read my own stdout

[mary]

hi !

My autoit script call a dll and this dll send data to stdout of caller ( i.e my compiled script). It work with other script language (python, rubby....) but not with autoit . so my question is :

is it possible to read our own stdout ?

It is possible to do what you need. just look into the help file to this command: StdoutRead

StdoutRead not work !

Just a precision: what i mean is StdoutRead(@AutoItPID) ! because the dll that i call send result in stdout of caller (wich is my script )

when call this dll in SciTE Editor, it send me the result in editor without using consolewrite !

any idea ?

Hello Mary,

I have spent the past half an hour trying to get AutoIt to read the Stdout from a called dll. I wrote a simple dll, called it and tried a variety of functions, ConsoleRead(), StderrRead(), and StdoutRead. It doesn't appear that an AutoIt script can currently read its own output. This is a serious limitation. If one of the developers knows a way I am all ears. It appears that the only way you can do it right now is by reading std streams of parent and child processes. As such, there is one alternative. You could create a child script that is executed by the main AutoIt script. The child script will call the dll and then the dll will give the output. The parent AutoIt script will then receive the output of the child AutoIt process which would include the stdoutput of the called dll.

I then spent some time making an alternative way to do it. Here is how I did it just now:

Parent.au3

Dim $i_PID = Run(@AutoItExe & ' /AutoIt3ExecuteScript "child.au3"',"",@SW_HIDE,1+2+4)
Dim $s_Output
While ProcessExists($i_PID)
    $s_Output = StdOutRead($i_PID)
    MsgBox(0,"Output:",$s_Output,1)
    ConsoleWrite($s_Output)
WEndoÝ÷ Ø(b֮ݫ­¢+Ù¥´ÀÌØí¡}±°ô±±=Á¸ ÅÕ½ÐíM¥µÁ±=ÕÑÁÕѱ±½ÉQÍй±°ÅÕ½Ðì¤)¥´ÀÌØí¥}Q¥µÈôQ¥µÉ%¹¥Ð ¤)¥´ÀÌØí¥}IÑÕɸ)]¡¥±Q¥µÉ¥ ÀÌØí¥}Q¥µÈ¤±ÐìÔÀÀÀ((ÀÌØí¥}IÑÕɸô±±

I hope you find this useful.

I am not sure if you can connect to the STDOut stream after the program is started. Maybe DaveF knows, But,...

Taking your idea one step futher you should be able to do it in one script as well with something like this : (untested)

If $CMDLine[0] = 1 and $CMDLine[1] = "CallDll" Then
    CallDll()
    Exit
EndIf
;
;
; Call DLL that produces STDOUT
Dim $s_Output
$i_PID = Run(@ScriptFullPath & ' CallDll',"",@SW_HIDE,1+2+4)
While ProcessExists($i_PID)
    $s_Output = StdOutRead($i_PID)
    MsgBox(0,"Output:",$s_Output,1)
    ConsoleWrite($s_Output)
WEnd
;
;
Func CallDll()
    Dim $h_Dll = DllOpen("SimpleOutputDllForTest.dll")
    Dim $i_Timer = TimerInit()
    Dim $ai_Return
    While TimerDiff($i_Timer) <5000
        $ai_Return = DllCall($h_Dll,"int:cdecl","ASDF")
    WEnd
    DllClose($h_Dll)
EndFunc

thinks "The Kandie Man" !

Exactly ! it is an autoit limitation

Thinks for all tests and for your solution .

ok, for my project i'll better to code it in python.

I like autoit but....anyway
