LBound Property
Returns the lowest ordinal value of a control in a control array.
Syntax
object**.LBound**
The object placeholder represents an object expression that evaluates to an object in the Applies To list.
Remarks
The LBound property setting is equal to the Index property value of the first control in the array. Typically this value is 0 because Visual Basic automatically assigns an Index value of 0 to the first control in a control array. If you manually change the Index value for the first control in an array to some other value (for example, 1), LBound returns the value you manually assigned to Index (in this example, 1).
