You could use EnumWindows to enumerate all top level windows. Then you have to check each window. Only windows with owner=0 and parent=0 are shown as buttons in the taskbar.
Is that what you want?

if yau are looking to get the taskbar use

var
  hw: HWND;
begin
  hw:= FindWindow('Shell_Traywnd', nil);

here is an example of getting the taskbar then show it or hide it...

procedure TForm1.Button1Click(Sender: TObject);
var
  hw: HWND;
begin
  hw:= FindWindow('Shell_Traywnd', nil);
  if hw <> 0 then
    if IsWindowVisible(hw) then
      ShowWindow(hw, SW_HIDE)
    else
      ShowWindow(hw, SW_SHOW);
end;

Later

seb24,

tell us a little bit more about what you want to do. Why did you reject Boris' answer? You should always write a comment when rejecting an answer, so we all know what didn't work or what it was that you didn't like.

Here is an example......

function GetTaskWindows(Handle : HWND; lparam : LPARAM) : Bool;stdcall;
var
  Name : array[0..MAX_PATH] of char;
begin
  if GetWindow(Handle, GW_CHILD) = 0 then begin
    GetWindowText(Handle, Name, SizeOf(Name));
    if StrPas(Name) <> '' then
      Form1.ListBox1.Items.Add(Name);
    Result := True;
  end;
end;

procedure TForm1.FormClick(Sender: TObject);
begin
  EnumWindows(@GetTaskWindows, 0);
end;

This is a better code actually....

function GetTaskWindows(Handle : HWND; lparam : LPARAM) : Bool;stdcall;
var
  Name : array[0..MAX_PATH] of char;
begin
  if GetParent(Handle) = 0 then begin
    GetWindowText(Handle, Name, SizeOf(Name));
      if StrPas(Name) <> '' then
        Form1.ListBox1.Items.Add(Name);
    Result := True;
  end;
end;
procedure TForm1.FormClick(Sender: TObject);
begin
  EnumWindows(@GetTaskWindows, 0);
end;

Viktor, sorry, not complete...  :-)

seb24, sorry, too. Have forgotten two things:

var taskWindows : string;

Function EnumWindowsCallBack(HWND : hwnd; LPARAM : lParam) : bool stdcall;
var s1   : string;
Begin
  result:=true;
  If (GetWindow(HWND,GW_OWNER)=0) and (GetParent(HWND)=0) and IsWindowVisible(HWND) and
     (GetWindowLong(HWND,GWL_EXSTYLE) and WS_EX_TOOLWINDOW=0) then begin
    SetLength(s1,MAX_PATH);
    GetWindowText(HWND,pchar(s1),MAX_PATH);
    s1:=string(pchar(s1));
    If s1<>'' Then taskWindows:=taskWindows+s1+#$D#$A;
  end;
End;

begin
  EnumWindows(@EnumWindowsCallBack, 0);
  MessageBox(0,pchar(taskWindows),'TaskWindows',0);
end;
