);

[JScript]
public function LocalCRC(
   Type : IntegrityCheckTypes,
   LocalFile : String
   FileStart : int
   FileLength : int
);

Parameters

Type

Determines type of integrity check algorithm used.

LocalFile

Full path to a file on local system.

FileStart

Integer value that represents starting position in the file for calculating CRC.

FileLength

Integer value that represents length of data in the file where CRC is calculated.

Remarks

LocalCRC method will calculate checksum of local file using any of supported algorithms (CRC, MD5...). For CRC it will be a long value represented in HEX characters (such as ABCDEF01), for MD5 hash it will be 16 HEX numbers (meaning 32 ASCII chars as its readable representation), and for SHA1 it will be 20 HEX numbers. Please note that not many servers support these functions. CRC is most widely supported, so you should use that method if you're unsure how good remote FTP server is.

Requirements

Platforms: Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
