Accessing Outlook using VB

Hi,
I need some help on the Outlook. As I was only a beginner on VB, so i was lost. Please Help me... Pls..... =)

I need to update info like contacts , calender retrieve from DB and update to the user's ms outlook.

I have to let the user access thru the Net so i was required to use ActiveX.
I can retrieve the data frm DB using ActiveX but i don't know how to update to the Outlook.

i know need to use Outlook.Application..... but i was helpless coz i don't know how to use....

so Can u help??
Really appreciate it... =)

This will add an item to your contact list:

Code:

---

Option Explicit
Dim oOutlook As New Outlook.Application

Private Sub cmdAdd_Click()
    Dim oContact As Outlook.ContactItem
    With oOutlook
        Set oContact = .CreateItem(olContactItem)
            With oContact
                .FirstName = txtFirst.Text & ""
                .LastName = txtLast.Text & ""
                .HomeAddressStreet = txtAddress.Text & ""
                .HomeAddressCity = txtCity.Text & ""
                .HomeAddressState = txtState.Text & ""
                .HomeAddressPostalCode = txtZip.Text & ""
                .Save
            End With
    End With
    Set oContact = Nothing
