Hi,

Hi @hm00776818

Have you tried with element exist aactivity?

@hm00776818 - What I use is a combination of Try Catch and Use Application/Browser:

I put a Use Application/Browser inside Try. If the robot is unable to see the page despite loading with the correct URL, it will throw a System Exception:

And then in Catch, I add a System Exception catch where I add all activities I need to do if the page does not exist:

This is the most basic approach I do and there are situations where I add a Parallel activity to make the process faster especially if I know in advance what other kinds of pages could show when I attempt to load a non-existent page. Let me know if the above suggestion helps you or if you need more help.

Thanks!

its a better instead of this one use application browser we can continuous error on true and in that output we can create one element and the element type is uielement.

now i can pass this element type to check app state it will check that page is exist or not.

in this situation i dont want to go to any try catch?

Personally, I use Continue On Error = True as a last resort because using that property allows the robot to go to the next activity but we don’t have any idea what kind of error it tripped on.

By doing a Try Catch, we have a chance to systemmatically identify what the error is and safely let through only the ones that we decide can go through (like the non-existence of the page). This will allow you to save headache when the robot is live and there’s a new kind of error happening but difficult to detect because the Continue On Error = True property is just set to True.

yes i agree but is it a good practice use try/catch to detect that particular window exist to check becuse UiPath have already option use check app state?

Hi @hm00776818

Check app state activity is the replacement of all the activities mentioned below.

If your primary goal is to check whether a specific window exists, and you want a clean and efficient way to handle this scenario, it’s generally better to use the “Check App State” activity. This activity is purpose-built for window existence checking and is more straightforward.

Use try/catch blocks when you need to handle more complex scenarios or when you want to customize error handling logic beyond just checking for window existence. Try/catch blocks are powerful for managing exceptions and errors but may add unnecessary complexity if the primary goal is window existence checking.
