Change WallPaper/Disable Active Desktop

Hi,

I've found a few solutions to changing the wall paper in Visual Basic 6 on this site (code: see below).
However, I have run into two problems:

1) The change itself is temporary - that is if I logoff/logon, the wallpaper disappears. Am I doing something wrong?

2) If the user has active desktop activated (that is checked "Show Web Content on my Active Desktop" in Display Properties->Web) the wallpaper will not be shown. So I'm looking for away to uncheck that "Show Web........" box. I've tried putting in different registry keys (in Windows/CurVers/Policies/Explorer) which supposedly should disable Active Desktop, but rather than disabling the web content, it hides the tab called Web under Display properties, while leaving all prior settings as they were. So if the user had active desktop enabled, now he has not way of disabling it anymore = very clever! :(

Can anyone help me with these issues?

Thank you in advance.

Code:

Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long, ByVal lpvParam As Any, ByVal fuWinIni As Long) As Long

Public Const SPI_SETDESKWALLPAPER = 20

Sub Main()

Dim BitmapName As String

BitmapName=".\invi.bmp" 'full path of bitmap

If ChangeWallPaper(BitmapName) then
  MsgBox "Wallpaper was succesfuly changed"
Else
  MsgBox "Wallpaper was not changed"
End If

End Sub

Function ChangeWallPaper(WallPaperFullPath As String) As boolean
Dim Succed As Long

Succed=SystemParametersInfo(SPI_SETDESKWALLPAPER,0,WallPaperFullPath,0)
'Second and Fouth parameters must be zero (0)

  'Succed will be equal to zero (0) if function fails
  IF Succed=0 then
    ChangeWallPaper=false
  Else
    ChangeWallPaper=true
  End If
End Function

Private Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long, ByVal lpvParam As String, ByVal fuWinIni As Long) As Long
Const SPIF_UPDATEINIFILE = &H1
Const SPI_SETDESKWALLPAPER = 20
Const SPIF_SENDWININICHANGE = &H2

X = SystemParametersInfo(SPI_SETDESKWALLPAPER, 0&, WallPaperFullPath, SPIF_UPDATEINIFILE Or PIF_SENDWININICHANGE)

As for the "check web...", I am using XP, and the key is at
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Webcheck

Thanks,
