Context aware SharePoint custom action in a form library

Question

I'm trying to create a custom view for creating reports based on InfoPath form items which have been submitted to a SharePoint Form Library.

I want to

1. expose a checkbox next to each list item in a list view
2. create a custom action in the Actions menu titled "Create Report"
3. when the action button is clicked, run code which is aware of the checked boxes

I am sure there is good documentation on how to create a custom action.

But how would you expose a checkbox alongside list items in a view?
And how can you determine which items were checked when running the custom action code?

The functionality in the form library "Relink Documents" view is similar to what I would like to accomplish.

A blog post "Select Multiple List Items in SharePoint Feature" covers exactly what you want and shows step-by-step instructions including code to have a checbox column and a custom action that zips selected items and downloads them.
