[RESOLVED] Catching errorlevel from a batch file

[Neverbirth]

I know this is possible by using the GetExitCodeProcess API, the problem with it is that it just catches the code of the ending command... for example, a batch file with this code:

@echo off
copy c:\dummy.jpeg c:\

The function catches the errorlevel correctly, but if I add "echo errorlev = %ERRORLEVEL%" the GetExitCodeProcess returns a 0 as the last line isn't generating any error...

I've tried catching the exit code doing a loop this way:

ProcessId = Shell("c:\a.bat", 1)
    hProcess = OpenProcess(PROCESS_QUERY_INFORMATION, False, ProcessId)
 
    Do
 
        Call GetExitCodeProcess(hProcess, exitCode)
        DoEvents
   
    Loop While exitCode <> 0
 
    CloseHandle hProcess

But it only gets the exitCode = 259, which is the corresponding one to the process still being active...

Is this possible without having to resort to something like "echo %ERRORLEVEL% > errors.txt"?

Well, notice some hours ago that I can force the exit code at any moment by doing simply "exit n", so it's just a matter of checking the ERRORLEVEL value each time to see if some error was generated.

If echo errorlev = %ERRORLEVEL% doesn't throw an error, the exit error of the batch process is 0. There's only 1 error level for a program, and that's the one it sets when it exits. You can save error levels locally (in the batch process) and force an exit level based on a previous error, even though the process has since completed a few further steps with no error.
