* SMH_ServiceEntry()
*
* Purpose:
*
* The ServiceEntry() function is the MAPI entry point to configure

* ensure configuration of the SMH provider.
*
* Parameters:
*
* hinst DLL instance
* lpmalloc OLE style allocator (used by PropSheet())
* lpsup MAPI profile support object
* ulUIParam hwnd that is to be used as UI parent
* ulFlags configuration flags
* ulContext configuration action
* cval count of caller supplied properties
* lpval caller supplied properties to be configured
* lpadmin IProviderAdmin object
* lppmerr [OUT] extended error information
*
* Operation:
*
* The ServiceEntry() uses the IProviderAdmin object to open its
* profile section and retrieve the current set of properties. The
* caller supplied properties are then merged into the set of
* current properties.
*
* If either this set of properties is not sufficient for
* configuration or the caller specifically asked for configuration
* UI, then ServiceEntry() will make calls to bring up its config
* UI.
*
* ServiceEntry() recognizes several configuration flags. If
* SERVICE_UI_ALWAYS and/or SERVICE_UI_ALLOWED are set, UI is
* allowed and we be brought up if appropriate. Is
* MSG_SERVICE_UI_READ_ONLY is set, then the UI should not
* allow the configuration to be modified.
*
* The configuration contexts MSG_SERVICE_DELETE, MSG_SERVICE_INSTALL,
* and MSG_SERVICE_UNINSTALL are ignored and no action is taken.
* MSG_SERVICE_CONFIGURE and MSG_SERVICE_CREATE allow the caller to
* create or update the configuration properties in this providers
* profile section.
*
* SMH will not return extended information in the MAPIERROR in case
* of error
