Using classes for workflow association data

Tue, 16 Jun 2009 22:23:02 GMT

I am using workflow with association form in one of my current SharePoint projects. When workflow is added to list there are some parameters that user must insert. Workflow instances are able to persist association data and to be more flexible the association data is saved as XML string. But in the code it is more convenient to use object instead of XML strings. I will show you how I solved the situation.

An ICommand with IsEnabled

Thu, 26 Mar 2009 01:54:38 GMT

ICommand is a simple interface with three members - Execute, CanExecute, and CanExecuteChanged. You can write your own implementations of that interface, one for each command, but that gets a bit heavyweight. So there are several implementations of ICommand that are pluggable and re-usable, like DelegateCommand, RelayCommand, and RoutedCommand. This demonstrates another approach.

Windows Workflow a total rewrite in Dot Net 4.0?

Wed, 18 Feb 2009 10:40:24 GMT

I read the latest Visual Studio Magazine Editor's Note with some interest. I agree with a lot of what Patrick says in his piece. Microsoft is seriously damaging the Dot Net developer community and adoption in the industry with these half baked product releases and abrupt about-faces after shipping. As I wrote in another blog, I have seen the adoption problems myself. People outside the developer community are starting to view Dot Net as an unstable platform to build on, and that hurts all of us who make our living on the Dot Net Framework.
