Following stackoverflow’s example, I’ve started using prettify for syntax highlighting on this blog.  I’ve used the Google syntax highlighter in the past, but prettify just seems easier as I don’t need to mark it with class names or anything – all I need to do is wrap code in <pre> and <code> tags, and it just works.  It’s clever enough to work out the language.

Getting it working was really simple.  I downloaded the source, combined all the .js files into one using Google’s Closure Compiler, and update the .css file to the styles I like (stolen without shame from stackoverflow – I love that site).

To get the styles to apply to my blog, I also added an initialisation script to make the prettify call, and it works.  Hopefully this should save me some time in the future.

I found a really good article here that showed me how to set this all up.  I’ll update old blog posts at some stage, for now they’re going to appear without styling.

.NET – Detecting Modem COM Ports

We have a project at the moment where we’re using GSM modems attached to the local machine to send an SMS.  One of the issues we’ve had is when the modem is not actually connected before our service starts up: our service sometimes attaches to the COM Port that is required by the modem, and this prevents the modem from ever connecting.

There is a simple way to detect which COM ports are assigned to modems installed on your machine:

using System.Management;

ManagementObjectSearcher mos = new ManagementObjectSearcher("SELECT * FROM Win32_POTSModem");
foreach (ManagementObject mo in mos.Get())
    string s= mo["AttachedTo"].ToString();

Other properties available can be looked up here:
