Sending data using Sockets

[amitaggarwal]

What is the process of sending data using Sockets .

I have made a connection using Socket.Connect()

Now what to do after this ..
Becase when i do something like

if(iRunState==ESocketConnected)
{
iSocket.Write(aDesc,iStatus);
SetActive();
iRunState=ECommandSent;
}

The program crashes......

what is the error note shown during the crash ?

Also is the aDesc a member variable of the class ?, it should really be, since othervise it could go out-of-scope during the write process.

oho ..
It is not the member of the class .
I m just passing it as a perimeter in a function .
Okie .. i wil make it a member of the class now .

Hi Yucca now i have made it a member of the class and this is the latest situation ....


this is the code ..........

Code:

//in Connect Function
// Connect to the server, asynchronously
iSocket.Connect( iInetAddr, iStatus );
SetActive();



//in RunL()
Code:

void CConnection::RunL()
{
switch ( iRunState )
{
case ESocketConnected:
//User::LeaveIfError(iStatus.Int());// leave on bad return code
if(iStatus==KErrNone)
{
iRunState=ESocketConnected;
_LIT(KSocketConnnectedMessage, "Socket Connected");
CEikonEnv::Static()->AlertWin(KSocketConnnectedMessage);

}
break;



and in Send data ffunction
Code:

void CConnection::Send(const TDesC8& aDesc)
{
iSndBuffer=aDesc;
if(iRunState==ESocketConnected)
{
iSocket.Write(iSndBuffer,iStatus);
SetActive(); .\\Leaves here .......
iRunState=ECommandSent;
}
}

also when i reach the line setActive the connection has not been made.
As i m testing it on a java server where it shows when connected.
But when i m checking iRunState==ESocketConnected
how is it possible that without making the connection it executes the "iSocket.Write(iSndBuffer,iStatus);"
