• How can you remove a criterion from criteria?

  - by ChuckM

  Hello, For instance if I do something like: Criteria c = session.createCriteria(Book.class) .add(Expression.ge("release",reDate); .add(Expression.ge("price",price); .addOrder( Order.asc("date") ) .setFirstResult(0) .setMaxResults(10); c.list(); How can I use the same criteria instance, but remove (for example) the second criterion? I'm trying to build a dynamic query in which I'd like to let the user remove a filter, without the backend having to reconstruct the criteria from scratch. Thank you

  - by Genady Sergeev

  Hello, I am writing a method that will set the properties of an object passed as a parameter. The method accepts one parameter of type interface and the return type of the method is the same interface. I was wondering if there is some kind of a naming convention for such methods. I was thinking of something like: FillInInterfaceTypeData or InitInterfaceTypeData but both sound clumsy to me. How do you think?

• DNS resolve without depending on router for asterisk system

  - by john

  Hello, Basically I have a Debian box running asterisk assigned an IP via DHCP with host-name XXX. My windows browser can resolve the host-name but if I use host-name in X-Lite or my SPA922 phone it fails to resolve. Is there any way of getting this to work without depending on the router or assigning a static IP (request is to make it portable). I was thinking zero-conf but am unsure (box has limited HDD too). Any help is most appreciated.

• Getting the Assembly Qualified Name of a class in Visual Studio

  - by Alex Marshall

  Hello, I'm writing a customized reflective library for some specialized custom domain logic, and that library is going to use XML configuration files that will dynamically resolve System.Type objects at runtime. However, when writing the XML configuration files, it's a bit of a pain to write the types because they need to be fully qualified assembly names for Type.GetType() to resolve them. Is there a way to find out the AssemblyQualifiedName of an object in Visual Studio without resorting to writing a program to print them out to a file or standard out or anything like that ?
