	online Example 9-3	In Example 9-3, the sample program "Get-Characteristics.ps1", there is a line where the offset for the PE signature is being read: ## The offset of the signature in the file is stored at location 0x3c. $signatureOffset = $fileBytes[0x3c] Instead of being a single byte, this value is a 4-byte integer, and so it needs to be read this way: $signatureOffset = [BitConverter]::ToInt32($fileBytes, 0x3c) (I'm not positive that the value is a signed integer, it may be unsigned, in which case the ToUInt32() method would need to be used.)

Printed	Page 461 Exaple 18-4	The example tests if the credential exists in memory, but then goes ahead and prompts for the credential regardless. This script is missing an else statement -- it should only prompt if it doesn't exist.	Charlie Russel (Microsoft MVP)	Mar 11, 2013
