Generating VB expressions using a text prompt

Prerequisites

To generate VB expressions using text prompts, your tenant must have sufficient Autopilot actions available.

To generate VB expressions using a text prompt in Autopilot, follow these steps:

Go to the app where you want to add a VB expression.
Note:
- Referring to all controls within a container by the name of the container is not supported. If an expression depends on multiple controls, the prompt must include every control name.
Add a new control or select an existing control.
In the Properties panel**,** select a condition where you wish to add the VB expression. Select the configuration button, then select Open expression editor. The expression editor opens.

When you write a text prompt describing the VB expression you want to add, Autopilot writes the generated VB expression and makes it available for use in the Expression editor text field.

Examples of Autopilot text prompts for VB expressions

Here are a few examples of useful prompts and their use cases.

Apps controls	Intended functionality	Text prompt examples
Input controls	Disables a Submit button if a field is empty.	"If username and password are empty set to true"
App variables	Enables a button if an app variable called "item list" has a length greater than 10.	"If item list length is greater than 10"
Custom objects	Prints a personalized welcome message.	"Concatenate "Welcome" with current user displayname and email id"
Media	Renders a media file you have added to the app.	Simply write the file name: "image_01"
Process	Completes a message with a value from a process.	"Concatenate user billing total amount"
Process and app variables (sorting and filtering)	Assigns a value from a process data table to an app variable data table.	"Sort `process users.datatable` by rating in descending order and filter where name contains john"
Custom function (string addition)	Adds a string to a list called "itemlist".	"Add `firstname` to `itemlist"`
Query parameters	Fetches runtime parameters given to the app in the form of a string. In this case, the time zone and region of a user.	"Concatenate apps timezone and region query parameters"
