Understanding Arrays in Delphi
The concept of arrays in Delphi is simple: arrays allow us to refer to a series of variables by the same name and to use a number (an index) to tell them apart. Arrays have both upper and lower bounds, and the elements of the array are contiguous within those bounds.

Hide, Slide And Fade Away Controls
In most complex form designs you would have some panels that a user can make visible or hidden. Maybe some controls on some other container controls should be made invisible due to some reasons. A simple Panel1.Visible := false; will make a panel invisible, but why not make it more eye candy by providing a hiding animation. The AnimateWindow API function enables you to produce special effects when showing or hiding windows.

ORMs for Delphi
Working with database data in Delphi can be really simple. Drop a TQuery on a form, set the SQL property, set Active and, voila, here's your database data in a DBGrid. Ok, you do need a TDataSource and a connection to a database, but that's just a few clicks away. Now you want to insert, update and delete data. That's also easy but can get messy. You fight with the corect SQL syntax, but finally have it laid out correctly. Can all this be done easily? The answer is yes: use an ORM!

UDP vs. TCP
Everybody is quite familiar with TCP. Most do know UDP and think it’s an inferior protocol, as it does not ensure that the data bytes sent will arrive at the other site. Thus, UDP imposes less network overhead than TCP and gives the programmer more freedom and more labor by forcing him to deal with the security of the data transport himself.

Introduction to OOP Basics
Use Delphi to learn (or teach) object orientation. Delphi’s roots lie in Pascal, and so it has a sound, structured foundation. It is also strongly object oriented and provides many OO characteristics such as class inheritance, static binding and dynamic binding, and reference semantics. Chapters make extensive use of graded, worked examples to give students hands-on experience in the implementation of OO code.

Virtual Key Code To Character
Windows defines special constants for each key the user can press. The virtual-key codes identify various virtual keys. In Delphi, the OnKeyDown and OnKeyUp events provide the lowest level of keyboard response. To use OnKeyDown or OnKeyUp to test for keys the user presses, you must use Virtual key codes to get the key pressed. Here's how to translate the virtual key code to the corresponding Windows character.

Static vs. Dynamic Loading
Before you can call routines defined in DLL, you must import them. Functions exported from a DLL can be imported in two ways: by declaring an external procedure or function (static), or by direct calls to DLL specific API functions (dynamic). What should be used when: static or dynamic loading of DLLs in Delphi.
