This appendix consists of a reference for Visual Basic's built-in constants and enumerations. VB.NET defines several enumerations in the Microsoft.VisualBasic namespace. For instance, the CompareMethod enumeration is defined as: Enum CompareMethod Binary = 0 Text = 1 End Enum Thus, we can use the following expressions in our VB code: CompareMethod.Binary CompareMethod.Text On the other hand, VB also defines two equivalent built-in constants in the Constants class of the Microsoft.VisualBasic namespace that serve the same purpose: VbBinaryCompare VbTextCompare Note, however, that VB does not define built-in constants corresponding to every member of every enum. For instance, there are no built-in constants that correspond to the OpenMode enum members . This enum is used in the FileOpen procedure/statement: Enum OpenMode Input = 1 Output = 2 Random = 4 Append = 8 Binary = 32 End Enum In this appendix, we list all of the VB constants and enumerations. |
