I have just got my Gmap control working and have implemented it as part of a form where the user inputs their location for the event they are planning (it's a book club meeting website) and a little google maps preview pops up with their location and the placemarker. I would like to insert the coordinates of the address that they have just entered into the database and retrieve those coordinates at a later date.

I hope someone here is familiar with Subgurim GMap as I'm definitely not!

Anyway here is my client side code:

<p style="text-align:right; margin-right:300px">
    &nbsp;Address:
    <asp:textbox ID="txtStreetAddress" runat="server" Width="150px" /><br />
    Suburb:
    <asp:textbox ID="txtSuburb" runat="server" Width="150px" /><br />
    Country:
    <asp:textbox ID="txtCountry" runat="server" Width="150px" /><br /><br />
    <asp:Button Text="Show On Map" ID="lnkShowMap" runat="server" />
</p>
                <p>
                    &nbsp;<cc1:GMap ID="GMap1" runat="server" GZoom="4" Height="200px" Width="250px" />

And here is my subroutine:

    Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim conn As New OleDb.OleDbConnection(ConfigurationManager.ConnectionStrings("BookMeetConnString").ConnectionString)
        conn.Open()
        Dim cmd As New OleDbCommand("INSERT INTO Events (EventTitle, EventDescription, EventDate, EventCategory, CreatedBy, Coordinates) VALUES (@f1,@f2,@f3,@f4,@f5,@f6)", conn)
        cmd.Parameters.AddWithValue("@f1", tb_eventtitle.Text)
        cmd.Parameters.AddWithValue("@f2", tb_eventdescription.Text)
        cmd.Parameters.AddWithValue("@f3", DateTime.ParseExact(tb_eventdate.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture))
        cmd.Parameters.AddWithValue("@f4", dd_eventcategory.SelectedIndex + 1)
        cmd.Parameters.AddWithValue("@f5", User.Identity.Name)
        cmd.Parameters.AddWithValue("@f6", GMap1.getGMapEleme
        cmd.ExecuteNonQuery()
        conn.Close()
        Response.Redirect("calendar.aspx")
    End Sub

As you can see, I haven't got very far with the Gmap (@f6) parameter. This is where you guys come in!

VB.NET responses preferred!, or error-free C# will suffice as long as I can convert it!

Thanks in advance,
