Im making a simple wallpaper changer. It works when changing the wallpaper but i cant change the pattern of the wallpaper. I tried something like this but it doesnt work :S
SystemParametersInfo(SPI_SETDESKPATTERN, 0, "Center",
SPIF_UPDATEINIFILE | SPIF_SENDWININICHANGE);
Can some1 please show me the proper way of setting the wallpaper pattern?
I assume you mean the centred/ streched / tiled setting that would be the second past value int 1-3
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern Int32 SystemParametersInfo(UInt32 action, UInt32 uParam, String vParam, UInt32 winIni);
private static readonly UInt32 SPI_SETDESKWALLPAPER = 0x14;
private static readonly UInt32 SPIF_UPDATEINIFILE = 0x01;
private static readonly UInt32 SPIF_SENDWININICHANGE = 0x02;
private void SetWallpaper(string path)
{
if (File.Exists(path))
{
Image imgInFile = Image.FromFile(path);
try
{
imgInFile.Save(SaveFile, ImageFormat.Bmp);
SystemParametersInfo(SPI_SETDESKWALLPAPER, 3, SaveFile, SPIF_UPDATEINIFILE | SPIF_SENDWININICHANGE);
}
catch
{
MessageBox.Show("error in setting the wallpaper");
}
finally
{
imgInFile.Dispose();
}
}
}
