Appendix C. Constants and Enumerations

This appendix consists of a reference for Visual Basic's built-in constants and enumerations.

Visual Basic 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, you can use the following expressions in VB code:

     CompareMethod.Binary     CompareMethod.Text 

Visual Basic also defines two equivalent built-in constants in the Constants class of the Microsoft.VisualBasic namespace that serve the same purpose:

     vbBinaryCompare     vbTextCompare 

While this is convenient, VB does not define built-in constants corresponding to every member of every enumeration. For instance, there are no built-in constants that correspond to the OpenMode enumeration members, used with the FileOpen procedure:

     Enum OpenMode        Input = 1        Output = 2        Random = 4        Append = 8        Binary = 32     End Enum
