What is the best way to make a Delphi Application completely full screen?

Question

What is the best way to make a delphi application (delphi 2007 for win32 here) go completely full screen, removing the application border and covering windows task bar ?

Answer 1

You need to make sure Form position is poDefaultPosOnly.

Form1.Position := poDefaultPosOnly;
Form1.FormStyle := fsStayOnTop;
Form1.BorderStyle := bsNone;
Form1.Left := 0;
Form1.Top := 0;
Form1.Width := Screen.Width;
Form1.Height := Screen.Height;

Tested and works on Win7 x64.
