Returns an expression that has been converted to a Variant of subtype Boolean.
The expression argument is any valid expression.
If expression is zero, False is returned; otherwise, True is returned. If expression can't be interpreted as a numeric value, a run-time error occurs.
The following example uses the CBool function to convert an expression to a Boolean. If the expression evaluates to a nonzero value, CBool returns True; otherwise, it returns False.
Dim A, B, Check A = 5: B = 5 ' Initialize variables. Check =
CBool(A = B
)' Check contains True. A = 0 ' Define variable. Check =
)' Check contains False.
