Article #28186: How can one prevent a TForm from being moved or resized?

QUESTION:

How can one disable a TForm from being moved or resized?

ANSWER:

Place the following code in the FormCreate event:

procedure TForm1.FormCreate(Sender: TObject);
var
hMenuHandle : HMENU;
begin
hMenuHandle := GetSystemMenu(Form1.Handle, FALSE); //Get the handle of the Form
if (hMenuHandle <> 0) then
DeleteMenu(hMenuHandle, SC_MOVE, MF_BYCOMMAND); //disable moving
DeleteMenu(hMenuHandle, SC_SIZE, MF_BYCOMMAND); //disable resizing
end;

If you also want to prevent the user from minimizing and maximazing the form, in the Object Inspector, select the form you are concerned with and under the BorderIcons, set the biMinimize and biMaximize properties to False.
