Appl Not responding when I use Sockets

[mobileteam]

I am trying to implement TCP sockets in my application, so that our server can push messages to my mobile phone using this sockets. When I execute connect statement to connect to a socket at application server side, I'm able to receive responses. (and I can able to work with the data dynamically.)

But when I tried to select "Options" menu (Using left soft key), It is not opening (sometimes it is taking 2 min. to open). What might be the reason for this one. This is the code I used in my application.

void CTcpSocket::RunL()
{
Receive();
iTimer.After(iStatus,1000000);
SetActive();
}

void CTcpSocket::Receive()
{
iSocket.RecvOneOrMore(iBuffer,0,iSStatus,iLen);
User::WaitForRequest(iSStatus);

if(iSStatus == KErrNone)
{
iRecvBuffer.Copy(iBuffer);
iSynfoTab->dataReceive(iRecvBuffer);
iRecvBuffer.Zero();
}
}

Please help me out.

In the above code I used the code iSynfoTab->dataReceive(iRecvBuffer); to display the received messages on the display screen. Nothing more than that.

I would go and implement the receiving with Active object to get rid of the WaitForRequest(), which can indeed block your application.

[mobileteam]

OK Sure. What will happen if I remove the statement WaitForRequest()? Still I'm calling that method at some particular timer interval. Does it make any sense?

[symbianyucca]

Maybe you should read about the Active objects, there should be quite good amount of documents on the subject.

[mobileteam]

If Active Objects are asynchronous and the requesting functions of Active Object does not block after issuing a request, why the "Options" menu is not working. If it is asynchronous it should support it. Right? Or anything wrong with my understanding.

[symbianyucca]

that because you are not using Active objects correctly, but you are blocking your thread by calling WaitForRequest().

[mobileteam]

could you please help me out in identifying the problem. where exactly I need to change the code.

[symbianyucca]

Remove the WaitForRequest() and implement it as normal Active object, so please do a bit of searching on documents for Active objects and you'll get it working better.

[mobileteam]

If I remove WaitForRequest() method it is able to process single packet arrival, and after it is terminating. I tried it by setting iStatus value to KRequestPending, still the same problem. What are the alternatives for this WaitForRequest().

SetActive is the "alternative". You might consider learning about Active Objects, check post #9 and #10 in http://discussion.forum.nokia.com/fo...d.php?t=133649
