Registry Entries
DCOM introduced the concept of Application IDs (AppIDs), which group configuration options for one or more DCOM objects into a centralized location in the registry. You specify an AppID by indicating its value in the AppID named value under the object's CLSID.
By default, an ATL-generated service uses its CLSID as the GUID for its AppID. Under HKEY_CLASSES_ROOT\AppID
, you can specify DCOM-specific entries. Initially, two entries exist:
LocalService
, with a value equal to the name of the service. If this value exists, it is used instead of theLocalServer32
key under the CLSID.ServiceParameters
, with a value equal to-Service
. This value specifies parameters that will be passed to the service when it is started. Note that these parameters are passed to the service'sServiceMain
function, notWinMain
.
Any DCOM service also needs to create another key under HKEY_CLASSES_ROOT\AppID
. This key is equal to the name of the EXE and acts as a cross-reference, as it contains an AppID value pointing back to the AppID entries.
