I want the user to be able to put the cell into editing mode and highlight the row the cell is contained in with a single click. By default, this is double click. How do I override or implement this?

I have experience programming dynamic websites using both php and perl driven CGI code, (both on apache web server on *nix systems, though that shouldn't matter). I do not have too much exposure to other technologies for web creation, but I frequently hear hailing and railing towards them from all forms of developers. (The most I've he...
The possible values of PixelOffsetMode are: Invalid Default HighSpeed HighQuality None Half I'm guessing that HighQuality = Half, HighSpeed = None and Default = HighSpeed.

However, everything I've learned about thread-safety screams "bad idea!" ...
We have built a Windows Service that is running on client's machines, which occasionally downloads a newer version of itself, and then performs a self-update: installs a new service, starts it, stops the old one, and eventually deletes it. The service cannot stop itself directly and do other stuff, so it spins another executable, which d...
