To expand on Al's example, perhaps you can utilize the additional "IN WINDOW" clause that can be used with PREVIEW? (see on-line help on the REPORT command) Basically you can create a form object (with appropriate settings) to act as a "template" for the actual preview window (i.e. the preview window "inherits" the characteristics of the "template"). As Al had stated, the next problem would be the report toolbar (which generally only appears on the main VFP window).

Basically something along the following:

* NOTE: Using FORM class here directly for sake of illustrating a coding technique, in reality you should
*       use a subclass of FORM (i.e. whatever "master" class you're using for all your forms).   Otherwise
*       there is no other way to set various properties like ShowWindow
oPreviewWin = CREATEOBJECT("FORM")
WITH oPreviewWin
    .NAME = "WPREVIEW"
    .CAPTION = "Report Preview"
    .WIDTH = 800
    .HEIGHT = 600
    .TOP  = (SYSMETRIC(1) - .WIDTH) / 2
    .LEFT = (SYSMETRIC(2) - .HEIGHT) / 2
    .MOVABLE = .T.
    .CLOSABLE = .T.
    .MDIFORM = .T.
    .MINBUTTON = .T.
    .MAXBUTTON = .T.
    .ZOOMBOX = .T.
    .HALFHEIGHTCAPTION = .F.
ENDWITH

* NOTE: The code for saving current directory and restoring it has been added to work around possible problem
*        which could arise if the current directory changes unexpectedly -- which could happen if a "save to file" dialog
*        is used -- even if you don't explicitly code such a thing (e.g. If user selects printer associated with a PDF printer,
*        from which a "save as" dialog would often appear).
lcCurDir = SYS(5)+SYS(2003)   && Save current directory
KEYBOARD "{CTRL+F10}"         && maximize preview window
REPORT FORM (m.cReptForm) ;
    PREVIEW WINDOW wPreview TO PRINT PROMPT
SET DEFAULT TO (m.lcCurDir)   && Restore current directory
RELEASE oPreviewWin
