Interactive service problems

[ati88]

Hello!

I made a Windows Service which logs user activities. There is an option called "Allow service to interact with desktop", and I would like to check this box programatically. I found this page: http://bytes.com/forum/thread258609.html
On that there is a solution, but I got an error on this line:
GetMethodParameters("Change");
The error is: "Not found".
I dont know what should I do to make it work.

Thanks for help!

did you try the follow up code?

Add following class to the cs file that contains the Installer class (class
derived from System.Configuration.Install.Installer).
Change the class ServiceInstaller into ServiceInstallerEx and create an
instance of ServiceInstallerEx instead of ServiceInstaller .
Finally add - using System.Management;

class ServiceInstallerEx : System.ServiceProcess.ServiceInstaller
{
public ServiceInstallerEx() : base()
{
// Set eventhandler to call UpdateServiceConfig when install commited
base.Committed += new InstallEventHandler( this.UpdateServiceConfig );
}
// Eventhandler, called after service installer committed.
// This method uses System.Management classes to change service config.
// Note that enabling "DesktopInteract" will fail if Service account is not
LocalSystem !!
void UpdateServiceConfig(object sender, InstallEventArgs e)
{
int ret;
ManagementBaseObject inParams = null;
ManagementObject srvc = new ManagementObject("Win32_Service=" + "\"" +
this.ServiceName + "\"");
inParams = srvc.GetMethodParameters("Change");
inParams["DesktopInteract"] = true; // Enable interactive mode (Interact
With Desktop)
ManagementBaseObject outParams = srvc.InvokeMethod("Change", inParams,
null);
if((ret = Convert.ToInt32(outParams.Properties["ReturnValue"].Value)) !=
0)
Console.WriteLine("Failed to set option: {0}", ret);
else
Console.WriteLine("Option set");
}
}
