其实在我看来，symbian OS之上的MMI编程和MFC类似，都是有个application framework，用户需要的就是在这个基础之上，对类进行继承，对函数进行重载，而framework完成了很多和系统进行交互的工作。
This is the second document . on my opinion, there are same a little between MFC and symbian OS .They all own a application framework on their basic OS. Based on such framework, user only need to make their own derived class ,and reload the virtual functions. and the framework can help u hanle most work interacting with the OS.

这是文档中关于编译和运行的资料，我懒得翻译了。还有结合我开发中的问题
做了补充。

1. abld是利用项目文件（appname.mmp)进行编译的，所以，在你的mmp文件改动过后，一定要利用
abld makefile vc6
重新生成VC工程文件，然后才能够利用VC进行app的编译，否则会出错。
(手工修改VC的编译、连接设置不起作用，不知为何？）
一、编译和运行
1. Building and running the examples
This section explains how to build and run the SDK example applications. All the applications are built and run in the same way. The applications can be built to run on the Symbian OS emulator, or the target device.
2. Building for the Symbian OS emulator
The SDK and the example applications should be installed.
To build an application, do the following:
1. Create the abld file.
In a command window, go into the application''''s top level folder (the one which contains the bld.inf file) e.g. \animation\gui\group and enter the following command:
bldmake bldfiles
This will create the abld.bat file in the current directory.
2. Create the Wins build files and build the application.
In the application''''s top level folder enter the following command:
abld build wins udeb
This will create the necessary build files and build the application, including any resource files required. This stage may produce warnings. If it produces errors, a DLL component may not have had its exports frozen. Perform step 3, below.
