The sign of a true manager is delegation (C# style)
Today I thought I would write a bit about delegates in C#. Up till recently I have managed to side step any real understanding of what delegates do and why they are useful – I mean, I know roughly what they do and have used them a lot, but I have never really got down dirty with them and mucked about. Recently however with my renewed interest in Silverlight delegates came up again as a possible solution to a particular problem, and suddenly I found myself opening a bland little console application ......

The Gates Books–Finished
Today I can finally say that I finished both of my Bill Gates books that had been lying on the shelf for several years. The books were… The Road Ahead (1995) Business @ the Speed of Thought (1999) I enjoyed “The Road Ahead”, purely because it was fun to read about someone looking into the future at technology, while I could read it looking at the past. In fact I was quite impressed with how much he got right and it was also nice to remember “The good old days”. Business @ the Speed of Thought was ......

Coding is Easy - Software Engineering Isn’t
Yes, coding in its general sense is extremely easy, and it is getting easier by the day. So easy that a small child can rattle off some code and end up with something that works. In fact, for many years there I was in my little bubble with the IDE as my own personal universe where I could define my own rules on how things worked with little regard to anything anyone else said or did. If I wanted on Monday to declare all variables in small case, then that was fine. If on Tuesday I decided that it ......

.Net Micro
A while back I purchased a RFID scanner that could be connected to a PC and programmed via VS. It was a fun purchase an though the import duties nailed me, I was glad to get the little gadget. Last night while listening to .Net Rocks I heard of another company that sells similar components for .Net Micro. Check out their websites…. TinyClr GHI Electronics .Net Micro Website Trossen Robotics ......

Cancelling WPF Application.Shutdown
Today I spent the better part of an hour trying to figure out what I had had done wrong. I had an application that when the user click’s “exit”, it should prompt if they want to save the last unsaved file, or cancel the exit. If the select cancel it should not exit the application. Everything seemed fine in my code, all I was doing was calling Application.Current.Shutdow... And then capturing the Closing event and setting cancel to true.. (see SO question here) Long story short, If should not have ......

We have been using LogicNP’s CryptoLicensing for some of our software and I was battling to understand how exactly the whole process worked. I was sent the following document which really helped explain it – so if you ever use the same tool it is well worth a read. Licensing Basics LogicNP CryptoLicensing For .Net is the most advanced and state-of-the art licensing and copy protection system you can use for your software. LogicNP CryptoLicensing System uses the latest cryptographic technology to ......

Where have I been for the last month?
So, I have been pretty quiet for the last month or so. True, it has been holiday time and I went to Cape Town for a stunning week of sunshine and blue skies, but the second I got back home I spent the remainder of my holiday on my pc viewing tutorials on www.tekpub.com Craig Shoemaker, who I got in contact with because of his podcast, sent me a 1 month free subscription to the site and it has been really appreciated. I have done a lot of WPF programming in the past, but not any asp.net stuff and ......
