copied!<p>Yes, from a service you can run code on the desktop... The matter is on which desktop? because there may be various users logged at the same time (for example in a Windows Server there may be various users logged remotely).</p> <p>If use <code>Process.Start</code> from a service as in your example:</p> <pre><code>System.Diagnostics.Process.Start("www.google.com"); </code></pre> <p>The program will not appear in the desktop of any user, because the service is not associated with any of the desktops of the users.</p> <hr> <p>The solution is to detect which user is logged locally and then execute the program as that user (and under the privileges of that user). For that I want to link you to <a href="https://stackoverflow.com/a/12851218/402022">another of my answers</a> where I demonstrate how to invoke a program from a service. <strong>In <a href="https://stackoverflow.com/a/12851218/402022">that answer</a> I present the code needed for this technique</strong>.</p> <p><em>Note</em>: That answer was about an screen capture, still the technique I describe is to call a program in the session of an user, and that method works from a service. So it applies to your problem.</p> <p>You can use this method to execute the desired browser directly. As an alternative you can use it to invoke your service executable, where you can use <a href="http://msdn.microsoft.com/en-us/library/system.environment.userinteractive.aspx" rel="nofollow noreferrer"><code>System.Environment.UserInteractive</code></a> to detect if the executable is not running as a service or not. If you pass the url as execution argument to your service executable then you can open it with the default browser using <a href="http://msdn.microsoft.com/en-us/library/system.environment.userinteractive.aspx" rel="nofollow noreferrer"><code>Process.Start</code></a> just like your example above.</p> <p><em>Note</em>: The code was tested on Windows 7.</p>
