Generate Data Table activity generates a DataTable variable from unstructured data. This activity enables you to select column and row separators according to which the table is generated. This activity is automatically generated when using the Generate Table feature in the Screen Scraping window.

The Execution Trail ribbon button is disabled by default. When enabled, it shows the exact execution path at debugging. As the process is executed, each activity is highlighted and marked in the Designer panel, showing you the execution as it happens:
– executed activities are marked and highlighted in green;
– activities that were not executed are not marked in any way;
– activities that threw an exception are marked and highlighted in red.

Settings changed in Project Settings take effect if the corresponding property is left blank in the activity. If in the same project an activity has the Timeout property manually set (even if the value 30000 milliseconds is the same as the default one), then the value set in the property panel overwrites any other value configured in the Activity Project Settings window.

Retry Scope condition can be one of the activities that return a boolean. Even though the Path Exists activity also returns a Boolean value, it cannot be used in Retry Scope, it is an exception.
Instead of using Path Exists activity, you can use a Check True activity and as a condition place System.IO.File.Exists(filepath).

Edit password property stores the password required for editing password-protected Excel workbooks, if necessary. Only String variables and strings are supported.
While the Password property stores the password required for opening password-protected Excel workbooks, if necessary. Only String variables and strings are supported.
In this case, the password is set only for editing, and authorized users can read the file, but not write any data, meaning that the password for opening is not set. For that reason, only Edit password property should be filled in.

The following directions are available:
In – the argument can only be used within the given project. If the variable is modified inside the workflow, its value is not changed in the main workflow.
Out – the argument can be used to pass data outside of a given project.
In/Out – the arguments can be used both within and outside of a given project.

Wildcards are symbols that enable you to replace zero or multiple characters in a string. These can be quite useful when dealing with dynamically-changing attributes in a selector.
Asterisk (*) – replaces zero or more characters
Question mark (?) – replaces a single character
Invoice 4324 – 2.06.2021.pdf wouldn’t work with Invoice *- ??.??.*.pdf, because it has only 1 character of the day in date, instead of the required 2 characters.

NumberOfRetries property indicates how many times the activity will be executed overall. It is often misunderstood as 1 try + 3 retries (like in Orchestrator queues), however, it actually is simply 3 tries.
Even if Open Browser activity has ContinueOnError property set to True, it doesn’t affect the Retry Scope, because Retry Scope activity has ContinueOnError set to False. So after 3 tries, if the required element still doesn’t exist, the Retry Scope activity will throw an error.

1. Even if the activity is executed as the first one, the robot waits before its execution. By default, for 200 milliseconds, but in this case, the value in DelayBefore is set for 3 seconds.
2. If the corresponding selector cannot be found on the screen, the robot waits by default for 30 seconds for it to appear. If the corresponding selector cannot be found during those 30 seconds, an error is thrown. If ContinueOnError is set to True, then the error is ignored and the error message does not appear. In this case, ContinueOnError is False so the error is thrown.
3.After executing the activity, the robot waits before executing the following activity. By default, for 300 milliseconds, but in this case, the value in DelayAfter is set for 30 seconds.
However, as the corresponding selector is not found, an error is thrown and the robot does not wait for DelayAfter and does not execute the following Delay activity of 7 seconds. Instead, the error is caught as a SelectorNotFoundException and the error exception is displayed with a Message Box.

A background process doesn’t need to interact with UI elements on the screen but rather relies on background processes to pass along information. UIAutomation activities should not be used in these project types. Multiple such processes can simultaneously run on a machine, even if a foreground process is already running.
The type of process is generally dictated by the type of activities it uses (whether or not they interact with UI elements). However, you can specify the type when you create a new process from Studio. By default, all processes are marked as foreground, unless specified otherwise.

Flowchart
A flowchart is a graphical representation of a process in which each step is represented by different symbols connected with arrows.
Flowchart is one of the best among the three layout diagrams of UiPath workflow because it is flexible and tend to lay out a workflow in two-dimensional manner. They can showcase decision points within a process very efficiently owing to their visual appeal.
Sequence
Mostly used layout diagram in UiPath workflow design is sequence. A sequence is a simple linear representation that generally flows from top to bottom, and tells the order in which commands are to be executed.
Sequences are best in simple scenarios when activities pursue each other. The most important thing about sequence is that they are very simple and easy to understand.
State Machine
State machine is a complex structure that stores the status of something at a given point of time. It can be finite or infinite in nature. State machine are represented by using state diagrams or in other words they are flowcharts with conditional arrows called transitions. Structures like state machines are best suited for a standard high-level process diagram of transactional business process templates.

The Internet Message Access Protocol (IMAP) can be used for receiving e-mails, marking them as read or moving them between folders.
