Wallpaper ermitteln/setzen

[CalganX]

Hi,
wie ist es möglich, dass aktuelle Hintergrundbild zu ermitteln, bzw. zu ersetzen?
Müsste irgendein Key in der Registry sein. Aber ich finde mal wieder nix..

Ich habe hier von Swissdelphicenter etwas für dich:

Delphi-Quellcode:

procedure TForm1.Button1Click(Sender: TObject); 
var 
  sWallPaperBMPPath: string; 
begin 
  sWallPaperBMPPath := 'C:\[WinDIR]\wall.bmp'; 
  if not SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, Pointer(sWallPaperBMPPath), 
    SPIF_SENDWININICHANGE) then 
    ShowMessage('Succesful.') 
  else 
    ShowMessage('Failed!'); 
end; 


// 3. Set the wallpaper for the Active Desktop. 
{ 
  You may have noticed that using SystemParametersInfo to change the wallpaper 
  when ActiveDesktop is turned on doesn't work. The reason is because you need 
  to use the IActiveDesktop COM interface. Using SystemParametersInfo still works, 
  but it doesn't update the wallpaper. 
  Requires Internet Explorer 4.0 or later). 
} 



uses 
  ShlObj, ComObj; 


function ChangeWallpaper(aFile: String): Boolean; 
const 
  CLSID_ActiveDesktop: TGUID = '{75048700-EF1F-11D0-9888-006097DEACF9}'; 
var 
  hObj: IUnknown; 
  ADesktop: IActiveDesktop; 
  str: string; 
  wstr: PWideChar; 
begin 
  hObj     := CreateComObject(CLSID_ActiveDesktop); 
  ADesktop := hObj as IActiveDesktop; 
  wstr := AllocMem(MAX_PATH); 
  try 
    StringToWideChar(aFile, wstr, MAX_PATH); 
    ADesktop.SetWallpaper(wstr, 0); 
    ADesktop.ApplyChanges(AD_APPLY_ALL or AD_APPLY_FORCE); 
  finally 
    FreeMem(wstr); 
  end; 
end;

Danke, habe aber bereits selbst herausgefunden wo:

Code:

HKEY_CURRENT_USER\Control Panel\Desktop
