       QS-Barcode SDK Version 4.7 DEMO VERSION FOR EVALUATION
======================================================================

----------------------------------------------------------------------
Installation details
----------------------------------------------------------------------
1. Unpack the ZIP archive, e.g. using the software "WinZip"
2. Install QS-Barcode SDK on the development PC by running 
   SETUP.EXE.

----------------------------------------------------------------------
Update details
----------------------------------------------------------------------
If you plan to update to version 4.7 from earlier versions, please 
note the following:

1. programming interfaces
The interfaces of 4.6 and 4.7 are the same, there is no need to 
change your code calling the QS-Barcode SDK functions.
However, if you have linked the SDK using one of the LIBs, you will 
have to re-link with the new version of the LIB.

As QS-Barcode SDK now uses the CRT functions which are buffer 
overflow protected, binding with very old CRT versions in not 
possible anymore. We have seen this with Visual Studio 6.0 
environments.

If you are updating from version 4.5 or older, have a look at the 
new interfaces introduced in version 4.6.
See chapter 14.4 Update Notes (page 51) in the SDK documentation 
for details.

2. Redistributable files
The list of files is the same for 4.6 und 4.7 (of course the files 
are newer ones). 

It might be necessary to install to "Microsoft Visual C++ 2008 
Redistributable (SP1)" package. Download the latest version at the 
Microsoft webpage.

The redistributable files for each interface are listed in the SDK 
documentation (chapters named "Redistributable Files").

3. DataMatrix Recognition - Changes

Version 4.7 introduces a new feature for DataMatrix recognition.
It is now possible to turn on and off a set of search mechanisms 
which are only necessary for low quality images.
If these mechanisms are turned off this increases the recognition 
speed. By default they are turned off.
Have a look at Chapter "Special Settings for Data Matrix Codes" in 
the SDK documentation to learn more about "intensive search". 


4. ActiveX OCX - Changes

There is one new method and two new properties added to the OCX interface.
Please check if it is necessary for you to change anything to take this 
into account. If you do not want to use the new features, no source code 
changes in your calling routines are necessary.
Learn more about the new features in the SDK documentation.

Evaluation version details

The evaluation version has all the features of the full version, 
except: 
- The resulting barcode data will be slightly patched, some 
  characters are changed (character 3->1, aA->qQ, bB->sS).
- 2D barcodes will have the text -demo- in the result.

The evaluation version can be used to complete entire programming and 
integration into your software.
