CeSvcOpen (Windows CE 5.0)
This function opens a service and retrieves a handle to the registry root for a specified logical position.
HRESULTCeSvcOpen( UINTuSvc,LPTSTRpszPath,BOOLfCreate,PHCESVCphSvc);
Parameters
- uSvc
[in] Logical registry subkey as identified by CESVC_* keys. For more information, see Remarks. - pszPath
[in] Pointer to either a subpath to append to the logical subkey, or a device identifier if uSvc is set to CESVC_DEVICEX. - fCreate
[in] TRUE if the subkey should be created, and FALSE if it already exists. - phSvc
[out] Pointer to the handle to the registry subkey for the service. This handle is equivalent to a HKEY value and can be used by other CEUTIL API functions, as well as Win32 registry manipulation functions.
Return Values
Returns S_OK if the operation completed successfully. Otherwise, this function returns a Microsoft Win32 error code.
Remarks
The first time a device is connected to the desktop and a partnership is created, the synchronization and filter settings are copied from the MACHINE_ROOT to the partnership subkey under LOCAL_ROOT. The following table maps registry locations to predefined constants. MACHINE_ROOT is used for HKEY_LOCAL_MACHINE\Software\Microsoft\Windows CE and LOCAL_ROOT is used for HKEY_CURRENT_USER\Software\Microsoft\Windows CE Service.
| CEUTIL constants | Registry key | Description |
|---|---|---|
| CESVC_CUSTOM_MENUS | MACHINE_ROOT\CustomMenus | Custom menus registry root. |
| CESVC_DEVICE_SELECTED | LOCAL_ROOT\Partners\<Selected Device ID> | Root subkey for the currently selected device. |
| CESVC_DEVICES | LOCAL_ROOT\Partners | Individual device subkeys are created under this key. |
| CESVC_DEVICEX | LOCAL_ROOT\Partners\<Device ID> | Particular device root subkey. |
| CESVC_FILTERS | MACHINE_ROOT\Filters | The Filters registry root. New filters should register themselves here. |
| CESVC_ROOT_MACHINE | MACHINE_ROOT | Microsoft ActiveSync root hierarchy under HKEY_LOCAL_MACHINE. |
| CESVC_ROOT_USER | LOCAL_ROOT | ActiveSync root hierarchy under HKEY_CURRENT_USER. |
| CESVC_SERVICES_COMMON | MACHINE_ROOT\Services | Services registry root. |
| CESVC_SERVICES_USER | LOCAL_ROOT\Partners\<Device ID>\Services | Root Services subkey for a particular device. |
| CESVC_SYNC | LOCAL_ROOT\Partners\<Device ID>\Services\Synchronization | Synchronization registry root for a particular device. |
| CESVC_SYNC_COMMON | MACHINE_ROOT\Services\Synchronization | Synchronization registry root. New synchronization services should register here. |
When the handle returned by CeSvcOpen is no longer needed, the application should call the CeSvcClose function.
CeSvcOpen is part of CEUTIL, a utility DLL for dealing with desktop registry entries for Windows CE. CEUTIL functions are for use by desktop applications that need to communicate remotely with Windows CE–based devices. These functions are not available to applications running on Windows CE–based devices.
