Various Classes Available in .NET to Deal with Windows Services

The System.ServiceProcess namespace provides classes that allow you to implement, install, and control Windows service applications. The various classes available within this namespace are:

Classes

Class

Description

ServiceBase

Provides a base class for a service that will exist as part of a service application. ServiceBase must be derived when creating a new service class.

ServiceController

Represents a Windows service and allows you to connect to a running or stopped service, manipulate it, or get information about it.

ServiceControllerPermission

Allows control of code access security permissions for service controllers.

ServiceControllerPermissionAttribute

Allows declarative service controller permission checks.

ServiceControllerPermissionEntry

Defines the smallest unit of a code access security permission that is set for a ServiceController.

ServiceControllerPermissionEntryCollection

Contains a strongly-typed collection of ServiceControllerPermissionEntry objects.

ServiceInstaller

Installs a class that extends ServiceBase to implement a service. This class is called by the install utility when installing a service application.

ServiceProcessDescriptionAttribute

Specifies a description for a property or event.

ServiceProcessInstaller

Installs an executable containing classes that extend ServiceBase. This class is called by installation utilities, such as InstallUtil.exe, when installing a service application.

TimeoutException

The exception that is thrown when a specified timeout has expired.

Enumerations

Enumeration

Description

PowerBroadcastStatus

Indicates the system's power status.

ServiceAccount

Specifies a service's security context, which defines its logon type.

ServiceControllerPermissionAccess

Defines access levels used by ServiceController permission classes.

ServiceControllerStatus

Indicates the current state of the service.

ServiceStartMode

Indicates the start mode of the service.

ServiceType

Represents the type of the service.

Conclusion

By taking advantage of the Framework Base Classes, the complexity needed to create a service is greatly reduced. This lets the developer to concentrate more on the functionality of the service instead of spending time in creating it.

Title: How do we programmatically configure a Windows Service to interact with the desktop?

Hello,
Can u please let me know how do I make the windows service interact with the desktop since the windows service has to invoke a windows application upon its successful start?
Please let me know where exactly a property called "AllowServiceToInteractWithDesktop" exists and how do I use it?

I have been struck for quite sometime now... and any help would be greatly appreciated.

Feel free to mail me at shashi.satya@gmail.com

Thanks in advance.

Title: User Interface

"Although it’s possible, Windows Service typically has no user interface."

Hi, great article, how can I find more information about creating a windows service with windows interface, so far everytime that my windows service timer goes off and executes some code, all the functionality will work as needed but because it won't show the form that I developed (This is actually my biggest problem), it will limit my application's functionality.

Any ideas???

If you guys have something please let me know: ulisesr@mvrmc.org

THANKS!

Title: Windows Service Behaviour

Hello, I have problem with Windows Service that I have created in VB.Net its behaviour is really strange i.e.Sometimes after Istallation and Start it runs but sometimes it just stucks somewhere.Then again this service needs to be re-installed(not just restart) then it runs perfectly very well.
This service does some Asynchronous task using delegates.
I could not understood this behaviour,let me know how can I understand it or what could be reasons.
