This is a caching version of SvcEnum. Upon creation, it enumerates all

service factories in the family and keeps them in a list. Then you can
|
||
|
|
call findService() with a search string to quickly find the service you
|

|
|
want. If you don't have a search string, you can still use a SvcEnum.
