| <p>You shouldn't have to parse an ICS just to import it into Google Calendar, it is capable of importing them directly... From the end-user's web view, it's as easy as clicking Import Calendar.

<p>Does anyone have a good way of implementing something like a sequence in SQL server?</p>
<p>Sometimes you just don't want to use a GUID, besides the fact that they are ugly as heck. Maybe the sequence you want isn't numeric? Besides, inserting a row and then asking the DB what the number is just seems so hackish.<... | <p>Sql Server 2012 has introduced <a href="http://msdn.microsoft.com/en-us/library/ff878058.aspx" rel="noreferrer"><code>SEQUENCE</code> objects</a>, which allow you to generate sequential numeric values not associated with any table.</p>
<p>Creating them are easy:</p>

<p>I just created a table with the name of the sequence, current value, & increment amount.</p>
<p>Then I created a 2 procs to add & delete them. And 2 functions to get next, & get current.</p>

<p>I have a <em>huge list</em> of person's full names that I must search in a <em>huge text</em>.</p>

<p>If I'm reading a text file in shared access mode and another process truncates it, what is the easiest way to detect that? (I'm excluding the obvious choice of refreshing a FileInfo object periodically to check its size) Is there some convenient way to capture an event? (Filewatcher?)</p>

| <p>As blowdart said, simple IP Address logging is handled by IIS already. Simply right-click on the Website in Internet Information Services (IIS) Manager tool, go to the Web Site tab, and check the Enable Logging box. You can customize what information is logged also. </p>
