I’m on my way back from SAS® Global Forum 2016 (#SASGF), where I heard all about the all new SAS Viya™ platform, and the next exciting thing on my agenda is attending Chris Hemedinger’s course Developing Custom Tasks for SAS Enterprise Guide in Sydney on 3-4 May (it’s also on in Melbourne on 5-6 May).
If you’re interested in extending SAS Enterprise Guide to create useful tools for SAS EG users in your organization then you won’t want to miss the opportunity to attend this course. It is written and delivered by the guy that literally wrote the book on SAS EG custom tasks after all!
I first read Chris’ book Custom Tasks for SAS® Enterprise Guide® Using Microsoft .NET back in 2013 and wrote a blog post about it and how I found it useful in building a couple of custom tasks to query metadata: a Metadata Table Finder and Metadata Column Finder. Incidentally Metacoda provides these customs tasks for free if you want to use them with your SAS platform installation.
I’m looking forward to this course to find about more about creating custom tasks, fill in a few blanks, and generally pick Chris’ brains for a couple of days! :)
If you want to find out more about the course, or reserve a place, then I’d suggest you contact SAS Education soon via the contacts details on the course page.
Hope you see you there!
Yesterday I saw a question on the SAS® Communities site from Nick about Registering Custom Tasks and managing the capability metadata that’s used for role based access control on those custom tasks. I found Nick’s question especially interesting because we have some free Metacoda Custom Tasks and those techniques can also be used to control access to them.
Nick had mentioned how he used SAS® Enterprise Guide® to register the capability metadata for some custom tasks, was asking about doing the same for the SAS Add-In for Microsoft Office, and also about how one would go about removing the capability metadata. Chris Hemedinger later replied with a response that I found very useful. There was a link to one of his prior blog posts on the topic (Controlling access to custom tasks in SAS Enterprise Guide – The SAS Dummy) and some information on using RegAddin.exe to get the capability metadata populated for use by the Add-In. Chris also mentioned there was not a way to remove the custom task capability metadata short of the potentially dangerous technique of using the SAS Open Metadata Interface’s DeleteMetadata facility.
Having already registered the custom task metadata myself, I now needed a way to remove it so I could repeat the process for future documentation and testing purposes. I used the DeleteMetadata method. This is the main topic for this blog post and it serves 2 purposes: the first is that I wanted to document how I did it so I could do it again later; the second is that it was an opportunity for me to use the SAS Management Console XML Metadata Interface and capture a few screenshots along the way. I rarely use the SAS Management Console XML Metadata Interface and it’s always a journey of re-discovery every time I do. This time I wanted a permanent memory of the steps so I could refer to them again in future. I also ran into an interesting unknown-public-type issue that initially prevented me from deleting the capability metadata, so I’ll show how I resolved that too.

Chris Hemedinger’s new book Custom Tasks for SAS® Enterprise Guide® Using Microsoft .NET was recently released. If you have an idea for a really useful additional task you’d like to build for SAS Enterprise Guide, I strongly encourage you to read this book and find out how. I certainly got alot out of reading it and learning from Chris’ knowledge and experience.
I think I first spotted this book title about a year ago on SAS Publishing’s Upcoming Titles page. Since then I had been eagerly anticipating its release, so when it became available I was very keen to read it. I even got to provide a review for it too. You can read my review, along with several others, on the book’s reviews page.
One of the things I mentioned in my review was my desire to write a custom task to query SAS metadata from within SAS Enterprise Guide. After finishing the book, going through it a second time to pick up the bits I missed first time around :) , I then busily set about my .. hmm .. well .. ‘task’ …
…. and then sometime later I had a working ‘Metadata Column Finder‘ task. Here’s a screenshot of it in action: Continue reading “Reading ‘Custom Tasks for SAS Enterprise Guide Using Microsoft .NET’”
