• GUI style question: Icons in context menus?

  - by Andrew White

  Hi, It seems like not so long ago that it was standard to have icons/images in context menus and Microsoft seems to keep this up. But nowadays it seems to have disappeared in other apps: Chrome, iTunes etc. Anyone have an opinion / idea why this has happened or is it just completely personal taste (I for one like the images).

• In .NET, will cleaning a nested dictionaries parent release all memory upon garbage collection?

  - by Tomer Pintel

  I have the following nested dictionaries: Dictionary<int, Dictionary<string, object>> x; Dictionary<int, SortedDictionary<long, Dictionary<string, object>>> y; If I do x.Clear() and y.Clear() will all the nested objects clear and all the memory will be reused on the next garbage collection? Or do I need to iterate on all the items and clear them manually?

• Improve SQL Server 2005 Query Performance

  - by user366810

  I have a course search engine and when I try to do a search, it takes too long to show search results. You can try to do a search here http://76.12.87.164/cpd/testperformance.cfm At that page you can also see the database tables and indexes, if any. I'm not using Stored Procedures - the queries are inline using Coldfusion. I think I need to create some indexes but I'm not sure what kind (clustered, non-clustered) and on what columns. Thanks

• What is the correct terminology to describe a visual display that is about the size of a living room

  - by JW

  I'm thinking that, as flat screens get bigger and cheaper it won't be too long before 'digital wallpaper'-like screens become popular in people's living rooms with a host of applications that could take advantage of this particular screen size/resolution. Is there a proper name for this size of screen? 'Wall Screen' - is too ambiguous 'Massive Screen' - is probably best reserved for something you'd put on the side of a sky scraper 'Small Screen' - nabbed by the mobiles 'Large Screen' - kind of means desktop I'm thinking of the kind of screen used in 'Minority Report'.

• Real-time spectrum analyzer with API

  - by bobobobo

  I'm looking for a C or C++ API that will give me real-time spectrum analysis of a waveform on Windows. I'm not entirely sure how large a sample window it should need to determine frequency content, but the smaller the better. For example, if it can work with a 0.5 second long sample and determine frequency content to the Hz, that would be wicked-awesome.

• Does variable = null set it for garbage collection

  - by manyxcxi

  Help me settle a dispute with a coworker: Does setting a variable or collection to null in Java aid in garbage collection and reducing memory usage? If I have a long running program and each function may be iteratively called (potentially thousands of times): Does setting all the variables in it to null before returning a value to the parent function help reduce heap size/memory usage?

• Receive Event Notification Broad-casted from Fortran in Managed Code

  I have a fortran (unmanaged code) dll as the calculation engine, and a C# form as the GUI. Now, the calculation in fortran is long, so in order not to bore the users, I decided to use Asynch command to create a progress bar. The fortran dll would be responsible for putting messages in the progress bar as the calculation proceeds. Any idea how this can be done?

  - by Koert

  We're using Hudson on an SVN repository that hosts a number of projects. One of these projects takes a long time to build, even if no files were changed. Right now Hudson's "Poll SVN" detects that the subversion repository has changed and will try to build the project, even if that change was in a different project. Is there a way to set up "Poll SCM" to only respond to changes in a certain branch?
