Setting Desktop Image (without access?)

[ae_jester]

Hi,

At my college, they have turned off the control panel so that nobody can change anything, including the desktop image.

But, people somehow find a way to set the desktop picture somehow, because every so often a new desktop image appears on some computers. If I were to write a VB program that could set the desktop image, would windows let it happen?

If not, how the heck are these people setting the desktop? Does anyone have any ideas?

The api call is SystemParametersInfo

ya.. just found it.. here is the API guides example

'This project needs
'- a common dialog box
'  (To add the Common Dialog Box to your tools menu, go to Project->Components (or press CTRL-T)
'   and select Microsoft Common Dialog control)
'- a button
Private 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
Const SPI_SETDESKWALLPAPER = 20
Const SPIF_UPDATEINIFILE = &H1
Private Sub Command1_Click()
    'KPD-Team 1998
    'URL: [url]http://www.allapi.net/[/url]
    'E-Mail: [email][email protected][/email]
    'Set the commondialogbox' title
    CDBox.DialogTitle = "Choose a bitmap"
    'Set the filter
    CDBox.Filter = "Windows Bitmaps (*.BMP)|*.bmp|All Files (*.*)|*.*"
    'Show the 'Open File'-dialog
    CDBox.ShowOpen
    'Change the desktop's background
    SystemParametersInfo SPI_SETDESKWALLPAPER, 0, CDBox.filename, SPIF_UPDATEINIFILE
End Sub
Private Sub Form_Load()
    Command1.Caption = "Set Wallpaper"
End Sub

This API would work even on a machine that has the control panel disabled?
