Embed a FastReport designer in Delphi, bind a dataset, generate runtime reports, export to PDF, and clean up resources to avoid leaks. Follow the step‑by‑step guide for a stable reporting solution.
Batch inserts, updates, and deletes with RAD Studio FireDAC Array DML to cut database round-trips.
Concatenating user input into SQL strings is a liability. See how to use TFDQuery parameters in Delphi to separate code from data, reduce injection risk, and avoid type-mapping surprises.
Delphi’s streaming system persists only the properties it can discover through RTTI. Learn how published declarations, stored directives, and ownership rules control what reaches the .dfm file—and how to verify the round-trip.
Learn how to diagnose and fix EAccessViolation errors in RAD Studio VCL applications by identifying nil and dangling pointers using the integrated debugger and FastMM4.
LiveBindings lets Delphi devs tie UI controls to data sources declaratively, cutting boilerplate but adding RTTI overhead. This post walks through a simple VCL example, shows how to set up bindings, highlights trade‑offs, and offers a quick sanity check.
Fetch only the rows your Delphi grid needs by binding PageSize and Offset to FireDAC TFDQuery, with limits and verification steps.
FireDAC lets RadStudio apps keep data access code stable across desktop and mobile by separating connection, command and presentation, with driver swaps instead of rewrites.
