The new version of Visual Basic, VB7 (or VB.NET), is a big jump from VB6. With VB7 you can use the type library in the .NET Framework, and your applications run on the Microsoft .NET Framework Common Language Runtime (CLR).There are also a number of changes from the previous versions. VB7 now supports inheritance and has a new error-handling mechanism. As part of the .NET Framework, VB7 needs to update the data types for interoperability with other programming languages such as C# and C++, and w...

As we saw starting with the An Overview of Inserting, Updating, and Deleting Data tutorial, the GridView provides built-in support for row-level editing and deleting. With a few clicks of the mouse it is possible to create a rich data modification interface without writing a line of code, so long as you are content with editing and deleting on a per-row basis. However, in certain scenarios this is insufficient and we need to provide users with the ability to edit or delete a batch of records....

Any VB programmer who has moved to VB.NET knows the frustration of losing the ability to create control arrays in a form. VB.NET adds a great amount of flexibility and power, but at the cost of losing some of the features that made VB a great rapid development environment that hid many of the programming details from the developer. One such loss is the control arrays. In the past, you could drop a number of controls on the screen with the same name, and VB took care of creating a member variable...
