Sorry, but I see now that this answer by Viktornet does not work. I have just bought a new computer and I tried my app on it and it does not show the full screen. Can we re-open this question?

Thanks
   Shawn

P.S: The computer I developed my app on has screen resolution of 800 X 600. My new one I just tried it on is 1024 X 768. I would like my app to be robust enough to adapt to all different screen sizes/resolutions and be always 'full-screen'.

Hello!

Just put the following code in onShow event of your form:

{Set form size to full screen}
Form1.Left:=0;
Form1.Top:=0;
Form1.Height:= Screen.Height;
Form1.Width:= Screen.Width;

{make your window top-most,so it would be ontop of the taskbar and all other windows}
SetWindowPos(Form1.Handle, HWND_TOPMOST, 0,0,0,0,SWP_NOACTIVATE+SWP_NOMOVE+SWP_NOSIZE);

Hope this helps! ;-)

Go to: http://www.delphi3000.com/article.asp?ID=1266 for
'Make your app to fill entire screen excluding taskbar' article .

To show over taskbar just change the SetBounds values with:

SetBounds(0,0, Screen.Width, Screen.Height);

Freshman3k - your suggestion does indeed make my form cover the whole screen, but the rightmost and bottommost part of my form is now blank and it looks crappy.

I guess what I mean to say is how to make my form - AND all its components - cover the full screen. I developed my app in a 800 X 600 resolution environment and my form covers the whole screen there (excluding taskbar) and it looks good; but when you run it on a 1024 X 768 environment, the right and bottom parts of my form are empty... all the components are still bunched over to the top and left. Do you see what I mean?

>ok, so any idea how I can do it?
yes,Try any of these components:

http://www.torry.net/vcl/sizers/sizers/easysize.zip
http://www.torry.net/vcl/sizers/sizers/eresizer.zip
http://www.torry.net/vcl/sizers/sizers/dcwinsizer.zip

they resize all the components on the form ,so the components resize with the form together

Hi Freshman3k, your form resizing suggestion, together with the 'easysize' resizing component works well, but my form now covers the taskbar. How do I get it to not do this? Does it have something to do with this statement:

SetWindowPos(Form1.Handle, HWND_TOPMOST, 0,0,0,0,SWP_NOACTIVATE+SWP_NOMOVE+SWP_NOSIZE);

Thanks

Just a side note, the SWP_NOACTIVATE, SWP_NOMOVE, SWP_NOSIZE are intended to be used with an OR inbetween not a plus sign..

Like so...
SetWindowPos(Form1.Handle, HWND_TOPMOST, 0,0,0,0,SWP_NOACTIVATE OR SWP_NOMOVE OR SWP_NOSIZE);

And you should not use the entire screen if you do not want to obscure the taskbar.

Procedure SetSize;
Var
 R : TRect;
 I : LongBool;
begin
  I := SystemParametersInfo(SPI_GETWORKAREA, 0, @R, 0);
  If I Then Begin
    Top := R.Top;
    Height := R.Bottom - R.Top;
    Left := R.Left;
    Width := R.Right - R.Left;
  End;
End;

Ohh...i may have misunderstood your objective...

if you want your form to be below the taskbar change

HWND_TOPMOST to HWND_NOTOPMOST

aztec ,

I think that you ignore me so I will leave this topic .

If you give couple minutes to my comments you can see that is the answer for your problem.

Read the title : 'Make your app to fill entire screen excluding taskbar'

This function calculate the all work area ( for any resolution ). The result is a FULL SCREEN FORM THAT DON'T COVER THE TASKBAR FOR ANY SCREEN RESOLUTION.

Wish you luck,
Nick

P.S. Tested already on my system .

This is the code used by me :

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs;

type
  TForm1 = class(TForm)
    procedure FormCreate(Sender: TObject);
  private
    procedure WMSettingChange( var Msg: TMessage); message WM_SETTINGCHANGE;
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

function Area: TRect;
begin
 SystemParametersInfo(SPI_GETWORKAREA, 0, @Result, 0);
end;

procedure TForm1.WMSettingChange( var Msg: TMessage);
var R: TRect;
begin
 if (Msg.WParam=SPI_SETWORKAREA) then begin
   R:=Area;
   SetBounds(R.Left, R.Top, R.Right-R.Left, R.Bottom-R.Top);
   end;
 Msg.Result:=0;
end;

procedure TForm1.FormCreate(Sender: TObject);
var R: TRect;
begin
 R:=Area;
 SetBounds(R.Left, R.Top, R.Right-R.Left, R.Bottom-R.Top);
end;

end.

So far I have received several suggestions, but no one has offered a complete solution that fully works.
