  - by Kotti

  Hi, Does anyone know good and simple to use in production code R-tree (actually, any implementations - R*, R+ or PR-tree would be great)? It doesn't matter if it is a template or library implementation, but some implementations that google found look very disappointing... Thanks in advance.

• Can you transport a Javascript object to server and receive it in the same state?

  - by zorglub76

  I'm considering creating a simple remote debugging application for Javascript. Actually, I want to provide an object to Firebug Lite and let it do all the job. So, can I get an object from one page, serialize it, send it to server and then to another browser and finally see the same results in Firebug Lite (on that other client) as I would see on the first browser (with doing "console.dir(obj)")? Is it possible to do?

• Capture bitmap of window in isolation (Windows OS)?

  - by Jake Petroules

  I know there's a way to capture a bitmap of a window in Windows without anything that may be obscuring it (e.g. you have a window with a dialog in front, but the dialog is not captured as it would be if you did a simple pixel grab), but I can't remember how to do so. Also I believe this is only possible in Windows Vista and above, with the introduction of the compositing window manager?

• Detecting if MSBuild/.net 4 is installed from C# code running on 3.5?

  - by Michael Stum

  I have an application that is running on .net 3.5 SP1 and that is supposed to check if .net 4 is installed. Actually, I'm more interested if MSBuild v4 is installed, which would boil down to a simple File.Exists(@"C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe"); However, apart from the fragility of the 4.0.30319 Version (and the Windir, but that's easy to solve), I wonder if there is a more appropriate way, like an API?
