Example: Lets say that I want to create a TreeView of geography and I want the top nodes(s) to be countries. I could do this by: World Mexico Japan But what the user wants is: Mexico Japan It would be ...
Has anybody heard of a "type dictionary" that uses types as keys and supports inheritance? In my application I'd like to have a dictionary from types to functions, sort of like this: Dictionary<Type, Func<object, object>> Transformers; The idea is that it would be used to transform an object in some fashion based on its type: // Tra...

This post is in continuation of this one. I am trying to understand if I am the only one who misses and needs the ability of a .NET generic type to inherit one of its generic parameter types. The challenge is to collect compelling reasons in favour of this feature or, alternatively, get to know that there are none. I will start with m...
I am experiencing some annoying behavior with Visual Studio .NET 2008. We have created a base form, and a base grid derived from Infragistics UltraGrid. In the base form, we have set some properties like colors, font size, etc. 1. We create a new Windows Form, (i.e. DerivedForm) 2. We change the inheritance to BaseForm, by simply addin...
I've never tried this - so I don't know if I'd run into memory issues. But can a SqlDataReader read a trillion records? It's all streamed correct? I'm a little green to what the SQL/TDS protocol is doing under the covers. UPDATE Translate Trillion to mean very large number. I probably should have said something like 1 billion or 100 mi...

I am using the simplest example of remoting that I could find, sharing an object between a windows service and a windows forms program (client), running on the same machine. The service instantiates the object like this: serviceConfigRemote = new serviceConfigDataRemote(); serverChannel = new TcpServerChannel(9090); ChannelServices.Reg...

Question I was wondering if anyone knows where I might find C# versions of the VB.NET code snippets built in to Visual Studio (2008)? What are Code Snippets? VB.NET has a wide-ranging collection of snippets that cover most of the basic tasks one might want to accomplish, i.e. File I/O, LINQ, DB connectivity, and so on. C# has a much s...
Background I have a GridView where input in Column1 depends on the input Column2. If a user enters a N in Column2 the system will put a Y in Column1. The Validatons are implemented using Regexs and Custom validation. I would prefer a validation solution that doesn't use JavaScript. |Column1| Column2| __________________ | Y |...
is there a way to see if a date is valid without using validators? I can't use validators in this instance and it's a long story that is too much to type but it has to do with nested controls not being able to be found in javascript. But before i insert a date i want to make sure it is valid right before the insert. any ideas? I'm usin...
