Single label to show multiple text from db

Hi there, Im developing a project in that im displaying the value from the ms access to one label... But its updating only the last value if i use while (rd.read()) and gives me first value for if(rd.read())

my question is how to display that db datas one by one in the single label and the text should have timmer control while changing.. The label.text should change for every 5secs with db values!
