Does anyone know how to send and retrieve a packet to a Battle.net server using vb code? im not sure whether to use a TCP Client or a UDP Client, or something completely different.

Any information would be greatly appreciated.

I've tried using BNETDocs but maybe i'm sending the message the wrong way? I've tried sending "0x50" for the cd key check also tried sending "SID_AUTH_..." with no response. Am I supposed to append values to the message? and if so, how would I go about doing so?

Thanks in advance!
