CComModule

class CComModule : public _ATL_MODULE

CComModule implements a COM server module, allowing a client to access the module's components. CComModule supports both DLL (in-process) and EXE (local) modules.

A CComModule instance uses an object map to maintain a set of class object definitions. This object map is implemented as an array of _ATL_OBJMAP_ENTRY structures, and contains information for:

• Entering and removing object descriptions in the system registry.
  
  
• Instantiating objects through a class factory.
  
  
• Establishing communication between a client and the root object in the component.
  
  
• Performing lifetime management of class objects.

When you run the ATL COM AppWizard, the wizard automatically generates _Module, a global instance of CComModule or a class derived from it. For more information about the ATL COM AppWizard, see the article Creating an ATL Project.

In addition to CComModule, ATL provides CComAutoThreadModule, which implements an apartment-model module for EXEs and Windows NT services. Derive your module from CComAutoThreadModule when you want to create objects in multiple apartments.
