I know that posts have been few and far between (ok ..non-existant) this month. I hope this isn't something that will be repeated ... this month has just been crazy busy with deadlines (I'm sure you know that feeling...)

Anyway, I have a healthy backlog of topics that I want to blog about over the summer:

• Multi-threaded UDFs in Excel 2007;
• RefEdit control for COM addins written in managed code;
• C API enhancements in Excel 2007;
• PivotTable stuff
• I get lots of questions about PivotTable programming so there is plenty I want to talk about here;
• Ribbon customisation;

I'm at TechEd next week and am hoping that the flight time there will give me time to get started on some of these posts.

Feel free to drop me a line if there is something you would like covered.
