CSysService

Microsoft. Windows NT. supports a service application type which conforms to the interface rules of the Service Control Manager (SCM). Services can be installed, configured and controlled by applications using the service functions included in the Microsoft. Win32. application programming interface (API).

CSysService is a C++ class which wraps methods around several of the Win32. API service functions, providing an object-oriented interface to these functions, grouping common variables and structures in a single class object. The result is an extensible base class capable of installing, enumerating, modifying, controlling and removing a service application in the Service Control Manager.

The CSysService class can be extended (sub-classed) to enhance its capabilities. Refer to the Microsoft Platform SDK: DLLs, Processes, and Threads documentation from the MSDN (support.microsoft.com).

CSysService contains the following methods, fully documented in the download file.

Sample Application

NTServiceSetup is a Microsoft. Windows NT. program to manage service applications in the Service Control Manager database.

Features:

• Create, modify, control and remove service applications.


• VisualC++ project and source code.
• Based on CSysService class.
• Allows creation of parameter registry entries for use with Microsoft's SrvAny.

Double-clicking (or selecting and pressing Enter) on a row in the list will display the service properties in an edit dialog window. Selecting the add button will display an empty edit dialog window to allow a new service to be added.

NTServiceSetup was originally part of a larger Windows NT. console-based control application project. The modularity employed in the design of the control application allowed extraction of NTServiceSetup to a stand alone executable program.

NTServiceSetup can only access the host upon which it is running. However, since it is based upon the CSysService class, this functionality can be easily added.
