New Product - NoiseMaker

We are introducing a new product called NoiseMaker. It promises to be the best audio multimedia library for Visual Basic developers. Some of the features are:

It will be available in May 1998. For the next three weeks we will be taking pre-orders for only $29.95 for run-time DLL's and $129.95 for complete source code (of course you won't be charged until it ships). After this initial offering the price will increase to $49.95 and $199.95 respectively. The first version of this product will require Visual Basic 5. If you are interested, please email noise@codeoftheweek.com and we will provide complete details on placing your order.


Requirements for this Issue

The source code in this issue is designed for Visual Basic 5.0 and higher. It will probably work in VB4 32-bit with some minor changes.

In this Issue

This issue will introduce some methods for using the Dial-Up Networking features of Windows 95 and NT. This issue assumes you have received Part 1. If you haven't, you can get Part 1 by subscribing to Code of the Week. Jump to http://www.codeoftheweek.com for complete details.

DialUpNetworking Class Module

Description

This module uses a couple of API calls in RASAPI32.DLL to use the Dial-Up Networking (DUN) features of Windows 95/NT. In the previous issue we showed how to make a connection and hang up a connection. This issue we will cover how to retrieve the list of available phone book entries which are available to call.

We will probably have at least two additional parts to this series. One will show how to make a call and retrieve the status as the call is being made. The other will show how to retrieve the username, password, phone number and other properties of a phone entry.

Declaration

Public Function GetEntries(List As Variant) As Boolean

Parameters

Returns

Nothing is returned upon a successful call, except that GetEntriesl will return True. If GetEntries returns False you can use the ErrorMessage function to retrieve the appropriate error (NOTE: ErrorMessage was introduced in Part 1 of this series).

Sample Usage

The below examples show two ways to get the DUN phone entries.

    Dim DUN As New DialUpNetworking

    ' This call will return a list of dial-up networking entries in the array sEntries
    Dim sEntries() As String
    DUN.GetEntries sEntries

    ' This example assumes you have a combobox called cmbEntries on a form.
    ' When GetEntries returns it will have filled your combobox with the
    ' Available DUN entries.
    DUN.GetEntries cmbEntries
