的解決方案是簡單的（從數據庫中刪除之後）。刪除後，再次加載組合框中的數據..

Private Sub btn_remove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_remove.Click 
    Dim Query As String 
    mysqlconn.Open() 
    Query = "delete from table where screen_id='" & cmb_id.Text & "' " 
    Dim cmd As MySqlCommand = New MySqlCommand(Query, mysqlconn) 
    Dim i As Integer = cmd.ExecuteNonQuery() 
    If (i > 0) Then 
     MsgBox("Record is Successfully deleted") 
**===> load the data here or call the function that load the data in the combo box** 
    Else 
     MsgBox("Record is not deleted") 
    End If 
    mysqlconn.Close() 
End Sub
