Fax VB.NET – Cancel Outbound Fax

The CancelFax method shown in this sample allows you to cancel a previously-submitted, outbound fax using VB.NET. Using CancelFax only effects faxes waiting to be sent (with the status codes: -1 Preprocessing, -2 Ready, or -3 Pending Retry), and not faxes that are being actively transmitted.

The fax VB.NET code snippet below cancels a fax and checks if the cancellation succeeded:

 
Sub Main()
        Dim username As String = "my username"
        Dim password As String = "my password"
        Dim transactionID As Integer = 196805130
        Dim ifws As New interfax.InterFax()
        Dim st As Long = ifws.CancelFax(username, password, transactionID)
        Console.WriteLine("Result is: " & st)
    End Sub
