Re: Converting a DataTable Column to an Array?

First of all why dont you use List.... as your collection. It is always better to use ArrayList or Generic List as collection rather than going for Array.

Next, I always prefer to use ForEach rather than For when I am looping through an Enumerable.

If I was in your situation I would write this as :

Private Function DataTableToArray(ByVal x As DataTable, ByVal intCol As Integer) As List(Of Double)
    Dim lst As New List(Of Double)

    For Each dr As DataRow In x.Rows
        lst.Add(dr.Item(intCol))
    Next

    Return lst
End Function

Or if you still want to use Array you might use List(Of Double).ToArray as well.
Cheers.

Hi, try the following code:

Dim arrValues(0 To intRows - 1) As Double

instead of

Dim arrValues() As Double = New Double(){}

the problem is in mozilla. In IE 7 it works fine.. (though strange thing is it has scrollbar in the left Big Grin | :-D

)

Actually div will not automatically resize in case of Firefox if the content increases. thus the content goes outside the container. Poke tongue | ;-P

Add the clear div in the parent div, this makes the parent div to auto adjust its height.

<br />
<div style="clear: both;"> </div>

Can someone help me to setup properly the IIS?

Many thanks

Thank you both, but I might be missing something and I don't know what I am doing wrong.
On my web.config I am using <authentication mode="Windows">
On the IIS Authentication there are 3 options
- Annonimous (this is the one enabled so far)
- Forms
- ASP.NET

What should I do?

What you are using over web.config. I guess some text is missing over there.

In IIS there should have Windows Authentication. You need to select it.

User.Identity.Name will be null if no user is logged in (depends on the Authentication mode).

ASP.NET Provider and DAL

Good Afternoon,

I am new to ASP.NET. I am used to C# windows delveloper. In all my previous projects we had a seperate solution to handle the Data Access Layer. This layer had all the logic for logging in and communicating with the database.

How do I move the Login (currently I am using Memberships that is setup in my config file) to the DAL layer? Should it be in the DAL layer?

Thanks for all your help.
Chris

Membership having it own internal implementation. If you want to move membership, you can use DAL for all database related code. Even inbetween DAL and UI, you can put the Business Layer also (BLL).

You're trying to keep seperation of concerns, as you should. The problem is, Asp.Net web applications are very much dependant on app and web.configs, which don't run in class libraries.

I don't use .Net Memberships. I created my own role-based security model (did this before I started using .Net) and created data providers to go with it. Also, I use a ConnectionProviderFactory (returns an IDbConnection) class to maintain connection strings so my Dals can be completely independant from the applications using them.

There are some useful features provided in .Net but if you require more abstraction and extensibility you sometimes need to break-out a little.

Hi
Thanks for your input. Smile | :)

Is it really worth going through all the trouble to implement a DAL layer? What is the cons of creating your own role-based security model? And how much work are we talking about. I am fairly new to ASP.NET. Coded alot in VB.NET and C#. When you did this how many stops did you find along the way?

Thanks
Christiaan
