SendKeys from VBA to a session window

In context of the posting from mic jones here I check different ways of SendKey from an Excel VBA application to a session window.

At first I identfiy the handle of the session window and set it in foreground with the following code

Private Declare Function SetForegroundWindow Lib "user32.dll" _
  (ByVal hWnd As Long) As Long

hWnd = Session.ActiveWindow.Handle
SetForegroundWindow hWnd

After that I use different methods of SendKeys:

1. Standard VBA SendKeys, but it doesn’t work.SendKeys “+{DOWN}”, True 
2. SendKeys via SendMessage, but it doesn’t work.Private Declare Function SendMessageA Lib “user32.dll” _
     (ByVal hWnd As Long, ByVal Msg As Long, wParam As Any, lParam As Any) As Long
   
   SendMessageA hWnd, &H100, vbKeyShift, 0
   SendMessageA hWnd, &H100, vbKeyDown, 0
   SendMessageA hWnd, &H101, vbKeyDown, 0
   SendMessageA hWnd, &H101, vbKeyShift, 0
   DoEvents 
3. SendKeys via keybd_event, but it doesn’t work.Private Declare Sub keybd_event Lib “user32.dll” _
     (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
   
   keybd_event &H10, 0, 0, 0
   keybd_event &H28, 0, 0, 0
   keybd_event &H28, 0, 2, 0
   keybd_event &H10, 0, 2, 0 
4. SendKeys via Windows Scripting Host and this works very fine.Dim wsh As WshShell
   Set wsh = CreateObject(“WScript.Shell”)
   wsh.SendKeys “+{DOWN}”
   

Maybe someone can use this information or show different ways.
