/修改
var
Form1: TForm1;
StartButton: hWnd;
OldBitmap: THandle;
NewImage: TPicture;
/ 将代码放入FormCreate事件
procedure TForm1.FormCreate(Sender: TObject);
begin
NewImage := TPicture.create;
NewImage.LoadFromFile(\'C:WindowsCircles.BMP\');
StartButton := FindWindowEx
(FindWindow(
\'Shell_TrayWnd\', nil),
0,\'Button\', nil);
OldBitmap := SendMessage(StartButton,
BM_SetImage, 0,
NewImage.Bitmap.Handle);
end;
/还原
procedure TForm1.FormDestroy(Sender: TObject);
begin
SendMessage(StartButton,BM_SetImage,0,OldBitmap);
NewImage.Free;
end;
for win98se/delphi 5.0通过。
