jQuery UI and Windows 8 and Internet Explorer 10 touch screens

I recently did a blog post describing how to enable the jQuery UI drag effects. In this post I showed how to get the draggable effect to work on an iPad. While that works just fine it isn’t the end of the story. Microsoft has shipped Windows 8 and Internet Explorer 10 and the jQuery UI draggable effect doesn’t work there as is.   The solution Fortunately the solution is a lot simpler and doesn’t require an additional plug-in. It turns out that Internet Explorer 10 has quite a good support for pointer and gesture events. What we need to … Continue reading jQuery UI and Windows 8 and Internet Explorer 10 touch screens

Side by side versioning of workflow services

One of the really important new features in Windows Workflow Foundation 4.5 is the capability to version workflows and workflow instances. You get to choose what you want to do, either keep running existing instances with their original workflow definition or upgrade them to the latest workflow definition. In the previous blog post I described how to upgrade existing workflow instances to run with the last version.

Updating workflow instances using an update map

One of the really important new features in Windows Workflow Foundation 4.5 is the capability to version workflows and workflow instances. You get to choose what you want to do, either keep running existing instances with their original workflow definition or upgrade them to the latest workflow definition.   What should you do, upgrade exiting instances or run multiple definitions side by side? Both the upgrade to latest and keep running with the original definition make sense in different scenarios. If you find a bug in your workflow definition the update scenario is probably what you are looking for. However … Continue reading Updating workflow instances using an update map
