September 2011 Entries

At last, I can announce that ‘BizTalk Server 2010 Unleashed’ has been published and is available through major booksellers in both printed and electronic form. The book is not a new edition of the old ‘BizTalk Server 2004 Unleashed’ book from several years ago, although Brian Loesgen, our fearless team leader, provided continuity with that title. Instead, this is entirely new content written by a team of six authors, including myself. BizTalk Server is such a huge subject. It proved a challenge to ......

One benefit of my recent experience on a BA flight was that I got plenty of time to read through “Microsoft BizTalk 2010 Line of Business Systems Integration”. I’d promised the publisher weeks ago that I would take a look and publish some comments, but August has been such a busy month for me, and they have had to be patient. I should point out that, for the sake of transparency, that with another BizTalk book about to be released (next week) which I helped co-author, I have an urgent and obvious ......

I'm sitting is a nice new hotel in Redmond - the Hotel Sierra is well worth considering if you are staying in the area. I'm sleep-deprived and jet-lagged, and it's raining hard outside, but hey, I just got to play with one of the Samsung tablets they handed out at Build, and was not disappointed. Microsoft is doing something trully remarkable with Win8 Metro. On the other hand, I am deeply disappointed with the UK flag carrier, British Airways. Indeed, I've lost patience with them big-time. So forgive ......

I've just installed the Windows 8 Developer Preview. These are some first impressions: Installation of the preview was quite smooth and didn't take too long. It took a few minutes to extract the files onto a virtual image, but feature installation then seemed to happen almost instantaneously (according to the feedback on the screen). The installation routine then went into a preparation cycle that took two or three minutes. Then the virtual machine rebooted and after a couple of minutes more preparation, ......

Following the previous post, here is a second bit of wisdom. In the Load method of a custom pipeline component, only assign values retrieved from the property bag to your custom properties if the retrieved value is not null. Do not assign any value to a custom property if the retrieved value is null. This is important because of the way in which pipeline property values are loaded at run time. If you assign one or more property values via the Admin Console (e.g., on a pipeline in a Receive Location), ......

Here is a small snippet of BizTalk Server wisdom which I will post for posterity. Say you are creating a custom pipeline component with custom properties. You create private fields and a public properties and write all the code to load and save corresponding property bag values from and too your properties. At some point, when you deploy the BizTalk application and test it, you get an exception from within your pipeline stating, unhelpfully, that "Value does not fall within the expected range." Or ......
