.Net 2.0 Web application using Vb.net is unable to create object of another dll writen in C# .net 2.0
I habe created one ASP.net web application using Vb.net which is adding reference of dlls written in C# and .net 2.0. But whenever trying to create object of referencing dll, it is throwing error :Object reference does not set to an object. But, locally it is working fine,. In the server i have deployed the .aspx files and dll files in the bin. There were already an web.config in the server which is of .net 1.1. But checked it is retrieving value for that web.config correctly.
Should i have to deply any other files and if not what can be the solution for this? Please help.

If you are doing windows development, i would suggest using 'DataForm wizard' (Use Solution Explorer-->Rightclick project-->Add new Item-->New DataForm). It will guide you through steps. If you are doing web apps. Use quickstart to learn them.

Matisse Software Inc. provides its native ADO.NET Data provider for Matisse 6.0, the Database for .NET. Matisse Software has pushed the envelope of Microsoft ADO.NET architecture and extended it into a powerful Object Access Services component for .NET.
Matisse’s extension of ADO.NET demonstrates that ADO.NET can evolve beyond the Microsoft architecture to benefit .NET developers. Unlike the standard ADO.NET data provider, which returns data in a table format to integrate seamlessly with relational products, Matisse has extended the ADO.NET architecture to return data in an object format....optional to use ADO.NET for data access
I've read somewhere that it is optional to use ADO.NET for data access. Is this true?
I find it hard to grasp. In one tutorial, on the asp.net website (http://www.asp.net/learn/videos/), there is a lesson about databinding (lesson 7) where it can retrieve data without ADO.NET...
I think this is just a matter of semantics. When you databind from a source in the way they show there, you don't have to go through the effort of creating the command object, reading its data and manually plugging the data into whatever rendering control you are using, you simply databin...ODP.NET

What is the best way of creating datasets for asp.net pages and populating web form objects. I have always created datasets within a sub routine and then populated my web form controls from that dataset. I was given some code that the pages were created in visual studio. I know the page gets its data from a stored procedure. What I can't find is code that calls that stored procedure and also populates the web form objects. Most of my asp.net development has been done on the asp.net page and not in Visual Studio. So if someone could tell me what to look for that would be great.

How to use Web Developer Express or VB.Net to access data from Fox Pro
I am going through the elementary tutorials in Web Developer Express and database tutorials using SQL 2005 Express. All of a sudden, a friend asks whether we can use the VB.net and Web Developer to access data from Fox pro tables, process the data and save them in Word or Excel and then convert them into PDF documents to send out via the email.
I would appreciate it if someone could enlighten me on the first part first, as I have no experience in using Fox pro at all.

The way I see the design in the most basic forms, that the DAL is referenced in Business Logic Layer, where data returned by the entities is stored in a class.That class is referenced by both the UI and BLL. Right? There is no other way to do it I think, because the moment you let the developer reference the entity in UI, then you lose the separation of data.ORRRRRRRRR maybe there is a way to return an Entity Type to UI from BLL without referencing the DAL?BTW I've searched the web, not much there, as I think relatively few systems have yet to take advantage of this technology this deepl...System.Data, Is ADO.NET is the best way to access data
Can any one give me simple example on how to open a cursor to get data and field names and types.
Is this the best way?
The System.Data namespace provides access to classes that represent the ADO.NET architecture. ADO.NET lets you build components that efficiently manage data from multiple data sources.
Is this a good example. Is this efficient? How do I also print the field names? Please help
