VBScript in a Nutshell, 2nd Edition

Appendix B. VBScript Constants

What follows is a series of tables listing the intrinsic constants supported by VBScript and their values. Note that, because the constants are part of the VBScript language, you don’t have to define them using the Const statement.

Color Constants

These constants represent the values returned by RGB for standard colors:

Constant	Value	Description
vbBlack	0	Black
vbRed	255	Red
vbGreen	65280	Green
vbYellow	65535	Yellow
vbBlue	16,711,680	Blue
vbMagenta	16,711,935	Magenta
vbCyan	16,776,960	Cyan
vbWhite	16,777,215	White

Comparison Constants

The comparison constants are used by a number of functions (Filter, StrComp, Split, and Replace), as well as by the CompareMode property of the Dictionary object, to determine whether astring comparison should be case-sensitive or not:

Constant	Value	Description
vbBinaryCompare	0	Binary (case-sensitive comparison)
vbTextCompare	1	Text (case-insensitive comparison)
vbDatabaseCompare	2	Database (unused in VBScript)

Date and Time Constants

A number of functions (DateDiff, DatePart, Weekday, and WeekdayName) have a FirstDayOfWeek parameter whose value can be one of the day of the week constants (vbSunday through vbSaturday) as well as vbUseSystemDayOfWeek.

The DateDiff and DatePart functions also have a FirstWeekOfYear parameter whose value can be vbUseSystem, vbFirstJan1, vbFirstFourDays, or vbFirstFullWeek.

Constant	Value	Description
vbSunday	1	Sunday
vbMonday	2	Monday
vbTuesday	3	Tuesday
vbWednesday	4	Wednesday
vbThursday	5	Thursday
