  • How do I supply values to an referenced assembly without calling a method it explicitly?

    - by Rob
    Currently I have a static class that I use as my logging module. I’ve added the class to my visual studio solution. Within the class I’ve specified the name and location of the log file to use. Which lets me do stuff like this – which I like and want. Logger.Information(“Page_Load”,”controls loaded correctly”); I’d like to refactor the code and move the logging functionality into a separately compiled assembly, if I did this I would then need to pass in the log file name and location to save the files too. However I don’t want to have to supply this information every time I call the ‘Logging’ method, this would be bad... Logger.Informtaion(“Page_Load”,”controls loaded correctly”,”logfile.txt”,”c:\temp”); Is there any way I can supply this information without having to specify it within each page or via the method call.

  • What's a good, threadsafe, way to pass error strings back from a C shared library

    - by PerilousApricot
    Hello, all- I'm writing a C shared library for internal use (I'll be dlopen()'ing it to a c++ application, if that matters). The shared library loads (amongst other things) some java code through a JNI module, which means all manners of nightmare error modes can come out of the JVM that I need to handle intelligently in the application. Additionally, this library needs to be re-entrant. Is there in idiom for passing error strings back in this case, or am I stuck mapping errors to integers and using printfs to debug things? Thanks!

  • Correct way to protect a private API key when versioning a python application on a public git repo

    - by systempuntoout
    I would like to open-source a python project on Github but it contains an API key that should not be distributed. I guess there's something better than removing the key each time a "push" is committed to the repo. Imagine a simplified foomodule.py : import urllib2 API_KEY = 'XXXXXXXXX' urllib2.urlopen("http://example.com/foo?id=123%s" % API_KEY ).read() What i'm thinking is: Move the API_KEY in a second key.py module importing it on foomodule.py; i would then add key.py on .gitignore file. Same as 1 but using ConfigParser Do you know a good programmatic way to handle this scenario?

  • Automatically registering "commands" for a command line program in python

    - by seandavi
    I would like to develop a command-line program that can process and give "help" for subcommands. To be concrete, say I have a single script called "cgent" and I would like to have subcommands "abc", "def", and "xyz" execute and accept the rest of the sys.args for processing by optparse. cgent abc [options] cgent help abc .... All of this is straightforward if I hard-code the subcommand names. However, I would like to be able to continue to add subcommands by adding a class or module (?). This is similar to the idea that is used by web frameworks for adding controllers, for example. I have tried digging through pylons to see if I can recreate what is done there, but I have not unravelled the logic. Any suggestions on how to do this? Thanks, Sean

  • Execute PHP after new Order in Magento

    - by Israel Lopez
    Hello There, I'm trying to figure out where I could drop in some PHP code to notify a CRM we are using (Solve360) that a new order has been placed, and that an event should be created (API) to fulfill the order. Order Product Checkout Complete Checkout & Capture CC Side notify CRM Done Not sure where to start, but I have had to make some small tweaks to fix the Quantum Gateway payment processor to work. In that module it appears that the objects for the order (email, amt, details) were available. However it seems it would be quite 'dirty' to insert more PHP code in there. Ideas? PHP 5.2.x & Magento 1.4.x

  • Why isn't my IO executed in order?

    - by HaskellElephant
    Hi, I'm having some fun learning about the haskell IO. However in my recent exploration of it I have encountered some problems with IO not executing in order, even inside a do construct. In the following code I am just keeping track of what cards are left, where the card is a tuple of chars (one for suit and one for value) then the user is continously asked for wich cards have been played. I want the putStr to be executed between each input, and not at the very end like it is now. module Main where main = doLoop cards doLoop xs = do putStr $ show xs s <- getChar n <- getChar doLoop $ remove (s,n) xs suits = "SCDH" vals = "A23456789JQK" cards = [(s,n) | s <- suits, n <- vals] type Card = (Char,Char) remove :: Card -> [Card] -> [Card] remove card xs = filter (/= card) xs

  • What was the most productive improvement suggestion you ever made for your team

    - by questzen
    I suggested the testing and functional teams to use Freemind map for jotting the functional flows and test steps. There was some paranoia but our module took it up and the QA teams were surprised to see near zero review comments. There was misconception among the team that there are doing more work. I assured them that by the time others would complete their work along with comment fixes, we would be going out for team lunchs and we did. The real returns came when the developers started refering to the created document in their discussions. So share your contribution(s).

  • Java technologies for web-development.

    - by Alex
    Hello. I'm PHP-programmer, but I'm extremely interested in learning Java. So I decided to change speciality from PHP to Java. At the moment I have an opportunity to try to make quite simple web-application (it should contain 2-3 forms, several pages with information from the database and authorization module) and also I have a chance to choose any technology I want. Besides I have about 3 months for this task. I've decided to develop site with Java technologies for the purpose of studying. I've already read a book about Java ("Java2 Complete Reference" by P.Naughton) and currently I'm reading "Thinking in Java" by B.Eckel. I clearly understand it's not enough for efficient development, but I want, at least, to try. I would be very appreciated for the advises, which framework (for example) or technology to choose (Spring, Grails etc.) and what primary aspects and technologies of Java should I pay attention to? Thank you in advance.

  • Drupal removing javascript from Full HTML link

    - by Jen
    I am new to Drupal and am trying to create a node (let's call it child) that will only really be accessed when clicked on from another node (we'll call it parent). When closing the child window, I want to parent window to refresh. Outside of Drupal, that's easy: <a onclick="window.close(); window.opener.location.reload();" href="#">Click to close this window</a> However, when I type this into the body of a node using Full HTML, it still strips the onclick text from my post. How can I include javascript in the body of a node like this? Is there a special module I need. Thanks!

  • How can I pass an object as a parameter in the google app engine RPC flow?

    - by jimmartens
    I'm building a pretty basic app, and one thing I want to do is pass an object as a parameter up through the service - async - impl instead of passing up a million separate parameters. so in async, I do something like this: import shared.Profile; ... public interface ProfileServiceAsync { public void addProfile(Profile inProf, AsyncCallback<Void> async); Now, profile is a class in com. ... .shared and I have the following in my ... .gwt.xml <source path='shared'/> That being said when I try to compile I get this error. [ERROR] Errors in 'file:/D:/projects/eclipse/workspace/.../src/com/.../client/ProfileServiceAsync.java' [ERROR] Line 11: No source code is available for type shared.Profile; did you forget to inherit a required module? Any ideas on this?

  • Python: Using `copyreg` to define reducers for types that already have reducers

    - by cool-RR
    (Keep in mind I'm working in Python 3, so a solution needs to work in Python 3.) I would like to use the copyreg module to teach Python how to pickle functions. When I tried to do it, the _Pickler object would still try to pickle functions using the save_global function. (Which doesn't work for unbound methods, and that's the motivation for doing this.) It seems like _Pickler first tries to look in its own dispatch for the type of the object that you want to pickle before looking in copyreg.dispatch_table. I'm not sure if this is intentional. Is there any way for me to tell Python to pickle functions with the reducer that I provide?

  • How to solve recursion relations in mathematica efficiently?

    - by Qiang Li
    I have a recursion to solve for. f(m,n)=Sum[f[m - 1, n - 1 - i] + f[m - 3, n - 5 - i], {i, 2, n - 2*m + 2}] + f[m - 1, n - 3] + f[m - 3, n - 7] f(0,n)=1, f(1,n)=n However, the following mma code is very inefficient f[m_, n_] := Module[{}, If[m < 0, Return[0];]; If[m == 0, Return[1];]; If[m == 1, Return[n];]; Return[Sum[f[m - 1, n - 1 - i] + f[m - 3, n - 5 - i], {i, 2, n - 2*m + 2}] + f[m - 1, n - 3] + f[m - 3, n - 7]];] It takes unbearably long to compute f[40,20]. Could anyone please suggest an efficient way of doing this? Many thanks!

  • Use C function in C++ program; "multiply-defined" error

    - by eom
    I am trying to use this code for the Porter stemming algorithm in a C++ program I've already written. I followed the instructions near the end of the file for using the code as a separate module. I created a file, stem.c, that ends after the definition and has extern int stem(char * p, int i, int j) ... It worked fine in Xcode but it does not work for me on Unix with gcc 4.1.1--strange because usually I have no problem moving between the two. I get the error ld: fatal: symbol `stem(char*, int, int)' is multiply-defined: (file /var/tmp//ccrWWlnb.o type=FUNC; file /var/tmp//cc6rUXka.o type=FUNC); ld: fatal: File processing errors. No output written to cluster I've looked online and it seems like there are many things I could have wrong, but I'm not sure what combination of a header file, extern "C", etc. would work.

  • Drupal, Video: why the thumbnails image src links to a video instead of an image ?

  • Weird behaviour with optparse and bash tab completion

    - by PulpFiction
    Hi I am building a script for users new to Linux, so please understand why I am asking this :) My script runs like this: python script.py -f filename.txt I am using the optparse module for this. However, I noticed the following when doing tab completion. The tab completion works when I do: python script.py <tab completion> # Tab completion works normally as expected But it does not work when I do it like this: python script.py -f <tab completion> # No type of tab completion works here. I really don't want my users typing the name of the input file. Tab completion is a must. How can I get it working or what am I doing wrong here?

  • Rails 3 respond_with, route constraints and resources

    - by Intelekshual
    I'm building a versioned API, so I have the following nested controllers: ApiController < ApplicationController Api::V1Controller < ApiController Api::V1::EventsController < Api::V1Controller The API is accessed via a subdomain. I have the following routes: constraints(:subdomain => "api") do scope :module => 'api' do namespace :v1 do resources :events end end end This produces the type of URL I want (/v1/events). The problem I'm facing is when using responds_with in Api::V1::EventsController. Just doing something as simple as the below fails with the error too few arguments: def index @events = Event.all respond_with(@events) end I know respond_width is meant to be used with resources, but I'm not sure how the events resource should be accessed from the constrained, scoped, and namespaced route. I can output other things (such as current_user), just not an array of events. Help?

  • Realtime processing and callbacks with Python and C++

    - by Doughy
    I need to write code to do some realtime processing that is fairly computationally complex. I would like to create some Python classes to manage all my scripting, and leave the intensive parts of the algorithm coded in C++ so that they can run as fast as possible. I would like to instantiate the objects in Python, and have the C++ algorithms chime back into the script with callbacks in python. Something like: myObject = MyObject() myObject.setCallback(myCallback) myObject.run() def myCallback(val): """Do something with the value passed back to the python script.""" pass Will this be possible? How can I run a callback in python from a loop that is running in a C++ module? Anyone have a link or a tutorial to help me do this correctly?

  • Running script constantly in background: daemon, lock file with crontab, or simply loop?

    - by Mauritz Hansen
    I have a Perl script that queries a database for a list of files to process processes the files and then exits Upon startup this script creates a file (let's say script.lock), and upon exit it removes this file. I have a crontab entry that runs this script every minute. If the lockfile exists then the script exits, assuming that another instance of itself is running. The above process works fine but I am not very happy with the robustness of this approach. Specifically, if for some reason the script exits prematurely and the lockfile is not removed then a new instance will not execute properly. I would appreciate some advice on the following: Is using the lock file a good approach or is there a better/more robust way to do this? Is using crontab for this a good idea or could I better write an endless loop with sleep()? Should I use the GNU 'daemon' program or the Perl Proc::Daemon module (or some other equivalent) for this?

  • Why doesn't Python's `re.split()` split on zero-length matches?

    - by Tim Pietzcker
    One particular quirk of the (otherwise quite powerful) re module in Python is that re.split() will never split a string on a zero-length match, for example if I want to split a string along word boundaries: >>> re.split(r"\s+|\b", "Split along words, preserve punctuation!") ['Split', 'along', 'words,', 'preserve', 'punctuation!'] instead of ['', 'Split', 'along', 'words', ',', 'preserve', 'punctuation', '!'] Why does it have this limitation? Is it by design? Do other regex flavors behave like this?

  • rake tast can't access rails.cache

    - by mark
    Hi I want to call a rake task from a cron job that stores remote weather data in the rails cache. However, I must be doing something pretty wrong here because I cannot find any solution through countless fruitless searches. Say I define and call this task namespace :weather do desc "Store weather from remote source to cache" task :cache do Rails.cache.write('weather_data', Date.today) end end I get the error Anonymous modules have no name to be referenced by Which leads me to believe the rails cache isn't available. Outputting Rails.class from the rake file gives me Module but Rails.cache.class again returns the above error. Do I need to include something here? Am I just hopeless at internet? :) Thanks in advance.

  • IIS7 and ARR as reverse proxy for Subversion

    - by Paul Stovell
    I am using IIS7 and the Application Request Routing extension to act as a reverse proxy to Subversion running on Apache. The proxy works fine and I am able to explore the server, and even perform a "check out". However, I cannot browse to files that would normally be forbidden by ASP.NET - for example, .cs, .csproj, and so on. Files ASP.NET wouldn't be concerned with - such as .txt - are fine. I tried to edit the global web.config to remove the Forbidden handler mapping for these files, but it did not seem to make a difference. Is there any way to allow the URL rewriting module in IIS7 to work, while allowing all file extensions to be rendered?

How can I display the validation errors in this form? using setTemplate('index') doesn't work because I would have to pass the id=1 to it... thanks
