Do not use RcvdCount and do not peak into data. Simply receive data into a buffer having the size of your record. Have a variable with the count of already received byte. Of course you initialize this variable to 0. Then when onDataAvailable call Receive, passing the buffer pointer incremented by the count of already received bytes and the length of the buffer minus the already received byte count. Receive will return the length of data received (or -1 in that case you simply ignore it, or 0 meaning the remote has properly closed the connection). Add this received data length to your received byte count. If the sum less than the record size, then do nothing more since data will come by itself in the next dataavailable. If the count is equal to the record size, then you have your record. Clear the received byte count and do whatever is needed once you have your record. If the count is greater than the record size, then you have a bug. The actual code is probably smaller than my explanation :-) Contribute to the SSL Effort.
