This Saturday (2/27) I will be giving my .NET Generics talk for the UT Dallas .NET UG in Richardson TX. If you are in the area please check it out (http://www.usergroupsupportservices.com/UGEventView.ugss?EventID=9160). If you cannot make it but are interested in seeing the talk, you can watch it online.
Generics let you tailor a method, class, structure, or interface to the precise data type it acts upon. In this session we will discuss what capabilities Generics provide to you the developer and how to use them in collections, and with delegates. We will also talk about creating your own generic classes and...
Got a call today, someone was getting a stack dump every time they tried to assign a value to a property. Here is a screen print of the problem they were having. can you spot the problem? If you said that the property is calling itself you get a gold star. What was happening is that every time we tried to set the Name property, it calls the Name property to set it, and that called the Name property, and that called the Name property, over and over again, till .NET stack dumped. We are missing a...
Got a question on how to populate a generic list in VB.NET, and while I am a C# guy, I figured I would show some VB.NET love. For this example I will be using a customer class, he is real simple just 2 properties. One for first name and one for last name. 1: Public Class Customer
3: Private _first_name As String

My colleague, Jerome Nicolas, found a solution the problem outlined below and since he doesn't have a blog and we thought this was some great information we decided to post it to mine. Hope it helps. Scenario: adding a web reference in Visual Studio to an SAP web service that was created from a remotely enabled function module with a table parameter associated type BAPIRET2. Problem: The ABAP object BAPIRET2 is typically used to return messages when calling a BAPI, but it contains a field named “SYSTEM” which can conflict with the System namespace in .NET. If you...
I know that most of you all know this already, but I figured it was worth a blog post since I just saw this from http://www.autosite.com. I got this very informative error message back when using their site earlier. . .

A few weeks ago I got a copy of Professional DotNetNuke 5: Open Source Web Application Framework for ASP.NET (http://www.amazon.com/Professional-DotNetNuke-Application-Framework-ASP-NET/dp/0470438703/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1235867832&sr=8-1). Figured since I had been to presentations by 3 of the 5 authors I just had to have the book. Brian Scarbeau, Stan Schultes and Ryan Morgan are avid speakers in the Florida .NET community and knowing them I knew this book was going to be a good read. A cross country flight from Dallas Texas to Seattle Washington provided the perfect opportunity to concentrate on reading a new book.
While waiting for my plane to take off I made...
Ever wanted access to that treasure trove of information available in SharePoint lists scattered across your enterprise? Ever wanted to provide a quick and dirty UI for users to enter data, but need to have programmatic access to the data? Use SharePoint! SharePoint provides WebServices that give you access to just about everything you can think of (http://msdn.microsoft.com/en-us/library/ms954015.aspx). For the purposes of this article I am going to use the Lists WebService to 1) get data from a list, 2) Add an item to the list and 3) Delete an item from the list.
The first step is to add...
