In another question, someone explained how to get the method signatures for the DShellFolderViewEvents methods that are enumerated in the type library. I was wondering how to find out the signatures for other events that aren't included, namely DISPID_VIEWMODECHANGED and DISPID_CONTENTSCHANGED. Does anyone know how to figure out what they could be? Thanks for any help!

Sorry this is probably a question that has been asked many times but as it regards what is a very common word in English it is pretty much impossible to google or search for it.
I have seen a few examples of Ruby code which looks like this:
EnquiryNotification.with(post: #post)
I'm trying to understand what the ".with" part does. Can anyone shed some light on this please?
with is a class method defined on the EnquiryNotification class (or one of its ancestors). The method is neither a keyword in the Ruby language nor is it a common method on classes shipped with Ruby itself or its standard library. As such, to find what this method does, you would likely have to consult the documentation of your chosen framework or application.
An example of a with method defined in a framework is Sequel::Dataset#with to add a CTE to the current query. The method is also available as a class method in Sequel model classes.
It could also be part of ActionMailer as mentioned by Stefan in a comment above.
In any case though, make sure to consult the documentation of your chosen framework or library for details.
What is the default advice kind when using <aop:advisor>? Is it around or something else? I did not find much information in docs. Any link to more information? Thanks.
Well, as the documentation says here:
The advice itself is represented by a bean, and must implement one of the advice interfaces described in Advice types in Spring.
Thus, it is your own choice which type of advice you want to implement in your advisor. It can be any of
around,
before,
after returning,
throws,
introduction.
I'm writing a function that iterates over the methods on a given struct and binds the methods to handlers. I would like to skip over internal methods if possible. I'm not sure if this is possible to do so explicitly - I reviewed the documentation for the reflect package and I didn't see a means to detect if a given Value is an internal method. I know I can get the method's name, and then check if it starts with a lowercase character but I'm not sure if there's a kosher way to accomplish this. It's also possible that the internal / public boundary really only exists at compile time anyways, so there really isn't even a way of knowing this beyond the method's name. In either case I'd like to know for sure. Thanks!
The reflect package will not give you unexported methods via Type.Method. Pretty much, if you can see it via reflect, it is already exported.

Anyone know how to get the sender class/module in ruby?
caller[0] is helpful to derive the filename and linenumber sending.
But knowing the class would be helpful. Can't find it any searches?
This would be impossible. You shouldn't be specialising your behaviour in a method based on the calling class anyway.
Think about it this way - the caller could be an anonymous function (proc) created in one class, then given to another one and invoked from a third place. You wouldn't get anything useful.
Instead, I'd look at what you're trying to achieve here, and think of another way to get there! :)

I'm trying to call a function, and VS gives me an error (red underline), and i have the option to "generate method stub". What is this?
The generate method stub will generate you a method which looks exactly like you've written it, with the same parameters. Probably are getting this error because you've misspelled the method or because it is in a different namespace.
It means that you're trying to call the function incorrectly; check to make sure you've spelled the method name correctly, and that you're passing it the proper number and types of arguments.
It means you typed a wrong signature, so VS assumes this method doesn't exist. By using the shortcut VS can help you create the method as a stub (i.e. the signature, then you have to fill out the implementation).
ahh I had
method(button.Tag);
and a declaration of
void method(int tag)
so i fixed it with
method(int.Parse(button.Tag.toString()));
i tried that before, but I forgot to put "toString", since I thought it was already an int... stupid little mistake. thx guys
