title: Delphi: "Resource not found" in design mode - why?
body: <p>I got an error, and I don't know why I got it...</p>
  
  <p>So: I have a new component, based on sAlphaButton.
  This have ImageList property, and my component extend this button with my own captions/images, translated to hungarian.</p>
  
  <p>I used LoadRes to get the predefined images.</p>
  
  <p>See this:</p>
  
  <pre><code>procedure TScrollPNGButton.LoadAsImageListFromRes(ResNames : TStrings; IL : TsAlphaImageList);
  var
      s : string;
      i : integer;
  begin
      IL.CLear;
      for i := 0 to ResNames.Count - 1 do begin
          s := ResNames[i];
          AddImageFromRes(hInstance, IL, s, ifPNG);
      end;
  end;
  
  
  procedure TScrollPNGButton.LoadResToImageList;
  var
      sl : TStringList;
  begin
      sl := TStringList.Create;
      try
          sl.Text :=
              Trim(
                      'scrollpngbutton_ok'#13 +
                      'scrollpngbutton_cancel'#13 +
                      'scrollpngbutton_close'#13 +
                      'scrollpngbutton_yes'#13 +
                      'scrollpngbutton_no'#13 +
                      'scrollpngbutton_refresh'#13 +
                      'scrollpngbutton_print'#13 +
                      'scrollpngbutton_email'#13 +
                      'scrollpngbutton_add'#13 +
                      'scrollpngbutton_delete'#13 +
                      'scrollpngbutton_edit'#13 +
                      ''
                  );
          LoadAsImageListFromRes(sl, FImgs);
      finally
          sl.Free;
      end;
  end;
  
  
  constructor TScrollPNGButton.Create(aOwner : TComponent);
  begin
      inherited Create(aOwner);
      FImgs := TsAlphaImageList.Create(nil);
      inherited Images := FImgs;
      LoadResToImageList;
  end;
  </code></pre>
  
  <p>It is working good when I use it from code.
  But when I registered it, and I try to put into a form, I got error:</p>
  
  <blockquote>
    <p>Error
    Resource scrollpngbutton_ok not found.
    OK   </p>
  </blockquote>
  
  <p>I don't understand it, because I put the {$R *.res}, and from code this is working.
  Why the Resource not found? Is creation failed, or what?</p>
  
  <p>Ok, I can use Loaded; to set the images in design time, but Loaded is not called in runtime.</p>
