Is it possible to check if browser is open and close it?

[ianwuk]

Hello Everyone.

I have a browser automation flow.

I have set it up so that if an action in the flow fails then the flow restarts.

However, that means that any existing browser windows will remain open, and I want to either close them if an error occurs so that when the flow errors all browser windows or closed and a new one is opened up when the flow restarts or, if that is not possible, to somehow check to see if there are any running browser instances when the flow starts up and, if so, close them.

I hope this makes sense.  Any help is much appreciated.

Regards.

When I try this approach my flow errors and says 'BrowserInstance' must be 'Web browser instance'.

Hello,

If I am reading correct, you are checking if there are any running browser instances at the start of the Flow? Well that won't work because you have to define a browserinstance first. So the error in this case is correct: you are trying to close browsers that don't exist (especially when starting out the flow). However a workaround for this is to us en on-error at the activity which jumps to the next action when the Action fails.

I would highly advice using a try catch block on all subflows that can contain error. And have the flow jump to an Exceptionflow (where you close the browsers). 

It's kind of hard to explain what you want or need so if you need any more help feel free to ask.

Thank you for replying @OkanAT .  Your understanding is correct, and it makes sense why the error is triggered.  

I have it that the flow jumps to a subflow where the browsers are closed in the event of an error.  But even when I use an 'on error' condition to go to the next action it sometimes fails and still triggers the error 'BrowserInstance' must be 'Web browser instance', but surely it should just go to the next step?

Any suggestions?  Thanks so much!

That doesn't make sense to me why it won't work.

Another solution to the problem can be to send Keyboard Shortcuts to close browsers, back to back with intervals. For example: if you put in your flow to use the keyboard action ALT+F, 4 (max amount of browsers running) and you have 2 running at the time. Errors wont occur because after the second it would just press the keyboard shortcut and nothing would happen. This would work pretty good if you are only working with Browsers and one Browser type only.

I gotta say I don't like this approach but if it works why not.

Good luck.

Hi,

you can kill the windows processes of the browsers with a loop and action (search for service or process). Look in the Task Manager which process the browser windows uses to find out which processes to stop.

@Gidi  I just use Microsoft Edge.  So, I guess I just kill that?

My flow has one overall browser instance (Edge) and then a sub-flow creates a new browser instance off that, as a new tab.

@OkanAT Thank you so much for all your advice and suggestions, I've made a few changes to my flow based off them and I'm running it to see if the issue still occurs or not.

Thank you to you both!

Having the same needs and found this thread to discuss it. 🙂 Thanks for all of the good ideas!

I'm using another approach to tackle this issue.

Using "On block error" to attach the window, if it wan't opened, then I'll open it, if it's already openen, then I'll move on to use the page

You can use close web browser or close window activities and indicate the browser you need to close
