Stored procedures
Displays a custom message in a non-blocking system information window for a given amount of time. After the timeout, the system window is automatically closed.
Remarks:
  • This is a non-blocking error window. The WLanguage code that follows the call to InfoWithTimeoutAsynchronous continues to run. To close the window, the user must validate the OK button or wait for the end of the timeout. When the user clicks "OK", the code of a WLanguage procedure can be run.
  • iPhone/iPad To use this function, you must integrate a custom dialog box into your project. See Customizing dialog boxes for more details.
  • In the WLanguage code following the call to the function, another modal window cannot be opened before closing the dialog box.
Example
// Displays an information window that automatically closes after 10 seconds
InfoWithTimeoutAsynchronous(1000, "Action successful!", MyProcedure_Info)
 
INTERNAL PROCEDURE MyProcedure_Info()
ToastDisplay("Close info")
END

  • The title of the dialog box corresponds to the title of the current window (or page).
    iPhone/iPad To comply with the system specifications, the title of dialog box is empty by default. To define this title, use NextTitle.
  • To modify or define the title of dialog box, use NextTitle.
  • The message is aligned to left.
  • The button caption depends 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 icon displayed (information tooltip) cannot be modified.
iPhone/iPad To use this function, you must customize the dialog boxes in your application. In the project description window, in the "Style" tab, check "Customize the system windows (Info, YesNo, Confirm, Dialog)". See Customizing dialog boxes for more details.

Line break in the dialog box

The CR string (Carriage Return) can be used to force a break to the next line. For example:
InfoWithTimeoutAsynchronous(500, "The form XXX was modified." + CR + "This form will be saved.")
You also have the ability to use the syntax of multiline strings. For example:
InfoWithTimeoutAsynchronous(
[
The XXX form has been modified.
 
This form will be saved.
])
