I come across the following code with a lot of frequency:
if (myArray.length == Constants.ZERO_INT)
or
if (myString != null && !myString.equals(Constants.EMPTY_STRING))
Neither of these makes much sense to me. Isn't the point of…

I know I'm able to this in PHP, but I can't remember the name or the way to do it, so I'll just explain what it is, and when someone tells me how it's called I'll update this question.
I have some error messages defined as constants on javascript, however, some of those messages need to contain dynamic…

OPTION_1;
}
With constants, you'd just refer to the constant:
String s = TheClass.OPTION_1
But with Enums, you have to specify toString():
String…

I’ve run into the problem a few times now: How to pre-authenticate .NET WebRequest calls doing an HTTP call to the server – essentially send authentication credentials on the very first request instead of waiting for a server challenge first? At first glance this sound like it should be easy:…

Man I can't believe this. I'm still mucking around with OFX servers and it drives me absolutely crazy how some these servers are just so unbelievably misconfigured.

I’ve written quite a bit about Visual FoxPro interoperating with .NET in the past both for ASP.NET interacting with Visual FoxPro COM objects as well as Visual FoxPro calling into .NET code via COM Interop. COM Interop with Visual FoxPro has a number of problems but one of them at least got a lot…

Here’s a nice and simple path utility that I’ve needed in a number of applications: I need to find a relative path based on a base path. So if I’m working in a folder called c:\temp\templates\ and I want to find a relative path for c:\temp\templates\subdir\test.txt I want to receive back subdir\test…
