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.
This issue will introduce some methods for using the Dial-Up Networking features of Windows 95 and NT.
Part of this issue was submitted by Rick G. from Kansas. Thanks Rick!
This module uses a couple of API calls in RASAPI32.DLL to use the Dial-Up Networking (DUN) features of Windows 95/NT. In future issues we will cover topics on how to retrieve the status of a DUN call and getting lists of available DUN entries.
Public Function Dial(pEntryName As String, pUsername As String, pPassword As String) As Boolean Public Function HangUp() As Boolean Public Function ErrorMessage() As String
Nothing is returned upon a successful call, except that Dial will return True. If Dial returns False you can use the ErrorMessage function to retrieve the appropriate error.
An example that calls a connection named "Internet" with the username "user" and a password "pass"
Dim DUN As New DialUpNetworking
If Not DUN.Dial("Internet", "user", "pass") Then
MsgBox DUN.ErrorMessage
End If
'
' Do something with the connection
'
DUN.HangUp
