While doing some bug fixing and cleanup in a web application, I had the chance to go a little deeper into the jQuery user input validation framework. There are many tutorials available about implementing custom validations. But what I wanted to do was to extend the default validations with my own code, while preserving the existing functionality, and to do it site-wide.
So…

Ever since before Delphi 1, the (then Delphi only) RAD Studio IDE has been full of home-grown multicast event class types. I usually refer to these as an “event bus.” This is from my hardware days when I designed microcontroller based…

Recently, I was exploring writing an ADO SQL logging tool (sorta like BDE monitor) – more details on that later – which would show SQL statements on the screen as they ran. All was well until I figured I needed to be able to see my SQL logging form even when a Modal window was being displayed. TForm.ShowModal() disables all other windows in the current thread, so…

From a recent thread in borland.public.delphi.nativeapi.win32:
There’s a problem in the way Delphi handles multiple open forms. Delphi applications can have multiple forms, and you will notice that each form does not appear on the task bar.

Introduction
When we use Delphi to design forms and data modules, every time we place a component on the designer, several things change: the form now shows an appropriate representation of the component, the object inspector changes to show the properties of the component and, if we press Alt-F12, we see the .DFM file now contains information about the component. Whether…
