Konvertieren DirectInput-Codes in Keycodes. NET

Question

Ich muss einen Weg finden, DirectInput-Codes in. Net-Keycodes zu konvertieren. Verzeihen Sie, das ganze Schlüssel-Input-Ding verblüfft mich. Das Beispiel wäre, wenn ich einen Schlüssel über packen:

Private Sub GetKey(sender As Object, e As PreviewKeyDownEventArgs) Handles SnapKeyName.PreviewKeyDown 
     Dim KeyCode = e.KeyCode 
End Sub 

und drücken Sie „C“ Ich habe einen Schlüsselcode von 67 erhalten jedoch Ich entwickle ein Plugin für eine App, die Tastenanschläge in Directinput-Format zurückgibt. Dies liefert "C" als 46.

Ich brauche eine Möglichkeit, um inputput in .keycode Format zu konvertieren. Verzeihen Sie, wenn meine Terminologie falsch ist, aber nach stundenlangem Googlen völlig verwirrt.

Vergesst nicht. Hab in der Zwischenzeit einen Weg gefunden. Erstaunt konnte nirgendwo eine Antwort finden!

<DllImport("user32.dll")> 
    Private Shared Function MapVirtualKeyEx(uCode As UInteger, uMapType As MapVirtualKeyMapTypes, dwhkl As IntPtr) As UInteger 
    End Function 

    ''' <summary>

     ''' uCode is a virtual-key code and is translated into a scan code. 
     ''' If it is a virtual-key code that does not distinguish between left- and

     ''' If there is no translation, the function returns 0. 
     ''' </summary> 
     MAPVK_VK_TO_VSC = &H0

     MAPVK_VSC_TO_VK_EX = &H3 

     ''' <summary>

     ''' </summary> 
     MAPVK_VK_TO_VSC_EX = &H4 
    End Enum 

Beispiel für die Verwendung (mit Directinput/Scancode für "C"):

debug.writeline("VK for Scancode 46: " & MapVirtualKeyEx(46, MapVirtualKeyMapTypes.MAPVK_VSC_TO_VK, Nothing)" 

67 Produziert (der Virtual-Code ist für "C")
