Introduction

LearnDelphi.tv is the Internets premier site for instructional video on using Delphi.  Since about 2007 I've been producing free video tutorials on using Delphi.  More recently I've created a series of commercial videos which provide amazing value for money.  While aimed at beginners, even seasoned Delphi users should find the content useful.

Training and Consultancy

Sometimes watching videos and reading articles isn't enough to learn what you need - often it is far more helpful to talk to a real person.  Finding a Delphi expert you can communicate with can be a tricky problem - no longer. Alister Christie is now available on Skype for consultation on Delphi problems and training.

Testimonial

Being entirely new to Delphi I found your videos extremely useful because I’m able to actually watch you working.  I’ve seen many Delphi code examples on the web but very often they are only code, but for me I wanted to know how the graphical elements were pulled together as well… because you do this while you are explaining the components it has given me a handle on what is going on and how it all comes together.  Anyway thank you so much for the video’s.  I’ve bought many teaching aids, books etc… in the past but they get opened looked at and then I find my own way in the end so they don’t get used… I have USED your videos!

Thanks once again,

Greg

Movie #96 - Escaping the Try...Finally...Free Nest

We all want to do the right thing with memory management and make sure we tidy up after ourselves. However as our code gets buried in successive layers of object allocation, try, finally, free "nests" it all becomes a bit onerous -- and, well, resembling a pterodactyl nest. In this session, we look at a technique to flatten out your code so that it will look less attractive as habitation for a friendly pterosaur, and as a side benefit, improve readability. Along the way we use interfaces, generics and anonymous methods to build our over-engineered object de-allocation artifice.  Watch the video on YouTube. This video is about half an hour long.
