我的原来也没有，不过后来改了下，就能显示滚动条了。总结如下：
在view的DoActivateL中，如果ListBox创建在AppUi()->AddToStackL( *this, iContainer );前，则滚动条显示不出来，因此，ListBox的创建不能在Container的ConstructL中，或者至少说ScrollBar的创建不能在ConstrucL中。Symbian...

Did you add
SetMopParent(aParent)
when your container construct.

I'm sorry that I'm using C++ as the develop language, I just use simply the recv function that I could get all the data. But it seems that the data is buffered first and so there is a delay.

I'm puzzled at this problem, and today I see there is an KSockWriteUrgent option at the RSocket::Send() function. Perhaps this will work, I guess it only from its literal mean.
