RDP session launch applications - autoit

Question

I have opened an RDP session using AutoIt. Here is the code:
$host = "" ; <---- IP
$hGUI = GUICreate("Terminal Serveur", 952, 675, -1, -1, $WS_OVERLAPPEDWINDOW + $WS_CLIPSIBLINGS + $WS_CLIPCHILDREN)
$oRDP = ObjCreate("MsTscAx.MsTscAx.2")
$oRDP_Ctrl = GUICtrlCreateObj($oRDP, 64, 44, 800, 600)
GUICtrlSetResizing(-1, $GUI_DOCKALL)
GUICtrlSetStyle($oRDP_Ctrl , $WS_VISIBLE)
$oRDP.DesktopWidth = 800
$oRDP.DesktopHeight = 600
$oRDP.Fullscreen = False
$oRDP.ColorDepth = 16
$oRDP.AdvancedSettings3.SmartSizing = True
$oRDP.Server = $host
$oRDP.UserName = "" ; <--- Username
$oRDP.Domain = ""
$oRDP.AdvancedSettings2.ClearTextPassword = "" ; <--- Password
$oRDP.ConnectingText = "Connecting to " & $host
$oRDP.DisconnectedText = "Disconnected from " & $host
$oRDP.StartConnected = True
$oRDP.Connect()
$oShel = ObjCreate("shell.application")
$oShel_Ctrl = GUICtrlCreateObj($oShel, 64, 44, 800, 600)
GUICtrlSetStyle($oShel_Ctrl , $WS_VISIBLE)
GUISetState(#SW_SHOW, $hGUI)
Send ("#r") ; !!
While 1
$nMsg = GUIGetMsg()
Switch $nMsg
Case $GUI_EVENT_CLOSE
$oRDP.Disconnect()
Exit
EndSwitch
WEnd
Now, I want to launch an application in the RDP session. I tried " Send(#r) " in order to send the path with a function like SendKeys but this command is execute on my computer and not on the remote computer.
How can I do please?

Answer 1

Send alt + home. This open the windows search in the rdp session, which you can then send it text e.g. send("notepad")
send({enter})

Answer 2

Update:
A much simpler alternative:
Change the Remote Desktop Connection Settings (not in the control
code, but in the usual windows shorcut. But it seems that could be done in the AutoIt code with the keyboardhook setting keyboardhook setting ) .
Look for the Options button, in the window when launching remote desktop.
On the Local Resources Tab select Windows key combinations are applied in full-screen mode only.
Change this line in your code:
$oRDP.Fullscreen = True
Include a pause to ensure the control has been loaded
Sleep(5000)
Send ("#r")
Previous answer:
Let my suggest a workaround not very 'elegant' but should work (tested ok):
In the remote desktop make a shorcut to the Windows Virtual Keyword (On-Screen Keyboard or OSK)
Find the position of the shorcut icon
In your code send a double click at this position to start the on-screen keyboard
Then send clicks to the positions of the desired keys
Something like this:
Sleep(5000)
MouseClick("left",512,191,2) ;start virtual keyword
Sleep(1000)
MouseClick("left",553,807,1) ;click
Sleep(100)
MouseClick("left",633,740,1)
Sleep(1000)
Send("notepad")
Sleep(1000)
Send("{ENTER}")
(Aside note: For any executable with a shortcut on the remote desktop simply send double click, without the need of the virtual keyboard)
