Standardized Naming Conventions for Visual Basic .NET

When you’re programming, names are important. If you’re programming with Visual Basic .NET, the following table can be a major help in getting the names right. It gives the common prefix to use when naming objects so you can quickly tell your check boxes from your combo boxes and your radio buttons from your record sets.
