In my current project everyone names variables and methods after what they are and what they do. This is good for quickly understanding the code, but with a lot of long varible names comes some headaches, such as when copying a dataset to an entity/object.

Using infragisitcs ultrawebgrid, you add ...
I'm writing a program in Visual Basic 2010. It's a HMI (Human-Machine Interface) and therefore has a whole whack of buttons that just send commands to other devices. As a result, there are a huge pile of event handlers for clicking buttons that can't really be broken down into modules (unless my understanding of modules is wrong). Essen...
Just thought I'd share this in case anyone else has run into this. I did something similar today and it took me a while to figure out why this was causing a problem at runtime. This code: Public Class foo Public bar As String = "blah" End Class Public Sub DoInline() Dim o As New foo Dim f As Func(Of String) With o f = Func...
