Registering the Service Provider (Windows CE 5.0)

Send Feedback

For ActiveSync to recognize a service provider, the provider must have registry entries on both the Windows-based desktop computer and on the Windows CE–based device. The object types must also be registered.

**Note   **The CEUTIL DLL functions are especially helpful when adding desktop registry entries for Windows CE. See Using the CEUTIL Helper DLL for ActiveSync.

To register a service provider on the Windows-based desktop computer

1. Provide a unique programmatic identifier (ProgID) for the desktop provider.

2. Generate a GUID (ClassID) for the service provider.

3. Create the following keys in the Windows registry.

   HKEY_CLASSES_ROOT\CLSID\ClassID\InProcServer32

   HKEY_CLASSES_ROOT\CLSID\ClassID\ProgID

   HKEY_CLASSES_ROOT\ProgID\CLSID

The default value of the InProcServer32 key is the path of the DLL that implements the IReplStore interface. For Microsoft Outlook it would be the path to Outstore.dll. The default value of the ProgID key is MS.WinCE.Outlook. The default value of the CLSID key is the GUID for the store.

Register the object types for the service provider in a subdirectory under HKEY_LOCAL_MACHINE. The following screen capture illustrates the desktop registry location for the appointment, contact, and task object types.

Each object type name is a key. The following five values must be defined under each key.

• Default

  A description of the object type. For example, Outlook Appointment Object.

• Display Name

  The name of the object that you want to display. For example, Appointment.

• Plural Name

  The plural name of the object. For example, Appointments.

• Store

  The OLE programmatic identifier, ProgID, of the store that implements the IReplStore and IReplObjHandler interfaces. For example, MS.WinCE.Outlook.

• Disabled

  A value indicating whether the service provider is displayed as disabled or enabled in ActiveSync. A nonzero value indicates the service provider is disabled.

The following screen capture illustrates the values defined under the Appointment object type.

When a user connects a new Windows CE-based device to the desktop and a new device profile is added to Mobile Device folder, the registry keys for the synchronization objects under HKEY_LOCAL_MACHINE are automatically copied to HKEY_CURRENT_USER.

To register a service provider on the Windows CE–based device

• Register the device provider under HKEY_LOCAL_MACHINE\Windows CE Services\Synchronization\Objects.

On the Windows CE-based device, each object-type name is a key, but only two values are defined, Store and Display Name. Store refers to the module that exports the functions for this object type. Display Name refers to the name of the object type.

The following registry data shows the device registration for the Appointment object type.

Store         "pegobj.dll"
Display Name  "Appointment"
