As I mentioned in a previous post, I’m currently slogging through the melancholic mire of testing .NET/C# code. In the process, I’ve been receiving exceptions which give an HRESULT code in hex (i.e. 8×80020005) and not much else. That got me to wondering what these HRESULTs are and how to decode them. This wondering led me in turn to this page which has an excellent overview of what HRESULTs are and why they matter. I also uncovered a link to a freeware tool called HR Plus which can decode HRESULTs and give you a (usually helpful, sometimes vague) idea of what they mean. Both the page and the tool have been extremely handy to have around. I hope they prove handy for you too.
