To remove the icon from the Taskbar, you need to call a Windows API call:
BOOL ShowWindow(HWND hwnd,int nCmdShow);
Delphi makes it very easy to use this command. All you need to do is supply the Application.handle and SW_HIDE to remove the icon from the Taskbar.
To display the icon on the Taskbar use SW_SHOW in your ShowWindow parameter.
Both examples are shown in the source below.
procedure TForm1.Button1Click(Sender: TObject);
begin
ShowWindow (Application.Handle, SW_HIDE);
end;
procedure TForm1.Button2Click(Sender: TObject);
begin
ShowWindow (Application.Handle, SW_SHOW);
end;
begin
ShowWindow (Application.Handle, SW_HIDE);
end;
procedure TForm1.Button2Click(Sender: TObject);
begin
ShowWindow (Application.Handle, SW_SHOW);
end;
