How do i attach a scrollbar to a container?

Question

Hi i use
docc.verticalScrollPolicy=ScrollPolicy.AUTO;
so scrolling works but i want to attach a scrollbar. Here is my bulky code. I have no idea how to get a scrollbar attached to this. I now my scripting is pure chaos...

Thanks, but I had figured this out.  Let us suppose you are replying to an email from the boss who, copying 50 Polish, Indian, Arab and Thai coworkers on their personal emails-- and with whom you have never previously communicated--has asked you to share with the group your latest drafts for the upcoming weekend top secret strategy session and now you want to attach something other than a photo, such as a slide presentation in ersatz PowerPoint, a draft marketing plan in fake word and the budget in pseudo excel? You are fly fishing in the pesos without access to a computer, only your trusty IPad which fortunately has the drafts you need and a wireless connection.  Because this new initiative must fly under the company radar screen due to its sensitivity, you cannot use the corporate VPN and the attach docs are too chunky to be in anything but a series of three emails as you have no compression software.
What is most efficient way to execute?  If it's to drive the two hours in the storm back to Santa Fe and use the local Kinko's, I am disappointed.
