hmm not heard of suipack before, but I presume you dont have your taskbar set to autohide or anything.
Is this problem happening when you run it through the IDE, just the executable, or both?
Does it happen when you have "WindowState = wsMaximized" at design time?

 

by: mis82Posted on 2004-05-24 at 03:27:31ID: 11141689

no my taskbar is static , the problem in one form only any other applications fine too
also the problem in the exe file and the IDE,
i tried the maximize state i encounterd a new problem that the form goes to right buttom  and freeze
i reset the run process

 

by: mikelittlewoodPosted on 2004-05-24 at 03:41:02ID: 11141736

Im unsure what this issue might be then Im afraid.
If its not too big a job you could cut components from the form and create it again just to see if that form was bugged or not.

Sorry I wasnt too much help

 

by: mikelittlewoodPosted on 2004-05-24 at 03:42:15ID: 11141741

Is this form you are opening the main form, or do create it at runtime from a button etc
Maybe you are showing it incorrectly, or even hiding it without realising

 

by: mis82Posted on 2004-05-24 at 03:45:16ID: 11141754

its a main form  not runtime ,
did u understand the problem?   when i set it to maximize the whole form goes to right and buttom and i cant see the end of the form
but the left top almost set to  center of the screen

 

by: mikelittlewoodPosted on 2004-05-24 at 03:51:51ID: 11141781

O I C !

Well it sounds like the "Left" and "Top" values of the form are going a bit screwy.
Do you want the form maximised as soon as it starts up?
You could see if this would help. Try putting it in you Form1.Create procedure
Form1.Left := 0;
Form1.Top := 0;

You said you have played around with the "Position" property as well yes?
poScreenCentre etc

not working sorry...

 

by: mikelittlewoodPosted on 2004-05-24 at 04:12:10ID: 11141886

Im not sure then Im afraid  :o/

 

by: esoftbgPosted on 2004-05-24 at 04:39:08ID: 11142012

DO you use some of these events:
procedure TForm1.FormActivate(Sender: TObject);
begin
//........
end;

procedure TForm1.FormPaint(Sender: TObject);
begin
//........
end;

procedure TForm1.FormResize(Sender: TObject);
begin
//........
end;

procedure TForm1.FormShow(Sender: TObject);
begin
//........
end;

Check them for any statements like:
Height := ....;
Width := ....;
Left := ....;
Top := ....;

handle the maximizing like this :

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
  private
    procedure OnMaximize(var Msg : TMessage); message WM_SYSCOMMAND;
    procedure OnNCClick (var Msg : TMessage); message WM_NCLBUTTONDBLCLK;
  public
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

{ TForm1 }

procedure TForm1.OnMaximize(var Msg: TMessage);
begin
  if Msg.WParam = SC_MAXIMIZE then
    begin
      ShowMessage('Maximizing');
      inherited;
    end
  else
    inherited;
end;

procedure TForm1.OnNCClick(var Msg: TMessage);
begin
  ShowMessage('Maximizing');
  inherited;
end;

end.
