[求助]第一次就失败了！ 无法进行下去了SOS!!!

<P>    安装了MO2.0或MO2.1后,打开某一Samples中的资源文件(含MO控件),即出现</P>
<P>    The Map contains Maplayers which reference invalid datasets.These MapLayers will be removed.</P>
<P>    执行应用程序,不能显示地图.</P>

把控件重新插入一次！！

<P>谢谢olympic0408</P><P>又有新问题了：</P><P> CMoDataConnection conn;
 if (!conn.CreateDispatch(TEXT("MapObjects2.DataConnection")))
  throw "unable to create MapObjects2.DataConnection";
 conn.SetDatabase(GetFileDirectory(path));
 if (!conn.Connect())
  throw "unable to connect to database";
</P><P><FONT style="BACKGROUND-COLOR: #e66b1a"> if (!conn.Connect()) 出错，直接throw "unable to connect to database";
