I guess Blowfish is not included in .net class library.how to implement it,,there are any sample code.? ive already try but still have a trouble to encrypt data without padding.

View 3 RepliesWe have a vb.net application where we have implemented multithreading. We determined that we need to either implement .net remoting or WCF. After researching remoting in .NET on MSDN, Microsoft considers remoting legacy for .NET framework 4.0 and recommends using WCF instead. My question is: can we implement WCF functionality into our VB.NET application or do we need to rewrite the app from the ground up in WCF?

I am implementing a tracing mechanism myself. Now what I'd like to know is what is the best way to implement this mechanism(I mean, the architecture).[code]But then I saw there is an TraceListener class that let's me implement Write and WriteLine methods. The big drawback is that both those methods allow only strings as arguments, and I'd want to be able to send a lot more info than strings. What should I do? Maybe my first ideia is the best?I do know there are a lot of tracing mechanisms like PostSharp and so, I'm just doing this for learning purposes!

In .net (c# or vb) expressions, how would you implement SQL's handy IN() functionality?i.e. value in (1, 2, 4, 7)rather than:
value = 1 or value = 2 or value = 4 or value = 7
There are obviously many ways, I'm looking for the most clean and simple!
What is the best practice for when to implement IDisposable? Is the best rule of thumb to implement it if you have one managed object in the class, or does it depend if the object was created in the class or just passed in? Should I also do it for classes with no managed objects at all?

I am creating a program that will send large files from a server to several clients periodically. I would like to use some sort of Torrent functionality, meaning that I want the clients to sync the information between each other as well as from the server. If client1 downloads part 1, client2 part 2 and so on, I want them to download the rest of the partial files from each other instead of the server. Are there any libraries for .net that can accomplish this? I do NOT want to use a third party tool like uTorrent, but write the actual functionality myself.

I have a MenuStrip control and when I right clicked on it and selected "insert standard items", it created a few functions. There are a few options there that I would like to get working: Cut, Copy, Paste, Delete, and Select All. I presume that for what I want, I'd need to make my own classes for each function. (ie: Cut class, Copy class... etc.)
I would like to be able to do something similar to the example below:

First the requirements: By management requirements, I can't use open source code. I need the users to define their own formulas for a project. My users don't know how to code. The formulas need to be saved somehow, and being read later. I need to debug the formulas written, so I need to be able to see and understand them. The formulas used are quite specialized and specific (actuarial formulas). Adding new formulas (functionality) must be done in fast and maintainable way.

View 5 RepliesI am trying to figure out the best way to implement a certain part of my model.I have an entity named Customer which has CustomerLocations (1-*) which have SalesOrders (1-*) which have Invoices (1-*).I want to allow them to have multiple addresses (Billing and Shipping) per customer and per location. I want to store those values in the sales orders and invoices, not a foreign key, what if they delete one of their addresses later down the road.I have tried complex types, but then they can't have multiple, can they? And having an Address entity, customer --> address (1-*) is ok, but a bit clumsy. How would you have a collection of billing and shipping addresses.?
