to do what.<br>

My project by simple way is :<br>
connect a mic to the sound card , reading the bit stream from the sound card buffer, so that I can handle it ( compress the data and packetize it in a IP form ), Then sending it to the network card ( To a LAN )..<br>
Ofcourse I wanna do this by a less delay because this operation will be continue...<br>
( A Very small Voice Over IP project )<br>
the other side will get the data and unpacketize it and send it to the sound card to get voice in the far end..

NetWalker - have you thought of writing to the h/w vendor (of the sound card) and asking for details from them?<br>

I asked them, But they said I have to use the direct sound commands...<br>
But ( keep it a secret ) I couldn't deal with this coomand before and I don't have any knowledge about how to deal with it from VB ...<br>
If anybody can give me a help.... <br>
( I searched in the msdn Cd's but it gave me nothing about dealing with it from VB )<br>

Sounds like you're attempting VoIP (Voice over IP). This has been done several times already and there are a ton of standards out there already in the arena. If you plan to get into this, hold on to your head, cause there's a ton of stuff out there on this. Here are a few websites that might peek your interest.<br>
<br>
Also, if you're interested in Computer Telephony or Call Centers, there is TeleConnet Magazine and Computer Telephony Magazine. I believe Call Center is still around. I subscribe to the first two, but it's hard for me to keep up with both VB and Computer Telephony. I'm not sure if anyone's written a control to do this or if there is an API available somewhere to do what you're asking. You might be able to get to it using the TAPI driver if you have an MWave type modem. There is plenty of documentation on the TAPI API (Is that redundant?)<br>
