[AccessD] OT Visual basic Express 2012 - ComboBox

To all,

I have only really developed in MS Access and Visual Basic 6.0....I am on a
learning curve at work where we have Visual Studio Express 2012 installed
on my machine. I have the following code to populate a combobox :

Dim adtRequestCodes As New SqlDataAdapter()
Dim dsRequestCodes As New DataSet()
Try
            Dim cmdPIPRequestCodes As New SqlCommand()
            cmdPIPRequestCodes.Connection = pADOPIPConn
            cmdPIPRequestCodes.CommandText = "phPIP_RequestCodes"
            cmdPIPRequestCodes.CommandType = CommandType.StoredProcedure
            adtRequestCodes.SelectCommand = cmdPIPRequestCodes
            adtRequestCodes.Fill(dsRequestCodes)
            adtRequestCodes.Dispose()
            cmdPIPRequestCodes.Dispose()
            Me.cmbRequestCodes.DataSource = dsRequestCodes.Tables(0)
            Me.cmbRequestCodes.ValueMember = "ReasonID"
            Me.cmbRequestCodes.DisplayMember = "ReasonCode"
Catch ex As Exception
            MsgBox(ex.Message)
End Try

This works as it populates the ComboBox.  However I have datatable called
tblPIPRequests which I use to populate textboxes with data using something
like '

Me.txtResolvedBy.DataBindings.Add("Text", tblPIPRequests, "ResolvedByName")
'.  But can't figure out how to have the combobox show the value of
RequestCode from the datatable

I.e. in the datatable 'tblPIPRequests' say the 'RequestCode' is 4 I need
the combobox to show the 'ReasonCode' associated with RequestCode 4 which
would be 'Incorrect Desription'


It may even be that I have set this all up wrong for what I need, I have
been googling here and there just to get where I am now.

Any help GREATLY appreciated.
