103,104 ,105 Use of OCR Engines .Can we define or Modify by using Variables

[Harsha_S1 (Harsha S)]

Scenario 103: Is Tesseract OCR free to use in UiPath, or do we need to buy a license? What about Microsoft OCR?

Scenario 104: Can we edit the selectors by using Variables?

Scenario 105: In Short, What is the use of RE-Framework, rather than showing the System Exception and Business Exceptions?

Unable to get solutions for the above scenarios. Please Clarify.

Thanks in Advance.

103: Read the below for
Microsoft OCR: https://docs.uipath.com/activities/docs/microsoft-ocr
Tesseract OCR: https://docs.uipath.com/activities/docs/google-ocr

104: Yes you can. To clarify, do you want to use some dynamic elements or replace the complete selectors by passing a complete dynamic selector?

105: REFrameowrk helps you simplify the structure of the automation you’re building. Easily identify errors. And more importantly, separating each part into different states. You can add/remove the state as per your requirements but that is the basic structure.
To understand this in a more detailed way try to a create process in REFramework and then create the same without it you will identify the challenges.

Hope this helps. Let me know if you still have questions.

Cheers,

Hi,

Thanks for your response!!

Still, I am unable to judge. Can we edit the selectors rather than using “*” and “?”.
Is there any possibility to store under the variables and can we pass the variables as our requirement?

Hi @Harsha_S1 ,

Check on the below answers provided :

Scenario 103: Is Tesseract OCR free to use in UiPath, or do we need to buy a license? What about Microsoft OCR?

Yes, It does not require a License. It is available in UiPath Studio like any normal activity.

Scenario 104: Can we edit the selectors by using Variables?

Yes. We can edit selectors by using variables. Check below post for more info :

How to use variables in selectors in Studio (dynamic selectors) without string manipulation!

I am only seeing choose/create variable in the context menu, but in my case I am trying choose an argument, which I see as an option in your screenshot. Any settings that I need to change? Edit: Just to be clear, I do understand that I can assign the value of the argument to a variable and accomplish the same thing, just trying to do it in the cleanest way possible.

Scenario 105: In Short, What is the use of RE-Framework, rather than showing the System Exception and Business Exceptions?

The RE-Framework is already a built-in framework provided by UiPath. It would mean there are already built-in mechanisms that could help us in developing a better automation. Such as Retry mechanism on an Unexpected Exception, Handling of Business Exceptions, Entry and Exit Stages of an Automation Project. Along with that it makes the scalability of the automations much flexible to be used.

Re-framework applicability and usage

Hello guys, As a RPA developer, almost each one of us face a dilemma on whether to use re-framework or not whenever we are in the process of designing solutions for various problem statements. I go through this dilemma every now and then. I even used to think this framework is only meant to be used for scenarios having orchestrator queues but that’s not the case. So I thought of sharing this with all of you. Re-framework can be used for repetitive process scenarios where …

Yes, you can pass the variables as well. That is also an option. Check this for the same: https://rpatools.com/2020/11/how-to-use-dynamic-variable-in-the-selectoruipath/
