Scott Hanselman let me know he was going to be in town, and after some negotiation with the company PR department (who probably get the massive heebie-jeebies from this whole blog thing), I was able to accept his invitation to appear on his weekly podcast, HanselMinutes. We sat down for a little chat, and a few weeks later, I became Show #56. ...

Commenter Mike Petry asked via the Suggestion Box: Why can you dereference a COM interface pointer and pass it to a function with a Com interface reference. The call. The function called.

"Sure, we do that." Frame 3: Supertitle - "A project." Dilbert answers the phone. "No, we don't do that."† I've seen a lot of software projects, ...

The first time I saw the Seattle Symphony's new principal cellist Joshua Roman, it was at a subscription performance of Mahler's Seventh Symphony in June 2006, shortly after the then-22-year-old took the principal's seat from the retiring Raymond Davis. We noticed that there was a new face in the orchestra, and wondered afterwards, "Who was that ...

A customer asked the following question (paraphrased): Does the Windows XP Add/Remove Programs control panel expose a scriptable object model? We want our program to open the Add/Remove Programs control panel and uninstall the programs of our competitors. No, there is no object model for the Add and Remove Programs control panel, and it fri...

Most of the menu item functions such as allow you specify the menu item either by position or by command. Some of them use the and flags. Others separate the search algorithm into a separate flag.
