wait function and passing the handle returned by the StopServiceEvent function as the second argument.
The first argument will usually be zero so that no time is wasted if the services has not been requested to
stop.
The authoritative source of information about services is the Microsoft Developers Network (MSDN).
You can access the MSDN on the Microsoft website at msdn.microsoft.com.
3.10.1 What are COM/ActiveX objects?
The Component Object Model
The Microsoft Developer Network (MSDN) is an important source of information for developers about
Microsoft technologies. The MSDN Library (October 1999 edition) defines COM as follows:
The Component Object Model (COM) is a platform-independent, distributed, object-oriented, system
for creating binary software components that can interact. COM is the foundation technology for
Microsoft's OLE (compound documents), ActiveX (internet enabled components), as well as others.
Overview Of Automation
The MSDN Library (October 1999 edition), and defines Automation follows:
Automation (formerly called OLE Automation) is a technology that allows software packages to expose
their unique features to scripting tools and other applications. Automation uses the Component Object
Model (COM), but may be implemented independently from other OLE features, such as in-place
activation. Using Automation, you can:
1. Create applications and programming tools that expose objects.
2. Create and manipulate objects exposed in one application from another application.
3. Create tools that access and manipulate objects. These tools can include embedded macro
languages, external programming tools, object browsers, and compilers.
The objects an application or programming tool exposes are called ActiveX objects. Applications and
programming tools that access those objects are called ActiveX clients. ActiveX objects and clients
interact as follows:
Applications and other software packages that support ActiveX technology define and expose objects
which can be acted on by ActiveX components. ActiveX components are physical files (for example
.exe and .dll files) that contain classes, which are definitions of objects. Type information describes the
exposed objects, and can be used by ActiveX components at either compile time or at run time.
Irie Pascal and ActiveX objects
Irie Pascal accesses the type information about exposed ActiveX objects at run time only. At compile
time Irie Pascal does not know anything about the names or types of the objects' methods or properties.
