question about setting IV

[SP]

I would like to explicitly set the IV. I think this is what I need to
do. Can someone verify?

var name : String = "aes" + "-" + "cbc";
var pad : IPad = new PKCS5();
var mode : ICipher = Crypto.getCipher(name, key, pad);

(IVMode (mode)).IV = "the IV bytes";

pad.setBlockSize(mode.getBlockSize());
mode.encrypt(data);
