Using Protocol Transition and Constrained delegation in a K2 Workflow

2008-10-24T12:40:00Z

Today we are going to look at a very advanced topic, namely how to use protocol transition with constrained delegation in a K2 process. Wow, that was a mouth full already, so let's break it down and make it as simple as possible before I lose you all in the opening paragraph. The questions from that first sentence are: What is protocol transition and why should I care? What is constrained delegation? Why would I want to use all of this in a K2 process? This sounds so complicated - can it bring about...(read more)

Sending emails to Destination user

File this one under miscellaneous tips, it might come in handy for someone somewhere. The symptoms You want to send an email to the destination user using a standard email event wizard, but the check box for send to destination user remains grayed out and you don't understand why. You use the API in the code behind a server event, client event or in a destination rule or anything and try the following fairly innocent looking code: Console.WriteLine(K2.ActivityInstanceDestination.User.Email.ToString());...(read more)

Logging Framework - Log to a SQL Table

2008-04-16T11:14:00Z

I'm sure many of you have heard about the K2 [blackpearl] Logging framework by now or have seen Matt's post on how to create a custom logging event . So today we're going to look at one of the options in the logging framework to log directly to a DB table. This has the advantage that you can quite easily filter and report on the results, and can make it much easier to reach the results in a distributed or secured environment. What I mean by this is that text log files dropped into a folder on your...(read more)

Intro post

Hi there underground!

Before we get this blog going I guess it would be good to start with a short intro post. As the name of the blog suggest I'll try to introduce you to some advanced K2 concepts (handing a knockout blow to that custom event template), but at the same time I will also try to share any random tips that I do come about. Hopefully this will be useful to someone out there, and probably good for me to help remind myself some of the things I come across over time.

My name is Gerhard and I've been working with/for K2 since the early betas of K2.net 2003 way back in yonder year of 2003 and over the years I have consulted in various capacities on K2 projects on 5 continents all over the world in all kinds of industries from major global projects to small little intra-department processes. My favorite feature of K2 is the fact that you can expand on the platform by going into code for almost anything, allowing you to customize a process to whatever your coding skills can let you. I also love the fact that we are always playing with cutting edge tools and working on the tip of the technology wave most of the time. This obviously has some frustrations attached to it as glitches are sorted out with new tech, but that is part of the game, if you don’t want to get hurt then go knit a jersey or something.

Ok that's enough intro stuff for now. Next time I'll write something techy for you I promise. Some posts I have in mind is to talk about exception handling in K2 BlackPearl, SOA architecture thinga majings, and maybe I'll tell you how a K2 process can achieve world peace (but that's only for extremely advanced users so remember to practice your Kata)....
