<h1>Delphi OPC Server Enumerator</h1>
<h3>Introduction</h3>
<p>This document, and the ZIP archive of which it is part, are intended to
illustrate techniques for listing available OPC servers.</p>
<p>The ZIP file contains Delphi source code for a simple OPC client
application.</p>
<p>You will also need the Delphi conversion of the OPC custom interfaces,
available separately from the <a href=
"http://www.opcconnect.com/delphi.php">Delphi page</a> at OPC
Programmers' Connection.</p>
<p>The code has been confirmed to work with Delphi 5.01, 6.02, 7.0 and Delphi
2005 for Win32. On an ongoing basis, it is tested using Delphi 5, 7 and
2005.</p>
<h3>Version History</h3>
<p><b>November 28th 2004:</b> Minor changes for compatibility with Delphi
2005 for Win32.</p>
<p><b>August 29th 2003:</b> Original version.</p>
<h3>File List</h3>
<p>Inside the ZIP archive you will find the following files.</p>
<table border="0" cellspacing="0" cellpadding="0" summary="">
<tr>
<td><b>OPCsrvrs.*</b></td>
<td width="50"> </td>
<td>Main application files</td>
</tr>
<tr>
<td><b>OPCenum.pas</b></td>
<td> </td>
<td>Class which encapsulates methods for enumerating OPC servers</td>
</tr>
<tr>
<td><b>readme-enum.htm</b></td>
<td> </td>
<td>This file</td>
</tr>
</table>
<p>The Pascal source code for the sample application is in OPCsrvrs.dpr.</p>
<h3>Disclaimer</h3>
<p>Although every effort has been made to faithfully convert the original C
and IDL declarations to Object Pascal, and the results have been used and
tested extensively, I can't of course actually <i>guarantee</i> their
correctness. Neither will I be held responsible for any loss or damage
arising from their use.</p>
<p>I would be grateful to know of any problems with these files.</p>
