Artificially triggers the security mechanism of WLanguage by throwing an exception. Then, this exception can be processed by an exception code written for this purpose. The exceptions are thrown in the WLanguage code only (and not in the framework).
Used in a Webservice, this function allows you to:
  • stop the current process,
  • return an error to the external application that uses the Webservice via the standard SOAP protocol.
    In the XML code returned by the Webservice, the error message is returned in the "faultstring" tag. The error number is not returned in a specific tag, it is contained in the text of the full error details found in the "detail" tag.
    Caution: When consuming this Webservice in a WINDEV, WEBDEV or WINDEV Mobile application, the error must be retrieved by ErrorInfo (and not by ExceptionInfo).
PHP Artificially triggers the PHP security mechanism by throwing an exception.
