You normally can't get instance attributes given just a class, at least not without instantiating the class. You can get instance attributes given an instance, though, or class attributes given a class. See the 'inspect' module. You can't get a list of instance attributes because instances really can have anything as a... |

ASP.NET MVC: Making routes IIS6 and IIS7-friendly |
|asp.net-mvc|routing| |
I have an ASP.NET MVC-application which I want deployable on both IIS6 and IIS7 and as we all know, IIS6 needs the ".mvc"-naming in the URL.
Will this code work to make sure it works on all IIS-versions? Without having to make special adjustments in code, global.asax or config-files for the different IIS-versions.

How to get my own module handle? |
|winapi|dll| |
I'm trying to find a resource in my own module. If this module is an executable, that's trivial - `GetModuleHandle(NULL)` returns the handle of the "main" module.
My module, however, is a DLL that is loaded by another executable. So `GetModuleHandle(NULL)` will return the module handle to that executable, which is o... |
How to get my own code's module handle? |
If you use Maven to build, you can define your dependencies in the pom.xml file. They will then be automatically downloaded if necessary. |
I've done exactly this just recently - allowed run-time addition of C# scripting.
It's not hard at all, and this article:
http://www.divil.co.uk/net/articles/plugins/scripting.asp
is a very useful summary of the details. |
Yes. It's hard enough trying to deal with how different browsers will render valid HTML, never mind trying to predict what they'll do with invalid code. Same goes for search engines - enough problems in the HTML may lead to the site not being indexed properly or at all.
I guess the real answer is "it depends on what... |
Probably not if you have a non-complying site to begin with and are short on time.
However, and you won't believe me because I didn't believe others to begin with, but it is easier to make a site compliant from the start - it saves you headaches in terms of browser compatibility, CSS behaviour and even JavaScript be... |

Store the module handle away when it is given to you in DllMain and then use it later when you actually need it. A lot of frameworks (e.g., MFC) do this automatically. |
Basically, you have two problems: how to define point of injections in your generated code, and how to run python / ruby / whatev scripts from there.
Depending on how you generate the process, one possible solution would be to add a function to each possible point of injection. The function would check, whether the ... |

Try using enumerations for each object, you can switch on enums quickly and easily. |
Two things:
1. The scoping of the variables is done by the block they are declared in - in this case denoted by the presence of { }. Its not that there is a try scoping, just block scoping.
2 (and more importantly). You can't know where in the try block the exception was thrown. It may have been before your varia... |
I don't think that there is a property like you specify, but as an alternative you could register a ClassHandler for the ListBox.SelectionChanged event in your Window class:

The variables are block level and restricted to that Try or Catch block. Similar to defining a variable in an if statement. Think of this situation.

There's ANTLR, which is LL(*), there's PyParsing, which is more object friendly and is sort of like a DSL, and then there's [Parsing][1] which is like OCaml's Menhir.

I don't use VIM but Powershell's default output is Unicode. Notepad can read unicode, you could use it to see if you are getting the output you expect. |
In the specific example you've given, initialising s can't throw an exception. So you'd think that maybe its scope could be extended.
But in general, initialiser expressions can throw exceptions. It wouldn't make sense for a variable whose initialiser threw an exception (or which was declared after another variable ... |

You can also test if an object has a specific variable with:
>>> hi_obj = hi()
>>> hasattr(hi_obj, "some attribute")
|
Your example shows "instance variables", not really class variables.
Look in `hi_obj.__class__.__dict__.items()` for the class variables, along with other other class members like member functions and the containing module.
class Hi( object ):
class_var = ( 23, 'skidoo' ) # class variable

In .NET it would be pretty simple to set up a method that looks through an assembly and identifies each class's inheritance/implementation hierarchy. I'm sure you could do it in Java, too, if you research the [Java reflection API][1].
You could then create an array of `ITargetInterface`s and call a test method on e... |

No, generics in Java is purely a way to avoid casting of Object. |
bitnami stack subversion it's easy to install.
You can try to install so too xampp with portableapps.com and subversion.

No, this is not possible. Generics are not as powerful as templates. For instance, a template argument can be a user-defined type, a primitive type, or a value; but a generic template argument can only be <code>Object</code> or a subtype thereof. |
From an ISO C++ viewpoint, there are two issues:
(1) Is the object a POD? The acronym stands for Plain Old Data, and the standard enumerates what you can't have in a POD (Wikipedia has a good summary). If it's not a POD, you can't memset it.
(2) Are there members for which all-bits-zero is invalid ? On Windows an... |
