• Can you still do variable arguments in C the old way?

  Purely for interest, I am re-learning C after ... I don't know ... 15 - 20 years. I seem to recall that variable arguments were implemented as simple macros. Can anyone remember what they were? Will they still work today?

• Passing parameter to base class constructor or using instance variable?

  - by deamon

  All classes derived from a certain base class have to define an attribute called "path". In the sense of duck typing I could rely upon definition in the subclasses: class Base: pass # no "path" variable here def Sub(Base): def __init__(self): self.path = "something/" Another possiblity would be to use the base class constructor: class Base: def __init__(self, path): self.path = path def Sub(Base): def __init__(self): super().__init__("something/") What would you prefer and why? Is there a better way?

• How do I customize the ASP.Net Bubble Event to pass an additional variable?

  - by CowKingDeluxe

  I am using BubbleEvent to give events from a web user control to its parent (which is a Default.aspx with code behind page). I would like to use BubbleEvent to not only pass the sender and event, but also an integer or another variable. Is there a way to add a parameter to the BubbleEvent, or is there a different way I should be approaching this?

• Syncing Data to Remote Services, Best Practices for Caching?

  - by viatropos

  I want to be able to publish events to Eventbrite, Eventful, and Google Calendar for my Google Apps. Each service has slightly different properties for events... I will be syncing many other things too, such as users with Google Contacts and MailChimp, Documents with Google Docs and some other services, etc... So I'm wondering, what is the recommended way of retrieving the data for the end user so that it's reasonably maintainable and optimized? Here are the things I'm thinking that I'm having trouble with: My App keeps a central database of all the models (Event, Document, User, Form, etc.), and whenever Admin creates an object (e.g. create through Eventbrite or through our Admin panel), we sync them and store a copy in our local database. When User goes to the site /events, App retrieves the events from the database. Read Events from a target feed, such as the Eventbrite or Eventful feed, and scrap the local database. Basically, I'm wondering, if we're storing all of the data on a remote service, do we really need to have a local database copy of the data? When would we need to have a local database, when wouldn't we?

• Why does 'url' not work as a variable here?

  - by kryptobs2000

  I originally had the variable cpanel named url and the code would not return anything. Any idea why? It doesn't seem to be used by anything else, but there's gotta be something I'm overlooking. import urllib2 cpanel = 'http://www.tas-tech.com/cpanel' req = urllib2.Request(cpanel) try: handle = urllib2.urlopen(req) except IOError, e: if hasattr(e, 'code'): if e.code != 401: print 'We got another error' print e.code else: print e.headers print e.headers['www-authenticate']

• How to store the hostname in a variable in a .bat file?

  - by eqbridges

  I would like to convert this /bin/sh syntax into a widely compatible Windows batch script: host=`hostname` echo ${host} How to do this so that it'll work on any Windows Vista, Windows XP, and Windows 2000 machine? To clarify: I would then like to go on in the program and use the hostname as stored in the variable host. In other words, the larger goal of the program is not to simply echo the hostname.

• In Silverlight programming, how to prevent visitors from caching the downloaded content?

  - by suugaku

  Hi all, I want to create an online quiz website using Silverlight. When the registered users are logged in, they can view and answer the quiz once per page. To proceed to the next question, they must push next button, and the new data downloaded from the server. The previous questions are not cached. Thereby everytime the question is requested, the question will be reloaded from the server again. My question is how to do my scenario above in silverlight? Thank you in advance.

• What is the origin / meaning of these variable naming conventions?

  - by Andrew Hubbs

  What is the general meaning and where did it start to have variables with leading or trailing underscores? ex: _varName and varName_ I have always thought a leading underscore indicated the variable was a pointer but I don't know where I got this idea. Recently I have seen these naming conventions used in Java which makes that reasoning completely wrong.

• In C++, what happens when you return a variable?

  - by wowus

  What happens, step by step, when a variable is returned. I know that if it's a built-in and fits, it's thrown into rax/eax/ax. What happens when it doesn't fit, and/or isn't built-in? More importantly, is there a guaranteed copy constructor call? edit: What about the destructor? Is that called "sometimes", "always", or "never"?

• How can I save shell output to a variable in LaTeX?

  - by Frank

  I need to be able to execute a shell command through LaTeX [*] and have the resulting output available for use later on in the form of a LaTeX 'variable' (e.g., via a subsequent \newcommand command). If necessary a temporary file could be used to hold the output, although I would like to avoid this. I have been able to use \immediate\write18 to invoke a bash command before, but this was only used to write to a temporary file. [*] I realise that the -shell-escape flag must be set for this to be allowed

• How do I create a "global variable" in Java such that all classes can access it?

  - by Chrystle Soh

  here's my problem: I have multiple classes that are part of the same package and they need access to a certain file path String filePath = "D:/Users/Mine/School/Java/CZ2002_Assignment/src/" Rather than declaring the same Filepath in every single class, is it possible to simply have a "global" type of variable of this FilePath so that all classes can access it and I only need to declare and update it once. Thanks
