Sebastian,
There is a free Word document viewer application that you can use instead. You can get it from the MS website. It would launch as it's own application window, it'll not be part of your app forms.
>I'm looking for an OCX or some other stuff to have a document preview for word documents within a VFP form (as assistance for an open dialog for word documents within VFP).
>BTW: I tried the OleBoundControl, but this is very slow – any other ideas?
