AutoIT hard crashes... tolerated?

Recommended Posts

Spiff59

I'm not sure what the policy here is towards AutoIT3.exe abends.

Whether people doing stupid things that crash AutoIT is chalked up to people just being stupid, or, whether the intent is to have AutoIT bulletproof from abnormal terminations.

Anyway, I (ignorantly) tried tacking a third parm, one that is valid for the .NET SetEnvironmentVariable method, onto the Kernal32 SetEnvironmentVariable function.

$ret = DllCall("Kernel32.dll", "int", "SetEnvironmentVariable", "str", "TestVar", "str", "Value123", "int", 2)

Autoit3.exe didn't respond well.

Whether it's something that ought to be fixed or not, I don't know (or particularily care).

But a quick search in Bug Track on "DllCall" didn't turn up anything closely related, so I thought I'd report it.

The crash is your fault, not AutoIt's.

.net runtime != windows api

Also irrelevant in the context of this thread.

Your comment isn't? :graduated:

DllCall allows uncontrolled access to the outside, hence it's the scripters responsibility to ensure compability. I dont think stack control should be added, however if desired, one could look at python code which does this.


Ever wanted to call functions in another process? ProcessCall UDFConsole stuff: Console UDFC Preprocessor for AutoIt OMG

My call about it being irrelevent was meant to indicate the fact that the .Net runtime and the Windows API being different was not the problem.
