  • MVVM Tutorial/Example Code with internet connectivity

    - by SpikeX
    I understand the View and ViewModel portions of MVVM, but what I'm still really fuzzy on is how you connect your application to data sources on the Internet (say you're grabbing some XML or JSON from the web), and specifically, where that code goes in your application. Can someone provide or link to some example code or a tutorial that walks you through setting up a simple WPF (or Silverlight) application that fetches data from the Web?

  • Is there a way to use rsync and exclude files greater than a certain size?

    - by milesmeow
    I've checked out the man pages and did some searching but can't find info on ways to have rsync skip files greater than a certain size. We're doing rsync to an offline location and when someone puts a hug video file, the rsync jobs run into work hours. I've looked at the 'exclude' syntax and didn't see anything for excluding based on file size. Can I do it with rsync or should I look for other offline synching alternatives?

    - by HH
    Format is like: CHINA;2002-06-25 00:00:00.000;5,60 CHINA;2002-06-26 00:00:00.000;5,32 CHINA;2002-06-27 00:00:00.000;5,31 and I try to use Python's CSV tools to parse it but cannot understand the paragraph, source: And while the module doesn’t directly support parsing strings, it can easily be done: import csv for row in csv.reader(['one,two,three']): print row Could someone clarify the line ['one,two,three']?

  • Databank for city information

    - by Kimble
    I'm hacking on a semi commercial(ads) travel related web site and would like to add a couple of lines about the biggest cities in Europe. Just a few lines about what (if anything) the city is known for, main attractions and so on. Can someone recommend me a data source with a compatible license? Bonus points for being easily importable.

  • Are fragments of hashes collision-resistent?

    - by Mark
    Let me see if someone would mind clearing up this elementary point about md5 and hashing. If you only use the first 4 bytes of an md5 hash, would that mean theoretically only 1 in 255^4 chance of collision. iow is that the intention with it (and other hash algorithms) - that you only have to use a small portion of the returned hash (say the hash is of a file of some size).

    if i use the custom css generator on their webpage i can have a wider width than 960? so isnt the name 960 kind of misleading? and some persons say that you cant have a flexible grid system (that changes with your browser size) with 960. but you can download a fluid version from the custom css generator. so apparently they didnt know what they were talking about? would be great if someone could straight these things out.

  • Classic ASP shopping cart discounts

    - by Neil Bradley
    Hi there, I have a Classic ASP shopping cart, but I need to add in an option to enter a promo code and (if valid) apply a discount to the total. There is a promo codes table that stores the promotional codes and the value of the discount to apply. So I was wondering if someone might be able to help me integrate this? Happy to pay for the time. I think it may only take an hour or so at most. :S

  • How to use LINQ for CRUD with a simple SQL table?

    - by Rob Ferno
    Every LINQ blog I found there seemed around 2 years old, I understand the syntax but need more direction on creating the SQL mapping and context classes. I just need to use LINQ for 2 SQL tables I have, nothing complicated. Do folks write the SQL mapping classes by hand for such cases or is there a decent tool for this? Can someone point me in the right direction?

  • Crackers - How do they do it, how do we fight back?

    - by zedo
    As someone who is interested in learning more about the security side of technology, I ask you all the following questions: How is it that crackers crack software? What techniques are used to do so? I would imagine that the cracking methods depend upon the language the software is written in, right? Aside from using something like cloud-based security for SaaS ((software as a service) which isn't always an option), what choices does one have to prevent their software from being compromised?

    - by Pato
    Hello All! Could someone please explain what the difference is between using the ISupportInitialize interface methods (BeginInit/EndInit) and using SuspendLayout/ResumeLayout? Is ISupportInitialize ONLY used during construction/"initial" initialization... or can it be used later when you want to add new child controls to an existing parent control? Any particular differences? I greatly appreciate your help! Thank you, Pato

  • Building a balanced binary search tree

    - by Znarkus
    Hi! Is there a method to build a balanced binary search tree? Example: 1 2 3 4 5 6 7 8 9 5 / \ 3 etc / \ 2 4 / 1 I'm thinking there is a method to do this, without using the more complex self-balancing trees. Otherwise I can do it on my own, but someone probably have done this already :)

I have XCode 3.2.3 (Pre Release with OS 4 beta) and I started to create my application, after the final touches and everything worked ok, I changed the Simulator - 4.0 to Simulator - 3.1.3 (latest iPhone OS) and I could never start my app again :-( Does anyone know what I should do? I created a simple Screencast of the problem so everyone can see what I'm writing about. Thank you for all the help.

    - by stas
    I want to make a website that will have multiple pages, but because of a unique navigation bar, I cannot simply link to a new file for each page. What is the best way to accomplish this. Some possibilities that I can think of are having all of them on one page, but using css and javascript to move the other pages offscreen, or using iframes and loading them with javascript. Could someone please direct me to some examples or tutorials?
