I have a .NET Windows.Forms diagram editor that can export its diagrams as bitmaps. It also comes with a command line utility that just converts diagrams to bitmap images. I don't want to scale the diagram to a given bitmap size; instead, I want to size the bitmap based on the diagram's bounding box. I can easily determine it after dra...
I've created some classes that will be used to provide data to stored procedures in my database. The varchar parameters in the stored procs have length specifications (e.g. varchar(6) and I'd like to validate the length of all string properties before passing them on to the stored procedures. Is there a simple, declarative way to do th...

Hello everybody, I read this interesting line here, in an answer by Jon Skeet. The interesting line is this, where he advocated using a delegate: Log.Info("I did something: {0}", () => action.GenerateDescription()); Question is, what is this ()=> operator, I wonder? I tried Googling it but since it's made of symbols Google couldn't b...
I have a constructor that take two interfaces, they are the same interface, but need to be different implementations: public class Foo { public Foo(IBar publicData, IBar privateData) { } } What I'd like to happen is that structuremap would pass in a concrete implementation of IBar as class PublicData and class PrivateData ...
Hello everybody, what if I had a native C++ function in which, depending on the result of the function, the responsibility of deleting a certain pointer (delete[]) differs between the caller and the function. I would of course check for the return value and act accordingly in C++. Question is, what if the function was marshalled between...

I'm always referencing DLL's in my C# code but they have remained somewhat of a mystery which I would like to clarify. This is a sort of brain dump of questions regarding DLL's I understand a DLL is a dynamically linked library which I understand means that at run time another program can access this library to get "functionality". Howe...
I was reading the book "Apress Pro LINQ: Language Integrated Query in C#" and I came across partial methods, but I really don't understand what is the need for them. I think the examples in the book (properties before and after change) can be implemented using events. So any explanation? ...
I have a legacy app that uses SoapFormatter to persist a graph of objects (maybe 50 different classes). I want to move away from using this as it is deprecated, and increasingly hard to continue to support deserializing from old files as the classes change. I want to use DataContractSerializer going forward. Does anyone have any suggest...

I've come across a weird discrepancy between BigIntegers used by .Net 4.0 and Silverlight 4.0; In .Net, BigInteger has a Parse and TryParse method where as in the Silverlight version, it does not have either of these. If you look at the .Net version of System.Numerics in Reflector, you also see that when you disassemble the code, every ...

Can/Should my POCO's encompass multiple Databases if applicable? The reason I ask is that I am in the process of refactoring a legacy Enterprise App that was built in stages. Unfortunately, each stage had it's own separate DB (at least they are all on the same SQL instance). Because of this I can easily see where a typical Business ...

Since Twitter won't use basic authentication (login, password) anymore, I'm converting my app to using twitter with oauth authentication. In my code this was ok, but I also use Elmah to tweet the errors on a specific twitter account. But it seems Elmah only works with basic authentication. Is it true? Any workaround? Thanks ...
