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"
