To modify or define the title of dialog box, use NextTitle.

The message is aligned to left.
The captions of buttons depend on the runtime language of Windows.
The maximum number of characters cannot exceed 4096. If a larger string is passed in parameter, it will be truncated.
The entire string is displayed, regardless of its size.
The icon displayed (information tooltip) cannot be modified.

Line break in the dialog box

The CR string (Carriage Return) can be used to force a break to the next line. For example:

Info("The XXX form was modified." + CR + "This form will be saved.")

is equivalent to:

Info("The XXX form was modified.", "This form will be saved.")

You also have the ability to use the syntax of multiline strings. For example:

Info(
[
The XXX form has been modified.

This form will be saved.
])

Application in the background: Specific case from Android 10

From Android 10, it is no longer possible to open a window when the application is in the background.

Info can open a window. If this function is used while the application is in the background, a fatal error will occur.

Tips:

It is possible to determine if the application is in the background using InBackgroundMode.
If an application needs to interact with the user while it is in the background, the solution is to display a notification (via the Notification type). The application will be brought back to the foreground when the notification is clicked, if the ActivateApplication property is set to True. You can also open a window from the procedure passed to the ActionClick property.

See Android 10: Behavior of applications in the background for more details.
