对话框的实例化，错得莫名其妙解决方法

对话框的实例化，错得莫名其妙
UI中的菜单代码：

C/C++ code

void CTransferSMSAppUi::HandleCommandL(TInt aCommand)    {    switch( aCommand )            {            case EEikCmdExit:            case EAknSoftkeyExit:                Exit();                break;            case ETransferSmsCommand1:                {                iSmsEngine->SocketListen();                                }                break;            case EAdd:                {                form = CDialogContactForm::NewL();  //添加以后提示错误                form->ExecuteLD(R_CONTACTFORM_DIALOG);                                        }            case EDelete:                {                //删除联系人                }            case EAbout:                        {                                                }                        break;            default:                Panic( ETransferSMSUi );                break;            }    }

RSS中的定义
RESOURCE DIALOG r_contactform_dialog
{
flags = EEikDialogFlagNoDrag | EEikDialogFlagFillAppClientRect | EEikDialogFlagWait | EEikDialogFlagCbaButtons; 
buttons = R_AVKON_SOFTKEYS_OPTIONS_BACK;
form = r_contact_form;
}

哪里错了呢？？？？include？？？

纠结了一中午了，还是搞不懂哪里错了~~~~T^T



------解决方案--------------------------------------------------------
Hi,

看上去是链接错误，原因是少库了，修正的方法是在.mmp文件里添加库，比如

LIBRARY eikdlg.lib // CEikDialog

其它的控件/库对应关系可以到SDK帮助文档里查，比如：

"CEikBorderedControl ...Link against: ... eikcoctl.lib"
