>Is it possible to prevent at all previewing of the report during designing? When putting return .F. in the Init and BeforeOpenTable in data environment of the report, this works only in design time. When standalone VFP EXE run, this does not works.

I agree with Hilmar. It would be very hard to design a report if I couldn't preview it.

If it's a problem with data security, or data access, could you let the user use a sample data set?
