Registry restrictions?

[Scott Turchin]

Does anyone know of any registry restrictions whereas registry entries cannot be written in?
I had read there may be a few long ago, but I doubt it...
I am administrator, although it's a Win98 box this code fails:
It's just writing an entry to pop up a message box prior to logon either on 98 or NT/2k, pretty handy too:

             Case %IDMAIN_SET
                If osinfo.dwPlatformId = %VER_PLATFORM_WIN32_NT Then
                    SaveSetting %HKEY_LOCAL_MACHINE,ByVal "SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon", ByVal "LegalNoticeCaption",g_MsgTitle
                    SaveSetting %HKEY_LOCAL_MACHINE,ByVal "SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon", ByVal "LegalNoticeText",g_MsgText
                Else
                    SaveSetting %HKEY_LOCAL_MACHINE,ByVal "SOFTWARE\Microsoft\Windows\CurrentVersion\Winlogon", ByVal "LegalNoticeCaption",g_MsgTitle
                    SaveSetting %HKEY_LOCAL_MACHINE,ByVal "SOFTWARE\Microsoft\Windows\CurrentVersion\Winlogon", ByVal "LegalNoticeText",g_MsgText
                End If


This SaveSetting function has worked for years, and still does work everywhere else...
Function SaveSetting(lpKey As Long,ByVal cMainkey As String, ByVal Key As String, _
                     ByVal Setting As String) As Long
Local hKey   As Long
Local Result As Long
Local zText  As Asciiz * 2048

' ** Create the section
If RegCreateKeyEx(lpKey, cMainKey + Chr$(0),0, "", %REG_OPTION_NON_VOLATILE, _
                   %KEY_ALL_ACCESS, ByVal %NULL, hKey, Result) <> %ERROR_SUCCESS Then
    Exit Function
End If

' ** Save the value for the key
If Len(Setting) Then
    zText = Setting
    RegSetValueEx hKey, Key+Chr$(0), 0, %REG_SZ, zText, Len(Setting)+1
Else
    RegSetValueEx hKey, Key+Chr$(0), 0, %REG_SZ, ByVal %NULL, 0
End If
    ' ** Close the key
    RegCloseKey hKey
    Function = %TRUE
End Function

Question2, what's the size limit on string registry entries?
I've seen paragraphs in this particular entry but I think my $CRLF is doing something bad....
With no $CRLF this saves:

Computer Tresspass 1 as defined by RCW 9A.52.110 - A person is
guilty of Computer Tresspass in the first degree, if the person without
authorization intentionally gains access to a computer system or electronic
database of another; AND a. The access is made with the intent to commit
another crime, OR b. The violatoin involves a computer or database maintained
by a government agency. Computer Tresspass in the first degree is a class C
felony. (up to 3 years in prison)

Computer Tresspass 2 as defined by RCW 9A.52.120 - A person is
guilty of Computer Tresspass in the second degree, if the person without
authorization intentionally gains access to a computer system or electronic
database of another; AND a. The access is made with the intent to commit
another crime, OR b. The violatoin involves a computer or database maintained
by a government agency. c. Intentionally gains access to a computer or database
of another under circumstances not constituting the offense in the first degree.
Computer Tresspass in the 2nd degree is a Gross Misdemeanor. (up to 1 year
in prison.)
