Error Handling

[shaheen28]

Hi Folks,

I am creating a script to download a link from a webpage and uses lots of "send" keys - I understand there are mouse functions which I can use, but that will require me to spend more time to rewrite what is already written.

The program runs every 5 minutes using scheduled tasks and we have the flexibility of any iteration going wrong as the data doesnt have to be uptodate at all times. But at times (maybe once in 50) I end up gettng the "variable must be of type object" error and this results in the scheduled task to wait for user input to kill this instance. This creates the issue of requiring a manual intervention and as the cycle we need the program to run is for 12 hours, it will be difficult to man it.

Could someone please suggest if we can supress this error or maybe terminate the program itself on error by calling any error handle in the beginning of the program ?

Apologies if I am not clear on what I trying to achieve or being so dumb (not from the programming backgroung )

Thanks,

Shaheen

Welcome to AutoIt and the forum!

Supressing error messages is not a good idea! Modify the script so it runs without errors.

To download a file I would suggest function "InetGet".

Thanks mate

I had thought about the InetGet option previously, but the customer software (page) we use are running Javascripts to fetch data based on the links selected and there is no direct file location which we can use. Hence I had to go with the "send" functions.

I understand that supression of errors are not good practise, but with the current context is there a possibility of doing it as the error pops up very rarely and that too due to the incorrect tab being hit by the send function (mostly due to the delay in page). Setting delays (increasing) hasnt helped fully to remove the error though.

Cheers,

If you use Internet Explorer as your browser then I suggest to use the IE UDF that comes with AutoIt.

[shaheen28]

Program is running with FF as the browser (site requires FF and is not reliable with IE) and I havent used UDF's before (Apologies, not from programming background)

Any possibility of terminating the process upon error. Again I understand that you are trying to help me to fix the code, but with the limited time I thought to ignore the error as it is hardly one in 50.

Thanks

When you get the "variable must be of type object" error message then the script crashes (means it ends)? Or do you get a popup you have to reply to?

What exactly do you mean by "wait for user input to kill this instance"?

[shaheen28]

Apologies.

The script doesnt end and a popup is created with the error message waiting for user to input and only then the program exits. I am looking if this popup could be removed so that the script silently exits on error.

Thanks

Can you start your script with "/ErrorStdOut" as first parameter? This redirects the error message to StdOut. So no popup, no user intervention required.

[shaheen28]

I have now modified the scheduled job to include the "/ErrorStdOut" as the first parameter. Will test and come back

Thanks mate.

Thanks, I had put in an email for that. As the issue was urgent, went ahead and created another one as the original was to be deleted

Cheers,
