The source code of this application can be compiled for 32-bit Windows (as console application) as well as for 16-bit small-model DOS targets. When run more than once, i.e. with an existing datafile, this program will cause some changes to the data which illustrate the effects of "on-the-fly data restrcuturing". Demo has little practical use, other than to show you how to get started with Metakit. </p> <p><b>How to use it</b>: When you launch the 16-bit DOS version called DEMO16.EXE, it creates a datafile called "myfile.dat", saves some data to it, and then reopens it and displays the line: <pre> The country of Paco Pena is: Spain </pre> By following the code, you can see where this came from. You can use the Metakit dump utility (see below) to examine the contents of the data file. <p><b>Known problems</b>: None.</p> <p><b>Files in EXAMPLES\DEMO</b>: </p> <p>DEMO.CPP - Demo main program <br>DEMO.MAK, DEMO.MDP - MSVC 4.2 project makefiles for Win32 <br>DEMO16.MAK - MSVC 1.52 project makefile <!--end--> <center><p><hr size=1> || <a href="index.html" target="_top">Roadmap</a> <a href="classes.html">Class Index</a> <a href="samples.html">Sample Index</a> || <a href="intro.html">Introduction</a> <a href="tips.html">Tips and Tricks</a> || </center> </font> </body></html>
