ErrorWithTimeout (Function) Displays a custom error message in a system error window for a set amount of time. After the timeout, the system window is automatically closed. Remarks: - This warning window blocks the application until the time limit has elapsed. To continue running the application, the user must click "OK".
  To avoid blocking the application, use ErrorWithTimeoutAsynchronous. - WINDEV allows you to apply the skin template of your project to this dialog box. For more details, see Customizing dialog boxes.

To customize this dialog box (and all the system dialog boxes in your application), check "Personalizar ventanas del sistema (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, "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 Calling ErrorWithTimeout by specifying only the timeout (syntax2), displays the error message of the last WLanguage function that triggered an error. In this case, the following code: is equivalent to: ErrorWithTimeout(500, ErrorInfo())
Caution: The ErrorWithTimeout function must be used immediately after calling the failed function.. Indeed, calling a WLanguage function may reinitialize and modify the status report of ErrorWithTimeout. - 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: The ErrorWithTimeout is equivalent to function Error used with function DelayBeforeClosing.
The following code:
ErrorWithTimeout(1000, "An error was detected")
DelayBeforeClosing(1000)
Error("An error occurred")
