Hi,

Does anyone know of any good references (web or books) about an overview of architecture design (vb .net and vb6). I am looking to develop an application with a VB .net front end and an SQL back end. I need to find examples of business layers/data layers etc.

I have an idea of the conceptual ideas, but am having trouble implementing them. How do i go about designing classes for just collecting data from the db/building business objects/user interface etc.

Any references links are welcome.

Sorry if the question is a little muddled, but its difficult to know what to ask for when your not sure yourself!

Thanks

AArnie.

VB design patterns by cooper is a fantastic book.  Here's a link about it:
http://visualbasic.about.com/library/blcooper1-1a.htm


I did a search on the web, but could not find much for just VB or VB.Net.

However, if you what some high level definitions, or if you understand a little Java, C++, or C# do a search in google for something like:

UML Design Patterns C#


and you will get a ton of pages.

Here is a MS page where you can download a definitive collection of differences between VB.Net and C# white paper (8-10 pages).

I would reccomend googling "UML Design Patterns C#" and downloading those white papers.  There are litterlly thousands of pages devoted to C# design patterns and the white paper would be a good translation guide for you.

by the way... if you have a choice, go with a VB.Net book instead of a VB 6 book.

VB 6 claims to be object oriented, but it's not really.  Sure it lets you create user defined objects and lets you creted pseudo instances of them, but VB6 does not support inheritance or real sound object design methodologies.  

While any VB6 book would usefull... it will always be missing certain pieces that you decide you can't live without.
