Learn how to use Delphi interfaces and TInterfacedObject to prevent memory leaks and access violations when loading and unloading runtime packages.
Learn how Delphi's RTTI and custom attributes enable a loosely coupled plugin architecture, with a practical example, size impact, and verification steps.
Learn how LiveBindings lets you declaratively sync TEdit, TLabel and other controls with data model properties, cutting manual event‑handler code.
Learn how to bind a TEdit to a TDataSet field with LiveBindings, reducing boilerplate code while understanding the trade‑offs.
Learn how to keep a VCL/FMX form responsive by offloading blocking work to TTask and marshaling UI updates safely with TThread.Queue.
Learn how Delphi generics provide type‑safe collections and algorithms with zero runtime overhead, see a reusable cache example, and verify specialization via the map file.
I need to verify that my Delphi VCL application can successfully obtain an access token from the Microsoft identity platform using the OAuth 2.0 authorization code flow with PKCE, while avoiding any use of production Azure AD credentials or real user data. The test environment must use a dedicated Azure AD test tenant, a localhost redirect URI that matches t
The Parallel Programming Library (PPL) in RAD Studio provides the ITask interface for background execution. While ITask.Cancel allows for the signaling of a task to stop, the worker thread must manually poll for this state to exit gracefully. A challenge arises when implementing strict timeouts for asynchronous operations. Because ITask does not include a na
Integration boundary A Delphi application is planned to use FireDAC for least-privilege database access and RAD Server/EMS for token-based API access. The design goal is consistent credential use and handling of expired credentials across the two component boundaries. FireDAC supports least-privilege access via connection parameters and delegates authenticat
