System.InvalidOperationException: An exception occurred in the OnAfterInstall event handler of TestService.WindowsServiceInstaller.
The inner exception System.UnauthorizedAccessException was thrown with the following error message: Cannot write to the registry key..
Winmdows 7 x64
What can i do for that ?

million times better than manually changing the option
|
|
|
|

This did not work for me under WinXP, SP3, VS2010, .NET4.0, however, I found another, working solution at
C# Scheduler[^]
check the comment by corsairX. Worked like a charm!

Use using(RegistryKey cKey = ..) or explicit call cKey.close()
|
|
|
|
|
When i use this code it :
1) Sets key to 272 as desired.
2) in OnStart I try to show a form but it just says it stops the service.
Any clues?

Hi , I do not want read meny posts below. What can I said
the code above was tested under Xp an 64bit 2003 Server and it works.
[RunInstaller(true)]
public partial class ProjectInstaller : Installer
{
protected override void OnAfterInstall(IDictionary savedState)
{
base.OnAfterInstall(savedState);
RegistryKey ckey = Registry.LocalMachine.OpenSubKey(
@"SYSTEM\CurrentControlSet\Services\" + this.serviceInstaller1.ServiceName, true);
if (ckey != null)
{
if (ckey.GetValue("Type") != null)
{
ckey.SetValue("Type", ((int)ckey.GetValue("Type") | 256));
}
}
}
.....
|
|

|

In order to make the sample code work I had to move the modification of the Registry key to the overriden OnCommitted method.
protected override void OnCommitted(IDictionary savedState)
{
base.OnCommitted(savedState);
using (RegistryKey ckey = Registry.LocalMachine.OpenSubKey(@"SYSTEM\CurrentControlSet\Services\My Service", true))
{
if (ckey != null)
{
if (ckey.GetValue("Type") != null)
{
ckey.SetValue("Type", (((int)ckey.GetValue("Type")) | 256));
}
}
}
}

That's little better:
RegistryKey ckey = Registry.LocalMachine.OpenSubKey(
string.Format(@"SYSTEM\CurrentControlSet\Services\{0}", si.ServiceName), true);
|
|
|
|

I've used this code, the check box is successfully set to true but has no effect ?  I still have to go manually change is state, apply and then change is state again, and finally restart the service to make it work.
Can you explain that behavior, anyone had this problem ? I have included most of the installer code, in case you can point out the error somewhere. I have no clue, is there a Commit action missing or anything ?
Thanks folks.

The service controller is out of sync with the registry.
If you reboot, it will resync and work properly, but it sucks as a good solution.
As someone suggested below the 'right way is'
ConnectionOptions coOptions = new ConnectionOptions();
coOptions.Impersonation = ImpersonationLevel.Impersonate;
ManagementScope mgmtScope = new System.Management.ManagementScope(@"root\CIMV2", coOptions);
mgmtScope.Connect();
ManagementObject wmiService;
wmiService = new ManagementObject("Win32_Service.Name='" + ServiceMonitorInstaller.ServiceName + "'");
ManagementBaseObject InParam = wmiService.GetMethodParameters("Change");
InParam["DesktopInteract"] = true;
ManagementBaseObject OutParam = wmiService.InvokeMethod("Change", InParam, null);

You can start and stop your services using this code:
public static class ServiceHelper
{
public static void StartService(string serviceName, int timeoutMilliseconds)
{
ServiceController service = new ServiceController(serviceName);
var servicesDependedOn = service.ServicesDependedOn;
if (null != servicesDependedOn)
{
foreach (var svc in servicesDependedOn)
{
StartService(svc.ServiceName, timeoutMilliseconds);
}
}
try
{
TimeSpan timeout = TimeSpan.FromMilliseconds(timeoutMilliseconds);
service.Start();
service.WaitForStatus(ServiceControllerStatus.Running, timeout);
service.Refresh();
}
catch
{
}
finally
{
service.Dispose();
}
}
public static void StopService(string serviceName, int timeoutMilliseconds)
{
ServiceController service = new ServiceController(serviceName);
var dependentServices = service.DependentServices;
if (null != dependentServices)
{
foreach (var svc in dependentServices)
{
StopService(svc.ServiceName, timeoutMilliseconds);
}
}
try
{
TimeSpan timeout = TimeSpan.FromMilliseconds(timeoutMilliseconds);
service.Start();
service.WaitForStatus(ServiceControllerStatus.Stopped, timeout);
service.Refresh();
}
catch
{
}
finally
{
service.Dispose();
}
}
public static bool IsServiceAvailable(string serviceName)
{
var result = false;
ServiceController service = null;
try
{
service = new ServiceController(serviceName);
result = service.Status == ServiceControllerStatus.Running;
return result;
}
catch
{
return result;
}
finally
{
if (null != service)
{
service.Dispose();
}
}
}
}

The StopService method was wrong, i fixed that:
public static void StartService(string serviceName, int timeoutMilliseconds)
{
ServiceController service = new ServiceController(serviceName);
var servicesDependedOn = service.ServicesDependedOn;
if (null != servicesDependedOn)
{
foreach (var svc in servicesDependedOn)
{
StartService(svc.ServiceName, timeoutMilliseconds);
}
}
try
{
TimeSpan timeout = TimeSpan.FromMilliseconds(timeoutMilliseconds);
if (service.Status != ServiceControllerStatus.Running)
{
service.Start();
service.WaitForStatus(ServiceControllerStatus.Running, timeout);
service.Refresh();
}
}
catch
{
}
finally
{
service.Dispose();
}
}
public static void StopService(string serviceName, int timeoutMilliseconds)
{
ServiceController service = new ServiceController(serviceName);
var dependentServices = service.DependentServices;
if (null != dependentServices)
{
foreach (var svc in dependentServices)
{
StopService(svc.ServiceName, timeoutMilliseconds);
}
}
try
{
TimeSpan timeout = TimeSpan.FromMilliseconds(timeoutMilliseconds);
if (service.Status != ServiceControllerStatus.Stopped)
{
service.Stop();
service.WaitForStatus(ServiceControllerStatus.Stopped, timeout);
service.Refresh();
}
}
catch
{
}
finally
{
service.Dispose();
}
}
public static bool IsServiceAvailable(string serviceName)
{
var result = false;
ServiceController service = null;
try
{
service = new ServiceController(serviceName);
result = service.Status == ServiceControllerStatus.Running;
return result;
}
catch
{
return result;
}
finally
{
if (null != service)
{
service.Dispose();
}
}
}

Hi all,
I'm trying to use this code, and i'm having a problem, i can't make it to work... i have read all posts.
I'm using this code on (ProjectInstaller.VB).
#Region " Component Designer generated code "
Public Sub New()
MyBase.New()
'This call is required by the Component Designer.
InitializeComponent()
'Add any initialization after the InitializeComponent() call
'Add initialization code after the call to InitializeComponent
Dim si As New ServiceProcess.ServiceInstaller
si.ServiceName = "Myapp"
si.DisplayName = "Myapp"
si.StartType = ServiceProcess.ServiceStartMode.Manual
Me.Installers.Add(si)
Dim spi As New ServiceProcess.ServiceProcessInstaller
spi.Account = System.ServiceProcess.ServiceAccount.LocalSystem
spi.Password = Nothing
spi.Username = Nothing
Me.Installers.Add(spi)
Dim ckey As RegistryKey = Registry.LocalMachine.OpenSubKey("SYSTEM\CurrentControlSet\Services\Myapp", True)
If ckey.GetValue("Type") <> Nothing Then
ckey.SetValue("Type", (ckey.GetValue("Type") Or 256))
End If
End Sub
But wend i try to install my service i get this error.
"Unable to create an instance of the "Myapp".ProjectInstaller installer type. --> Exception has been throw by the target of an invocation. --> Object reference not set to an instance of an object."
After this error my installation will rollback.
Cold some one gives a help....
Reagards,
mpires

Tks, i have found the solution....
I have set on after install:
Dim ckey As RegistryKey = Registry.LocalMachine.OpenSubKey("SYSTEM\CurrentControlSet\Services\Myapp", True)
If ckey.GetValue("Type") <> Nothing Then
ckey.SetValue("Type", (ckey.GetValue("Type") Or 256))
End If
And it works....
Nice....

This is a really good article for how to do this in C#.
If, however, you're not using C#, and are using the Platform SDK,
you can simply specify the DesktopInteract mode in the CreateService() API call e.g.:
SC_HANDLE schService = CreateService(schSCManager,
"MyService",
"MyServiceDisplayName",
SERVICE_ALL_ACCESS,
SERVICE_WIN32_OWN_PROCESS | SERVICE_INTERACTIVE_PROCESS,
SERVICE_AUTO_START,
SERVICE_ERROR_NORMAL,
"\"MyQuotedFullPathToExe\"",
NULL, NULL, NULL, NULL, NULL);
Note that in order for the interact mode to function, the service must use the LocalSystem account (second to last parameter = NULL).
Also note that if you set the 'Type' registry value directly to 0x00000110 or similar, this will not work on Windows 2003 server, so the programmatic way is definitely the better bet.
Hope this helps!

See the thread "The right way to do it".
This worked for me. The method in the original post (registry edit) didn't work on my Windows Server 2003 system. Looking at the service properties in the SCM, everything looked fine (the "Allow service to interact with desktop" flag was set), and there were no exceptions thrown in the GUI code, it just wouldn't show anything on the desktop (forms, notify icon, etc.)
Using this method, all worked great.
Regards (and thanks),
Robb

hi,
i tried changing the Registry Key...but my service is not able to run a GUI Application...what is the mistake??.....it is LocalSystem Account and n the properties box , the Desktop Interaction is enabled...
i tried this code,
/***********************code starts here*************************/
Process proc= new Process();
proc.StartInfo.FileName="E:\\MyStarter.exe";
proc.Start();
/***********************code starts here*************************/
what is wrong in my code???
with regards,

This is not working for the application. There is uncheck option available after putting this code.
If any one got the demo application plz post here.

Hello Laurent,
I think this is not the proper solution. Because I felt one thing very interesting i have created on application ..
There this registry chnage us working fine the service is desktop interactive.
But in other application its failing to check the check box option. Event all the code is same.
So i think its better to find some thig good solution.

Absolutely delightful! I had been looking for this piece of code or at least a direction towards doing it myself for sooo long, and finally got it. Though I was quite fine with the registry-'tampering' code, I impelemented it in VB.NET and though the checkbox was set to true for the service, it didn't quite work  I wonder why??
Eventually I used the 'right-way-to-do-it' piece of code and seriously it works like a dream. And moreover I got aware of a whole new concept of altering a service's properties on the fly!
All in all, loved it!

I have a service that I install to run as the "NetworkService" user, instead of the "LocalSystem" user. I tried flipping that bit by hand in the registry and restarting the service, but my console window does not display, like it does when I run as LocalSystem. So I suspect that the bit (just like the dialog box checkbox) only applies if you are running as LocalSystem. Maybe not, but I though I would mention it.

|

So, is there any work around to enable "interact with desktop" for local user account?

I am interested in why this is dangerous. You say "Blake is right of course . . ." but I couldn't find a message from anyone called Blake, or anything about the dangers. Why is this dangerous? Why should it only be used for "quick and dirty". I am writing a "proper" application that will go on sale top the public. Should I not use this method? If not, what is the recommended alternative?

I have written a Windows Service that monitors executing apps and if it isn't able to interact with the desktop the System.Diagnostic.Process.Responding always returns true even if the app has gone "Not Responding". This causes me another problem when the apps are running on another machine I have all sorts of security issues

}
this is the way to do this.
this code was provided by microsoft msdn support for the problem "interact with desktop".
after the installation, you will be able to run a service than can interact with the desktop.
greetings!

I have tried your suggestion.
It gives me an Exception during the installation, but if you do it on different
event - Commited, than it will work.
I absolutely agree that this is the right way of doing it.
Going through the registry -.... is a last reserve.
