首先感谢你的指点！
上次那个出现异常的问题，我终于定位错误在从资源中创建LISTBOX的代码上，
但是我还是没有发现错误，所以想再次请教一下。

void CNavboytestContainer::ConstructL(const TRect& aRect)
{
CreateWindowL();
iMainMenuListBox = new (ELeave) CAknSingleStyleListBox( );
TResourceReader reader;
CEikonEnv::Static()->CreateResourceReaderLC(reader, R_NAVBOYTEST_MAINMENU_SINGLE);！！！


我只要一加上这句话（ CEikonEnv::Static()->CreateResourceReaderLC(reader, R_NAVBOYTEST_MAINMENU_SINGLE); ），
重新编译后，运行EMULATOR，就出现异常：双击程序图标后，弹出一个WINDOW 的警告对话框：
“应用程序发生异常unknown software exception (0x80000003),位置在0x6001bb22。
在确定上单击，中止应用程序
在取消上单击，调试应用程序”，但是如果不加上这句话程序就不会出现异常。

以下是我的资源文件：（LISTBOX的资源我加在最后的）

再次感谢你！

another more strange question occurs,i remove all the codes about listbox setup and add code line by line .
it happens that exception occurs if i add "iListBox = new(ELeave) CAknSingleStyleListBox()".
like the following:
弹出一个WINDOW 的警告对话框：
“应用程序发生异常unknown software exception (0x80000003),位置在0x6001bb22。
在确定上单击，中止应用程序
在取消上单击，调试应用程序”，
但是如果不加上这句话程序就不会出现异常。


MORE STRANGE!!!
it bothers me so much!
thank very much!

Hi,

It seems strange to me as well. I cannot see any problems in your code. This is because I cannot see the whole picture of your code. There must be something wrong in other places!!!

I have tried to use your method in my place, and I have constructed a sample code, demonstrating how to contruct a listbox. Should you experience any problems with the code, please let me know. From the code, you can see that I have no problem at all!!!!

For your information, there is a sample code located in the SDK at the following location:

\Symbian\6.1\Series60\Series60Ex\ListBox

I think it provides you a good start to program a listbox control.

Hope this help!
