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:
Error("Une erreur a été détectée lors de la saisie de l'adresse. " + CR + ...
"Merci de modifier les données concernant le client.")

is equivalent to:
Error("Une erreur a été détectée lors de la saisie de l'adresse. ", ...
"Merci de modifier les données concernant le client.")
You also have the ability to use the syntax of multiline strings. For example:
Error(
[
une Erreur À été détectée lors de la Saisie de l'adresse.
 
Merci de modifier les données concernant le client.
])
Reports and QueriesJavaUser code (UMC)Ajax

Displaying the last error message

Using the Error function without any parameters (syntax 2) allows you to directly display the error message corresponding to the last WLanguage function that triggered an error.
In this case, the following code:
Error()
is equivalent to:
Error(ErrorInfo())
Caution: Error must be used immediately after the call to the function that failed. Indeed, the call to a WLanguage function can reinitialize and modify the error report returned by Error.

Miscellaneous

  • Timers (TimerSys) are not stopped when this function is called.
  • Java The DelayBeforeClosing function limits the display time of all dialog boxes. The dialog box is automatically closed. For question or confirmation dialog boxes, the default button corresponds to the expected answer.
  • The caption of the button is displayed in the language used by Windows on the current computer.
