    Dear Edakad

    You can load your dll if it is registered with the system using CreateObject function.

    Check the following code which is connect with database using VTL

    Note : If you developed your dll using .net check this article

     Public Sub main()
       Dim Connection
       Dim Recordset
       Dim SQL
    'declare the SQL statement that will query the database
    SQL = "SELECT * FROM Test"
    'create an instance of the ADO connection and recordset objects
    Set Connection = CreateObject("ADODB.Connection")
    Set Recordset = CreateObject("ADODB.Recordset")
    'open the connection to the database
    Connection.Open "DSN=Examples_dsn"
    'Open the recordset object executing the SQL statement and return records 
    Recordset.Open SQL,Connection
    'first of all determine whether there are any records 
    If Recordset.EOF Then 
        AlertMessage "No records returned."
    'if there are records then loop through the fields 
        Do While NOT Recordset.Eof   
         AlertMessage Recordset("row")
         AlertMessage Recordset("row2")
    End If
    'close the connection and recordset objects freeing up resources
    Set Recordset=nothing
    Set Connection=nothing
    End Sub
