What I need to do is take the 1 Groupbox and at runtime create multiple Groupboxes to display based on user selection. Instead of dynamically creating the Groupboxes ...
MS Entity Framework VS NHibernate and its derived contribs (FluentNHibernate, Linq for NHibernate)
I just read this article about the Entity Framework 4 (actually version 2). Entity Framework seems to offer a huge improvement over its first release. Thus, I have never ever used EF in any project, since I think EF is not mature enough in comparison to NHibernate. NHibernate and its current contributions of FluentNHibernate and Linq f...
What would be the equivalent VB.NET code for this C# FluentNHibernate component mapping?
I'm a C# programmer constrained to write VB.NET code. While exploring NHibernate further for my current client, I encountered FluentNHibernate, which I find real attractive. But now, I wonder how to "translate" this C# code for component mapping into VB.NET code: Component(x => x.Address, m => { m.Map(x => x.Number); m.Map(x =...

Threads Question
I have tried to implement a multithreaded crawler and it seems to be working in fetching a list or urls concurrently without any issues. I tested each step and had the program write all html pulled to a text file. Now the rest of the program intends to take each html stored as a string and parse it for a list of urls from that page and ...
"Target Framework" in Visual Studio
What actually happens when you target the .NET 3.5 framework in Visual Studio? What does that actually do? Does it somehow "flag" any of the output files and associate them with the framework version? ...
What constructs/patterns do you use for accessing state?
Let's say you're building something simple, like a data entry/CRUD form for working on an entity called Customer. Maybe you pass the CustomerID in via Session state. I tend to write a lot of fairly boilerplate plumbing code around handling that Session variable in a particular way. The goals vary slightly but tend to be things like: A...
Placing the same ASP.NET control in different areas of a page.
I have some code that I've inherited, and it's not the greatest in the world, but it works, with one small exception: This page is a directory search, it has controls identified by record ID, however there exists a situation where there can be more than one result with the same record ID, thus making .NET barf. I had originally impleme...
Project will not start in debug mode.
I'm using VS2008, and I have a project that will not start when I press F5 or when I click the little green triangle in the toolbar. The screen flickers once, like the project is going to run, and then it doesn't. The build message claims the build was successful, but the project won't start. In the Configuration Manager, my 'Active s...

VB.NET - Weird String Error!?
Hey guys, I'm making a SIMPLE, and when I mean simple, I mean simple. But any way, I have this thing where, the person enters in a word, and it will preview a text file.

I have a method name "LogClick" that is called 2 or more times per second. I call it in the tradicional way: Call New MyClass().LogClick() Everty time I call "LogClick", the "MyClass" is instanciated. So I think: "why not transform this method to shared?"
