Move taskbar

[Razor]

Ok here we go i want to move the whole taskbar from 1280x30 cordinates(found by winspy 2008) to about 1280x80.But it looks like its not working i can change other stuff like tray,running applications etc.But not whole taskbar.Explain what i am doing wrong.


I currently got this code but it changes size of

Delphi-Quellcode:

var
  MyHandle: THandle;
  WinRect: TRect;
begin
MoveWindow(FindWindowEx(FindWindow('Shell_TrayWnd', nil), 0, '', nil),
             1280, 80, 80, 22, true);

I'm not sure if your code snippet really finds the taskbar...
Take a look at this code (part of amaTaBaSo, OpenSource, use DelphiPraxis Search to locate the whole Sourcecode):

Delphi-Quellcode:

function GetToolbarWindowHandle:HWND;
var
 hDesktop : HWND;
 hTray    : HWND;
 hReBar   : HWND;
 hTask    : HWND;
 hToolbar : HWND;
begin
  hDesktop := GetDesktopWindow;

  hTray    := FindWindowEx( hDesktop, 0, 'Shell_TrayWnd', nil );

  hReBar   := FindWindowEx( hTray, 0, 'ReBarWindow32', nil );

  hTask    := FindWindowEx( hReBar, 0, 'MSTaskSwWClass', nil );

  hToolbar := FindWindowEx( hTask, 0, 'ToolbarWindow32', nil );

  if ( hToolbar = 0 ) then
    MessageDlg(
      'Taskbar konnte nicht gefunden werden',
      mtError,
      [mbOK],
      0);

  Result := hToolbar;
end;

Okay i've found a complete solution by myself using my knowledge however,the code is still not perfect.Can anybody tell me how to erase background of a window via his handle.

Btw i need this for a sidebar if anybody is interested why so much stuff.I want icons on my sidebar.

Delphi-Quellcode:

procedure TForm3.Button1Click(Sender: TObject);
var
myhandle:hwnd;
handle2:hwnd;
handle3:hwnd;
begin



myhandle:=FindWindowEx(FindWindow('shell_traywnd', nil), 0, 'traynotifywnd', nil) ;
if myhandle>0 then begin
windows.SetParent(myhandle,0);
MoveWindow(myhandle,0, -9,TaskBarwidth(myhandle), TaskBarheight(myhandle), true)
       end
   else
showmessage('wont work handle is zero');
end;

Somebody?I am sorry to bump but atleast give me a feedback.If am going the right way..

#2 has all answers you're needing to deal with it.
In your code you're just moving the tray around, leaving all others at their place.

i need to remove the taskbar so its transparent is it possible?

[mr_emre_d]

i dont get it, whats your problem exactly ?

do you want to remove the taskbar or just adjust the size of it ?

for removing(making it invisible) use this:

Delphi-Quellcode:

procedure ShowShellTrayWindow(Show: Boolean);
begin
  ShowWindow( FindWindow( 'shell_traywnd', 0 ), Integer(Show) );
end;

for makin it transparent:

Delphi-Quellcode:

procedure TransparentTrayWindow(Percent: Byte);
var
  hWnd: Cardinal;
begin
  hWnd := FindWindow( 'shell_traywnd', 0 );
  if Percent in [1..100] then
  begin
    SetWindowLong( hWnd, GWL_EXSTYLE,
      GetWindowLong( hWnd, GWL_EXSTYLE ) or WS_EX_LAYERED );
    SetLayeredWindowAttributes( hWnd, 0, Round($FF/$64*Percent), LWA_ALPHA );
  end;
end;

What are we talkig about now? Moving the taskbar or erasing a window's background?

I erased the background so thats done.We are talking about moving.

I got it in X=1280 in Y=0 but cant move it anywhere else.
I can't move it anywhere why is that??

Delphi-Quellcode:

unit Unit3;

interface

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

type
  TForm3 = class(TForm)
    Button1: TButton;
    Edit1: TEdit;
    Label1: TLabel;
    Edit2: TEdit;
    Label2: TLabel;
    Label3: TLabel;
    Label4: TLabel;
    Timer1: TTimer;
    Button2: TButton;
    procedure Button1Click(Sender: TObject);
    procedure Timer1Timer(Sender: TObject);
    procedure Button2Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form3: TForm3;

implementation

{$R *.dfm}


 function TaskBarwidth(handle:hwnd): integer;
var
  hTB: HWND; // taskbar handle
  TBRect: TRect; // taskbar rectangle
begin
  hTB:= handle;
  if hTB = 0 then
    Result := 0
  else begin
    GetWindowRect(hTB, TBRect);
    Result := TBRect.Left- TBRect.Right;
  end;
end;



function TaskBarHeight(handle:hwnd): integer;
var
  hTB: HWND; // taskbar handle
  TBRect: TRect; // taskbar rectangle
begin
  hTB:= handle;
  if hTB = 0 then
    Result := 0
  else begin
    GetWindowRect(hTB, TBRect);
    Result := TBRect.Bottom - TBRect.Top;
  end;
end;




procedure TForm3.Button1Click(Sender: TObject);
var
myhandle:hwnd;
handle2:hwnd;
handle3:hwnd;
begin



myhandle:=FindWindow('shell_traywnd', nil);

if myhandle>0 then

MoveWindow(myhandle,strtoint(edit1.Text), strtoint(edit2.Text),TaskBarwidth(myhandle), TaskBarheight(myhandle), true)

else
showmessage('wont work handle is zero');
end;


procedure TForm3.Button2Click(Sender: TObject);
var
myhandle:hwnd;
begin
myhandle:=FindWindowEx(FindWindow('shell_traywnd', nil), 0, 'traynotifywnd', nil) ;
windows.SetParent(myhandle,0);
end;

procedure TForm3.Timer1Timer(Sender: TObject);
var
miska:tmouse;
begin

  label3.Caption:=inttostr(miska.CursorPos.X);
  label4.Caption:=inttostr(miska.CursorPos.y);
end;

end.

Sorry again,after i setparent(myhandle,0) i can't really move the window anymore why is that?
