Maybe one of the toughest things in software development to get right all the time: source control. Well now with this nice bright A3 poster printed on your wall (or maybe above the monitor of the guy who breaks the builds daily) you’ll never go wrong again.

It covers 17 proven practises broken into 5 key areas:

Things YOU should do

• Keep up to date
• Be light and quick with checkouts
• Don’t check in unneeded binaries
• Working folders should be disposable
• Use undo/revert sparingly

Branching

• Plan your branching
• Own the merge
• Look after branches

Management

• Useful & meaningful check in messages
• Don’t use the audit trial for blame

Repository

• Don’t break the build
• Separate your repo
• Don’t forget to shelve
• Use labels

Technology

• Try concurrent access
• Don’t be afraid of branching concepts
• Automerge for checkout only

Above is a screen shot of an A3 cheat sheet I created for ADO.NET Data Services (version 1). The poster covers the filters, methods and gives plenty of examples in a nice bright poster.

I created this poster (A3 in size) which covers the 8 key areas of Outlook

• Email
• Contacts
• Outlook Web Access
• SharePoint Integration
• Calendar
• Tasks
• Misc Outlook Features, like out of office assistant and inline preview
• RSS

The poster also has three areas where you can write key information that will be specific for your organisation like mailbox size limit, SharePoint & OWA URL’s.

Gallery2 is a web based PHP gallery system with a remote API for doing many things. I have been using it for a while, but have decided to change and so I wanted to export my images, which is harder than it sounds. To actually get this done I ended up writing a basic wrapper for the Gallery2 remote API and implementing a small console application to do the export.

If you are interested in the wrapper or the tool itself, I have setup a CodePlex project for it where you can download those: http://gallery2.codeplex.com/

The reason it is there, is because I have decided to open source it because it is useful to people besides me and I have gotten what I need from it, so I doubt I’ll spend much time getting it feature complete. This way someone else can get the tool (if that is all they need) or get the source and add to it.

I’ve been presenting up a storm recently: mostly because I have been on a presentation skills course ;) where I learnt a lot of the soft skills about how to be a better presenter. For that course I had to present with slides on something I knew about, so I choose LINQ. You can watch me do my presentation (it’s a mere 7min) or grab a copy of the slides.

After all that was done I have been presenting on the joys of jQuery recently, and rather than actually bore the audience with slides and constant switching to demos I decided to build a presentation system in jQuery which did both the slides and demos. Which you can view below. A few notes on it, to move to the next slide you need to click the globes at the top or press = and pressing - will make you move back a slide. You can also press the print button in the top section to give you a single page print view (i.e. stripped of colours & with my slide notes). What is great is that the entire thing is a single html page and about 100 lines of JavaScript for the slideshow system. Click the thumb nail below to view it:

Over the past week I have been learning about the complexity of working with Excel 2007 native file format - XLSX or as it is known correctly, SpreadsheetXL. There is three ways to work with it, firstly build your own parser - just too much work for me or second use OpenXML SDK format which Microsoft provides. The current version, at time of writing that was version 1, of the SDK is not great: there is very little (if any) benefit of using it over the third method. There is a V2 SDK currently in beta which looks brilliant and frankly when released would be the recommend route.

The third way, which is the way I chose is the uses new features introduced in the .NET Framework 3.0.

What is a XLSX file? A XLSX file is actually just a ZIP file which contains a number of XML files in it.

This means all you need to do is open the XLSX file as a ZIP file, get the right XML files (or parts as they are referred to) out of it and parse those.

If you are thinking this is a .NET only solutionthe chart below is from Doug Mahugh which shows a number of ways across a number of technologies/OS’s to do the same thing. This series will focus on the .NET way.

What is nice about using System.IO.Packaging to read the file over the direct ZIP options, is that there are some helper methods to make it easier when working with any of the new formats (docx, xlsx etc...)

If you are attending Dev4Devs on Saturday (or are here after the event) and you are looking for a copy of the slides and code you can get them below! If are looking for the ADO.NET Data Services cheat sheet I mentioned then you need to go here.

Code

The code here is also different from what I presented in the following ways:

• There is a timer control in it - so if you add items to the DB while on the site, it updates and shows those changes within 5 seconds.
• The layout is slightly bigger (bigger header) and has buttons (to make it look like an email client) - these were removed because it doesn’t work at 1024x768 (aka the projector resolution). So they back in their graphical beauty.
• There is a feed button which links to a ATOM feed for the last 10 emails - something I mentioned you could do, well now you can see it.
• There is a database creation script, but no data. You need to create your own data.

Slide Show

One of the things that I do at BB&D, is produce guidance posters. So far I have produced two of them and both are publically available on the BB&D developer guidance site DRP. The first is “Outlook + Exchange = Better Together” and the second is “ADO.NET Data Services Cheat Sheet”, not two things you think about together often.

Outlook + Exchange = Better Together

The title is a bit marketing-ly, but the poster is really a nice over view of the 8 key areas of Outlook namely

• Email
• Contacts
• Outlook Web Access
• SharePoint
• Calendars
• Tasks
• Outlook Features
• RSS

The poster looks a little busy, but when printed at A3 it’s not bad at all. It also includes three areas (OWA, Mailbox size, SharePoint) where you can write in your organization details so if you print them out and put them on the wall they have some organization context.

ADO.NET Data Services Cheat Sheet

The next one I developed when learning with ADO.NET Data Services and it’s a bright and fun cheat sheet for it. It includes information on the query operators (with samples along the border), a list of functions, a list of comparison operators (like less than), query order, keys, and $value. I’ve found it very useful to print out and put up. It is designed for A3, but I have it printed at A4 (in grey scale) and it works just as well.

On May the 23rd InformationWorker and Inobits are getting together and offering FREE SharePoint developer training. It is a full day event where Inobits will be providing a number of lab based training sessions focused on developing with SharePoint. Also being a full day event there will be some lunch provided for everyone (special thanks to 3Fifteen for sponsoring it). It should be a really great event for everyone, because you pick the lab/s you want to do which means if you are a beginner or expert you do the ones that will benefit you.

Because of all the effort to prep for this, you much register for it at http://www.informationworker.co.za/Pages/SLABSRegistration.aspx 

A sampling of labs available is:

• Web Parts
• Data Lists
• Event Handlers
• Workflow
• Silverlight
• Page Navigation
• Page Branding
• Web Services
• Content Types
• User Management

The stats are based off of IIS log parsing as well as off of the stats information from SharePoint (which powers it).

Previous Stats:

• March 2009
• February 2009
• January 2009
• December 2008

Some notes on it:

• Compared to last month fairly flat - but that reflects the group this month. Not much has happened.
• The Publications page remained at the top of pages, and despite other usage numbers going down - it went up. The content is a big draw card.
• Distinct Users means people which can be identified through logs/tracking to be unique (it’s not an exacting science so there may be people who are counted more than once while others are grouped together as they come from behind a proxy). They are not members and can include things like search bots. I don’t care about the number too much on this but rather the trend.
• Registered Members are people who have completed the registration form on the website.
• New members climbed by 6 which is on par with the last 5 months or so.
