Socket problem.

I have a simple socket example program. It uses the async method to retrieve data from the socket. But if I change that code in the sync method, I get an error saying the buffer is a null reference...

Here's the project I downloaded don't remember where :)

*** BUMP ***

if u have the async one why would u want to have a sync one?

Because I want to send (receive) a lot of consequential messages:
Send: OPEN
Receive: If Ok then
Send 2nd Mess after OK Mess.
else
Send 2nd Mess after No OK.
and so on...

It's a background job, as long as this procedure is not in the main thread I have no problem with the sync method. But I don't know I to manage this code with the async method...

Any suggestion?
Thx, Xmas.

Made the async method stopping until all data was received... :)
