# CBool Function

Converts a string comparison or numeric comparison to a Boolean expression, or converts a single numeric expression to a Boolean expression.

## Sintakse:

    CBool (Expression1 {= | <> | < | > | <= | >=} Expression2) or CBool (Number)

## Atgrieztā vērtība:

Bool

## Parametri:

Expression1, Expression2: Any string or numeric expressions that you want to compare. If the expressions match, the CBool function returns True, otherwise False is returned.

Number: Any numeric expression that you want to convert. If the expression equals 0, False is returned, otherwise True is returned.

The following example uses the CBool function to evaluate the value that is returned by the Instr function. The function checks if the word "and" is found in the sentence that was entered by the user.

## Piemērs:

    Sub ExampleCBool

    Dim sText As String

        sText = InputBox("Please enter a short sentence:")

        ' Proof if the word »and« appears in the sentence.

        ' Instead of the command line

        ' If Instr(Input, "and")<>0 Then...

        ' the CBool function is applied as follows:

        If CBool(Instr(sText, "and")) Then

            MsgBox "The word »and« appears in the sentence you entered!"

        EndIf

    End Sub
