RegistrationConnectionType Enumeration


Defines the types of connections to a class object.

Namespace:   System.Runtime.InteropServices
Assembly:  mscorlib (in mscorlib.dll)

public enum RegistrationConnectionType

Member nameDescription

Multiple applications can connect to the class object through calls to CoGetClassObject.


Registers separate CLSCTX_LOCAL_SERVER and CLSCTX_INPROC_SERVER class factories.


Once an application is connected to a class object with CoGetClassObject, the class object is removed from public view so that no other applications can connect to it. This value is commonly used for single document interface (SDI) applications.


The class object is a surrogate process used to run DLL servers.


Suspends registration and activation requests for the specified CLSID until there is a call to CoResumeClassObjects.

The values in the RegistrationConnectionType enumeration are used in the flags parameter of the RegisterTypeForComClients method. These values are the same as those defined in the COM REGCLS enumeration, which is used as the flags parameter in calls to the COM API CoRegisterClassObject.

For more information about CoRegisterClassObject and the REGCLS enumeration, see the MSDN library.
