调用 osk.exe 的问题

如何解决调用 osk.exe 的问题

在研究如何使 osk 可见时，我找到了下面的代码，创建了一个新的解决方案，添加了 2 个按钮，粘贴到代码中，它完美地工作。 当我将它添加到我一直在研究的解决方案中时，什么也没发生：

Public Class Form1
    Declare Function Wow64disableWow64FsRedirection Lib "kernel32" (ByRef oldvalue As Long) As Boolean
    Declare Function Wow64EnableWow64FsRedirection Lib "kernel32" (ByRef oldvalue As Long) As Boolean
    Private osk As String = "C:\Windows\System32\osk.exe"
    Private pOSK As Process = nothing

Private Sub Keyboard_Show()
        'An instance is running 
        For Each pkiller As Process In Process.GetProcesses
            If String.Compare(pkiller.ProcessName,"osk",True) = 0 Then pOSK = pkiller
        Next

        'If no instance of OSK is running than create one depending on 32/64 bit
        For Each pkiller As Process In Process.GetProcesses
            If Not (String.Compare(pkiller.ProcessName,True) = 0) And (pOSK Is nothing) Then

                Dim old As Long
                If Environment.Is64BitOperatingSystem Then ' returns true
                    '64 Bit
                    If Wow64disableWow64FsRedirection(old) Then ' returns false
                        pOSK = Process.Start(osk)
                        Wow64EnableWow64FsRedirection(old)
                    End If


                Else
                    '32 Bit
                    pOSK = Process.Start(osk)
                End If
                Exit For
            End If
        Next
    End Sub

 Public Sub Keyboard_Show()
        'An instance is running 
        For Each pkiller As Process In Process.GetProcesses
            If String.Compare(pkiller.ProcessName,True) = 0) And (pOSK Is nothing) Then

                Dim old As Long
                If Environment.Is64BitOperatingSystem Then
                    '64 Bit
                    If Wow64disableWow64FsRedirection(old) Then
                        pOSK = Process.Start(osk)
                        Wow64EnableWow64FsRedirection(old)
                    End If
                Else
                    '32 Bit
                    pOSK = Process.Start(osk)
                End If
                Exit For
            End If
        Next
    End Sub

在我的实际项目上运行时， If Environment.Is64BitOperatingSystem Then 返回 True，但
If Wow64disableWow64FsRedirection(old) Then 返回 False

出于故障排除目的，我尝试避免使用整个子例程而仅使用
Process.Start("c:\windows\system32\osk.exe") 抛出异常：
System.ComponentModel.Win32Exception: 'The requested operation requires elevation.'

想法？任何帮助将不胜感激！
