* This function initiates the registry for the UPS service and the
* configuration application. When called, this function examines
* the registry to determine if it needs to be initalized. If the key
* HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UPS\Config\ServiceProviderDLL
* is present, the registry is assumed to be initialized and no initialization
* is done. If the key is not present the following Keys are updated:
* Status
* Config
* ServiceProviders
*
* The values for the ServiceProviders key is supplied in the regdefs.h
* header file.
*
* Parameters:
* none
*
* Returns:
* TRUE if able to open registry keys with write access.

The following example helps to explain more the members of the DialogAssociations struct.
Say we have an instance of this struct as follows:
DialogAssociations da = { eREG_POWER_SOURCE,
IDC_POWER_SOURCE_LHS,
IDC_POWER_SOURCE,
IDS_STRING,
IDS_UTILITYPOWER_UNKNOWN,
RESOURCE_INCREMENT,
2,
eDeepGet,
0,
0 };
This describes a registry field called eREG_POWER_SOURCE. If we look at
tUPSDataItemID above we see that eREG_POWER_SOURCE has a value of 4. If
we then look at g_upsRegFields in datacces.c we that the RegField at index
4 has the following data:
{ HKEY_LOCAL_MACHINE, STATUS_KEY_NAME, TEXT("UtilityPowerStatus"), REG_DWORD },
The DoUpdateInfo function, for example, takes this information when updating
the onscreen data in the main UPS page. The function gets the RegField
information, as above. It then looks to see if it needs to do a deep get (read
directly from the registry), or a shallow get (take data from the current
values stored in the regfuncs buffers. If the registry item theValueType is
one of the string type then the string value is copied into the resource
string identified by theResourceInsertID. In this case theValueType is
REG_DWORD. In this case the DWORD is read from the registry directly. Its
value (say it had a value of 1) is then added to IDS_UTILITYPOWER_UNKNOWN
giving a value which corresponds to IDS_UTILITYPOWER_ON. The string
IDS_UTILITYPOWER_ON is then loaded and used as a parameter value when
loaded the parameterized string resource identified by the
theResourceInsertID string id. This string (which should include the inserted
text) is then displayed in the control identified by theDisplayControlID.
