• How do I best implement my Windows desktop and service C# applications automatic updates?

  - by Ivan

  My project contains WinForms, WPF, and Windows Service programs running on users' office desktop PCs. I want these applications to periodically check for new versions available at specific URL, automatically download new versions and replace themselves with new versions without attracting any user attention (keeping in mind that users may run Windows from XP to 7 and work using non-privileged account (which can be part of active directory)). Alternatively the whole update package has to be able to be distributed as an unattended-installed MSI package. Any recommendations on implementing this?

• Remove extra junk from C proprocessor?

  - by Brendan Long

  I'm trying to use the C proprocessor on non-C code, and it works fine except for creating lines like this at the top: # 1 "test.java" # 1 "<built-in>" # 1 "<command-line>" # 1 "test.java" The problem is that these lines aren't valid in Java. Is there any way to get the preprocessor to not write this stuff? I'd prefer not to have to run this through something else to just remove the first 4 lines every time.

• How to crop scanned image using C#?

  - by ieaglle

  I have a scanned image of a book page and i need to crop this scan for leaving only page area. I tried to use AForge to detect page borders, but it doesn't work because the space which i need to crop may consist of little "light" areas (due to scanner quality) and edge detector detects borders there. That's why this is bad idea as for me. Could you recommend something? P.S. Please don't tell me to use non-free libraries.

• How did my reputation drop over night from 901 points to 471? [closed]

  - by AspOnMyNet

  I'm not sure how important it is having a large reputation number, but then I'm also worried someone hacked into my account or something, since I don't see how else it would be possible to loose 500 points in a single day ( hopefully this non-programming related post won't cause another 500 drop :) ). Any idea why this happened? thanx

• python: a way to get an exhaustive, sorted list of keys in a nested dictionary?

  - by saidimu

  exhaustive: - all keys in the dictionary, even if the keys are in a nested dictionary that is a value to a previous-level dictionary key. sorted: - this is to ensure the keys are always returned in the same order The nesting is arbitrarily deep. A non-recursive algorithm is preferred. level1 = { 'a' : 'aaaa', 'level2_1' : {'b': 'bbbbb', 'level3': {'c': 'cccc', 'd': 'dddddd'} }, 'level2_2' : { 'z': 'zzzzzzz' } }

• AJAX, Subdomains and the 200 OK response.

  - by b. e. hollenbeck

  A non-hypothetical but abstracted situation: I have a domain www.foo.com, from which I'm making an AJAX POST to beta.foo.com. Examining the XHR object, I see a response header of 200 OK, but no response text - I even get a response 12B long, which is the exact response (a 12-character string) that I'm expecting - but the response text is blank. If this is a cross-domain issue, why am I getting 200 OK, and better yet - why am I seeing the PHP functions fire on the beta.foo.com side - yet getting no response?

  - by sprugman

  I created a bunch of nodes using node_save(). Unfortunately, I forgot to turn on the Automatic alias setting on them. Anyone know how I can do that now? I can't figure out where in the db that setting is stored. (Other non-db approaches are fine, too.)

• How do you save the state of a computation in while using SNOW (or Multicore or ...)

  - by James

  From hard experience I've found it useful to occasionally save the state of my long computations to disk to start them up later if something fails. Can I do this in a distributed computation package in R (like SNOW or multicore)? It does not seem clear how this could be done since the master is collecting things from the slaves in a non-transparent way.

• Unresponsive Clojure REPL after exception

  - by Hendekagon

  If I start a REPL and then do something that throws an exception like (use 'non-existent-thing) ** then after that the REPL ceases to evaluate anything I enter. Is there a special key I can press to make it turn round, face me, uncross its arms and listen once more ? Or must I ctrl-d, restart, type everything up to where I was and get it right this time ? ** which results in: Exception in thread "Thread-1" java.lang.RuntimeException: java.io.FileNotFoundException: Could not locate non_existent_thing__init.class or non_existent_thing.clj on classpath: (NO_SOURCE_FILE:0)

• How to convince management that reformatting entire java code base is safe

  - by jtsampson

  How would one go about proving to management that a batch reformat of all .java files in a large code base (to place the code in compliance with the company's coding standards) is safe and will not affect functionality. The answers would have to appease the non-technical and the technical alike.

  I have a winforms app that needs to write out logs. The app also needs to run without UAC warnings and using a non-admin account.

• Is there a sample Rails application with a number of cucumber stories?

  - by Otto

  I'm trying to really understand Cucumber stories. I get it, but I'm really slow writing them. I think if I saw a good fleshed out application, I'd get closer to where I want to be. There are some samples out there, but there aren't any I can find with a single app with some non-contrived example stories. Are there any existing ones?

• Count white spaces to the left of a line in a text file using C++

  - by insertable

  Hi all, I am just trying to count the number of white spaces to the LEFT of a line from a text file. I have been using count( line.begin(), line.end(), ' ' ); but obviously that includes ALL white spaces to the left, in between words and to the right. So basically what I'm wanting it to do is once it hits a non-space character stop it from counting the white spaces. Thanks everyone.
