It's not very pretty, and I'm not sure it's even close to what you're after, but you could try this.

lo_Form = CREATEOBJECT("Form")
lo_Form.SHOW()
DEFINE WINDOW PreviewWindow FROM 1,1 TO 15,40 IN WINDOW (lo_Form.NAME) ;
   NOCLOSE NOFLOAT NOGROW NOMINIMIZE NOZOOM TITLE ""
SHOW WINDOW PreviewWindow
REPORT FORM MyReport.frx PREVIEW IN WINDOW PreviewWindow NOCONSOLE NOWAIT

>I would like to preview a report inside a form control and disable the print control. Can that be done.
