Clean Code or Working Code?

21 בדצמבר 2010

I was working on a legacy project with a friend and I sorely bemoaned the messiness of the code. Later, the friend sent me this link and warmly recommended I keep the balance in life. If you cant be bother to read the article, the short of it is that we developers should have more respect for legacy code that works. I acknowledge the underlying truth presented in the article, but I don’t think it gives the whole picture. Just because you can make catastrophic mistakes while disrespectfully accusing code of being a mess, that...

Visual Studio 2010 and Eclipse

12 בדצמבר 2010

From time to time I do some work in C++ for Linux using Eclipse. Many developers say that Eclipse is the state of the art IDE for C++ development on Linux. From my experience, I can say that Eclipse simply pales in comparison with Visual Studio 2010 when it comes to an integrated, streamlined development experience out of the box. Rather than compare the pros and cons of both IDEs I would like to share with you a VS 2010 experience that I enjoy that is often taken for granted by Windows developers and should leave Eclipse...

MVVM : Injecting INotifyPropertyChanged Into an Existing Class

10 בדצמבר 2010

Download the source code for this post here. Using MVVM in Silverlight and WPF I often encounter the following problem. I have a business class that needs to be exposed through the ViewModel. For this, it needs to implement INotifyPropertyChanged or expose Dependency properties. I take the side of those who prefer to keep WPF dependencies out of the ViewModel, so I usually take the path of writing a proxy that delegates properties to the business object and implementing INotifyPropertyChanged. I am not comfortable with this duplication, and I usually pay a price for it when I refactor the business class, but I...

How to Bind to the Index of a Collection in WPF

17 באפריל 2010

Let's say you have a customer class and you are binding a DataGrid to a collection of customers. You would like the index of the customer in the collection to appear in the first column, like so: One way to do this might be to add an Index property to the Customer class and bind to that. I prefer not to go that way because it would pollute our business layer with presentation layer constraints. Solution Here is a different approach using a MultiBinding. You can download the source...

Hierarchical Grid with WPF

A TreeView handles hierarchical data well, and a DataGrid handles tabular data. But what about hierarchical tabular data? A simple example of such a source is a System.IO.DirectoryInfo. Each item can have zero or more children of the same type, enumerated by EnumerateDirectories. I would like to have it displayed like this: Solution You can download the source code for this solution here. The inspiration for this solution came from Delay's Blog by David Anson. I think David's idea of measuring the indentation at each level and compensating for it in...

Top Tips for Rapid Application Development

2 באוקטובר 2009

In recent weeks I have been busy on a number of projects with very tight, almost impossible schedules. When schedules are tight, there is simply not enough time to implement all the steps of a formal development procedure. But I have found that some good practices shine through as time savers every time. Not only do they save time, but they also help produce exensible, maintainable code – which also saves time in the long run. So here are my top tips for Rapid Application Development. Document the requirements succintly. Avoid using document...
