Do you mean you need a custom preview window?
I use:
Local whatCaption, m.showpicrep, m.name
m.showpicrep = .T.
m.name = CustomerName
whatCaption = "Race Report Program - Click Close Window Icon to Return"
oRepForm = Createobject("Form")
With oRepForm
.Caption = whatCaption
.WindowState = 2
.Show()
Endwith
Repo Form "reports\" + (upickrep) &forclause To Printer Prompt Preview Window (oRepForm.Name)
oRepForm.Release()
