Windows 2008 的 SMTP 寄信時若遇到 "Helo command rejected: need fully-qualified hostname" ，可做以下的修改。

The fix is easy:

1. Open IIS
2. View the properties of you Default SMTP Virtual Server
3. Go to the “Delivery” tab
4. Click the “Advanced” button (in the bottom right corner)
5. Under “Fully-qualified domain name” enter a domain name that points to the server
6. Click Ok until you’re back to IIS

DT.Select("Id=" & ProductId) 

'寫入Cache前先設定好

DT.PrimaryKey = New DataColumn() {obj.Columns("Id")} 

Dim row As DataRow = DT.Rows.Find(ProductId)
