trap autoit errors to function ?

[jennico]

hi there,

i would like to have the possibility to trap any autoit error (not com error) and lead it to an individual function where i can decide what to do now (maybe restart the script...).

the autoit built in error box ("error in line -1") is a little bit ... ambarassing when you publish an autoit built exe. i would prefer an individual error message.

is it possible by now ?

( i thought about a program launcher which starts the exe with "run" as a child process and reads the standard_i/o_flag stream, but i am not sure if that would catch the error ? )

anyone tried something like that before ?

regards

j.

That might be a very difficult thing to implement - think about that most of AutoIt commands can set the @error flag and those who doesn't, can fail due to some incorrect parameter.

Adding an error check after every command it's not an option - it will double (at least) your script's length and the error handling function can become huge.

StdErr might provide a solution but I'm not an expert in working with.

Good luck,

[jennico]

maybe it's a feature request, but why not implement an option "onAutoitError('myerrorfunc')" at least for compiled scripts and put the detailed kind of error in a macro ?

That could look a lot more professional then, no ? and one could write the error to a log file if necessary.

regards j.

(once ago i had an autoit program online that happened to crash on certain computers and on others it went fine. Since the users only had the standard autoit "line -1" message, it took me two weeks to isolate the error that was only related to french and spanish codepages and for myself by no means reproductable.)

well, i got it !

the stderror or stdread stream does not work. but i found a different way:
