VBScript -> AutoIT Error Handling Help

[thepip3r 0]

I know you can use @error to test for errors but is there a way to check for the returned error of the command you passed to the host OS? similar to if err.number <> 0 then msgbox err.description in vbscript?

sorry, i'm sure this is a noob question.

Perhaps you mean the returned %ERRORLEVEL% from RunWait()? See help file.

could you please be more specific? I've looked through the functions, macros, and keywords and a number of other locations in the documentation and am not able to locate this %ERRORLEVEL% you speak of:

You were not specific about what "command you passed to the host OS" meant. This was the simple example I was talking about:

$iRET = RunWait(@ComSpec & ' /c DIR "C:\NoSuchDir"')
ConsoleWrite("$iRET = " & $iRET & @LF)

It returns 1 because DIR on a non-existing directory returns %ERRORLEVEL% = 1 to the shell.

If you meant a call to a COM object, then you want COM/OBJ Reference in the help file, with attention to COM Error Handlers.

right and i understand that typically functions return 0 on success, 1 on failure. what i was looking for was something equivalent to the vbscript err object. where:

if @error then

msgbox(0,"Error Occurred", err.description);

endif

...so if you pass a path to the run or exec command and the path isn't valid, err.description would report back "invalid path" or "path not found".

this may be strictly a vbscript available object but that's what i was looking for.
