A partial selector is a selector that does not contain the information about the top-level window. A partial selector is usually generated when a UI Automation activity is included in a container activity, such as Attach Browser or Attach Window, that has a full selector of the outer window. This way, the UI Automation activity can use the partial selector relative to the container, instead of the full selector from the root. A partial selector is indicated by the icon in the Properties panel of the UI Automation activity. In this question, the sequence that contains an activity with a partial selector is Option B, where the Click activity has the partial selector icon and is enclosed in an Attach Window activity. The other options have activities with full selectors, indicated by the icon . Therefore, the answer is B. Option B.  References :  Full Versus Partial Selectors ,  Selectors

UiPath Integration Service is a feature that enables you to integrate UI and API automation in a unified way. The three main components of UiPath Integration Service are:

Connectors: These are pre-built or custom components that provide access to various applications or systems through their APIs. You can use connectors to perform actions or retrieve data from different sources, such as Salesforce, Slack, Google Sheets, etc.  (UiPath Integration Service documentation 1 )

Connections: These are configurations that store the authentication and connection details for each connector. You can create and manage connections in the UiPath Automation Cloud and share them across different folders and processes.  (UiPath Integration Service documentation 2 )

Triggers: These are rules that define when and how to start a process in Orchestrator based on events from connectors. You can configure triggers to react to data changes, insertions, deletions, or custom events in the connected applications or systems.  (UiPath Integration Service documentation 3 )

Comprehensive and Detailed In-Depth Explanation:

When dealing with image-based documents (like scanned PDFs, screenshots, or handwritten text), the best method for extracting text is Optical Character Recognition (OCR) .

Step-by-Step Execution Guide:

Use OCR Activities in UiPath:

Tesseract OCR (free, open-source)

Microsoft OCR (Windows-based, reliable for printed text)

Google Cloud Vision OCR (for high-accuracy text recognition)

Abbyy OCR (paid, best for structured documents)

Drag and drop the Read PDF with OCR activity if dealing with PDFs or use Screen Scraping with OCR Mode if dealing with UI elements.

Choose the OCR Engine , configure properties such as scale, language, and accuracy .

Extract text and store it in a variable for further processing .

Real-World Use Case:

???? Automating Invoice Processing

A company receives scanned invoices in PDF format.

The automation needs to extract vendor details and invoice amounts .

The bot uses Tesseract OCR to extract text and Regex to filter important fields.

vb

CopyEdit

OCR_Text = " Invoice Number: 12345 Total Amount: $789.50 "

Dim match As Match = Regex.Match(OCR_Text, " Total Amount:\s*\$([\d\.]+) " )

TotalAmount = match.Groups(1).Value

???? This makes it possible to process invoices even if they are image-based.

Why the other options are incorrect?

❌ A. Screen Scraping – Partially correct , but Screen Scraping alone does not work on images unless combined with OCR.

❌ C. Regex – Regular expressions only work on text , not images. You must first extract text using OCR before applying Regex.

❌ D. String Manipulation – String manipulation is used after text extraction, not for extracting text from images .
