Pass XRM Ribbon Parameters Using JavaScript Array

Trying to pass the list of selected items from a grid using query parameters has limitations due to restrictions on the size of a URL.  Instead use JavaScript to pass Ribbon parameters to a variable on the XRM page and grab the data in the popup window.

Ribbon Command Setup
Here we pass the SelectedControlSelectedItemIds which will pass an object array of all the record ids that are selected on the home grid.

Ribbon JavaScript Web Resource
The web resource will data the ids and post them to a new variable in the main XRM window then opens a popup window.

AddApplicantsToCourse.htm
This popup page will get the ids from the page that opened it.  In order to do so we need to do the following:

-Include jQuery
-declare the array to hold the id values
-copy the values from the object in the parent page to the array you created

Windows Server 2008R2 VMs Shut Down After 1 to 2 Hours

Image
When created a lab environment to test ADFS 2.0 I utilized the Windows 2008R2 VM baselines distributed by Microsoft.  After a few days I was told that I had to activate.  The VMs included a 180 day license for use but I didn't feel like adding another network adapter into Hyper-V to connect them to the internet.  I started having issues though where the servers would shut down every hour or so.  I though that maybe there was a memory issue and Hyper-V was shutting them down in order to free up RAM.  Turns out that if Server 2008R2 is not activated it automatically shuts down after a period of time.  After connecting the server to the internet and activating them the problem went away. Finally the madness of the unknown shut downs has ended :)
