Application as a toolbar

I can make the OnTop with FormStyle, I can position the app in the upper part of the screen. But I can't figure out how to make windows not use the surface of my application(as if the desktop surface would be smaller, Office Toolbar does this).

Hi,

Try this:

type
  TForm1 = class(TForm)
    procedure FormCreate(Sender: TObject);
    procedure FormDestroy(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;
  rectOri: TRect;

implementation

{$R *.DFM}

procedure TForm1.FormCreate(Sender: TObject);
var
  rect: TRect;
begin
  Left := Screen.DesktopLeft;
  Top := Screen.DesktopTop;
  Width := Screen.DesktopWidth;
  Height := 50; // your form height here

  FormStyle := fsStayOnTop;

  // Get the current available work area
  SystemParametersInfo(SPI_GETWORKAREA, 0, @rectOri, 0);

  // Subtract the rect
  SubtractRect(rect, rectOri, Classes.Rect(Left, Top, Width, Height));

  // Set this to be the new available work area
  SystemParametersInfo(SPI_SETWORKAREA, 0, @rect, 0);
end;

procedure TForm1.FormDestroy(Sender: TObject);
var
  rect: TRect;
begin
  // restore rectOri
  SystemParametersInfo(SPI_SETWORKAREA, 0, @rectOri, 0);
end;

I would suggest creating your app as an appbar... see here for code sample: http://www.delphipages.com/tips/thread.cfm?ID=167
