A White Halloween?
This is not the weather map I expect to be looking at in October in Maryland:
If we get any appreciable amount of ice and/or snow, a lot of trees and branches are going to come down, since most of the leaves are still up.

We enjoyed bringing you "That Podcast" - and soon, we'll be doing another podcast: Thu'umcast: A Skyrim Gameplay Diary. We'll have an iTunes feed, and a Facebook group, probably a Google + setup as well. Stay tuned - once the game launches, we'll start recording!

Today we'll look at setting (and unsetting) an error handler for database exceptions. In some cases, you may not want to catch all possible errors at the place they originate; you'll want a catchall handler specific to database issues. That turns out to be easy to set up in VA Smalltalk:
"set up an error handler for db work" AbtDbmSystem activeDatabaseMgr errorBlock: [:error | Transcript show: 'Whoops, that did not work out for us: ', error errorText printString; cr].
To illustrate, let's execute a query that won't work:
"try a query that should throw an error" resultCollection := OrderedCollection new. querySpec := (AbtQuerySpec new) statement: 'SELECT EMAIL FROM PEOPLE'. result := connection resultTableFromQuerySpec: querySpec. result do: [:eachRow | resultCollection add: (eachRow)]. ^resultCollection.
Instead of an error notifier, you get a message in the Transcript:
This can be useful when you are running a server system, and don't want a default notifier to pop up. Instead, you can log the error, and then have the system do something intelligent - quit, reset connections, whatever. If you want to reset to the default handling (for development, probably), just execute the same code with a nil argument:
"reset to default handling" AbtDbmSystem activeDatabaseMgr errorBlock: nil.
Now you'll see the default handling when you try that bad query:

The website design is up - it's waiting for the launch of the game. We also have a Facebook group ready to go. If you liked "That Podcast", you'll probably like "Thu'umcast" :)

Today we'll look at checking the results from a query in VA Smalltalk, and then prompting the user on empty results. Let's do a query that should result in no answers:
"try a query that should return no rows" resultCollection := OrderedCollection new. querySpec := (AbtQuerySpec new) statement: 'SELECT * FROM PEOPLE where ZIPCODE = 34567'. result := connection resultTableFromQuerySpec: querySpec. result do: [:eachRow | resultCollection add: (eachRow)]. resultCollection isEmpty ifTrue: [CwMessagePrompter message: 'No Rows Came Back' title: 'No Rows'].
The checking is fairly obvious; we simply use standard collection protocol. Then we use the standard CWMessagePrompter class to pop up a warning dialog.
And that's about it for today

I see that there's a lot of wailing and gnashing of teeth about the requirements Apple has announced for apps that come from the App store. Unless they start requiring that apps use the App store, this actually puts in place an interesting two tier system:
I think we need to see how Apple lets this play out before anyone panics. I also think there's a fairly large market for people who want to treat their computer like an appliance that doesn't need ongoing maintenance....
