s60 2nd通过代码创建cmnet接入点的方法

北京理工大学  20981  陈罡

最近比较忙，没有时间更新blog了，忙里偷闲跑出来冒个泡泡贴点东西。

前段时间贴了关于s60 2nd平台创建cmwap接入点的方法，很多朋友问我如何创建

基于cmnet的接入点，其实基本上是完全一样的，所不同的是需要把proxy设置相关

的地方给去掉即可（我们都是中国移动的“好孩子”）。

使用的时候只需要在CSocketEngine::ConstructL()中加入这个即可。

void CSocketsEngine::ConstructL(TInt down_type)
  {
ChangeStatus(ENotConnected);

// Start a timer
iTimer = CTimeOutTimer::NewL(EPriorityHigh, *this);
CActiveScheduler::Add(this);

// Open channel to Socket Server
if(down_type == HTTP_DOWN_CMNET)
ConnectSmoothCMNET() ;
else
ConnectSmoothCMWAP() ;

// Create socket read and write active objects
iSocketsReader = CSocketsReader::NewL(*this, iSocket);
iSocketsWriter = CSocketsWriter::NewL(*this, iSocket);
  }

这些都是在6670真机上测试过的代码，应该不会有问题。

希望可以帮助到对此还有困扰的朋友，这个是断点续传的测试安装包，有兴趣的朋友可以

实验一下：
