Try to convert a string to a QWord, report success or failure


Source position: syshelph.inc line 568

public class function TQWordHelper.TryParse(

  const AString: string;

  out AValue: QWord



TryParse attempts to convert the string AString to a QWord, and reports the success of the attempt. If the attempt is successful, then True is returned, and the actual value of the QWord is returned in AValue.

It uses the val function to perform the conversion, so no localization is taken into account.
