Lots of Fun with Office Add-Ins
Today I kept busy working with another developer getting an add-in working correctly in Office 2003. She has most of the code working, but the problem was that VB .NET wasn't playing very nice with the add-in object model. For some reason, at certain times were were getting an
ExecutionEngineException, which screwed everything up. (Plus, I love the fact that the add-in model decided to name an interface
Exception, which makes for oh-so-much-fun adding a generic exception handler, but I digress.) On a whim, we thought, hey, let's try this in C#. And, lo and behold, it worked.
Well, that's not telling the whole story. There's some really odd quirkly things you have to do to call properties and methods in the add-in model correctly that don't make any sense to me. I mean, why should I have to call
InvokeMember() on a .NET object to get a collection back? Oh, well, it works now. It's an add-in that helps users at the client pick conference rooms that aren't being used at a particular time. For some reason, it's a real PITA in that there's no way to get open rooms in Outlook the way they have it set up, so this add-in makes it really easy to find open rooms. We have them grouped into a tree view control that puts the rooms into building and floor nodes. It kept me interested and occupied today, and that was a good thing. Plus, I can now say I wrote an Office add-in!  
 Actually, I didn't "write it." The other developer had done most of the work, and she just ran into some really weird technical issues. I just came in and added the pair-programming view to it. In case my manager is reading my blog tonight (which I know he does), I'M NOT SAYING THE ADD-IN IS DONE. It still needs some polish and shine!
