There's a function in the Windows crypt32.dll library to do it: CryptBinaryToString[^]

Sql native client should do, install it and look for examples. OLEDB and ODBC providers are good as well, look here http://msdn.microsoft.com/en-us/library/ms130809.aspx

Much apreciated guys for your contributions. Thanks, Garyc
