Declaration

Source position: syshelph.inc line 452

public class function TCardinalHelper.TryParse(

  const AString: string;

  out AValue: Cardinal

):Boolean;

Description

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

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