x coordinate of the SIP</param>
/// <param name="y">y coordinate of the SIP</param>
public static void SetSipLocation(int x, int y)
{
    try
    {
        NativeMethods.SIPINFO info = new NativeMethods.SIPINFO();
        info.cbSize = Marshal.SizeOf(info);

        if (NativeMethods.SipGetInfo(out info))
        {
            info.rcSipRect.right = (info.rcSipRect.right -
                info.rcSipRect.left) + x;
            info.rcSipRect.left = x;

            info.rcSipRect.bottom = (info.rcSipRect.bottom -
                info.rcSipRect.top) + y;
            info.rcSipRect.top = y;

            NativeMethods.SipSetInfo(out info);
        }
    }
    catch (DllNotFoundException)
    {
    }
    catch (MissingMethodException)
    {
    }

}

在NativeMethods类中：

    /// <summary>
    /// This function receives information including the state of the software-based input panel, the area of the desktop that is not obscured by the software-based input panel, the screen coordinates of the software-based input panel, and information about the input method (IM) that the software-based input panel is currently using.
    /// </summary>
    /// <param name="info">[out] Pointer to the SIPINFO structure that contains information about the current software-based input panel.</param>
    /// <returns>TRUE indicates success. FALSE indicates failure. To get extended error information, call GetLastError.</returns>
    [DllImport("coredll.dll")]
    [return: MarshalAs(UnmanagedType.Bool)]
    internal static extern bool SipGetInfo(out SIPINFO info);

我可以在.NET Compact Framework中控制SIP（软件输入面板）的位置吗？
