>Hello to every VFP programmers this is a challenger for me, I need to develope a Report designer made in VFP5 or VFP6 to be added into an application, someone of yours have an idea ?

Why not buy any one of the commercial reportwriters that can be incorporated into a VFP app - far less time consuming, far less bug-prone, and minimal programming time on your part. Something like FoxFire! or Stonefield Reports is going to provide more tested functionality for the price than you could provide on a roll-your-own basis.

I'm a big fan of Stonefield's products (I've used Stonefield Database Toolkit for a long time as a database maintenance tool in my apps) - their web site is http://www.stonefield.com, and they have demo versions that you can download for VFP5 and 6 on the web site. The cost is $299/developer for the product, and this includes Stonefield Query, an end-user Query builder product.

FoxFire! from Micromega is another well-known, well supported report writer tool that can be incorporated into your apps; the Developer Version, which allows you to distribute the runtimes was $395 the last time I looked. You can get it through www.hallogram.com

These are not the only app-integratable and distributable report writers by any means; both companies have a long-term reputation for producing a quality product.
