求助VC+MO（关于shp文件保存）

<P>我将mo自带的关于保存打点图层的方法拷贝到我的程序中，运行时出现如下错误：
EasyMapView.obj : error LNK2001: unresolved external symbol "class CString __cdecl GetFileDirectory(class CString const ;)" (<a href="mailt?GetFileDirectory@@YA?AVCString@@ABV1@@Z" target="_blank" >?GetFileDirectory@@YA?AVCString@@ABV1@@Z</A>)

帮我看看啊，为什么值写不进去~
相关程序如下：

<P>MapHelper.cpp,MapHelper.h,MapObjects2.h你加到工程中了吗？用之前再include一下，就应该没问题了</P>

<P>不好意思，上次没仔细看。</P><P>与上边类似的代码我在自己机器上测试过，没问题，如果你确信其余相关代码都没什么问题的话，建议你打一下Visual Studio 6.0 Server Pack6的补丁</P>

<P>编辑之前必须调用EDIT方法。</P>

GetFileDirectory（---）和 GetFileTitle（---）要自己定义的，SetValue（）我的也搞不定，我现在正为这个郁闷呢
