对话框的实例化，错得莫明其妙

对话框的实例化，错得莫名其妙
UI中的菜单代码：

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;
	        }
	}
