# TInt64Helper.TryParse

Try to convert a string to a Int64, report success or failure

## Declaration

Source position: syshelph.inc line 543

`public class function TInt64Helper.TryParse(`
`const AString: string;`
`out AValue: Int64`
`):Boolean;`

## Description

TryParse attempts to convert the string AString to a Int64, and reports the success of the attempt. If the attempt is successful, then True is returned, and the actual value of the Int64 is returned in AValue.

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