// GraphObj.cpp : Implementation of DLL Exports. 
 
 
// Note: Proxy/Stub Information 
//To merge the proxy/stub code into the object DLL, add the file  
//dlldatax.c to the project.  Make sure precompiled headers  
//are turned off for this file, and add _MERGE_PROXYSTUB to the  
//defines for the project.   
// 
//If you are not running WinNT4.0 or Win95 with DCOM, then you 
//need to remove the following define from dlldatax.c 
//#define _WIN32_WINNT 0x0400 
// 
//Further, if you are running MIDL without /Oicf switch, you also  
//need to remove the following define from dlldatax.c. 
//#define USE_STUBLESS_PROXY 
// 
//Modify the custom build rule for GraphObj.idl by adding the following  
//files to the Outputs. 
//GraphObj_p.c 
//dlldata.c 
//To build a separate proxy/stub DLL,  
//run nmake -f GraphObjps.mk in the project directory.
