Question

Hi,
I am using Excel sheet to metion the "Warrenty Dates"
Issue Date: 01/06/09   and Last Date is 30/06/09.
I have to retrieve  the values from the Excel sheet to "DataGridView".  Just for Date conformations.
When the date is out of date ---Popup some alert information saying that"Your Duration Time over"
May be before one week..It can be only "one week u have  to update "  Like that.
 
Excel sheet colums are
:Item,Money,Issue Date,Expire Date,Duration date.
Can any one help me rgarding this.
