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…
My quotes.txt file

Author: Rudy Velthuis
I have often been asked about the quotes I use when writing to the newsgroups. These come from a file called quotes.txt, and are placed under my messages by my news client, XanaNews, by some kind of random process. Although, sometimes the quotes are so…

Multiple windows in Delphi
April 26, 2005
Author: deepak S1409
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. Delphi forms do not have the WS_EX_APPWINDOW style set – this style is required if a window needs to appear in the task bar.

One item in my previous post that I specifically didn’t address is the notion of using Eclipse instead of VS. Again, this is something we’d be remiss to ignore. However, the primary ding against Eclipse is its reliance on a…

Author: Tóth Erik
Back after a break. It’s been quite a while since I wrote, so I’ll cut to the chase. Question on newsgroups: How do I set username/password for Basic Authentication on SOAP.

Making "Stay-on-top-forms" do want you want
September 8, 2004
Author: Embarcadero USA
Delphi supports this type of forms by providing the FormStyle property for the TForm class. All you have to
do is to set this property to fsStayOnTop. So why did I write this article? Well, there are a few
things to consider:
Using fsStayOnTop causes flickering of the form, because it recreates the window handle.
If you have a Stay-On-Top-Form (ok, we’ll call…
The Observer Pattern
June 30, 2004
Author: Joanna C1415
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…
Author: Adailton C38044
The reason there are both Table and Query components is due to the fact there are table-oriented databases like Dbase, Paradox, or Access, and there are set-oriented databases like Interbase, Oracle, and MSSQL. These different types of database…
PopupMode and PopupParent
February 10, 2004
Author: Allen
In VCL.NET (and for those of you paying attention, also in the version of Win32-VCL used in the IDE integration pack for Delphi 8) there is a new property on TCustomForm called PopupMode. This controls how the top-level form behaves with respect to Window’s WS_POPUP style. A window that has the WS_POPUP style will always be above it’s “owner” in…
