Remarks: VBScript CBool Function

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.
