MapiSvc.inf Service Provider Sections
mapisvc.inf includes one service provider section for each of the entries listed in the Providers entry in the preceding message services section. Service provider sections are similar to message service sections in that both types of sections contain entries in this format:
property tag = property value
However, service provider sections and message service sections differ in that such property entries are the only type of entry included in service provider sections. There can be no additional or linked sections for service providers; all service provider information must be contained within the one section.
Some of the properties set in message service sections are also set in service provider sections because these properties make sense for both. The PR_DISPLAY_NAME property is an example. Both service providers and message services have a name that is used for display in the configuration user interface. Depending on the service provider, that name may or may not be the same. Other properties are specific to service providers.
Typical service provider sections include the following entries, all of which are required:
PR_DISPLAY_NAME = string
PR_PROVIDER_DISPLAY = string
PR_PROVIDER_DLL_NAME = name of DLL file
PR_RESOURCE_TYPE = long
PR_RESOURCE_FLAGS = bitmask
The PR_PROVIDER_DLL_NAME (PidTagProviderDllName) entry is similar to PR_SERVICE_DLL_NAME; it indicates the filename for the DLL that contains the service provider. Message service code may be stored with one of its service providers in the same DLL file or exist as a separate DLL. Note that no suffix is included in the entry regardless of the target platform; MAPI takes care of adding a suffix if necessary.
PR_RESOURCE_TYPE (PidTagResourceType) entry represents the type of service provider; service providers set it to the appropriate predefined constant. Valid values include MAPI_STORE_PROVIDER, MAPI_TRANSPORT_PROVIDER, and MAPI_AB_PROVIDER.
Another property entry that applies to both message services and service providers, the PR_RESOURCE_FLAGS (PidTagResourceFlags) entry indicates options. The settings for this property entry can differ depending on the service provider. For example, some message store providers might set PR_RESOURCE_FLAGS to STATUS_NO_DEFAULT_STORE if they can never operate as the default message store.
Three examples of service provider sections follow. The [AB Provider] section is the service provider section for the Default Address Book service. The [MsgService Prov1] and [MsgService Prov2] sections belong to My Own Service; the first is an address-book provider section and the second is a message-store provider section.
