LearnDelphi.TV – During this session you'll either be thinking "I do that" (and hopefully you'll stop) or "I remember doing that" (while cringing at the memory). There are certain coding patterns that all Delphi programmers seem to use at some stage - some of them sub-optimal, some weird, and some just plain wrong. ...
LearnDelphi.TV – 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 ...
LearnDelphi.TV – In this YouTube video I take a look at the fact that depending on what version of Delphi and if you are using FireMonkey or the VCL, the definitions of Margins and Padding on controls are different. Up until Delphi XE4, the usage of Margins and Padding in FireMonkey was reversed to that of the VCL, ...
LearnDelphi.TV – This is the first in a series of interviews with Embarcadero MVPs, and who better to interview first than the man who is going to be taking the MVP program to the next level - Jim McKeeth. While we attempted to stay on the topic of Delphi programming, we did digress somewhat. Watch the video on ...
LearnDelphi.TV – In this 4 minute video we look at the initialization and finalization sections of Delphi units, and how you can use begin instead of initialization - which may cause you some grief in some instances. Watch the video. In the video I also mention CnPack, which has some highly useful utilities.
LearnDelphi.TV – While I was at the recent Australian Delphi User Group (ADUG) Symposium 2013, I recorded a few interviews with the attendees during the breaks at the Sydney event, watch to find out what people are doing with Delphi in Down Under. Watch it on YouTube, it's 10 minutes long.
LearnDelphi.TV – The Australian Delphi User Group are holding their Annual Symposium and I'm speaking. It is being held in Melbourne (Thursday) and Sydney (Friday) the 21st and 22nd of March 2013. Here is a brief 30 second snippit of my talk - if you want to see the whole thing then you had better register on the ...
LearnDelphi.TV – "If you assign a stringlist to a combobox items property using ':=', you still have to free the stringlist." This tweet by Nick Hodges is probably very obvious to any seasoned Delphi developer, however I think it's far from obvious to someone new to Delphi. In this video we take a look why we need ...
LearnDelphi.TV – In this video we take a look at changing the default font for the code editor in the IDE (Courier New), to something better. After a bit of research online I give a few recommendations as to what font to use, watch this video on YouTube to find out. The video is 5 minutes long.
LearnDelphi.TV – In this video we take a look at some shortcuts to implementing interfaces on classes in Delphi. Knowing these shortcuts will save you a bunch of typing (and hence improve productivity). I produced this video in a response to a post by Nick Hodges (always a fan of his posts), in it he indicates ...
LearnDelphi.TV – The OnCreateItemClass event was introduced to TListView a few versions of Delphi ago, you've probably never noticed it but it's a big improvement on using the Data property on a TListItem - If you have no idea what I'm talking about then you need to watch my video on OnCreateItemClass here. It is ...
LearnDelphi.TV – This video covers how to handle Command Line Parameters in your Delphi applications, with them you can make your applications more flexible giving them some initial state (such as "myprog.exe /SafeMode") or instructing them to perform some actions at start up ("myprog.exe /TakeOverWorld").
