Stored procedures
Displays a custom error message in a non-blocking system error 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 ErrorWithTimeoutAsynchronous 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.
  • In the WLanguage code following the call to the function, another modal window cannot be opened before closing the dialog box.
Example
// Affiche "Une erreur a été détectée" dans une fenêtre d’erreur
// Cette fenêtre d'erreur se fermera automatiquement après 10 secondes
ErrorWithTimeoutAsynchronous(1000, "Une erreur a été détectée")
Syntax
ErrorWithTimeout(<Timeout> , <Text> [, <WLanguage procedure>])
<Timeout>: Integer ou Duration
Amount of time (expressed in hundredth of second) before automatically closing the error window. This parameter can correspond to:
  • an integer corresponding to the number of hundredths of a second,
  • a Duration variable,
  • the duration in a readable format (e.g., 1 s or 10 ms).
<Text>: Character string (with quotes)
Text to display.
<WLanguage procedure>: Name of procedure or lambda procedure, optional
Name of the WLangage procedure ("callback" procedure) called when the user clicks "OK" in the error window.
This WLanguage procedure can correspond to:
  • a name of a global procedure,
  • a name of internal procedure,
  • a lambda procedure.
If this parameter is not specified, no procedure is run when the user clicks "OK" in the error window.
Remarks

Characteristics of dialog box

  • The title of the dialog box corresponds to the title of the current window (or page).
  • 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 (white cross) 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:
ErrorWithTimeoutAsynchronous(500, "Une erreur a été détectée lors de la saisie de l'adresse. " + CR + ...
"Merci de modifier les données concernant le client.")
You also have the ability to use the syntax of multiline strings. For example:
ErrorWithTimeoutAsynchronous(
[
une Erreur À été détectée lors de la Saisie de l'adresse.
 
Merci de modifier les données concernant le client.
])

Miscellaneous

  • Timers (TimerSys) are not stopped when this function is called.
  • The caption of the button is displayed in the language used by Windows on the current computer.
