//通过监听短信接受套接字，在socket处实现拦截接受短信，可是出现了一下两个问题，请侠客帮忙解决！
//第一个问题是if(BindErr == KErrNone)语句内部没有执行，
//第二个问题是程序到iSmsMessage->InternalizeL(readStream)时退出。
void CSMSEngine::SocketListen()
{
_LIT(KTag, "#");
TBuf8<2> matchTag;
matchTag.Copy(KTag);
iSocketServer.Connnect();
TInt err = iSocket.Open(iSocketServer, KSMSAddrFamily, KSockDatagram, KSMSDatagramProtocol);
if(err==KErrNone)
{
TRequestStatus iStatus;
TSmsAddr smsaddr;
smsaddr.SetSmsAddrFamily(ESmsAddrMatchText);
smsaddr.SetTextMatch(matchTag);
TInt BindErr = iSocket.Bind(smsaddr);
//为什么没有成功绑定呢？通过写日志的发现程序走不进下面的if语句啊！
if(BindErr == KErrNone)
{
iPckgBuf() = KSockSelectRead;
//Applies an asynchronous I/O control operation on a socket.
iSocket.Ioctl( KIOctlSelect,iStatus, &iPckgBuf, KSOLSocket);
iRead=ETrue;
SetActive();
}
}
}

// -----------------------------------------------------------------------------
// CSMSEngine::RunL()
// Gets hit everytime a message with the 'tag' arrives
// -----------------------------------------------------------------------------
//当把上面if(err==KErrNone)注释掉时，可以使得程序走到RunL();但是通过日志发现程序
//只能走到iSmsMessage->InternalizeL(readStream)之前，
void CSMSEngine::RunL()
{
if(iRead)
{
CSmsBuffer *smsBuffer = CSmsBuffer::NewL();
CleanupStack::PushL(smsBuffer);
RSmsSocketReadStream readStream(iSocket);
iSmsMessage = CSmsMessage::NewL(iFs,CSmsPDU::ESmsDeliver,smsBuffer);
iSmsMessage->InternalizeL(readStream);
//这一句好像也不能执行，为什么吗啊？
readStream.Close();
iSmsMessage->Buffer().Extract(iBuf,0,iSmsMessage->Buffer().Length());
iSocket.Ioctl( KIoctlReadMessageSucceeded,iStatus, &iPckgBuf, KSolSmsProv);
CAknInformationNote* note122=new(ELeave) CAknInformationNote;
note122->ExecuteLD(iBuf);
iRead=EFalse;
SetActive();
CleanupStack::PopAndDestroy(smsBuffer);
}
}
