• How do I debug a Unity Container "Resolve"?

  - by willem

  I'm using the MS Unity container to do dependency injection, but a "Resolve" is returning unexpected results. Is there an way I can debug this resolution? It would be great if I could view what Types/Instances are registered in the container, but I can't see where this is stored when using QuickWatch. It would also be useful if I could get the container to output some debug Traces. Any suggestions?

• How to check if String value is Boolean type in Java?

  - by Ragnar

  I did a little search on this but couldn't find anything useful. The point being that if String value is either "true" or "false" the return value should be true. In every other value it should be false. I tried these: String value = "false"; System.out.println("test1: " + Boolean.parseBoolean(value)); System.out.println("test2: " + Boolean.valueOf(value)); System.out.println("test3: " + Boolean.getBoolean(value)); All functions returned false :(

• Is there a link to the "latest" jquery library on Google APIs?

  - by Nick Pierpoint

  I use the following for a jquery link in my <script> tags: http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.js Just wondered if anyone had discovered whether there's a link to the "latest" version: Something like the following (which doesn't work): http://ajax.googleapis.com/ajax/libs/jquery/latest/jquery.js (Obviously not necessarily a great plan to link your code to potentially changing libraries but useful in development)

• Is prefixing Windows Forms control names with their type OK?

  - by name

  I have seen many responses that say that prefixing variables with their type is bad, since C# is statically typed and we have Intellisense, but I find that prefixing the names of the controls is useful because I don't need to remember the name of the controls or switch to the designer frequently. For example: btnLoad // Button tbFilePath // TextBox tvFileSystem // TreeView Is this considered bad? If it is, what's the alternative?

• What restrictions exist choosing a MFC version to use with Visual C++?

  - by John

  Each version of Visual Studio comes with a specific version of the MFC framework, but I believe MFC SDK can be downloaded separately. Since MFC is just C++, is there any reason you couldn't use the latest version with an older version of VC++... I don't mean trying to get the ribbon working in MSVC++ 6, But we're on VS2005 and some of the newer MFC features would be useful.
