How to get return value from *.exe file?

[ShawnLuo]

Hi, all,

AutoIt can compile au3 file to *.exe. My question is if the *.exe file can return a value?

and if can, how to get the return value?

I found someone says use @exitcode, but I still don't know how it works. that will be very nice if you can give me a example.

thank you so much!

I don't understand this. What do you mean by a return value?

A return value exe to exe ?

At the end of first exe, it run second exe with parameters, that second exe can get by $cmdlines

Here a small example:

#AutoIt3Wrapper_OutFile=Test.exe
#AutoIt3Wrapper_Change2CUI=y
$msg = MsgBox(4, "Return Code", "Give Exit Code true back?")
If $msg = 6 Then
    Exit(1)
Else
    Exit(0)
EndIf

Here the cmd code:

@echo off
test.exe
echo %errorlevel%

Thanks a lot, your return value can see it cmd window, but how can I get it(the return value) in my autoit script?

I cannot follow you! Your script produces the exit code and you want to pipe it back to your script? That makes not sense!

But you can use $cmdline variable to use parameter for your exe -> see Command Line Parameters in help file.

GetExitCodeProcess of course.

I'm sure there are lots of examples around.

Like this...

; The first exe
Run ( @ScriptDir & '\Second.exe ' & $_Parameterl & ' ' & $_Parameter2 )

; The second exe
If @Compiled Then
    If $CmdLine[0] < 2 Then Exit
    $_Parameterl= $CmdLine[1]
    $_Parameter2= $CmdLine[2]
EndIf

Simply only the caller can see the exit code of the your script because no code is run after the exit command.

You can have an AutoIt script call another then look at the exit code if you really must.

If you are attempting to do error handling there are other ways of doing this.
