请教esricore.tlh文件是怎么产生的？VC+AO

还没有用VC写过ao的程序，看了gis兄的东东，由于不能运行，现在茫然不知如何开始写AO+VC的代码？请GIs或其他VC＋AO的有经验者指导谢谢。

<P>咳，主要还是 侬的 COM 技术水平不过关， 哈哈。</P><P>学好ArcGIS 开发  只要 2个                     COM 技术+ AO 对象模型。</P><P>当然还要有对业务的了解。</P>

*.tlh 是在gis接口调用中vc自动生成的，在一个IWorkspaceFactory上使用find the definition 就可以进入这个文件，定义了com的接口标识。这个文件不用关心。它不影响程序的运行。

一直用VB在开发AO，一天为了测试一个功能用C＃写了一段代码，我的天那个艰难啊，当年C的东西全记不得了，呵呵！语言的学习永不止境，啥时候才能真正提高到一个高度哦！

仅仅是讨了一个说法，其他仍无进展。头痛啊。

<P>哈。。</P><P>祝贺。</P>

<P>The main use of #import is to create C++ code for interface definitions, GUID constants (LIBID, CLSID and IID) and define smart pointers. The exclude ("OLE_COLOR", "OLE_HANDLE", "VARTYPE") is required because Windows defines these to be unsigned longs, which conflicts with the ArcGIS definition of long梩his was required to support Visual Basic as a client of ArcObjects, since Visual Basic has no support for unsigned types. There are no issues with excluding these.</P><P>You can view the code generated by #import in the ".tlh" files (type library header file - similar format to a .h). You may also find a ".tli" file (type library implementation - corresponds to .cpp). These files can be large but are only regenerated when the type libraries change.</P><img src="images/post/smile/dvbbs/em08.gif" />

谢谢。

<P>你在esri 论坛里搜索 esricore.tlh ，很找到大概7个吧</P>
