幻灯片壁纸Windows 7
提问于 2012-07-04 21:05:13
如何以编程方式设置Windows 7壁纸幻灯片？
设置普通壁纸
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern Int32 SystemParametersInfo(UInt32 uiAction, UInt32 uiParam, String pvParam, UInt32 fWinIni);
private static UInt32 SPI_SETDESKWALLPAPER = 20;
private static UInt32 SPIF_UPDATEINIFILE = 0x1;
public void SetImage(string filename)
{
SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, filename, SPIF_UPDATEINIFILE);
}到现在为止我发现了什么：
中的幻灯片有一个ini文件。
C:\Users\CurrentUser\AppData\Roaming\Microsoft\Windows\Themes\
在幻灯片放映期间，壁纸必须位于以下文件夹中：
C:\Users\CurrentUser\AppData\Roaming\Microsoft\Windows\Themes\TranscodedWallpaper.jpg (在幻灯片显示文件自动更改期间)

尝尝这个
public sealed class Wallpaper
{
Wallpaper() { }
const int SPI_SETDESKWALLPAPER = 20;
const int SPIF_UPDATEINIFILE = 0x01;
const int SPIF_SENDWININICHANGE = 0x02;
[DllImport("user32.dll", CharSet = CharSet.Auto)]
static extern int SystemParametersInfo(int uAction, int uParam, string lpvParam, int fuWinIni);
public enum Style : int
{
Tiled,
Centered,
Stretched
}
public static void Set(Uri uri, Style style)
{
System.IO.Stream s = new System.Net.WebClient().OpenRead(uri.ToString());
System.Drawing.Image img = System.Drawing.Image.FromStream(s);
string tempPath = Path.Combine(Path.GetTempPath(), "wallpaper.bmp");
img.Save(tempPath, System.Drawing.Imaging.ImageFormat.Bmp);
RegistryKey key = Registry.CurrentUser.OpenSubKey(@"Control Panel\Desktop", true);
if (style == Style.Stretched)
{
key.SetValue(@"WallpaperStyle", 2.ToString());
key.SetValue(@"TileWallpaper", 0.ToString());
}
if (style == Style.Centered)
{
key.SetValue(@"WallpaperStyle", 1.ToString());
key.SetValue(@"TileWallpaper", 0.ToString());
}
if (style == Style.Tiled)
{
key.SetValue(@"WallpaperStyle", 1.ToString());
key.SetValue(@"TileWallpaper", 1.ToString());
}
SystemParametersInfo(SPI_SETDESKWALLPAPER,
0,
tempPath,
SPIF_UPDATEINIFILE | SPIF_SENDWININICHANGE);
}
