========================================================================

1.03 (beta) 2002-01-11
	File transfer implemented, ICAP_IMAGEFILEFORMAT enabled.
	CAP_INDICATORS implemented.
	Setting the current value of a cap by sending an enum - implemented.
	Bugfix: If DS enabled in No-UI mode, and StartScan fails to transition
	to State 6 (image ready), request to be disabled/closed.

	Passes required tests of Microsoft TwainTst 1.02

1.02 (beta) 2002-01-09
	Bugfix (thanks to Herman Kuiper) - Workaround for illegal
	triplet from Corel Draw and Corel Photopaint, see comment top
	of CapabilityMessage

This project contains a fully functional TWAIN DataSource (DS), ready to
be customized for your device or device family.  To get started, open
the Customization Checklist (.htm or .doc) and proceed down the checklist.

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

/////////////////////////////////////////////////////////////////////////////
Standard files:

GenDS.dsw
    This is the Workspace file - this is what you open in Visual Studio in
	order to work on the DataSource.  It contains information about what
	windows you had open, breakpoints, options, and what project you were
	working on.

GenDS.dsp
    This file (the project file) contains information at the project level and
    is used to build a single project or subproject. Other users can share the
    project (.dsp) file, but they should export the makefiles locally.

GenDS.h
	This is the main header file for the DLL.  It declares the
	CGenDS class, the root object of the DataSource.

GenDS.cpp
	This is the main DLL source file.  It implements the CGenDS class.


GenDS.rc
    This is a listing of all of the Microsoft Windows resources that the
    program uses.  It includes the icons, bitmaps, and cursors that are stored
    in the RES subdirectory.  This file can be directly edited in Microsoft
	Visual C++.

GenDS.clw
    This file contains information used by ClassWizard to edit existing
    classes or add new classes.  ClassWizard also uses this file to store
    information needed to create and edit message maps and dialog data
    maps and to create prototype member functions.

res\GenDS.rc2
    This file contains resources that are not edited by Microsoft 
	Visual C++.  You should place all resources not editable by
	the resource editor in this file.

GenDS.def
    This file contains information about the DLL that must be
    provided to run with Microsoft Windows.  It defines parameters
    such as the name and description of the DLL.  It also exports
	functions from the DLL.

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

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

Resource.h
    This is the standard header file, which defines new resource IDs.
    Microsoft Visual C++ reads and updates this file.

/////////////////////////////////////////////////////////////////////////////
Other GenDS files:

About.h About.cpp
    These files define and implement the 'About box', a subclass of CDialog.
	The layout of this dialog is defined as a resource (IDD_ABOUT).

Capability.h Capability.cpp
	These files define and implement the DS's basic knowledge of TWAIN capabilities,
	such as whether a given capability is settable, what item type it uses,
	what its human-readable name is, etc.

Container.h Container.cpp
	These files define and implement a wrapper for the run-time objects TWAIN
	calls 'containers'.  Basically the values of capabilities are containers.

Dib.h Dib.cpp
	A rudimentary DIB (Device-Independent Bitmap) wrapper.  While it doesn't do
	a lot of fancy stuff, it does provide 'value semantics' for DIBs - meaning
	that CDib's act like numbers and are passed around by value.  Well, if this
	sounds mysterious to you, see Dib.h.
