Cloning a DataRow
I can't even tell you how many times over the last few years I have had to clone a row from one DataTable to another DataTable. To make this easier, I created a method that I can call at anytime to create this new DataRow and return a new DataTable back to me. I have another overload of this method that I can also pass in the new DataTable. In ADO.NET there is no easy way to take a single row from an existing DataTable and copy it to another DataTable. The major reason why it is not so easy is you can not add a DataRow that exists in one DataTable to another DataTable. As a result you must create a new DataRow object and copy all of the values from the original DataRow into this new one. You can then create a new DataTable (or use one with the same structure), and add that DataRow to that new DataTable. Below is a method that you can call to accomplish the copying of a single row from one DataTable to a new DataTable.

Why you Should Move to WPF
If you have not taken a look at WPF yet, you really should. WPF is a great desktop development platform. Granted all of the of the tools are not yet in place, but Microsoft is pouring millions of dollars into developing WPF tools. Windows Forms is now considered a legacy technology and will no longer be updated. These two reasons alone are enough to convince you that you should start taking a little more than a serious look at WPF.

Why Do I Need OOP?
Most developers have been doing some form of Object Oriented Programming (OOP) for quite awhile now. Sometimes you might not even realize it. If you have been using VB 6 for example, then every control is a class, and you interact with it as an object by setting properties and calling methods on those objects. All you need to do now is to start creating your own classes, properties and methods.
