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


Source position: syshelph.inc line 372

public class function TByteHelper.TryParse(

  const AString: string;

  out AValue: Byte



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

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