The form has a WindowsState property, just like the screen; by setting this property, you control the form attribute to minimize/maximize/make standard the frame for the parent (either a top-level form or the VFP main screen, depedning on how you created the form to behave.) This applies to (B) as well.

>B. And how about MAX. and CLOSE window ??

Close should trigger the form's RELEASE method; you'll need to write code to deal with any data in transition, and to decide if a CLEAR EVENTS is needed to start the application shutdown process.

>C. i have WinFaxPro 9.0 in my PC, while a open the WinFaxPro, a system panel will display on screen. And i can "MOVE" it just press & move on panel. Can i do it in VFP ??

If you mean can you drag a form around on-screen, sure; you may need to add code to keep it from auto-centering, or to move the child forms outside the parent window depending on how the form has been told to behave.
