From the Code window, select 'Form'. The Private Sub 'Form_Load()' will be displayed now.
In the 'Form Load' function, create the GSM objects in the following way:

   Dim objMessageDB As AXMMCFGLib.XMessageDB
   Dim objConstants As AXMMCFGLib.XConstants

Step 4: Send an SMS Message

The following code shows how to send an SMS message:

Dim objMessageDB As AXMMCFGLib.XMessageDB
Dim objConstants As AXMMCFGLib.XConstants

Private Sub Command1_Click()
    objMessageDB.Open
    PrintResult ("Open")
    CreateSmsMessage (strRecipient)
    objMessageDB.Close
      
End Sub


Private Sub Form_Load()
    Set objMessageDB = CreateObject("AxMmServer.MessageDB")
    Set objConstants = CreateObject("AxMmServer.Constants")
End Sub


Private Sub PrintResult(strFunction)
    MsgBox strFunction & ", result: " & objMessageDB.LastError & " (" & objMessageDB.GetErrorDescription(objMessageDB.LastError) & ")"
End Sub


Function CreateSmsMessage(strRecipient)

   Dim objMessage
   ' Create new message in the Message Database
   Set objMessage = objMessageDB.Create
   PrintResult ("Create")
   If (objMessageDB.LastError <> 0) Then
      CreateSmsMessage = 0
      Exit Function
   End If
  
   MsgBox "Message successfully created, recordID: " & objMessage.ID

   objMessage.Direction = objConstants.MESSAGEDIRECTION_OUT
   objMessage.Type = objConstants.MESSAGETYPE_SMS
   objMessage.Status = objConstants.MESSAGESTATUS_PENDING
   objMessage.ChannelID = 0     ' First available SMS channel
   objMessage.ScheduledTime = "" ' To indicate immediate schedule.
                                ' To schedule 1 day and 2 hours in advance, specify "+1d2h0m"
                                ' To schedule on specific date/time, specify 12/25/2005 07:30

   objMessage.Recipient = TextRecipient.Text
   objMessage.Body = TextMessage.Text

   ' Save the new values that were just assigned
   objMessageDB.Save objMessage
   PrintResult ("Save")
   If (objMessageDB.LastError <> 0) Then
      CreateSmsMessage = 0
      Exit Function
   End If

   CreateSmsMessage = objMessage.ID
