Pedro -

I did find a "reportbuilder" source .. is that it ?
i tryied to run it , but it seems just a report builder, not the actual report designer... maybe it depends on the parameters passed to reach to the report designer ?

Do not think of ReportBuilder.App as a "builder" in the sense that you may be used to in previous versions of VFP.

Although Craig is correct, the Report Designer itself *is* written in C++ and is not available for developers like us to modify, the ReportBuilder provides almost 100% of the visible UI that the end user interacts with (all the dialogs, if not the actual report layout design surface itself).

The intent here was that in VFP9 you would be able to create a reduced functionality version of the report designer suitable for use by end users. The default report builder implements "protection" for example, which is an easy way to limit the UI for end users.

Alternatively, by respecting the Report builder API as documented in the VFP9 help file, you can replace all the dialogs with your own UI. It's got to be easier than writing your own report designer!
