• Automatically select option from select menu with link

  - by Ben

  Hello there, I am trying to use php (and if not php, javascript) to link to a page and include a "?type=foo" or "#foo" at the end of the link so that when the linked page loads it will automatically select a specific option, depending on the end of the link, from a dropdown menu in a form. I have tried to search for this but do not know what this action is actually called, but I've seen it done before. Does anyone know how to achieve this? Thanks very much.

• Fluent: Table name different from entity name

  - by Matt

  I am trying to use the automapping feature of Fluent with nHinbernate to map a class with a different name than the table itself is name. (This is purely for stylistic reasons we have a class named Foo which contains an object named Bar but the table name is FooBar. We would rather not have a property Foo.FooBar.) I can't find anything detailing how to give Fluent a clue on this change.

• How to move a struct into a class?

  - by Kache4

  I've got something like: typedef struct Data_s { int field1; int field2; } Data; class Foo { void useData(Data& data); } Is there a way to move the struct into the class without creating a new class? Currently, just pasting it inside the class and replacing Data with Foo::Data everywhere doesn't work.

• Inconsistent syntax c# ?

  - by maxp

  private string[] GetRoles() { string[] foo = {"Test"}; return foo; } The above compiles, but... private string[] GetRoles() { return {"Test"}; } Does not.

• "Add Controller" / "Add View" in a hybrid MVC/WebForms ASP.NET application

  - by orip

  I have an existing WebForms project to which I'm adding MVC pages. I created an MVC project and copied the project type guids. It works fine, but I can't get Visual Studio to display the "Add Controller" or "Add View" wizards on my controllers and views directories (they're not /Controllers and /Views, they're in /Foo/Controllers and /Foo/Views). Is it possible to enable the wizards?

• Is there a way to specify a default property value in Spring XML?

  - by Rog

  We are using a PropertyPlaceholderConfigurer to use java properties in our Spring configuration (details here) eg: <foo name="port"> <value>${my.server.port}</value> </foo> We would like to add an additional property, but have a distributed system where existing instances could all use a default value. Is there a way to avoid updating all of our properties files, by indicating a default value in the Spring config for when there isn't an overriding property value defined?

• Java method missing (ala Ruby) for decorating?

  - by cibercitizen1

  Is there any technique available in Java for intercepting messages (method calls) like the method_missing technique in Ruby? This would allow coding decorators and proxies very easily, like in Ruby: :Client p:Proxy im:Implementation ------- ---------- ----------------- p.foo() -------> method_missing() do_something im.foo() ------------------> do_foo p.bar() --------> method_missing() do_something_more im.bar() -------------------> do_bar (Note: Proxy only has one method: method_missing())

• How do you pass SOME_LIB="-lmylib -lmylib2" in a BUILD_COMMAND for ExternalProject_Add()?

  - by Bill Katz

  I'm trying to pass a quoted string through BUILD_COMMAND in ExternalProject_Add() and every way I try it's getting mangled. The code is this: set (mylibs "-lmylib -lmylib2") ExternalProject_Add(Foo URL http://foo BUILD_COMMAND make SOME_LIB=${mylibs} BUILD_IN_SOURCE 1 ...) I've tried using backslash quotes, double quotes, inlining the whole thing, but every time, either the whole SOME_LIB=... part gets quoted or my injected quotes get escaped. Is it not possible to get quotes through to the command line?

• Move from *this in an rvalue method?

  - by FredOverflow

  In C++0x, methods can be overloaded on whether or not the expression that denotes the object on which the method is called is an lvalue or an rvalue. If I return *this from a method called via an rvalue, do I need to explicitly move from *this or not? Foo Foo::method() && { return std::move(*this); // Is this move required or not? } Unfortunately, I can't simply test this on my compiler since g++ does not support this feature yet :(
