C++/AS3 winsock send() wont write within else if statment - c++

Question

So, I have a server/client application, at a particular point in the code the client needs to log in to the server, so the server requsts a username and password from the client (and then checks it and blah blah blah)
heres my code,
client side (AS3)
function hwndLogKeyboard(evt:KeyboardEvent):void
{
if (evt.keyCode == 13)
{
var allow:Boolean = false;
var prompt:String;
socket.writeMultiByte("002", "us-ascii");
socket.writeByte(0);
socket.flush();
while (socket.bytesAvailable == 0)
{
trace("waiting for bytes to read");
}
prompt = socket.readMultiByte(2, "us-ascii"); //YOU WERE MISSING ); here originally updated as I was formatting, probably just copy paste error
trace(prompt);
if (prompt == "UN")//server has prompted for username information, time to send it
{
socket.writeMultiByte(inputname.text, "us-ascii");
socket.flush();
prompt = socket.readMultiByte(2, "us-ascii");
if (prompt == "PW")//server has prompted for password information, time to send it
{
socket.writeMultiByte(inputpass.text, "us-ascii");
socket.writeByte(0);
socket.flush();
}
}
//more code in here that i have commented out until this issue is resolved
}
and the server side (where im positive the problem is occuring, writtin in C++)
if(testr >= 0)
{
string dataR = string(buffer);
//data was recived from a client - analize the data to find out what it means
//signals are in the format "xxx" where 'x' is an int between 0-9
if(dataR == "001")
{
cout << "A new client has connected" << endl;
}
else if(dataR == "002")//002 is a client attempting to log-on to the server
{
cout << "Client requesting log-on" << endl;
char recvUsername[16];
const char requestUsername[3] = "UN";
char recvPassword[16];
const char requestPassword[3] = "PW";
send(Client,requestUsername,3,0);//request username from client
recv(Client,recvUsername,16,0);//got username, now time to request password
send(Client,requestPassword,16,0);//request password from client
recv(Client,recvPassword,3,0);//got password, now time to compare them against current records
cout << recvUsername << endl << recPassword << endl;
}
else if(dataR == "003")
{
cout << "A client has used chat" << endl;
}
}
else
{
cout << "error" << endl << testr << endl << WSAGetLastError << endl;
}
At first I thought it was a time issue, that perhaps the client was reading from the buffer before the server can write to it, becuase AS3 crashes becuase the read buffer is empty!
But, here's the trick, I can move my send(Client,requestUsername,3,0) to inside the if(dataR == "001") block, and it works fine. The data IS avalible for flash to read when it goes looking for it. In fact I can put that send statement almost anywhere in my server after the client's socket is created, and it works, just not where i need it to.
That's why i added the
while (socket.bytesAvailable == 0)
{
trace("waiting for bytes to read");
}
in the client, so that it would sit a loop until there was data to read, and if that had been the problem, i would have re-wrote some things to avoid that nasty while loop from having to be there. What I don't understand is that it goes into an infinite loop, flooding me with trace statements. the sever DOESN'T write the data to the socket, but from anywhere else in the code it will. I get no errors, no compiler complaints, it doesn't go out of scope or anything like that, something is just odd here.
help is much appreciated

still having this problem, it works everywhere else in the code except inside the 'else if' block, im completley stumped.
