The value is stored in the registry...

HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\DefaultIcon

Empty:
%SystemRoot%\System32\shell32.dll,31

Full:

%SystemRoot%\System32\shell32.dll,32

Change them there and issue a desktop refresh like this:

const WM_REFRESH_DESKTOP = $A065;

  SendMessage(0, WM_COMMAND, WM_REFRESH_DESKTOP, 0);

What OS are you using?

If it is Win2K, we have to try another approach. I have
seen another way of refreshing the desktop but I can not
recall where. I will see if I can find it.

Can you show the code you are using to modify the icon and
refresh? You say that the icon changes back to the original
after you delete a file?

So you can not show the code, huh? Hmm, makes it hard to
imagine what may be causing your problem.

If you can't help me, I can't help you...

Ok, found it...

SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_FLUSHNOWAIT, nil, nil);

will invalidate the desktop. it takes a very short time
but it does do it automatically!

it's not working (now i'm running 95)
i've seen a refresh but the recycle bin icon is not changing (after a change the key of course)

i was thinking about this API but with other approche.
(i whant to delete a file send a message, restore the file and send the message again,but is not a good idea)

Hey, I tried it in Win98 and it works. My guess is that YOU are doing something WRONG.

If you can not show how you are doing it, then you are on
your own and anyone else here will tell you the same thing.

i didn't say that ii don't want to show you my code
here it is:

     Reg.WriteString('Shell Icon Size','16');
     SendMessage(HWND_BROADCAST,WM_SETTINGCHANGE,SPI_SETICONMETRICS,LPARAM(2));
     Reg.WriteString('Shell Icon Size',IntToStr(count));
     SendMessage(HWND_BROADCAST,WM_SETTINGCHANGE,SPI_SETICONMETRICS,LPARAM(2));


it's not cool that's why i esitate to show it to you!
it's working in Win'95 and Win'98

You said you wanted to change the recycle bin icon. The code you show does not do that.

Try this code:

const WM_REFRESH_DESKTOP = $A065;

procedure TForm1.Button1Click(Sender: TObject);
var
  Reg: TRegistry;
begin
  Reg := TRegistry.Create;
  try
    // You can try this key, also
    // HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}
    Reg.RootKey := HKEY_CLASSES_ROOT;
    if Reg.OpenKey('\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\DefaultIcon', False) then
    begin
      Reg.WriteString('','"%SystemRoot%\System32\shell32.dll,32"');
      Reg.WriteString('Empty','"%SystemRoot%\System32\shell32.dll,32"');
      Reg.WriteString('Full','"%SystemRoot%\System32\shell32.dll,33"');
    end;
  finally
    Reg.CloseKey;
    Reg.Free;
    SendMessage(0, WM_COMMAND, WM_REFRESH_DESKTOP, 0);
    SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_FLUSHNOWAIT, nil, nil);
  end;
end;

You can not change the SIZE of the recycle bin icon
without changing them for every other desktop icon.

That value cames from a book about undocumented Windows API
calls. You can view the value by using Winsight to monitor
windows messages.

There is an article on changing the Startmenu bitmap
on www.delphi3000.com.

Hi ,

I tested your codeEddie and I try to replace the default icon with mine .

I have replaced


                          Reg.WriteString('','"%SystemRoot%\System32\shell32.dll,32"');
                          Reg.WriteString('Empty','"%SystemRoot%\System32\shell32.dll,32"');
                          Reg.WriteString('Full','"%SystemRoot%\System32\shell32.dll,33"');

with

                          Reg.WriteString('','c:\1.ico"');
                          Reg.WriteString('Empty','"1.ico"');
                          Reg.WriteString('Full','"2.ico"');

The recycleBin icon is replaced but the animation for full-empty don't work . All the time I have just the icon for empty ( in my case 1.ico )
Can you tell me where I wrong ?

I see that you did not give the FULL PATH to the icons
in your WriteString calls.

Give that a try...

Refresh what menu?

I don't have code to modify the start menu bitmap but I do
know there is some out there.

Do you yet have code to change StartMenu bitmap?

I will have to wait to check my source to modify the
recycle bin icons till I get home tonight. The code I
provided does not work on Win2K, hmmm...

This is the code I found for changing the Start Menu Bitmap:

procedure TForm1.Button1Click(Sender: TObject);
begin
  NewImage := TPicture.Create;
  NewImage.Bitmap := Image1.Picture.Bitmap;
  case Button1.Tag of
  0:
    begin
      StartButton := FindWindowEx(FindWindow('Shell_TrayWnd', nil), 0,'Button', nil);
      OldBitmap := SendMessage(StartButton, BM_SetImage, 0, NewImage.Bitmap.Handle);
      Button1.Tag := 1;
    end;
  1:
    begin
      SendMessage(StartButton,BM_SetImage,0,OldBitmap);
      Button1.Tag := 0;
    end;
  end;
  NewImage.Free;
end;

Can you post yours?
