Q

What are the differences between the two input methods: “Send Windows Messages” and “Simulate”?

A

Both work in the background (default does not)

Send Windows Messages: Replays the window messages that the target application receives when the mouse/keyboard is used. Slower, but less compatability issues.

Simulate: Uses the technology of the target application (API level). Faster, but some compatability issues.

Q

What are output methods used for in UiPath? What are the 3 types?

A

They are used to extract data from UI elements.

FullText
Native
OCR

22
Q

Describe the FULLTEXT Output method

A
  • Fastest of the three
  • Extracts hidden text (options in dropdown list)
  • Doesn’t support virtual env
  • Doesn’t capture text position and formatting
23
Q

Describe the NATIVE Output method

  • Extracts text position and formatting
  • Can’t extract hidden text or work in the background
  • Doesn’t support virtual env
24
Q

What is GDI

A

Optical Character Recognition

  • Works with virtual env and reading text from images
  • Captures Text position
  • Cannot work in the background
  • Slowest of the 3
26
Q

How does data scraping work?

A
  • Indicate multiple elements of the same thing (i.e. titles from a search result).
  • This creates a pattern that UiPath recognizes and generalizes to the entire page[s].
  • Can do this for multiple elements (i.e. title, publish date, etc…)
  • This is then stored in a data table and can be written to a file).
27
