PDF generation is the most common use case for XFRX. It supports font embedding, security passwords, and high-resolution images.
designed for Microsoft Visual FoxPro (VFP). Developed by EQEUS , it transforms native VFP report files ( .frx , .frt ) into electronic formats like PDF, Excel (XLS/XLSX), Word (DOC/DOCX), HTML, RTF, images, and OpenOffice documents . It supports VFP versions 5.0 through 9.0, as well as advanced modern expansions like Advanced VFP (VFPa/VFPa64).
The layout of documents is more exact because the same engine is used for printing and export.
Check if the target file is already open in another program. Invalid report file Ensure the .FRX file is not corrupted and exists. -10 Missing DLL dependency Ensure XFRX.DLL and ZLIB.DLL are in the application root. Share public link xfrx documentation
Variables declared as LOCAL are not visible in XFRX for VFP 8.0, so PRIVATE variables should be used for data preparation.
XFRX can output reports to an intermediate format (an XML-based format that mirrors the report structure). This enables: Post-processing of reports.
: If your code crashes before reaching loSession.Finalize() , the output file may remain locked in memory by the operating system. PDF generation is the most common use case for XFRX
The documentation includes a full example of using XFRX inside a VFP-based web service (e.g., West Wind, ActiveVFP) to stream PDF directly to Response.BinaryWrite .
If the XFRX#LISTENER causes a table open dialog, ensure the PAPERSIZE keyword exists in the report's EXPR field for objtype=1 , objcode=53 .
For applications running on older FoxPro versions that do not support object listeners, XFRX provides a direct transformation pass. Developed by EQEUS , it transforms native VFP report files (
XFRX was never meant to be just another library. It began, in the cramped back room of a university lab, as a whisper between two grad students who wanted to fix how data moved between domains. They called it XFRX because the letters sounded like a promise: a compact courier, fast and adaptable, capable of carrying payloads no matter how messy the endpoints.

Without grasping the factory pattern, you will never correctly manage memory or listener lifecycles.
