    CONSOLE APPLICATION : mergebin Project Overview
========================================================================

AppWizard has created this mergebin application for you.  

This file contains a summary of what you will find in each of the files that
make up your mergebin application.


mergebin.vcproj
    This is the main project file for VC++ projects generated using an Application Wizard. 
    It contains information about the version of Visual C++ that generated the file, and 
    information about the platforms, configurations, and project features selected with the
    Application Wizard.

mergebin.cpp
    This is the main application source file.

/////////////////////////////////////////////////////////////////////////////
Other standard files:

StdAfx.h, StdAfx.cpp
    These files are used to build a precompiled header (PCH) file
    named mergebin.pch and a precompiled types file named StdAfx.obj.

/////////////////////////////////////////////////////////////////////////////
Other notes:

AppWizard uses "TODO:" comments to indicate parts of the source code you
should add to or customize.

                       a section block large enough for the managed code.\n \
\n \
The native DLL must have an unused section in it, into which the\n \
.NET assembly will be inserted.  You can do this with the following code:\n \
  #pragma data_seg(\".clr\")\n \
  #pragma comment(linker, \"/SECTION:.clr,ER\")\n \
   char __ph[92316] = {0}; // 92316 is the number of bytes to reserve\n \
  #pragma data_seg()\n \
You would then specify /SECTION:.CLR in the command-line for the location to\n \
insert the .NET assembly.  The number of bytes reserved in the section needs\n \
to be equal to or more than the number of bytes returned by the /I parameter.\n \
\n \
The native DLL must also export a function that calls _CorDllMain in \n \
MSCOREE.DLL.  This function must have the same parameters and calling\n \
conventions as DllMain, and its name must have the word \"CORDLLMAIN\"\n \
in it.\n \
