-Delphi production to achieve geometry form, such as a ring can be realized window, oval window, a rectangular window (general form), corners rounded form (that is, rounded window), right click in the window that opens, it will see a pop-up control menu, select the menu option corresponding form, the window switches to the corresponding style, can be directly compiled with Delphi7 source code.
