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:
