    I have an sql statement which selects all the information in 3 tables and then takes it in to VB as an object “objRS” see below :-
    Set objConn = New ADODB.Connection
    Set objRS = New ADODB.Recordset
    Dim objErr As ADODB.Error
    Dim check As Boolean
    Dim Check1 As Boolean
    objConn.Open "Driver=SQL Server; Server=BOSS;" & _
    If objConn.State = adStateOpen Then
      'Open a recordset
        objRS.Open "SELECT * FROM Vet, Management, Assistant ", objConn, adOpenForwardOnly, _
                       adLockReadOnly, adCmdText
        Do While Check1 = False
            MsgBox (objRS! M_StaffNo)
            If objRS.EOF Or objRS.BOF Then
                MsgBox "Not Found, Error in Database"
                Check1 = True
                Exit Do
                If S_no.Text = objRS!V_StaffNo Then
                    Frame_Vet.Visible = True
                    Frame_Comments.Visible = True
                    V_Salery.Text = objRS!V_Salery
                    V_Room.Text = objRS!V_Room
                    V_status.Text = objRS!V_status
                    Comment.Text = objRS!V_comments
                    Check1 = True
                End If

The problem here is:- how do I reference information from each table in the query. Is it  objRS!Vet.V_StaffNo or how do I tell the different between the data.

Simply use the name of the field of the table in the recordset object like this:

Also ensure to attach an empty string while assigning any recordset value to a textbox else you might get an error if the value is Null. Example:
 V_Salery.Text = objRS("V_Salery") & ""
