Does anyone have a 3DES example?

I'm under pressure and am not a C++ expert yet, thus Crypto++ is a bit beyond me for the moment.

DES and AES work as follows (substituting <AES> as the type for the AES version)

if (mode == SatSymCbc)
{
    if (encrypt)
    {
        // establish keys and encrypt
        CBC_Mode<DES>::Encryption cbcEncryption(key, keyLength, iv);
        cbcEncryption.ProcessData(cipherTextR, plainTextX, plaintextLength);
    }
    else
    {
        // establish keys and decrypt
        CBC_Mode<DES>::Decryption cbcDecryption(key, keyLength, iv);
        cbcDecryption.ProcessData(plainTextR, cipherTextX, plaintextLength);
    }
}
else if (mode == SatSymEcb)
etc.

I attempted first to submit type TDES, as I thought I'd come accross that while wading through the code. Didn't recognize it. I assumed it was <DES> with an overloaded function [CBC_Mode<DES>::Encryption cbcEncryption(key1, key2, key3, keyLength, iv);]. It didn't like that either. I'll keep digging through the code but any help would be greatly appreciated.

Thanks in advance.
