CBool Function

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 = CBool(A)       ' Check contains False.
