// Direct.cpp : Implementation of DLL Exports.

// To fully complete this project follow these steps

// You will need the new MIDL compiler to build this project.  Additionally,
// if you are building the proxy stub DLL, you will need new headers and libs.

// 1) Add a custom build step to Direct.idl
//		You can select all of the .IDL files by holding Ctrl and clicking on
//		each of them.
//
//		Description
//			Running MIDL
//		Build Command(s)
//			midl Direct.idl
//		Outputs 
//			Direct.tlb
//			Direct.h
//			Direct_i.c
//
// NOTE: You must use the MIDL compiler from NT 4.0,
// preferably 3.00.15 or greater
//
// 2) Add a custom build step to the project to register the DLL
//		For this, you can select all projects at once
//		Description
//			Registering OLE Server...
//		Build Command(s)
//			regsvr32 /s /c "$(TargetPath)"
//			echo regsvr32 exec. time > "$(OutDir)\regsvr32.trg"
//		Outputs
//			$(OutDir)\regsvr32.trg

// 3) To add UNICODE support, follow these steps
//		Select Build|Configurations...
//		Press Add...
//		Change the configuration name to Unicode Release
//		Change the "Copy Settings From" combo to Direct - Win32 Release
//		Press OK
//		Press Add...
//		Change the configuration name to Unicode Debug
//		Change the "Copy Settings From" combo to Direct - Win32 Debug
//		Press OK
//		Press "Close"
//		Select Build|Settings...
//		Select the two UNICODE projects and press the C++ tab.
//		Select the "General" category
//		Add _UNICODE to the Preprocessor definitions
//		Select the Unicode Debug project
//		Press the "General" tab
//		Specify DebugU for the intermediate and output directories
//		Select the Unicode Release project
//		Press the "General" tab
//		Specify ReleaseU for the intermediate and output directories

// 4) Proxy stub DLL
//		To build a separate proxy/stub DLL,
//		run nmake -f ps.mak in the project directory.
