VS 2008 Connect A Logic Layer Between Presentation Layer And Data Layer?
Feb 7, 2011I am generally following this tutorial, the main differences being I'm using 2008 R2 Express and Windows Forms, he is using 2005 & ASP.NET Web Site:'m building a minimalist Windows Form project for learning purposes. So I'm using a 1-table database with 2 columns, ContactID & Name. I added a dataset file, 'ContactsDataSet.xsd' to my project and added a single minimalist table adapter with just a fill() & getdata() method.Then I added a DataGridView control and connected it to the ContactsDataSet to confirm it was working and that worked fine. I ran it and it filled up with data as expected. Everything up to this point was auto-generated code.

Jul 27, 2010I build a component class it extends a combo box and generates some random numbers. But when I drag and drop my component from the toolbox to a form it auto generates Me.Randtest1.Items.AddRange(...) in the Designer which uses static numbers. The idea was to have different numbers each time and not the same.[code]

Prevent Data Layer Refactoring Of ODP.NET Code And Transactions?
Aug 27, 2009I am using Oracle 11g client, with ODP.NET. I am trying to add conditional Transaction handling.
Dim ds As New DataSet()
Dim txn As OracleTransaction
Dim _beginTransaction as Bolean = true
Using conn As New OracleConnection(ConnString)
[Code]...
How do I fix txn being nothing / null? The error is: Variable 'txn' is used before it has been assigned a value. A null reference exception could result at runtime. Edit: to RichardOD for pointing out that you can not explicitly declare that a transaction cannot be opend up on stored procedures via ODP.NET. I have verified that this is an issue. BUT We still haven't figured out why the error is occuring. I understand that txn is initially given a value w/in an if statement, but being defined outside of the try/catch block should make that irrelevant.... right? Or is that bad coding?

View 5 RepliesClass - Add A Readonly Property To Layer That Is Calculated Using Some Layer Information?
Nov 30, 2010I am working in VB.NET defining my own classes. I have 5 classes, Policy, Coverage, CoverageCollection, Layer, and LayerCollection. Policy has a bunch of data items, one of which is of type CoverageCollection. Coverage has a bunch of data items, one of which is of type LayerCollection.
Policy
private id as Long
private name as String[code].....
Then I do like "dim p as Policy". So, iIn order to get to properties on a Layer, I reference it like p.cov(0).lyr(0).face. What I am trying to do is add a readonly property to Layer that is calculated using some Layer information but also using something from Coverage (or even Policy). I can take this in as a parameter to the property, but I think there should be a way to get at Coverage/Policy information since I am "under" it already. Is there a way to do this?
VB Code Behind The Business Logic Layer?
Oct 1, 2010I also went though the whole "ASP.Net in 24 Hours" book by Scott Mictchell. I followed everything that went on in that book and built the final project successfully. I also used the tutorials here to better understand the whole Membership Provider/User tables setup that was going on in the book. Next, I thought I would learn more about accessing data for ASP.Net since that is what most application do.I went through the first Data Tutorial here. I seemed to understand what was going on just fine.The second Data Tutorial seemed to just show a lot of VB code to build the Business Logic Layer. There was not much explanation about how to do it yourself.I think I can keep going in the tutorials here. I downloaded the code from the second tutorial and went through it.I am guessing that the code in the second tutorial was given just to proceed with the overall project that is being built throughout the tutorial sequence.

Auto-generate Custom Number For Database In Asp.net Vb
Jan 27, 2012I would like to generate a tracking number as primary key for my database.
There will be total 12 letters for each tracking id. Example: 2012010001-1
The "2012010001-1" is actually from combination YYYYMMxxxx-v where YYYY is the current year, MM is the current month, xxxx is the auto generate number(increment) and -v is the version where it can be -2 -3 but using the same YYYYMMxxxx.
For both YYYYMM is not a prob as i can get the value from Date.Today.Month/Date.Today.Year. But how am I going to ensure the xxxx is an auto increment but will be reset back to 0000 every new month.
For example:
2012010000-1 (Month January, so start from 0000)
2012010001-1
2012010002-1
