CenterWindow property

Available for window objects (Window, MDIWindow and DialogBox).

Read/Write only at design time

Specifies how a window object will be positioned on the screen when shown for the first time. It can be one of the following values:

0 Manual	Window is positioned according to its Left and Top properties
1 Parent	Window is centered related to its parent
2 Screen	Window is centered on the screen
3 Default	Window is positioned according to Windows defaults (default)

REMARKS: If value Parent is specified and the window has no parent, it will be centered on the screen. On the other hand, if value Screen is specified for a window which is an MDI child (MDIChild property set to TRUE), the value for the property will be changed to Default.
