如何解决您如何从C＃中显示/隐藏听写工具栏
我试图显示/隐藏听写工具栏，我不想简单地模拟WIN + H命令。我对UWP不太熟悉，但是听写工具栏似乎是ms-inputapp（InputHostApp.exe）的一部分。有没有办法找出WIN + H正在执行的命令以显示听写工具栏？
解决方法
这不是一个真正的答案，但这是我所能得到的。可能对某人有帮助。
这是Public Class Form2
'Class level variable declaration
Dim dblAverage As Double
Dim studentGrade As Char
Private Sub btnCalculate_Click(sender As Object,e As EventArgs) Handles btnCalculate.Click
lstOutput.Items.Clear()
Const intMAX_ROW As Integer = 2 'Highest Row subscript
Const intMAX_COL As Integer = 2 'Highest Column subscript
Dim intRow,intCol As Integer 'Row and column loop counter
Dim strName(intMAX_ROW) As String 'Name Array initilization
Dim intMarks(intMAX_ROW,intMAX_COL) As String 'Marks Array initialization
Dim intTotal As Integer
'Sum Name array through rows
For intRow = 0 To intMAX_ROW
strName(intRow) = InputBox("Enter Student name")
lstOutput.Items.Add("Test Scores for: " & strName(intRow))
'Error handling using try catch expression
Try
'Initialize accumulator
intTotal = 0
'Enter and sum Marks Column within the same row
For intCol = 0 To intMAX_COL
intMarks(intRow,intCol) = InputBox("Enter the score for test " & (intCol + 1))
If intMarks(intRow,intCol) >= 0 And intMarks(intRow,intCol) <= 100 Then
intTotal += intMarks(intRow,intCol)
Else
MessageBox.Show("Enter Marks must be between 0-100")
End If
lstOutput.Items.Add(intMarks(intRow,intCol))
Next
'To calculate average
dblAverage = intTotal / (intMAX_COL + 1)
'To Display
lstOutput.Items.Add("The total test scores for " & strName(intRow) & " is " & intTotal.ToString())
lstOutput.Items.Add("Results: ")
lstOutput.Items.Add(strName(intRow) & " Average: " & Math.Round(dblAverage) & " Grade: " & Grades())
lstOutput.Items.Add("")
Catch
MessageBox.Show("Score must be numeric between 0-100")
End Try
Next
End Sub
'Grade Condition Function
Function Grades()
If dblAverage >= 90 And dblAverage <= 100 Then
studentGrade = "A"
ElseIf dblAverage >= 80 And dblAverage <= 89 Then
studentGrade = "B"
ElseIf dblAverage >= 70 And dblAverage <= 79 Then
studentGrade = "C"
ElseIf dblAverage >= 60 And dblAverage <= 69 Then
studentGrade = "D"
Else
studentGrade = "F"
End If
Return studentGrade
End Function
Private Sub btnExit_Click(sender As Object,e As EventArgs) Handles btnExit.Click
Me.Close()
End Sub
中处理 Win + H 热键（Windows 10 v19041.508）的调用堆栈：
explorer.execoreuicomponents.Microsoft::CoreUI::Proxy::MessageProxy::Send+119
coreuicomponents.public: virtual void __cdecl Proxy_IRemoteCoreKeyboardClient$R::IRemoteCoreKeyboardClient_Impl::OnShellStateChanged(class System::Object * __ptr64,class System::Byte_1D * __ptr64,unsigned int,bool,unsigned int) __ptr64+7E

twinui.pcshell.public: long __cdecl KeyboardHosting::TabTipAdapter::OnShellHotKey(enum _TouchKeyboardShellHotKeyType) __ptr64+1E2
twinui.pcshell.public: virtual long __cdecl TouchKeyboardExperienceManager::OnShellHotKey(enum _TouchKeyboardShellHotKeyType) __ptr64+17
explorer.protected: void __cdecl CTray::_HandleDictationHotKey(void) __ptr64+67

explorer.protected: virtual __int64 __cdecl CTray::v_WndProc(struct HWND__ * __ptr64,unsigned __int64,__int64) __ptr64+48F
调用 TouchKeyboardExperienceManager::OnShellHotKey()，这可能意味着 Win + H
2通过类似于COM的某种方式使用_HandleDictationHotKey = TouchKeyboardExperienceManager::OnShellHotKey来调用IID_ITouchKeyboardExperienceManager，但是我找不到对9516d866-ca0f-40ca-8997-efa618b50f99的任何调用或类似的调用。
似乎最终可以通过某种RPC（CoCreateInstance）将消息发送到触摸键盘
