How to minimize a window to the taskbar? (i.e. not iconify)

i have a window that i want to minimize (to the taskbar), so i call ShowWindow:

ShowWindow(Handle, SW_MINIMIZE);

Except that rather than minimizing itself (to the taskbar), the window is iconified:

The window is unparented:

Update:

Following some advice from 2002, i try setting the WS_EX_APPWINDOW window style and/or ensuring the window has no owner:

Unfortunately, that changes the behavior of my (Delphi) application because there is now two taskbar icons for my application, rather than one:

This, of course, is an artifact of Delphi (5); and because i was trying to solve another issue.

But that shouldn't affect this question. i'm calling the ShowWindow(..., SW_MINIMIZE) API, and rather than minimize the window Windows is iconifying the application.

That icon on the taskbar is the icon of the Application (Handle) rather than that of the MainForm.

Use:

Application.Minimize;

Edit: But out of both your links, I understand you knew that already...duh ;)

This works for the MainForm:

TForm1 = class(TForm)
private
  procedure WMSysCommand(var Msg: TWMSysCommand); message WM_SYSCOMMAND;
protected
  procedure CreateParams(var Params: TCreateParams); override;

...

procedure TForm1.CreateParams(var Params: TCreateParams);
begin
  inherited CreateParams(Params);
  with Params do
  begin
    ExStyle := ExStyle or WS_EX_APPWINDOW;
    WndParent := GetDesktopWindow;
  end;
end;

procedure TForm1.WMSysCommand(var Msg: TWMSysCommand);
begin
  if Msg.CmdType = SC_MINIMIZE then
    ShowWindow(Handle, SW_MINIMIZE)
  else
    inherited;
end;

And to hide Application.Handle from the taskbar (to only have a taskbar icon for the MainForm): set the Visible property of this Form to True and hide the Application in the project file:

Application.Initialize;
Application.CreateForm(TForm1, Form1);
ShowWindow(Application.Handle, SW_HIDE);
Application.Run;

For this form, ShowWindow(Handle, SW_MINIMIZE); shóuld work. It also provides for the default zooming-feature of Windows when minimizing or restoring.
