copied!<p>There are at least two ways: one of these is the 'right' way, and one is 'wrong' (but works.)</p> <h2>The wrong-but-works way</h2> <p>You can run any application as a service through (host) helper utilities, such as:</p> <ul> <li><a href="http://serviceex.com/" rel="noreferrer">ServiceEx</a>, "a freeware Windows application that allows a normal program to run as a Windows service". I have never used this, I just found it through Googling.</li> <li><a href="http://support.microsoft.com/kb/137890" rel="noreferrer">One of two utilities Microsoft provides</a> (Since it's from MS, I would use this one.)</li> </ul> <p>Why is this the wrong way? Because if you want your application to run as a service, you should create a service app. And it just so happens that that's very easy with Delphi. This is the right way:</p> <h2>The right way: create a service app</h2> <p><a href="http://delphi.about.com/od/windowsshellapi/a/delphi-windows-service-applications.htm" rel="noreferrer">This delphi.about.com article has a lot of information about service applications</a>. However, it's fairly simple: create a new service application through File > New > [perhaps Other >] Service Application. Set the display name etc. To install it, run with the command line switch <code>/install</code>; to uninstall run with <code>/uninstall</code>.</p> <p>If the reason you want your command-line app to run as a service is because you don't want to write two applications, with good design you can minimise the extra work. In your project group have two applications, your command-line app and your service app. Then share the code in other files - i.e. write the code to do your app's work once, and include / call it from both projects.</p>
