Syntax

Displaying a custom error message Hide the details

ErrorWithTimeout(<Timeout> , <Text> [, <Line 2> [... [, <Line n>]]])
<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,
  • Versions 23 and later
    the duration in a readable format (e.g., 1 s or 10 ms).
    New in version 23
    the duration in a readable format (e.g., 1 s or 10 ms).
    the duration in a readable format (e.g., 1 s or 10 ms).
<Text>: Character string (with quotes)
Text to display.
<Line 2>: Optional character strings (with quotes)
Text displayed on the following lines.
<Line n>: Optional character strings (with quotes)
Text displayed on the following lines.

Displaying the error message of the last WLanguage function used Hide the details

ErrorWithTimeout(<Timeout before closing>)
<Timeout before closing>: 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,
  • Versions 23 and later
    the duration in a readable format (e.g., 1 s or 10 ms).
    New in version 23
    the duration in a readable format (e.g., 1 s or 10 ms).
    the duration in a readable format (e.g., 1 s or 10 ms).
Remarks

Characteristics of dialog box

  • The title of dialog box corresponds to the title of current window. To modify this title, 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.
To customize this dialog box (and all the system dialog boxes in your application), check "Customize the system windows (Info, YesNo, Confirm, Dialog)" in the "Style" tab of the project description. For more details, see Customizing dialog boxes.

Line break in the dialog box

The CR string (Carriage Return) can be used to force a break to the next line. For example:
ErrorWithTimeout(500, "Une erreur a été détectée lors de la saisie de l'adresse. " + CR + ...
"Merci de modifier les données concernant le client.")

is equivalent to:
ErrorWithTimeout(500, "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:
ErrorWithTimeout(500,
[
une Erreur À été détectée lors de la Saisie de l'adresse.
 
Merci de modifier les données concernant le client.
])

Displaying the last error message

Using function ErrorWithTimeout by specifying only delay (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:
ErrorWithTimeout(500)

is equivalent to:
ErrorWithTimeout(500, ErrorInfo())
Caution: ErrorWithTimeout must be used immediately after the call to the function that failed. Indeed, calling a WLanguage function may re-initialize and modify the status report of ErrorWithTimeout.

Miscellaneous

  • Timers (TimerSys) are not stopped when this function is called.
  • Windows events 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.
  • Equivalence: ErrorWithTimeout is equivalent to Error used with DelayBeforeClosing:
    The following code:
    ErrorWithTimeout(1000, "Une erreur a été détectée")

    is equivalent to:
    DelayBeforeClosing(1000)
    Error("Une erreur a été détectée")
Component: wd260obj.dll
