Thread.Synchronize
A general mistake many Delphi developers are making is accessing GUI classes from other threads directly (in a multi-threaded application). It’s a mistake I was doing for a long time. Eventually I started using SendMessage to synchronize with…
Read More »FastMove: Optimizing System.Move
This post describes a technique that can be used to optimize some RTL functions at run-time. At the end of the post there’s a unit; add it to your uses list (preferably as the first one) and the…

It seems the more you look, the more you find. There are a few interesting points in how strings are handled in Delphi; I’ve talked before about the particularities of String type in Delphi, so I’ll not touch…

The title is probably a bit misleading. I’m not going to talk about the “future of Delphi” rather about the concept of “future evaluation” in Delphi. You might have heard about the Delphi Prism product that Embarcadero/CodeGear is…
