Hi

Does anyone know how I could invoke a Windows batch file (e.g.  
MyBatchFile.bat) and check the ERRORLEVEL environment variable after the  
batch file completes execution.

Thanks

1. Try:

- `MyBatchFile.bat`
- system “MyBatchFile.bat”
- the same but with “cmd /c MyBatchFile.bat” (or /k , I don’t remember  
exactly)

$? should contain the errorlevel (exit status)

I’m writing out of my head, if that won’t help, just ask again,  
tomorrow (i.e. in 10 hours) I can provide the right solution from my  
code.
