2 Package: XWB - Kernel RPCBroker
3 Date Created: Sept 18, 1997 (Version 1.1)
4 Site Name: Oakland, OI Field Office, Dept of Veteran Affairs
5 Developers: Danila Manapsal, Don Craven, Joel Ivey
6 Description: Signon Form Configuration Dialog.
7 Current Release: Version 1.1 Patch 40 (January 7, 2005))
8*************************************************************** }

10{**************************************************
111.1P31 - Modified to store signon configuration under
12 the HKCU key - this permits users on NT2000
13 machines who have USER access to set their
14 configuration. Also, makes configuration specific
15 to users on machines which might be shared.
16
17 Also make it so that configuration is only written
18 to the registry when the user indicates that it
19 should be saved (previously the default values
20 were written into the registry as well as applied
21 to the window if data was not in the registry).
22 The default values previously stored in the registry
23 would override any changes in the signon window
24 design via coding. To overcome this, if the user
25 does not have saved configuration data, the window
26 generated on opening will be used as the default, and
27 the default data written into the registry as defaults.
28 This will permit the user to restore to the current
29 window defaults if desired, but will not overwrite
30 changes released for the window in later patches.
