VBFixedArrayAttribute	Indicates that an array in a structure or non-local variable should be treated as a fixed-length array.
VBFixedStringAttribute	Indicates that a string should be treated as if it were fixed length.
VBMath	The VbMath module contains procedures used to perform mathematical operations.

Structs

SpcInfo	This class supports the Visual Basic Print and PrintLine functions.
TabInfo	This class supports the Visual Basic Print and PrintLine functions.

Enums

AppWinStyle	Indicates the window style to use for the invoked program when calling the Shell function.
CallType	Indicates the type of procedure being invoked when calling the CallByName function.
CompareMethod	Indicates how to compare strings when calling comparison functions.
DateFormat	Indicates how to display dates when calling the FormatDateTime function.
DateInterval	Indicates how to determine and format date intervals when calling date-related functions.

FileAttribute	Indicates the file attributes to use when calling file-access functions.
FirstDayOfWeek	Indicates the first day of the week to use when calling date-related functions.
FirstWeekOfYear	Indicates the first week of the year to use when calling date-related functions.
MsgBoxResult	Indicates which button was pressed on a message box, returned by the MsgBox function.
MsgBoxStyle	Indicates which buttons to display when calling the MsgBox function.
OpenAccess	Indicates how to open a file when calling file-access functions.
OpenMode	Indicates how to open a file when calling file-access functions.
OpenShare	Indicates how to open a file when calling file-access functions.
TriState	Indicates a Boolean value or whether the default should be used when calling number-formatting functions.
VariantType	Indicates the type of a variant object, returned by the VarType function.
