CComModule

CComModule is a class provided by the Active Template Library (ATL) in Microsoft's Visual C++. It is designed to simplify the creation of COM (Component Object Model) servers. COM is a Microsoft technology for enabling interaction between software components or applications. CComModule is a template class that encapsulates the functionality needed to register and unregister a COM server, manage class factories, and handle other COM-related tasks.

The primary purpose of CComModule is to reduce the boilerplate code that developers would otherwise need to write to create a COM server. It provides methods for registering and unregistering the server, as well as for managing the lifetime of class factories. This includes handling the creation and destruction of objects, as well as managing the reference counts for these objects.

CComModule is typically used in conjunction with other ATL classes, such as CComObject and CComClassFactory. These classes work together to provide a comprehensive framework for creating COM servers. The CComModule class is initialized with a set of class factories, which are responsible for creating instances of the COM objects. These class factories are registered with the COM system, allowing other applications to create instances of the COM objects.

In summary, CComModule is a powerful tool for developers creating COM servers. It simplifies the process by providing a framework for registering and unregistering the server, managing class factories, and handling other COM-related tasks. This allows developers to focus on the specific functionality of their COM objects, rather than the underlying COM infrastructure.
