C# Get Application name "Last Message: No "result" or "error" in XML response."

Could you post the actual the actual output when using the for loop? Additionally, check out String.Format, it allows you to replace placeholders in strings which will actually make your code much more readable :)

Hi, this is the output, please check it. Thanks. : D

<?xml version="1.0" encoding="UTF-8" ?>
<prtg>
   <result>
     <channel>Internet Information Services (IIS) 管理員</channel>
     <unit>Custom</unit>
     <value>0</value>
   </result>
   <result>
     <channel>file:///c:/users/administrator/documents/visual studio 2012/Projects/ConsoleApplication2/ConsoleApplication2/bin/Debug/ConsoleApplication2.EXE</channel>
     <unit>Custom</unit>
     <value>0</value>
   </result>
   <result>
     <channel>ConsoleApplication2 [執行] - Microsoft Visual Studio (系統管理員)</channel>
     <unit>Custom</unit>
     <value>0</value>
   </result>
  </prtg>

The output actually works in PRTG...anything else after the output in the console? Does the application need special permissions?

Hi, there is nothing else after the output in the console, no special permission. Here is the whole code. Thanks.

using System;
using System.Diagnostics;
using System.IO;
using System.Collections.Generic;
using System.Linq;
using System.Text;


class ConsoleApplication2
{
   public static void Main()
   {
       Process[] processlist = Process.GetProcesses();
       Console.WriteLine(@"<?xml version=""1.0"" encoding=""UTF-8"" ?>");
       Console.WriteLine(@"<prtg>");
       foreach (Process process in processlist)
       {
           if (!String.IsNullOrEmpty(process.MainWindowTitle))
           {
               Console.WriteLine("   " + @"<result>");
               Console.WriteLine("     " + @"<channel>" + process.MainWindowTitle + "</channel>");
               Console.WriteLine("     " + @"<unit>" + "Custom" + "</unit>");
               Console.WriteLine("     " + @"<value>" + "0" + "</value>");
               Console.WriteLine("   " + @"</result>");
           }
       }
       Console.WriteLine("  </prtg>");
      
   }
}

What values are you actually trying to read out with that sensor? Just asking, because the Windows Process sensor might be what you're looking for. Other than that, the code looks fine... Did you try to change the sensor settings so it's execute within a different user context (Security Settings in the settings tab)?

I want to read the "application name" in task manager tab, just want to know what is running in server.

I found the application name is always null ! but i run it on local, it is ok did you solve it ?

As mentioned, did you try to change the sensor settings so it's executed within a different user context (Security Settings in the settings tab of the sensor)?

Kind regards, Stephan Linke

Yes, but it still not work. could u show me the example to list the desktop application name?

Are you actually using the user that has the applications opened? This may possibly not work at all due to the different sessions used by Windows in the background.

Kind regards,
