Automaticly Dialing a DUN connection??

Hi,
I'm using JMailer to send a simple e-mail but the user of my app won't have a permanent connection to the net. Is there some code any of you could suggest that will allow me to automaticly dial a DUN connection when the user clicks on the send button? (Preferably also giving the user a chance to disconnect after the e-mail has been sent as well.) Thanks,

Rhys

To automatically connect to the net:

Private Sub Command1_Click()
Dim X
'"ConnectionsName" is the name under the icon in Dial-up Networking
X = Shell("rundll32.exe rnaui.dll,RnaDial " & "ConnectionsName", 1)
DoEvents
'You can type in your password before the { below.
SendKeys "{enter}", True
DoEvents
End Sub

To disconnect:

Public Const RAS_MAXENTRYNAME As Integer = 256
Public Const RAS_MAXDEVICETYPE As Integer = 16
Public Const RAS_MAXDEVICENAME As Integer = 128
Public Const RAS_RASCONNSIZE As Integer = 412
Public Const ERROR_SUCCESS = 0&

Public Type RasEntryName
    dwSize As Long
    szEntryName(RAS_MAXENTRYNAME) As Byte
End Type

Public Type RasConn
    dwSize As Long
    hRasConn As Long
    szEntryName(RAS_MAXENTRYNAME) As Byte
    szDeviceType(RAS_MAXDEVICETYPE) As Byte
    szDeviceName(RAS_MAXDEVICENAME) As Byte
End Type

Public Declare Function RasEnumConnections Lib _
"rasapi32.dll" Alias "RasEnumConnectionsA" (lpRasConn As _
Any, lpcb As Long, lpcConnections As Long) As Long

Public Declare Function RasHangUp Lib "rasapi32.dll" Alias _
"RasHangUpA" (ByVal hRasConn As Long) As Long            
Public gstrISPName As String
Public ReturnCode As Long
            
Procedure
Public Sub HangUp()
Dim i As Long
Dim lpRasConn(255) As RasConn
Dim lpcb As Long
Dim lpcConnections As Long
Dim hRasConn As Long
lpRasConn(0).dwSize = RAS_RASCONNSIZE
lpcb = RAS_MAXENTRYNAME * lpRasConn(0).dwSize
lpcConnections = 0
ReturnCode = RasEnumConnections(lpRasConn(0), lpcb, _
lpcConnections)

If ReturnCode = ERROR_SUCCESS Then
    For i = 0 To lpcConnections - 1
        If Trim(ByteToString(lpRasConn(i).szEntryName)) _
            = Trim(gstrISPName) Then
            hRasConn = lpRasConn(i).hRasConn
            ReturnCode = RasHangUp(ByVal hRasConn)
        End If
    Next i
End If

End Sub

Public Function ByteToString(bytString() As Byte) As String
Dim i As Integer
ByteToString = ""
i = 0
While bytString(i) = 0&
ByteToString = ByteToString & Chr(bytString(i))
i = i + 1
Wend
End Function

Usage

Call HangUp

I can connect with that code so thanks for that, but when I try and disconnect I get the error 'User-defined type not defined'. It doesn't like this line: lpRasConn(255) As RasConn.

I could might have put something where it dosn't belong. As you may have gathered I'm quite new to API and stuff like that! Any suggestions?

Here are the tips you need:

ummm, don't been to be stupid - but what's meant to go where that smiley is?

I don't see no smiley man!? I am crazy or just drunk?

Anyway:

look there for all the smileys.

Ok, I think I must be doing something wrong. Out of the following code, whaht goes in a module and what goes into the form code ??? This is driving me insane!

P.S
I also can't understand the <code> tags as well so forgive me for the unformatted code!

Const RAS_MAXENTRYNAME = 256
Const RAS_MAXDEVICETYPE = 16
Const RAS_MAXDEVICENAME = 128
Const RAS_RASCONNSIZE = 412

Private Type RasEntryName
dwSize As Long
szEntryName(RAS_MAXENTRYNAME) As Byte
End Type
Private Type RasConn
dwSize As Long
hRasConn As Long
szEntryName(RAS_MAXENTRYNAME) As Byte
szDeviceType(RAS_MAXDEVICETYPE) As Byte
szDeviceName(RAS_MAXDEVICENAME) As Byte
End Type

Private Declare Function RasEnumConnections Lib "rasapi32.dll" Alias "RasEnumConnectionsA" (lpRasConn As Any, lpcb As Long, lpcConnections As Long) As Long
Private Declare Function RasHangUp Lib "rasapi32.dll" Alias "RasHangUpA" (ByVal hRasConn As Long) As Long
Sub HangUp()
Dim i As Long
Dim lpRasConn(255) As RasConn
Dim lpcb As Long
Dim lpcConnections As Long
Dim hRasConn As Long
lpRasConn(0).dwSize = RAS_RASCONNSIZE
lpcb = RAS_MAXENTRYNAME * lpRasConn(0).dwSize
lpcConnections = 0
ReturnCode = RasEnumConnections(lpRasConn(0), lpcb, lpcConnections)

If ReturnCode = ERROR_SUCCESS Then
For i = 0 To lpcConnections - 1
If Trim(CStr(lpRasConn(i).szEntryName)) = Trim(gstrispname) Then
hRasConn = lpRasConn(i).hRasConn
ReturnCode = RasHangUp(ByVal hRasConn)
End If
Next i
End If
End Sub

Looking at all the private statement I would say it has to be placed in a module.
Did you use

Private Sub Command1_click()
Call HangUp
End Sub

in your form?

I can't test it because I have cable.
Anyway, for the formatting use
[code] My code goed here [/code]

I tried putting all the code into a module and calling the 'HangUp' sub but I still get the same error. I've tried putting the HangUp sub in the form code and calling it from there, but again, I get the same error. Is there anyone with a dial-up networking connection that could try this?
