XFRX is a comprehensive reporting tool for Visual FoxPro (VFP) that enables high-fidelity output to PDF, Excel, HTML, and other formats through traditional session objects or VFP 9.0 listeners. Key features detailed in the documentation include robust PDF encryption and PDF/A support, customizable built-in previewers, and simplified deployment via inclusion in VFP project files.
