Calling dll from ASP?

Does any one know the syntax for calling the following VB dll in asp i.e. how to send the list of variables? Or how the VB code needs to be changed to be able to be accessed from asp?

Dim conn As ADODB.Connection
Dim strSQL As String
Dim Rst As New ADODB.Recordset

Private Sub ConnectToDb(DSN$, QuerySQL$)

Set conn = New ADODB.Connection
conn.ConnectionString = "Provider=Microsoft.JET.OLEDB.3.51;Data Source=" & DSN$
conn.Open
strSQL = QuerySQL$

Set Rst = conn.Execute(strSQL)

End Sub

Public Sub SendEmails(DSN$, QuerySQL$, ServerName$, FromDisplay$, FromAddress$, MsgSubject$, PlainText$, HTMLFile$)

Dim x%, void%
Dim SMTP As Object

ConnectToDb DSN$, QuerySQL$

Set SMTP = CreateObject("EasyMail.SMTP.5")

SMTP.MailServer = ServerName$

Do While Not Rst.EOF

void% = SMTP.Clear(1 + 2) ' clear recipients and attachments
SMTP.From = FromDisplay$
SMTP.FromAddr = FromAddress$

SMTP.AddRecipient Rst!Name, Rst!email, 1
SMTP.Subject = MsgSubject$

'Set body format to HTML
SMTP.BodyFormat = 1

'Always set AtuoWrap to zero for HTML messages
SMTP.AutoWrap = 0

'Import an HTML file in to the object.
ret = SMTP.ImportBodyTextEx(HTMLFile$, 2 + 4)
If Not ret = 0 Then
Response.Write "Error importing File " & ret
Exit Sub
End If

x% = SMTP.Send
If x% = 0 Then
Debug.Print "Message sent successfully to " & Rst!email
Else
Debug.Print "There was an error sending your message to " & Rst!email & ". Error: " & CStr(x%)
End If

'CallEasyMail ServerName$, FromDisplay$, FromAddress$, Rst!email, MsgSubject$, PlainText$, HTMLFile$
Rst.MoveNext
Loop

Set SMTP = Nothing

End Sub

Many thanks
