Delphi is a statically typed language, but there are some tricks you can use if you want to be able to do some dynamically typed coding. In this Delphi programming tutorial we create a custom variant type (descending from TInvokeableVariantType). We then override Get and SetProperty to handle arbitary properties (that don't exist at design time). This video is about nine minutes long and you can watch it here.
In this Delphi programming tutorial we start with an application that loads and saves some settings out of an ini-file. We then tidy up the code a bit by creating a new class inheriting from TIniFile that uses properties with getter and setter methods to change the settings rather than ReadString / WriteString. This makes the code much nicer as you get code completion and error insight. We also make use of the Initialization and Finalization sections of a unit to create and free our new class. This video is 10 minutes long and you can watch it here.
In this Delphi Programming tutorial we take a look at how we can use the CloneCursor method to share data between multiple ClientDataSets. This example is based on the classic fish facts application and is a bit over six and a half minutes long. You can watch it here.
In this video we take a look at techniques for migrating applications from the BDE to the DB-Express 4 Framework (DBX4), in particular BlackFishSQL (now obsolete). This video is a bit under 45 minutes long and you can watch it here. This video is a replay of my presentation at CodeRage III on December 2, 2008. The current recommendation is to use FireDAC as the database engine of choice for BDE migrations.
I challenged myself to come up with 100 useful IDE tips and hints, and then explain them all in 45 minutes. Did I succeed? Watch and see. Okay - that was the abstract to my CodeRage III talk. Some of the hints are a bit lame, but others I hope you will find really useful. This video is about 50 minutes long and you can watch it here.
In this Delphi Programming video we write a tiny Quote of the Day application using the Quote of the Day service. This video is three and a half minutes long and was recorded at 1024x768 (normally I do 800x600 so they work on YouTube, oops - I can't be bothered doing it again). I was originally going to popup the quote in a balloon hint, however Camtasia 3 did not record the balloon for some reason - I guess I'll leave that as an excersie for the interested. You can watch the video here.
