<br />--(no spaces, dashes, slashes, etc. just use numbers)
<br />--Below is the date Dec 12, 2003
<br />Expiration_Date = "20031212"
<br />
<br />--Get the system date in ISO format
<br />--Date = YYYY-MM-DD
<br />Date = System.GetDate(DATE_FMT_ISO);
<br />
<br />--Remove the dashes in the ISO format date
<br />--to reflect the format of our expiry date
<br />--Date == YYYYMMDD
<br />Date = String.Replace(Date, "-", "", false);
<br />
<br />--test to see if the application is expired
<br />if Date > Expiration_Date then
