stry := bmp文件名
Systemparametersinfo(SPI_SETDESKWALLPAPER, 2,pchar(stry), SPIF_UPDATEINIFILE);
结果在98下面桌面没有变化，桌面点右建桌面已经是这个文件了点确定才更换
winxp下就可以一执行就换了桌布。

如果用下面语句就没事了，速度很慢
var xx : array[50] of char;
SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, SPI_SETDESKWALLPAPER, integer(@xx));
我想知道上面这句和下面这句话各自的作用
Systemparametersinfo(SPI_SETDESKWALLPAPER, 2,pchar(stry), SPIF_UPDATEINIFILE);

Systemparametersinfo(SPI_SETDESKWALLPAPER, 2,pchar(stry), SPIF_UPDATEINIFILE);
发送消息告诉windows更换桌布
SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, SPI_SETDESKWALLPAPER, integer(@xx));
是告诉windows刷新重绘说面上的所有窗体吧
把分给我jxy ghm 哈哈！
