  • How do I invoke my custom settings provider?

    - by joebeazelman
    I need to specify a different location for my settings file. After many long hours of searching, I found out that I have to write my own SettingsProvider. I succeeded in creating one which allows me to specify a path for settings file via its constructor. Programatically, I can contruct it like this: var mycustomprovider = new CustomSettingsProvider(path); The problem I am having is that there's no way to invoke my custom provider. I can decorate the VS 2008 generated setting file with the following attribute: [SettingsProvider(typeof(CustomSettingProviders.CustomSettingsProvider))] internal sealed partial class Settings { } However, the attribute doesn't allow me to construct the object with a path. Also, I want to be able to set the SettingsProvider programmatically so that I can pass in any path I want at runtime and save my settings. The examples I've seen on the net have never mentioned how to use a invoke a SettingsProvider programmatically.

  • How can I stub out a call to super in a imported Java class in JRuby for testing

    - by Doug Chew
    I am testing Java classes with RSpec and JRuby. How can I stub out a call to super in an imported Java class in my RSpec test? For example: I have 2 Java classes: public class A{ public String foo() { return "bar"; } } public class B extends A public String foo() { // B code return super.foo(); } } I am just trying to test the code in B.foo and not the code in A.foo with JRuby. How can I stub out the call to the super class method in my RSpec test? rspec test: java_import Java::B describe B do it "should not call A.foo" do # some code to stub out A.foo b = B.new b.foo.should_not == "bar" end end I have tried including a module with a new foo method in B's class hoping that it would hit the module method first but B still makes a call to A. The inserting module technique works in Ruby but not with JRuby and imported Java classes. Any other ideas to stub out the superclass method to get my RSpec test to pass?

  • C# thread with multiple parameters

    - by Lucas B
    Does anyone know how to pass multiple parameters into a Thread.Start routine? I thought of extending the class, but the C# Thread class is sealed. Here is what I think the code would look like: ... Thread standardTCPServerThread = new Thread(startSocketServerAsThread); standardServerThread.Start( orchestrator, initializeMemberBalance, arg, 60000); ... } static void startSocketServerAsThread(ServiceOrchestrator orchestrator, List<int> memberBalances, string arg, int port) { startSocketServer(orchestrator, memberBalances, arg, port); } Thank you in advance. BTW, I start a number of threads with different orchestrators, balances and ports. Please consider thread safety also.

  • bypass IIS xml file settings at file/folder level

    - by Matt Thrower
    Hi, Our site is currently set to pass all files with the xml file extension through the asp.net worker process because all the xml files on the site at the moment are generated dynamically on being hit, by writing the output directly into the response stream. However we now have a requirement to add a file which is much larger and takes several minutes to generate in this way. I wrote a console app to generate the file and set it to run nightly, but because of the global IIS setting directing xml files to run through asp_wp, it's not being served properly. I can't seem to find a way to make an exemption for the treatment of a single file in the IIS settings. Is there any other way we can do it? Cheers, Matt

  • how to set the background image property of a div to a dynamically generated image

    - by tixrus
    I have some divs and each one has its own background image. The base images as stored is just a black silhouette. What I would like to do is use the PHP GD package to modify the color of those images somewhat randomly and have the modified randomly coloured images be the background images of the divs. One way to do it is just create GD images structures from the original files, modify them, save the results as a temp file, pass this filename into the client, and then use jquery to modify the css background image properties of the divs to be the new file. But this is going to leave a lot of files laying around to garbage collect. Is there some way to do it without creating a bunch of files?

  • Selenium and HTTPS/SSL

    - by NerdyNick
    I'm running selenium-rc 1.0.3 on a Mac OS X & Windows 7 and both seem to be giving my the annoying accept cert error in firefox. In reading the docs they say I should be able to just use the *firefox run mode and rc should take care of it for me via a proxy or something, but this appears to not work. The only solution that I was able to find on the internet was to create a skeleton profile and pass the path into the rc startup, but thats not a real option. As that doesn't solve problems of testing in IE/Chrome/Safari. Does any know of any other solution that will work.

  • Can the Windows Media Player COM control play AVI files from memory (instead of from a file)?

    - by MusiGenesis
    I have a C# app, and I'm looking at using the Windows Media Player COM control to play animation and audio. So far, the only way I see of programatically controlling what the control is playing is to set its URL property to point to some file (I assume there's some way to pass in a playlist). Is there any way the WMP can render an AVI that is entirely in-memory, like a MemoryStream or something? If so, can WMP skip from one AVI to the next seamlessly (i.e. no glitch in either the audio or the video as it transitions from one to the next)? If WMP only plays files, is there some way to cue up a list of the files in advance of play start? If so, can WMP be made to skip from one file to the next without a brief interruption? Any knowledge or links to knowledge would be much appreciated.

Then I am initiating query on locked table (LOCKE TABLE users WRITE) and its just hanging, ignoring all my settings even: set_time_limit(1); ini_set('max_execution_time',1); ini_set('default_socket_timeout',1); ini_set('mysql.connect_timeout',1); I understand why set_time_limit(1) and max_execution_time is ignored but why other timeouts and especially MYSQLI_OPT_CONNECT_TIMEOUT are ignored and how to solve it. I am using PHP 5.3.1 on Windows and Linux boxes, please help.

    I'm using the following code to retrieve emails from my Gmail inbox. def get_mail Net::POP3.enable_ssl(OpenSSL::SSL::VERIFY_NONE) Net::POP3.start('pop.gmail.com', 995, "uname","pass") do |pop| unless pop.mails.empty? pop.each_mail do |mail| email = TMail::Mail.parse(mail.pop) email_obj=EmailedQueries.new email_obj.save_email(email.from,email.subject,email.body_html) end end end end This works just fine, but it retrieves only new mails from the inbox. Instead, I want a seperate function that will retrieve ALL emails from the inbox. This function will be used rarely. I wont be retrieving all mails all the time. Only when necessary. Thanks!

  • How do we calculate the filters in Mel-Frequency Cepstrum Coefficients Algorithm?

    - by André Ferreira
    After calculating the FFT and with the frequency we need to do something like this: http://instruct1.cit.cornell.edu/courses/ece576/FinalProjects/f2008/pae26%5Fjsc59/pae26%5Fjsc59/images/melfilt.png We filter the frequency spectrum with those triangles. I saw that we can use distint ways to calculcate the triangles. I will make the size of the triangles equal till 1kz and after that obtained with log function. What should we do now? With the frequency spectrum and the triangles defined.. - We should filter the frequency (frequencies limited to the triangles, if goes higher only counts till the triangle limit) and calculate the value of each triangle (and after that continue the algorithm). But when does the mel conversation happens? m = 2595 log (f/700 + 1) When do we pass from frequency to mel.. Can someone guide me in the right direction plz :d

  • How can I best geocode a table of addresses in SQL Server?

    - by ess
    I've got a SQL Server 2008 table with addresses. I've got some C# code that can individually geocode the addresses. I've got a Google Maps API for geocoding. Now I'm trying to figure out the most efficient way to use these resources. I could write a console app that manually updates the tables using my C# library, but the data I have is updated periodically. I will be performing an import routine of some sort and I'm thinking it would be 'simplest' to perform the geocoding as the import occurs. I'm not so strong on SQL Server capabilities, so I'm looking for advice. I've considered letting the import call an assembly I create that would be referenced in SQL Server, but read that Sql Server 2008 has made it virtually impossible to reference your own DLL. So my next guess is having the import call a web service to pass in the address and update the table with the results, but I've not had much luck in finding info on this method. Any advice?

  • Cross-Page communication in firefox extension

    - by OzBarry
    I have two tabs that my extension uses and I wanted to pass events back and forth between them. I've already developed a Google Chrome extension that does this via the background page api, but there doesn't seem to be an equivalent in firefox. I thought message-manager in the firefox extension docs would do the trick, but the documentation on the object is quite poor. I'd be just as happy with using one of the tabs to control the other if I can't directly import the ideas of a background page from google chrome api. Any help/guidance would be great.

  • Image Uploading - security issues

    - by TenaciousImpy
    Hi, I'm developing an ASP.NET Web app and would like the user to be able to either upload an image from their local system, or pass in a URL to an image. The image can either be a JPG or PNG. What security issues should I be concerned about doing this? I've seen various ways of embedding code within JPG files. Are there any methods in C# (or external libraries) which can confirm that a file is a JPG/PNG, otherwise throw an error? At the very least, I'm making the directory which holds uploaded images non-browsable and putting a max size limit of 1mb, but I'd like to implement further checks. Thanks for any advice.

  • pycurl script can't login to website

  • Projecting a targetting ring using direct3d

    - by JohnB
    I'm trying to draw a "targetting ring" on the ground below a "unit" in a hobby 3d game I'm working on. Basically I want to project a bright red patterned ring onto the ground terrain below the unit. The only approach I can think of is this - Draw the world once as normal Draw the world a second time but in my vertex shader I have the world x,y,z coordinates of the vertex and I can pass in the coordinates of the highlighted unit - so I can calculate what the u,v coordinates in my project texture should be at that point in the world for that vertex. I'd then use the pixel shader to pick pixels from the target ring texture and blend them into the previously drawn world. I believe that should be easy, and should work but it involves me drawing the whole visible world twice as it's hard to determine exactly which polygons the targetting ring might fall onto. It seems a big overhead to draw the whole world twice, once for the normal lit textured ground, and then again just to draw the targetting ring. Is there a better approach that I'm missing?

  • How to get objects after CoreData Context merged

    - by Emmettoc
    Hi, I tried to save data and merge with CoreData and multi-thread for iPhone app. But I can't get managed objects in the main thread after merging. I wrote code just like this: [managedObjectContext performSelectorOnMainThread:@selector(mergeChangesFromContextDidSaveNotification:) withObject:notification waitUntilDone:YES]; [self performSelectorOnMainThread:@selector(didMerged:) withObject:objectIds waitUntilDone:YES]; So I tried to pass objectIds to get NSManagedObject instances in the main thread which were generated in another thread. At first I tried "objectWithId" method but it generated fault objects. Then I tried "existingObjectWithID" method but it generated objects partly and others were nil with following Error: [Error] Error Domain=NSCocoaErrorDomain Code=133000 "Operation could not be completed. (Cocoa error 133000.)" What is wrong? Is there any way how to retrieve all objects by objectIds after merging in another thread? Thank you.

  • How Can I Check an Object to See its Type and Return A Casted Object

    - by Russ Bradberry
    I have method to which I pass an object. In this method I check it's type and depending on the type I do something with it and return a Long. I have tried every which way I can think of to do this and I always get several compiler errors telling me it expects a certain object but gets another. Can someone please explain to me what I am doing wrong and guide me in the right direction? What I have tried thus far is below: override def getInteger(obj:Object) = { if (obj.isInstanceOf[Object]) null else if (obj.isInstanceOf[Number]) (obj:Number).longValue() else if (obj.isInstanceOf[Boolean]) if (obj:Boolean) 1 else 0 else if (obj.isInstanceOf[String]) if ((obj:String).length == 0 | (obj:String) == "null") null else try { Long.parse(obj:String) } catch { case e: Exception => throw new ValueConverterException("value \"" + obj.toString() + "\" of type " + obj.getClass().getName() + " is not convertible to Long") } }

  • Memory cleanup on returned array from static method (objective-c)

    - by Michael Bordelon
    In objective-c, I have a utility class with a bunch of static methods that I call for various tasks. As an example, I have one method that returns an NSArray that I allocate in the static method. If I set the NSArray to autorelease, then some time later, the NSArray in my calling method (that is assigned to the returned pointer) losses it's reference because the original form the static method is cleaned up. I can't release the NSArray object in the static method because it needs to be around for the return and assignment. What is the right way to return an object (like the NSArray) from a static class, and have it hang around for the calling class, but then get cleaned up later when it is no longer needed? Do I have to create the object first in the caller and pass in a pointer to the object and then return that same object form the static method? I know this is a basic O-O problem, I just never had this issue in Java and I do not do much C/C++. Thanks for your help.

  • Which method of creating javascript objects is better?

    - by Germaine
    I've seen objects defined in two different ways, which function similarly, but are, of course, fundamentally different. You can do it either like this: var myobject = {property: 'hello', act: function() { this.property += ' world'; }}; and like this: function myobject() { this.property = 'hello'; this.act = function() { this.property += 'world'; } } The second method could create objects like so var newobj = new myobject(); but you could do something similar using the first notation by making the object the return value of a function. The new keyword has the advantage of being able to pass parameters that can be used to initialize the properties of the object, but you could just as easily add an init function to the first kind of object. Just wondering if besides these two differences, if there was a fundamental difference that made one method definitely better than the other method.

  • Next, Previous Records Using Named Scope

    - by keruilin
    I have a model for which I want to retrieve the next record(s) and previous record(s). I want to do this via a named_scope on the model, and also pass in as an argument the X number of next/previous records to return. For example, let's say I have 5 records: Record1 Record2 Record3 Record4 Record5 I want to be able to call Model.previous or Model.previous(1) to return Record2. Similarly, I want to be able to call Model.next or Model.next(1) to return Record4. As another example I want to be able to call Model.previous(2) to return Record3. I think you get the idea. How can I accomplish this?

  • How do laziness and I/O work together in Haskell?

    - by Bill
    I'm trying to get a deeper understanding of laziness in Haskell. I was imagining the following snippet today: data Image = Image { name :: String, pixels :: String } image :: String -> IO Image image path = Image path <$> readFile path The appeal here is that I could simply create an Image instance and pass it around; if I need the image data it would be read lazily - if not, the time and memory cost of reading the file would be avoided: main = do image <- image "file" putStrLn $ length $ pixels image But is that how it actually works? How is laziness compatible with IO? Will readFile be called regardless of whether I access pixels image or will the runtime leave that thunk unevaluated if I never refer to it? If the image is indeed read lazily, then isn't it possible I/O actions could occur out of order? For example, what if immediately after calling image I delete the file? Now the putStrLn call will find nothing when it tries to read.
