<p><font face="Arial">Welcome to <strong>MfcCDDB</strong>, a collection of freeware MFC
classes to support access to the <strong>C</strong>ompact <strong>D</strong>isc <strong>D</strong>ata<strong>B</strong>ases
on the Internet.</font></p>
<p><font face="Arial">This document assumes you are already familiar with the CDDB
protocol, if this is not the case then I would strongly advise you to read the CDDB howto
document which you can download from the CDDB web site at <a href="http://www,cddb.org">http://www,cddb.org</a>.
An important point to note is that you will need to get your application verified with
CDDB before you can release your product even when you are using MFCCDDB to connect to
CDDB. Again check on the CDDB web site for more details.</font></p>

<ul>
<li><font color="#000000" size="3" face="Arial">Simple and clean C++ interface.</font></li>
<li><font color="#000000" size="3" face="Arial">The interface provided is synchronous which
provides an easier programming model than using asynchronous sockets.</font></li>
<li><font color="#000000" size="3" face="Arial">The code does not rely on the MFC socket
classes. These classes have a number of shortcomings, one of which causes problems when
they are used in NT services.</font></li>
<li><font color="#000000" size="3" face="Arial">The code can be used in a console
application without any problems (Again this is not the case for the MFC socket classes).</font></li>
<li><font color="#000000" size="3" face="Arial">A configurable timeout for the connection
can be set through the class API.</font></li>

<ul>
<li><font color="#000000" size="3" face="Arial">To use the class in your code simply include
mfccddb.cpp in your project and #include mfccddb.h in which ever of your modules needs to
make calls to the classes.</font></li>
<li><font face="Arial">Your code will need to include MFC either statically or dynamically.</font></li>
<li><font face="Arial">You will need to have a functioning Winsock stack installed and
correctly initialized prior to calling any functions in the CCDDB which access the CDDB
servers. Depending on your application, this will involve calling either WSAStartup or
AfxSocketInit at startup of your application.</font></li>
<li><font face="Arial">You will also need to have winsock.h or afxsock.h in your precompiled
header. The code will work just as well in a GUI or console app. The code should also work
in a multithreaded application, although it has not be explicitly tested in this scenario.</font></li>
<li><font face="Arial">To see the class in action, have a look at the code in InitInstance
in the module "app.cpp".</font></li>
