This is a harder problem than it might at first appear, since you need to consider comment tokens inside strings, comment tokens that are themselves commented out etc.

This is called a [Reservoir Sampling][1] problem. The simple solution is to assign a random number to each element of the list as you see it, then keep the top (or bottom) k elements as ordered by the random number.

You could do it yourself. Some MMS companies just have a SOAP API that you can call. All you need to do is construct the XML and send it off via a URL. I have done this once before, but can't remember the name of the company I used. |

I don't believe there is any easy way to make a Windows Installer project have the ease or upgradability of ClickOnce. I use ClickOnce for all the internal .NET apps I develop (with the exception of Console Apps). I find that in an enterprise environment, the ease of deployment outweighs the lack of flexibility. |

Nope. The reason ActiveX can do it is because ActiveX is a little application that runs on the client's machine.

I don't know about other flavors but MySQL [DELETE](http://dev.mysql.com/doc/refman/5.0/en/delete.html) allows LIMIT.
If you could order things so that the n rows you want to keep are at the bottom, then you could do a DELETE FROM table LIMIT tablecount-n.

If you ever receive values at the maximum or minimum, then you are, by definition, clipping. Those values represent their particular value as well as all values beyond, and so they are best used as outside bounds detectors.
