DatePicker (Function)

In french: DateSélecteur

Opens the system date picker.

Note To select a date using the date picker, we recommend using the "Date roll" input mask directly for the "Date" edit control. This input mask is also available for iPhone/iPad applications.

Example

d is Date = DatePicker()

DateInitiale is Date = "20170101"
MaDate is Date
MaDate = DatePicker(DateInitiale, "Date de départ")

Syntax

<Result> = DatePicker([<Initial date> [, <Title>]])

<Result>: Date or Character string

Date selected in the picker,
Empty string ("") if the selection was canceled by the user.

<Initial date>: Date or optional character string

Date displayed when opening up the picker. If this date is not specified the picker will display the current date.

<Title>: Optional character string

Title that must be displayed in the picker. If this parameter is not specified, the title will be the date displayed in the picker in text format.

Remarks

Application in the background: Specific case from Android 10

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

DatePicker 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.
