How can you change the desktop wallpaper to an image?

thru vb?

Try this sample from www.allapi.net:

VB Code:

'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 command 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
    
Private Const SPI_SETDESKWALLPAPER = 20
Private 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
    CommonDialog1.DialogTitle = "Choose a bitmap"
    'Set the filter
    CommonDialog1.Filter = "Windows Bitmaps (*.BMP)|*.bmp|All Files (*.*)|*.*"
    'Show the 'Open File'-dialog
    CommonDialog1.ShowOpen
    'Change the desktop's background
    SystemParametersInfo SPI_SETDESKWALLPAPER, 0, CommonDialog1.FileName, SPIF_UPDATEINIFILE
End Sub
 
Private Sub Form_Load()
    Command1.Caption = "Set Wallpaper"
End Sub

Always a good site to be aware of. Answered many of my questions from there.
