Thread: How to send commands to an AutoIt script/program

because its very easy and i have a script open at the moment i will show u how to run a road runner command in autoit. Copy this to your .au3

Code:

;create SDK for COM with RR.  This must be done ONLY once per script
$rr = ObjCreate("RoadRunner.SDK")

;replace COMMAND with your RR command
$rr.execute("COMMAND")

and because i'm a good mood i'll show u how to request an rr label into a autoit variable as well

Code:

;trackname can be replaced with any rr label in the screens .skin file
$var=$rr.getInfo("TRACKNAME")
;to request RR variables simply use
$var=$rr.getInfo("=$musicpath$")

Code:

while 1
$var1 = $rr.getInfo(=$Var1$)
$var2 = $rr.getInfo(=$Var2$)
if $var1 = "pressed" then 
   [RUN whatever stuff u wanna do with auto it]
    $rr.execute("SETVAR;VAR1;unpressed")
end if
if $var2 = "pressed" then
    [RUN whatever stuff u wanna do with the second button]
    $rr.execute("SETVAR;VAR2;unpressed")
end if
WEnd

then instead of running RR commands with your button presses just set the appropriate variable to "pressed" (like SETVAR;VAR1;pressed) so that autoit performs that function. Quick and dirty way to do things and it works

Or from the RR source:

Code:

Global Const $StructDef_COPYDATA = "ptr;dword;ptr"
Global Const $WM_COPYDATA = 0x4A
Global Const $WM_CLOSE = 0x10
Global Const $STRUCTDEF_AU3MESSAGE = "char[255]"

Dim $cmd

; Create Reciver window
$hwmd_Reciver = GUICreate("Receiver")

; Register Windows Messages
GUIRegisterMsg($WM_COPYDATA, "_GUIRegisterMsgProc")
GUIRegisterMsg($WM_CLOSE, "_GUIRegisterMsgProc")

;Loop indefinitely - put your commands in here
While 1
If $cmd = "this" Then
  $cmd = ""
  <do this>
Endif

If $cmd = "that" Then
  $cmd = ""
  <do that>
Endif

Sleep(250)
WEnd

; Message Handler
Func _GUIRegisterMsgProc($hWnd, $MsgID, $WParam, $LParam)
	If $MsgID = $WM_COPYDATA Then
		; We Recived a WM_COPYDATA Message
		; $LParam = Poiter to a COPYDATA Struct
		$vs_cds = DllStructCreate($StructDef_COPYDATA, $LParam)
		; Member No. 3 of COPYDATA Struct (PVOID lpData;) = Pointer to Costum Struct
		$vs_msg = DllStructCreate($STRUCTDEF_AU3MESSAGE, DllStructGetData($vs_cds, 3))

		$SciTECmdLen = DllStructGetData($vs_cds, 2)
		$cmd = StringLeft(DllStructGetData($vs_msg, 1), $SciTECmdLen)

		; Display what we have recived
		MsgBox(0, "Test String", $cmd)

	ElseIf $MsgID = $WM_CLOSE Then
	; We Recived a WM_CLOSE Message
		Exit
	EndIf
EndFunc ;==>_GUIRegisterMsgProc

Once the script is running, you can send commands to it from RR via "SENDMSG;Receiver;<cmd>"

In this example, <cmd> can be "this" or "that."

*Note the the "Receiver" name has to match

Sonic's way is good too. I prefer the method above as it's more process friendly for my M10K since it just sleeps until a message is recieved.

another way is you can send command line arguments to your script at runtime, i find this works good for scripts that only run for a few secs, do there thing and exit.

search in the autoit help file for cmdlineraw

the way i normally use it is i have a command in RR that will run the script and send some bit of information from RR to the script. The script is expecting this information as cmdlineraw is a var inside of autoit.

Both of the other methods above are very good also, i use them both but depends on what the script calls for ect.

my media plugin has a LOT of sendmgs to it from rr..
