• Architecture Still unclear on how to use Typed Datasets in BLL...

  OK, I have decided to use typed datasets in my data access layer (DAL). So, my question is, do I really need to create a business logic layer (BLL) From what I have read, you can extend the dataset classes in the DAL using partial classes and place business logic there. Doesn't this combine the DAL and BLL into one component Or is there something I'm missing Do you create the BLL and start by referencing the DAL project and inheriting the classes from the DAL and extend the classes there I don't get where one ends and the other starts. OR, if it really makes a difference. ...or do I even know what I'm talking about...

• SQL Server Special/Foreign Language Characters Issue

  Hi,   We have a package that does a simple table to table data loading. Both source and destination have the same Codepage (850) and collation (SQL_Latin1_General_CP850_CI_AI). However, there are some foreign language characters in the source table, and it gets messed up when it's loaded into the target.   Here's an example for a column with this type of text:   Source: Solut§es Informst Target: Solu■oes Inform t   Both columns are char(30).   I have tried to load this row into another server in a different location and it works just fine, however the original target of data displays the text incorrectly.   I have no idea what can be causing this.   Thanks, ...Show All

• Smart Device Development XP Pro Local Smart Card Logon

  I was wondering why it is not possible to log on to a Windows XP Pro machine locally using a Smart Card. I have looked in the Local Security Settings console and have found this under Local Policies > Security Options. "Interactive logon: Require smart card" It does now state that you have to be on a domain in order for that to work. I have even tried using NetSign to force my system to prompt for Smart Card in order to log on locally but it keeps prompting that there is no smart card present when inserted at the logon screen. I even forced Ctrl+Alt+Del to be pressed to log on and it still prompts for smart card to be inserted even after I have inserted it. Is there any software out there that can force Smart Card to be ...Show All

• Visual Studio 2008 (Pre-release) Support for Group By, Having etc

  How sophisticated are the query capabilities for LINQ. Can a SELECT includes Group Bys, Aggregate Functions, Having Clauses. I have a sophisticated query which runs within the MS Access query designer, but running the same query using .NET OleDb provider results in an error. The query uses joins to selects which have group by and aggregate functions in them. The error message says there is an error in the Syntax after the From clause. So I'm thinking to return result sets back to VB.NET and use LINQ to further process the data into the final result set. The other alternative is use a lot more code to massage the data into the final result set which is going to be nasty. Yes, it can. If you dow ...Show All

• Visual Studio Tools for Office Generate Excel file using ASP.NET

  I am currently working on a page that will generate dynamic reports for my company. These generated reports are building an excel file using C# and the Microsoft.Office.Interop.Excel dll. While most of this works the way I would like it to I have run into one problem. When I use Pictures.Insert() I recieve an error stating that I am not including an assembly reference.
