Nice Work Kerry

Indeed, very nice.  I really like the idea of breaking the steps down into something easy to follow :)
Can't claim credit for it Bobby, in principle that's straight out of the AutoCAD Docs  .. one of the PowerPoint presentations if I recall.

How was AU for you this year ? Hope you had a good attendance .

Just reading one of your AU2004 Handouts Bobby<CP24-2> .. see that you do  'like the idea of breaking the steps down ..' :-)

Ack!  I remember that one :-)  I didn't get good vibes from it.

However, it went *much* better this year.  And it had a lot more code examples.  I'll see if I can get them up on the board this week if anyone is interested.

Playing with the next step .. adding multiple Entities to the Database in one Transaction

Any Comments ?

The Tester :
Code: [Select]

using KdubTest.Util;
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.Colors;

// NOTE: LoaderLock exception break toggled OFF to suit vs2005 in AC2006. kwb

Kerry,

From my quick look, nicely done. The only thing I would add would be to check the validity of the incoming ents array.
if null or length == 0, return null immediately.

Other than that, which is just personal, it looks solid.

Cheers,
Glenn.

Hi Glenn

I have a note on my version to test for null

I did have a test for if ents.length == 0 return null; which worked fine, but still needed to test each array item for null, 'cause it spat the dummy if any of the items were null when I tested it.

I think the code is about as tight as it will ever get.
