i want to discuss a scenario. what is the best way to send bulk emails with asp.net. like reminder emails. emails to all members of forum. or send news letters like that also send scheduled emails.

i have three scenarios in my mind. i need experts suggestions for these.

1) Run a loop  in code to send number of email


 for (i=0; i<= table.Rows.Count ; i++)

By introducing the concepts of security objects and rules, the .NET Framework 2.0 allows developers to manipulate security settings of objects in a few easy steps using managed code.

Code Name WinFS: Revolutionary File Storage System Lets Users Search and Manage Files Based on Conte


One of the monumental problems organizations face today is aggregating information that's stored in disparate formats. Knowledge workers have long wanted to be able to search for content independent of format. The next version of the Windows operating system, code-named "Longhorn," boasts a new storage subsystem that makes that task easier. That subsystem, code-named "WinFS," allows the user to perform searches based on the metadata of the stored item, regardless of what type of file it is or which application created it. This article covers the basic architecture of WinFS and explains how to use the WinFS managed API.
