// You will need the NT SUR Beta 2 SDK or VC 4.2 in order to build this  
// project.  This is because you will need MIDL 3.00.15 or higher and new 
// headers and libs.  If you have VC 4.2 installed, then everything should 
// already be configured correctly. 
 
// 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.   
// 
//Modify the custom build rule for Account.idl by adding the following  
//files to the Outputs.  You can select all of the .IDL files by  
//expanding each project and holding Ctrl while clicking on each of them. 
//Account_p.c 
//dlldata.c 
//To build a separate proxy/stub DLL, 
//run nmake -f Accountps.mak in the project directory.
