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.
Enable FireDAC connection pooling in Delphi VCL/FMX apps to reuse database handles, reduce open latency, and stabilize server connections under concurrent load.
Use Delphi LiveBindings to declaratively format dataset values in UI controls, reducing manual event-handler code.
An architecture note on Delphi LiveBindings: where declarative binding beats event-handler boilerplate, the smallest maintainable design, and the failure modes that should push you back to explicit code.
LiveBindings lets RAD Studio developers declaratively bind UI controls to data objects, reducing boilerplate and keeping UI and model in sync. This guide walks through a concrete VCL example, shows two‑way binding with converters, and lists common pitfalls and performance tips.
Guide to picking TTask or Parallel.For in Delphi VCL apps, with constraints, trade‑offs table, and ready‑to‑run code examples.
Diagnose and resolve UI freezes in Delphi VCL caused by TThread.Synchronize deadlocks. Learn to identify lock contention and replace blocking calls with TThread.Queue.
Freeze-prone VCL form? Use TTask.Run from System.Threading to move blocking work off the UI thread, TThread.Queue to update controls safely, and learn the capture and exception pitfalls.
