  • Where can I find a good guide to writing C Collections?

    - by Mike Axiak
    I remember having read a very good guide to writing collections. By that I mean, it described using macros to generate types with type parameters, kind of like C++ templates. I'm not sure if it was written by Rusty Russell, but it was someone I recognized. It was posted on hackernews or proggit... I wanted to write a new C library and has searched google for the past 30 min for this guide to no avail. Anybody remember?

  • linq to sql loadwith vs associatewith

    - by stackoverflowuser
    what is the difference between loadwith and associatewith. From the articles i read it seems that loadwith is used to load addition data (eg all orders for the customers). While AssociateWith is used to filter data. Is that a correct understanding? Also it will be nice if someone can explain this with an example based explanation.

  • How to publish a list of integers?

    - by Mason Wheeler
    I want to make a component that includes a list of integers as one of its serialized properties. I know I can't declare a TList<integer> as a published property, because it doesn't descend from TPersistent. I've read that you can define "fake" published properties if you override DefineProperties, but I'm not quite sure how that works, especially when it comes to creating a fake property that's a list, not a single value. Can someone point me in the right direction?

  • CruiseControl.NET : Sending email using SVN username to ActiveDirectory mapping

    - by matthewpe
    Is it possible to configure CruiseControl.NET to send an email to the user(s) that did modifications to a broken build by mapping their SVN username to the corresponding Active-Directory alias (hence retrieving the correct, updated email address). Our SVN server is set-up to allow users of a certain Active-Directory group to read and commit changes: I don't want to have to maintain the CruiseControl.NET config every time a user gets added to our Programmers group in Active-Directory. Thanks a lot!

  • Obtain user activity data in emails after I programmatically mail out emails

    - by John
    If I were to build a newsletter emailing system, I will need to be able to generate reports on how many emails bounced, flagged as spam, unsubscribed, read vs. unread, click through rates etc.... So how do you keep track of user activity after the email has been sent? Am I right in assuming that you CAN NOT embed javascript code into emails to monitor user activity? How else do I gather data for my reports?

  • REST, HTTP verbs and current development in .NET and silverlight

    - by vtortola
    Hi, I've read several posts in the internet about that Silverlight only supports GET and POST, and that the most of the web browsers too. Is this true? has it changed lately? I'm developing a RESTful web service for a Silverlight application, still in early stage, and I'd like to know if I should use just POST and GET, or otherwise I could use PUT and delete. Cheers

  • Web.Config issue with Unit Testing

    - by LeeHull
    I am trying to unit test a lot of my MVC controllers, but unfortunately it keeps failing because it needs a lot of settings from the web.config.. Which I copied over but does not read it, what I'm needing is the membership and rolemanager but I can't just add it to the app.config either, which I've been able to get the connection strings and application settings to work with.. Any idea how to get the web.config to work with MSTest?

  • Understanding Haskell's filter

    - by dmindreader
    I understand that Haskell's filter is a high order function (meaning a function that takes another function as a parameter) that goes through a list checking which element fulfills certain boolean condition. I don't quite understand its definition: filter:: (a->Bool)->[a]->[a] filter p [] = [] filter p (x:y) | p x = x:filter p y | otherwise = filter p y I understand that if I pass an empty list to the function, it would just return an empty list, but how do I read the last two lines?
