Syntax Highlighting

December 30, 2007 Posted by Jason Irwin No comments

[Edit: The slowdown caused by parsing the main chunk of javascript function was getting out of hand so i temporarily removed formatting from this block. It will now look terribly ugly but i plan to update the formatting mechanism at the weekend to allow collapsed text to be formatted on expansion rather than page-load.

I was recently asked about the code syntax highlighting on my blog. I can't take any credit for it (except for the little time it took me to mash somebody else's code into a single page. The code itself is courtesy of Alex Gorbatchev and is available in it's entirety at under the terms o the GNU Lesser General Public License.

Please beware (if you haven't noticed already) that highlighting big blocks of code requires a relatively large amount of client-side processing, thus slowing the page when loading and causing a little havoc. This, alas, is the nature of the beast. This syntax highlighter allows for a collapsed mode where textareas can be collapsed, thus making things a little neater. Perhaps a nice addition would be deferring the syntax highlighting for a particular region based on whether it is hidden or not....

A syntax highlighter written in Javascript, it allows keywords to be highlighted by creating a textarea, specifying its CSS class (based on the language you wish to highlight) and popping your code into said textarea as follows:

The zip archive download from the above site includes multiple .js and .css files. Since blogger (and most other blogs) only allow for a single HTML page, it was necessary to mash the code from all of these source files together and insert them into this solitary page. I did so as follows (using version 1.5.1):

  1. Compiled all of the Javascript Functions into one script region, inserted into the <HEAD> of my document.
  2. Compiled all of the CSS attributes etc. into a single style region, also added to the <HEAD> of my document
  3. Created another Javascript area at the very bottom of my document right before the </BODY> tag to call the relevant functions and begin syntax highlighting.

    The result is, as can be seen below, some beautifully highlighted code. Thanks to Alex Gorbatchev for his wonderful work.

Vista Media Center Two Cents

December 23, 2007 Posted by Jason Irwin , 1 comment

I mentioned in a previous (less happy) post that I had switched to media center having formerly used media portal. Frankly, I hadn't used my PC as a media center in quite some time, so when I purchased a new PC and got a copy of Vista Ultimate x64, I decided to brush off my old dual tuner and give Vista Media Center a test drive. I only have basic cable as I tend to watch TV series and movies in bulk a la Netflix, but for newer series, sports events, etc., I've gotten into a routine of recording it using media center, removing the commercials and watching it on my 19 inch monitor.

Media center is a beautifully polished application that has become part of my daily life. Its search features are awesome and everything just feels like a real DVR - not an application running on a Windows box. Personally, I would have liked a fully fledged Picture-in-Picture mode, otherwise very little is missing from the setup. I do not own, nor have I ever owned, a TiVo, so I can't compare the two…however, I am so happy with MCE that I don't feel the need to change.

Fortunately, Media Center also has quite a large community backing, with users creating all sorts of plug-ins - from Netflix and eBay browsers, to actual applications that extend the capability of media center. With this in mind, below are the Media Center plug-ins that I just couldn't live without:

ShowAnalyzer/Comskip ( and respectively)

The chances are that if you've used any dvr software on a Windows box you've run across Showanalyzer and Comskip. They aim to do the same thing, and are both (in my experience) quite effective in doing it - they scan recorded TV shows for commercials, outputting commercial information to a text file which can be read by other applications. Due to advertising revenue, TV stations seem a little reluctant to embrace commercial skipping - and to the best of my knowledge TiVo does not offer any automatic commercial skipping .

Comskip may be the publics favorite, since it is the free to use. I've found the out-of-the-box results to be pretty good on most stations and the wealth of configuration options will drive any technically-able user mad with excitement. Configuration is all done via a text file and the application itself is command based. Comskip is accompanied by Comclean and DVRCut which allow the detected commercials to be permanently removed.

ShowAnalyzer on the other hand is (at the time of writing) $20, though I personally purchased it a few days before the price was hiked from $10. It does the same thing as Comskip and again the results were pretty good out of the box. Showanalyzer supports the real-time detection of commercials and is packed with an application called SchoolHouse which is used to tune your commercial skipping settings. There is also a small configuration application which I prefer to Comskip's config file approach. ShowAnalyzer has its own UI, compared to Comskip's dos based approach - though I'd like to be able to select multiple files to scan from the UI (right now only single file selection is supported).

DVRMSToolbox (

DVRMSToolbox is the most complete set of tools available for dealing with Microsoft's DVR-MS filetype. It interacts with Comskip or Showanalyzer - enabling the detection and/or removal of commercials, and more pre and post-processing options than you can imagine - including conversion to mpeg, wmv etc. It has a file-watching service which allows the monitoring of a specific directory whose contents will be scanned when a new file is added. DVRMSToolbox's true beauty lies in the myriad of configuration options and the ability to create profiles to perform almost any sequence of tasks that you could possibly imagine on a recorded file. Another free application, DVRMSToolbox is the ultimate package for anyone interested in interacting with their recorded media.

Lifextender (

Lifextender is a beautiful little application which, similarly to DVRMSToolbox, uses Comskip* to detect commercials in DVR-MS files. On the surface Lifextender offers fewer configuration options than DVR-MS toolbox. Its beauty, in my humble opinion, is better support for the 10-Foot Interface with which many Media Center users are familiar. Interaction with DVRMSToolbox requires a PC setup, but if using your media center box as a dedicated PVR, remote control interaction will be much more straightforward with Lifextender. It allows the creation of rules for commercial removing based on theTv channel, the show's title etc. Furthermore, it allows scans to start automatically when Media Center stops recording.

*At the time of writing Lifextender does not support Showanalyzer. However, the developers of this application have included it in the latest beta version!

Webguide (

For me Webguide is worth it's weight in gold. Previously a licensed application, in September of 2007 Microsoft and Webguide's creator Doug Berret came to a deal with Doug joining the Media Center team while making Webguide available for free! What does this mean to the man on the street??? It means that we now have a high quality and free plug-in for media center which allows for seamless remote viewing and scheduling of media. Live or recorded TV (as well as all manner of music/pictures and even DVDs can be streamed to a browser over the internet. When on the road you can schedule TV shows to be recorded from the comfort of your laptop or even pocket pc or Smartphone.

I have used Webguide for approximately 6 months now and am completely blown away by this application - from its streaming options, to the beautiful TV guide interface, this app is a must have for any self-respecting MCE user. And its price-tag isn't too shabby either!

mceBackup (

If, like me, you are running media center and are a little concerned at the possibility of your settings/recorded shows being blown away the next time you fool around with your PC configuration, then mceBackup by Ian Dixon, is a wonderful little nugget. It allows for the scheduled backup (and if necessary the immediate restoration) of your settings, recorded tv and 'extra folder' and runs as a service with a simple but pretty graphical interface. Frankly this is an application that I don't interact with too often, but one that I rely on every day (actually, every night at 2 A.M.) to keep the state of my media center up to date. Like some of these other entries, it's free as in beer.

Tuner Issues...

December 20, 2007 Posted by Jason Irwin , , , No comments

A while back I decided to go for the whole Media Center experience, and while I didn't have a copy of Windows MCE at the time, I used and open source alternative - MediaPortal ( I bought a dual tuner - specifically a Hauppauge PVR 500 MCE, which worked a treat and allowed me to watch one show while recording another - perfect!

Lately I've bought a new PC - Quad Core, 4GB ram, dual monitors, Vista Ultimate x64...a pretty nice machine for my purposes! Similarly to most computer folks out there, I relish the painstaking labor of a fresh install - loading all my apps and my settings and configuring my new box just right. All went well and in a matter of hours I was able to run Vista's in-built media center - a beautifully designed piece of software (though PiP would have been a nice addition…). Watching tv shows wasn't an issue, and all was well…or so I thought.

Days went by before I decided to watch my first scheduled recording - but to my horror I had nothing but a few minutes of green screen. The same went for the other shows I had set up to record. So I did everything conceivable, reinstalling a bunch of drivers for my Hauppauge TV tuner. At first everything worked ok. I installed, I saw tv - happy days. But once I rebooted (regardless of the driver I installed) the green screen came back!

I ripped my configuration apart but finally came upon a post which offered a solution - necessitating a fairly large tradeoff. Apparently many users have been having this issue and the hauppauge forums are flooded with complaints by angry users such as myself. Hauppauge seem to blame Windows, specifically a memory issue - the only fix I can find is as follows:

Yes, you read that correctly:

"The only 100% guaranteed fix is to reduce the total system memory so that it is below a certain amount (i.e. < 3 GB). This can be done either by pulling RAM sticks from the machine or by using a command prompt in administrator mode with the command bcdedit /set {current} removememory X where X is the amount in MB to hide from total system RAM."

I used bcedit, removing a gigabyte of ram from my system - and MCE has worked without an issue for a few months! Meaning that I have been running on only 3 of my 4 cylinders for a few months - I am pretty annoyed. Apparently this may (read "I don't believe this for a second") be fixed in Vista SP1, but from the later user posts in the above forum, it appears that the issue continues, only this time with a black screen. I plan to test this theory as I want my memory back!

Powershell Password Tool

December 19, 2007 Posted by Jason Irwin No comments

In the dark days before Windows Authentication was so embedded in (non-microsoft) mainstream applications, Windows users had to remember a myriad of passwords for a plethora of applications. Application development has changed - but relics from previous software eras remain. On desktops all over the world lay applications that were not developed to plug into any external authorization system. Passwords must still be remembered.

At work, I have access to a decent number of passwords that, due to the intermittent nature of their use or their necessary complexity, I just cannot remember. The ideal way to store these would be in a secure repository to which only I have access. An issue remains - sometimes it is necessary to input a password when another user is present - a user with lesser privileges in the given system. The tendency is to ask the user to turn around while I sneak the password from the repository and paste it into the login form…an effective solution but not very elegant.

So I came up with a little powershell script, which allows me to select a password category (e.g. the admin password for a source control system), pulls the password from the SQL repository and outputs it to the clipboard. It took no more than 30 minutes of programming, and I have been using it effectively ever since.

Here's the breakdown:

  1. I created a simple SQL2005 repository, with one table containing the menus (for instance SQL Admin passwords, Source Control Admin Passwords etc.) and another containing a server name and the password for that server. I did not use any encryption in this example, but you can see how easy it would be to do so. Here's a simple DB diagram:

  2. I downloaded and installed PowerSMO (, allowing my powershell script to talk to the SQL database that I just created.
  3. I created the below script to pull the password in question from the database and piped it to the clip command - an inbuilt vista executable which allows the programmatic passing of objects to the windows clipboard.

    Note: the clip executable is located in the System32 directory in Windows Server 2003/Windows Vista. While I cannot attest to the legality of (and therefore cannot recommend) copying clip.exe from your copy of Vista into the same folder on your Windows XP box, the clip.exe functionality can be mimicked on an XP box by doing so. Technically speaking, this script should work on an XP box also.

  4. Actually, there is no 4. Now when I'm in an awkward situation, I crack open powershell and pass my password to the clipboard! It's as simple as that. Please feel free to test this script out and let me know how it works!

Free Visual Studio 2008 Training???

December 17, 2007 Posted by Jason Irwin , , No comments
A colleague of mine sent me a link for some free Visual Studio 2008 Training. Neither he nor I have ever used innerworkings content, nor do we have any affiliation or experience with the organization, so i can in no way endorse this software. However, if you are adventurous like me, and are interested in learning a little more about 2008, this may be interesting.

The promotion is split into 3 optional components:

* New Features in C# 3.0 (1 hour)
* New Features in VB 9.0 (1 hour)
* LINQ to SQL (1 hour)

Once I have taken the training i will blog my opinions/comments. However, if you are interested in doing so before then (and apparently this is a limited time offer) go ahead and take a look at the link below:
