StdoutRead with Inno Setup compiler

[abberration]

Hello, all. Every month, I have to compile a lot of databases as installers for work. Sometimes, a few don't compile correctly and I would like to be able to log the failures. I am using AutoIt to start the compile process with Inno Setup's compiler. Inno's documentation says it will return a 0 or 1 depending on success or failure.

I have tried a lot of variations of this code and none of them have return anything. My first attempts was running the compiler directly (not @ComSpec). That didn't work either.

#include <CONSTANTS.AU3>
$compileProg = RunWait (@ComSpec & " /c " & "Compil32.exe /cc test.iss", "", "", $STDERR_CHILD + $STDOUT_CHILD)
$returnCode = StdoutRead ($compileProg)
MsgBox(0, "", $returnCode)

Does anyone have any suggestions?

If it says "will return a 0 or a 1" you need to read the return code, not the StdOut.

The return code can be read by Run() or RunWait():

If you assign the result of Run / RunWait to a variable, that's your returncode.

$iReturnCode = Run("ping 127.0.0.1")
ConsoleWrite("RC:" & $iReturnCode & @CRLF)
$iReturnCode = Run("ping 127.0.0.10")
ConsoleWrite("RC:" & $iReturnCode & @CRLF)

The exit code is not read when using Run, the code you get when you use Run is the PID. You only get a exit code using RunWait and ShellExecuteWait. There's no way for Run to get an exitcode because by the time the program you started has exited, the script has moved on.

BTW, don't use @ComSpec with RunWait if you want the exitcode of the program, because the exitcode you're going to get is the one from cmd.exe and not your program.

Thanks for the advice guys, but I still can't get a return code. It's possible that it just can't be done.

Try this

#include <CONSTANTS.AU3>
$returnCode = ''
$compileProg = Run (@ComSpec & " /c " & "Compil32.exe /cc test.iss", "", "", $STDERR_CHILD + $STDOUT_CHILD)
While ProcessExists($compileProg)
   $returnCode &= StdoutRead ($compileProg)
Wend
MsgBox(0, "", $returnCode)

Try this

#include <CONSTANTS.AU3>
$returnCode = ''
$compileProg = Run (@ComSpec & " /c " & "Compil32.exe /cc test.iss", "", "", $STDERR_CHILD + $STDOUT_CHILD)
While ProcessExists($compileProg)
$returnCode &= StdoutRead ($compileProg)
Wend
MsgBox(0, "", $returnCode)

Thanks for the effort, but still no dice. I'll look at it agin tomorrow.

Are you still using @Comspec to run the program when you try it? See my last post if you are.
