Q: I'm looking for a way to hide the Caption (or Title) bar of my application. I want to have a Sizable Window with no Caption Bar. Is this possible?
A: You might try this method connected to onCreate event:
procedure TForm1.FormCreate(Sender: TObject);
begin
SetWindowLong(Handle,GWL_STYLE, GetWindowLong(Handle,GWL_STYLE)
AND NOT WS_CAPTION);
ClientHeight := Height;
end;
