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
|
||
up an error popup.
|
||
|
||
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
