<Timeout before closing>: Integer ou Duration

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 (as well as all system dialog boxes of your application), check "Customize the system windows (Info, YesNo, Confirm, Dialog)" in the "Style" tab of the project description. 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:

ErrorWithTimeout(500, "An error was detected while entering the address." + CR + ...
"Please modify the customer details.")

is equivalent to:

ErrorWithTimeout(500, "An error has been detected when entering the address." , ...
"Please modify the customer details.")

You also have the ability to use the syntax of multiline strings. For example:

ErrorWithTimeout(500,
[
An error was detected while entering the address.

Please modify the customer details.
])

Displaying the last error message

Using the ErrorWithTimeout function without any parameters (syntax 2) displays 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, "An error was detected")

is equivalent to:

DelayBeforeClosing(1000)
Error("An error occurred")
