We return briefly to the ongoing Chinese/English dictionary series and write some code to display all the definitions we had worked so hard to collect. (I figure you're anxious to see something on the screen, so I am going to handle the Traditional Chinese/Simplified Chinese issue later. For now, the "Simplified" column will be blank.) ...

Why does Explorer eject the CD after you finish burning it?

Raymond Chen
Partly as a convenience, but partly to work around buggy hardware. The developer responsible for CD burning explained it to me. Most CD drives cache information about the disc in their internal memory to improve performance. However, some drives have a bug where they fail to update the cache after the CD has been written to. As a result, you ...

Why can't the default drag/drop behavior be changed?

In the last 10 years, he's been quoted at least a dozen times by the New York Post. He's been quoted at least 14 times by the Daily News, most recently just ...

As many people quickly figured out, the reason why the the returns immediately is that the call is failing. The reason is that the second process opened the handle with access, which grants permission to call the function, the function, and the fatally flawed function, but it doesn't include access, which is necessary if you ...

A quick puzzle about security and synchronization

June 6, 2005 Jun 6, 2005 06/6/05
Raymond Chen
This quick puzzle floated past one of our internal discussion groups. In Process B, the succeeds, but the returns immediately instead of waiting. Explain. [Correction: I confused the matter by passing as the third parameter, thereby creating an event that is initially signalled. Change it to so that the event is created non-...
