I find the comments in AtlAxWindowProc2 quite confusing. Can you
direct me to any sample code that uses AtlAxWinLicX?

You do something like this:

struct CreateData {
    WORD nCreateSize;
    WORD nMsg;
    DWORD dwLen;
    DWORD cchLicKey;
};
BSTR licKey = ...; // the license key you want to provide
DWORD cchLicKey = SysStringLen(licKey);

WORD size = sizeof(CreateData) + cchLicKey;
BYTE* buf = new BYTE[size];
CreateData* data = reinterpret_cast<CreateData*>(buf);
data.nCreateSize = size;
data.nMsg = 0;
data.dwLen = 0;
data.cchLicKey = cchLicKey;
memcpy(buf + sizeof(CreateData), licKey, cchLicKey * sizeof(OLECHAR));

CreateWindow(CAxWindow2::GetWndClassName(), ..., buf);
delete[] buf;

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
