[RESOLVED] Changing Windows CE 5.0 desktop wallpaper

[PaxPsychosis]

Hi,

I'm looking for a way to change the desktop wallpaper on Windows CE from Visual Basic 2005. After a lot of digging, the only solution I've found is shown below, but it doesn't work:

    Public Declare Function SystemParametersInfo Lib "Coredll.dll" (ByVal uAction As Integer, ByVal uParam As Integer, ByVal lpvParam As String, ByVal fuWinIni As Integer) As Integer

    Public Const SPI_SETDESKWALLPAPER As System.UInt32 = &H14
    Public Const SPIF_UPDATEINIFILE As System.UInt32 = &H1
    Public Const SPIF_SENDWININICHANGE As System.UInt32 = &H2



    Sub Main()

        SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, "\Windows\wallpaper.bmp", SPIF_UPDATEINIFILE Or SPIF_SENDWININICHANGE)

    End Sub

SystemParametersInfo returns 0. I've tried setting the wallpaper to "(None)" and that has the same result. The "wallpaper.bmp" file exists, and I'm able to set the wallpaper to that manually on the device. I'm aware that SystemParametersInfo seems to only work with bmp files, but that won't be an issue if I can just get it working.. or is there an alternative method?

Thanks
