Asterisk (*) – replaces zero or more characters
Question mark (?) – replaces a single character
we need to replace single character so we can use the ?

1 element is sufficient
Button id or aaname (for identifying the button)

AlterIfDisabled: if enabled, the click action is executed even if the specified UI element is disabled.
CursorMotionType: It specifies the type of motion performed by the mouse cursor. There are two options:
Instant: the cursor jumps to the destination. This is the default option.
Smooth: the cursor moves in increments.

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

5th element in the WIID column means
‘ tableRow=‘5‘ />

“Parital Selector“ means it must be enclosed within Container
“Excel Application Scope“ for Excel Related Activities
“Attach Window“ is the correct answer

Tags
Nodes in the selector XML fragment.
Correspond to a visual element on the screen.
First node is the app window.
Last node is the element itself.
For example:
wnd (window)
html (web page)
ctrl (control)
webctrl (web page control)
java (Java application control)

AnchorPosition – Specifies to which edge of the container the UI element is anchored. The following options are available:
Auto – If selected, the Bottom case is not considered. Searches for the UI element to the left, right or bottom of the container. The closest one is selected. If multiple elements are found at equal distance from the anchor, the target is selected in this order: Right, Left, Bottom.

Dynamic Selector Format

“SimulateType“ sets to “True“
SimulateType doesnt support hot keys
it will type “UiPath[k(enter)]“
In case if you set True to SendWindowMessages
then
it will type “UiPath“

A container that searches for a UI element by using other UI elements as anchors. This should be used when a reliable selector is not available.

Anchor Base – container that searches for a UI element by using other UI elements as anchors. This should be used when a reliable selector is not available.

The AlterIfDisabled Property
The property instructs the target activity whether or not to interact with disabled elements. Please note that this property is only taken into consideration if the SimulateType or SimulateClick are enabled. You can find the AlterIfDisabled property for the following activities:

“same invoice“ means same file 34272.PDF no need to change it
“more fields“ means needs to use variable
{{FieldName}}

WaitForReady – wait for the target to become ready, before performing the activity. There are three available options:
None – does not wait for the target to be ready.
Interactive – waits until only a part of the app is loaded.
Complete – waits for the entire app to be loaded.

KeyModifiers – Enables you to add a key modifier. The following options are available: Alt, Ctrl, Shift, Win.

SimulateClick can only be used with the CLICK_SINGLE and BTN_LEFT input types. Otherwise, an error is thrown when executing a workflow.

ContinueOnError – Specifies if the automation should continue even when the activity throws an error. This field only supports Boolean values (True, False). The default value is False. As a result, if the field is blank and an error is thrown, the execution of the project stops. If the value is set to True, the execution of the project continues regardless of any error.

SendWindowMessages
How does it work?
Replays the window messages that the target application receives when the mouse/keyboard is used.
Clicking and typing occur instantly.
What are the implications?
Works in the background.
Comparable to the Default method in terms of speed.
What are the strong points?
Supports special keys like ‘Enter‘, ‘Tab‘, and other hotkeys
Users can work on other activities during the execution of the automated processes
What are the limitations?
It won‘t be able to erase previously written text automatically.
Works only with applications that respond to Window Messages.
—————————————————
SimulateType
How does it work?
Uses the technology of the target application (the API level) to send instructions.
Clicking and typing occur instantly.
What are the implications?
Works in the background.
Actions are a lot faster, but there are some compatibility limitations.
What are the strong points?
Will automatically erase previously written text.
Users can work on other activities during the execution of the automated processes.
What are the limitations?
Does not support special keys like ‘Enter‘, ‘Tab‘, and other hotkeys
Compatibility is lower than the other two methods

The button shows the status of the selector by checking the validity of the selector definition and the visibility of the target element on the screen.
The Validate button has three states:
 Selector is being validated
 Valid selector
 Invalid selector
 Modified selector, revalidate
The button is correlated with UI Explorer validation states.

Root Node is Highest Level of Node

Activate: if enabled, the specified UI element is brought to foreground and activated before the text is written. If this is not enabled, then the activity will type into the current active window. This property is enabled by default.

Selector can be added into property panel
It is type of “String“
It should be enclosed with double quotes

Default – UiPath proprietary method. Usually works fine with all types of user interfaces.
Active Accessibility – an earlier solution from Microsoft for making apps accessible. It is recommended that you use this option with legacy software, when the Default one does not work.
UI Automation – the improved accessibility model from Microsoft. It is recommended that you use this option with newer apps, when the Default one does not work.

Visually highlights a specified UI element by surrounding it in a box
we can ensure that we selected correct element

For reliability reasons, it is recommended to avoid the usage of the idx attribute in selectors. In such cases, consider adding information about ancestor elements, using relative elements or the Anchor Base activity.

Visual Tree in the Left panel
displays all the nodes of a selector

DelayBetweenKeys – Delay time (in milliseconds) between two keystrokes. The default amount of time is 10 milliseconds. The maximum value is 1000 milliseconds.

Return All Elements Of A Table Using Find All Children Activity

If the ContinueOnError field of an activity inside a Try Catch is set to True, no error is caught when the project is executed.

“idx“ is unreliable selector

Anchor base
This is very useful in cases in which the attribute values are not reliable (are generated at each execution, for example), but there is a UI element that is stable and is linked to the target UI element.
The Anchor Base activity has two parts, one to locate the anchor UI element (like ‘Find Element’), and the second to perform the desired activity

MaxNumberOfResults – The maximum number of results to be extracted. If the value is 0 all the identified elements are added to the output. The default value is 100.

Get Text is output activity

Full selectors:
Contain all the elements needed to identify a UI element, including the top-level window
Generated by the Basic recorder
Recommended when switching between multiple windows
Partial selectors:
Generated by the Desktop recorder
Do not contain information about the top-level window
Activities containing partial selectors are enclosed in a container (Attach Browser or Attach Window) that contains a full selector of the top-level window
Recommended when performing multiple actions in the same window

Because of “ContinueOnError“ Sets to True

KeyModifiers cannot be used with the SendWindowMessages option

“SimulateType“ sets to “True“
SimulateType doesnt support hot keys
it will type “33[k(enter)]“
In case if you set True to SendWindowMessages
then
it will type “33“

Send Window Message Sets to True
That means
It supports Hot Key
[k(enter)]
k means key
enter means enter key from the keyboard

Partial Selector is Best suited for performing multiple actions in the same window.
The best example of using a partial selector would be a simple automation where the deployed workflow only performs actions in the same application without shifting through multiple windows, like a simple CRM.

{{MonthName}} is a field name they used variable so we can use all the month already initialized in the variable name

Contain all the elements needed to identify a UI element, including the top-level window
Generated by the Basic recorder
Recommended when switching between multiple windows

Using wild card character * we can replace
Calendar – Week of May 1, 2017
to
Calendar – * 2017

Don’t contain the tags and attributes of the top-level window, thus the activities with partial selectors must be enclosed in containers.
Generated by the Desktop Recorder.
Best suited for performing multiple actions in the same window.

UI Frameworks – Changes the technology used to determine UI elements and their selectors. The following options are available:
Default – UiPath proprietary method. Usually works fine with all types of user interfaces.
Active Accessibility – an earlier solution from Microsoft for making apps accessible. It is recommended that you use this option with legacy software, when the Default one does not work.
UI Automation – the improved accessibility model from Microsoft. It is recommended that you use this option with newer apps, when the Default one does not work.

idx is unreliable selector
we should avoid it most of the time
but only case if it is dynamic selector
we can use
