Module Name:

legal.c
|

|
Abstract:
|
|||
|
|
|
|||
|
|
This module performs actions related to the establishment of
|
|||
|
|
a legal notice to be displayed at logon time.
|
|||
|
|
|
|||
|
|
Legal notice display is controlled by the value of:
|
|||
|
|
|
|||
|
|
Key: \Hkey_local_machine\Software\Microsoft\
|
|||
|
|
Windows NT\CurrentVersion\Winlogon
|
|||
|
|
Value: [REG_SZ] LegalNoticeText
|
|||
|
|
Value: [REG_SZ] LegalNoticeCaption
|
|||
|
|
|
|||
|
|
If either of these contain strings, then a legal notice
|
|||
|
|
dialog is displayed at logon.

Routine Description:

|
|
This function is used to get the current legal notice caption and
|
|||

|
|
|||
|
|
Arguments
|
|||

|
|
|||
|
|
hwnd - The caller's window. This is used if we need to put
|
|||
|

|
|||
|
|
|
|||
|
|
Caption - Points to a unicode string which is to be modified
|
|||
|
|
to contain the legal notice caption. If there is a caption,
|
|||
|
|
then the Buffer field of this structure will point to an
|
|||
|
|
allocated string. The length fields will be appropriately
|
|||
|
|
set.
|
|||
|
|
|
|||
|
|
Body - Points to a unicode string which is to be modified
|
|||
|
|
to contain the legal notice text. If there is a text,
|
|||
|
|
then the Buffer field of this structure will point to an
|
|||
|
|
allocated string. The length fields will be appropriately
|
|||
|
|
set.

|

Return Values:
|
|||
|
|
|
|||
|
|
TRUE - The value has been successfully retrieved.
|
|||
|
|
|
|||
|
|
FALSE - we ran into trouble querying the current setting.
|
|||
|
|
|
|||
|
|
If an error is encountered, then an error popup will be
|
|||
|
|
displayed by this routine.
