VB & VBA in a Nutshell: The Language

LBound Function

Syntax

LBound(arrayname[, dimension])

arrayname

Use: Required

Data Type: Any

The name of the array.

dimension

Use: Optional

Data Type: Variant (Long)

A number specifying the dimension of the array.

Return Value

A Long integer.

Description

Determines the lower limit of a specified dimension of an array. The lower boundary is the smallest subscript you can access within the specified array.

Rules at a Glance

• If dimension isn't specified, 1 is assumed. To determine the lower limit of the first dimension of an array, set dimension to 1, 2 for the second, and so on.

• The lower bound of an array dimension can be set using To, Dim, Private, Public, Redim, and Static, and can be set to any integer value.

Programming Tips and Gotchas

• The Option Base statement sets the default lower bound of an array to either 1 or 0.

• An array created with the Array function always has a lower bound of zero.

• The LBound function can't determine the lower limit of a control array. Instead, in both Visual Basic and Visual Basic for Applications, you can use the control array's LBound property to determine its lower limit.
