Word Add-in 函数调用顺序

这个图表明的函数的调用顺序，主要代码如下：

  1 // MyAddin.cpp : Implementation of DLL Exports.
  2 
  3 
  4 // Note: Proxy/Stub Information
  5 //      To merge the proxy/stub code into the object DLL, add the file 
  6 //      dlldatax.c to the project.  Make sure precompiled headers 
  7 //      are turned off for this file, and add _MERGE_PROXYSTUB to the 
  8 //      defines for the project.  
  9 //
 10 //      If you are not running WinNT4.0 or Win95 with DCOM, then you
 11 //      need to remove the following define from dlldatax.c
 12 //      #define _WIN32_WINNT 0x0400
 13 //
 14 //      Further, if you are running MIDL without /Oicf switch, you also 
 15 //      need to remove the following define from dlldatax.c.
 16 //      #define USE_STUBLESS_PROXY
 17 //
 18 //      Modify the custom build rule for MyAddin.idl by adding the following 
 19 //      files to the Outputs.
 20 //          MyAddin_p.c
 21 //          dlldata.c
 22 //      To build a separate proxy/stub DLL, 
 23 //      run nmake -f MyAddinps.mk in the project directory.

164     }
165 };
166 
167 #endif //__WORDADDIN_H_

这是两个主要的文件。

注意两个问题：

160         CComBSTR bstr(szRibbon);
161         bstr.CopyTo(RibbonXml);//use this to avoid heap destroy
162         bstr.Empty();
这三行代码是为了防止程序退出时，插件对word的内存进行修改，导致堆错误，Word会Crash。函数的含义请参考MSDN。
