• Calling functions from main() in c++

  - by Supriyo

  Hello. I have a programme that has about 100 classes and more than 1000 functions spread over 20 header and source code files. What I want to know is that how I can pass arguments to so many functions in so many files? What is the procedure adopted for this in main()? Regards, Supriyo

• Any way in C++ to forward declare a function prototype?

  - by jsyjr

  I make regular use of forward class declarations and pointers to such classes. I now have a need to pass a function pointer through a number of layers. I would prefer to include the header that declares my function pointer's prototype only into the module that dereferences a function pointer rather than into each layer that simply passes along that pointer value. Is this possible?

• How to add debug information when compiling with Java's Compiler API

  - by Henrik Paul

  What do I need to do to control whether my classes compiled with a JavaCompiler will include debug information or not? I'm thinking it has something to do with the getTask()-method's options parameter, but I can't find any references on whether that assumption is correct to start with, and if so, what is the correct way to control that?

  - by dejaninic

• Help me to find a better approach-Design Pattern

  - by DJay

  I am working on an ASP.Net web application in which several WCF services are being used. At client level, I am creating channel factory mechanism to invoke service operations. Right now, I have created an assembly having classes used for channel factory creation code for every service. As per my assumption this is some sort of facade pattern. Please help me to find a better approach or any design pattern, which I can use here.

• How to emulate OOP with C?

  - by Francisco Garcia

  I would like to know which articles or books are good to use OOP concepts in C. I mean things like using function pointers to emulate classes, strict naming conventions to emulate namespaces, and things like that. Also a reference about how to code in C different types of UML diagrams would be great.

• How can I serve up color-coded Java code using PHP?

  - by Eric

  I'd like to embed code from my SVN repository into my website, using PHP. The SVN has public anonymous access, so the PHP code should be fine reading it. The code on said SVN is java, and so far I've had no luck finding a syntax-highlighter to make the code more readable. Ideally I'd like one that uses CSS classes so that I can change the colors to match the look of the website. Could someone point me to a PHP library that highlights Java code?

• In .NET, How do I separate xml from compiled resource file?

  - by Brandon

  We have a customer that would like to modify application user messages that we store in .resx files. I'm thinking this can't be done since the xml file behind the .resx is embedded in a compiled dll. Am I correct? Or, is there a way keep the xml outside of the compiled dll? I realize this can easily be done by other means but I like the ease of the resx file--the classes/properties are created for you.

• 1K incoming http post requests per second, each with a 10-50K file

  - by Blankman

  I'm trying to figure out what kind of server setup I will need to support: 1K http post requests per second each post will contain a xml file between 5-50K (average of 25 kilobytes) Even if I get a 100 Mb/s connection with my dedicated box (they usually give 10 Mb/s but you can upgrade), from my calculations that is about 12K kb/s which means about 480 25kb files per second. So this means I need around 3 servers then, each with 100 Mb/s connection. Would a single server running HAProxy be able to redirect the requests to other servers or does this mean I need to get something else that can handle more than 100 Mb/s to proxy things out to the other servers? If my math is off I'd appreciate any corrections you may have.

• Custom Visual Studio 2008 Designer

  - by Mick

  How do I create a custom Visual Studio 2008 UI designer for a C# file? For example, when you double click on a DataSet in the Solution Explorer, a UI screen appears that allows you to edit the DataSet, even though it is defined in XML/code (which you can right click and "View Code"). Usually this code is separated from user code in some way, either by region ("Windows Forms Designer Generated Code"), by codegen (".g.cs" for WPF XAML files), or some other means like partial classes.

• uploading files greater than 1MB = connection resets

  - by Legit

  I'm using nginx on the frontend as "proxy cache" and apache on the backend, i've set my PHP settings to the following: error_log = /var/www/site1/php_error.log error_reporting = 22527 file_uploads = On log_errors = On max_execution_time = 0 max_file_uploads = 20 max_input_time = -1 memory_limit = 512M post_max_size = 0 upload_max_filesize = 1000M What's the problem? Uploading files less than 1MB is successful but anything greater than that, Google Chrome outputs: Error 101 (net::ERR_CONNECTION_RESET): The connection was reset. I already checked for the error log file but it doesn't exist in the directory. I also checked /var/log/httpd/error_log but no uploading related problems. I don't know anything else which might have caused the problem so I have reached out for your helping hand. Thanks!

• Extending Eclipse product

  - by zeroin23

  A spawn off of an existing eclipse product is required for customization for a client. (hence parallel product development) The intention was to use Eclipse Fragment, but "Fragments are additive, they cannot override content found in the host." how can we maintain one set of codes in the svn, yet allow customization by overriding some classes?

• Finding all CLASSPATH resources matching a pattern

  - by binil

  I want to read a bunch of text files, by loading them as resources using the context classloader. URL url = Thread.currentThread() .getContextClassloader() .getResource("folder/foo.txt"); Is there some way to get a list of resources whose names match a given pattern? For eg: URL[] matchingUrls = someLibrary.getMatchingResources("folder/*.txt"); Libraries like Spring can scan the classpath to find classes with a given annotation, so I am wondering if there something similar to load a bunch of resources.

• Design question: Should the client both create the session and the socket?

  - by the_drow

  I have three classes: Client Session Socket Both Session & Socket depeand on the Client to create both objects. A Session depeands on a Socket and no sockets are created without a session. Should the Client have a function that creates a Session pubically and a Socket privately? Doesn't it violate the law of demeter?

• Any cloud storage service that lets us to authenticate the file when we serve the file to our visito

  - by TORr0t

  Lets say, i want to restrict a file to my visitors. I mean , i have an xx.avi file to be streamed/downloaded, and the visitor paid me for the bandwidth and the size of the file. In amazon s3, i cant control the file at all .(there is a very basic control thing which is not ok for me) Only way is my server can proxy the file, like it fetches the file from amazon s3 storagenode and send it to the owner with authentication approval by a php script. But this way i would double up the bandwidth usage and again there would be latency problem since my server needs to get the file from amazon s3. So i was wondering if there is a better solution or any cloud storage service that lets us to control the file restriction to my visitors. Thanks

• Get main article image with PHP

  - by PaulAdamDavis

  Hello! I'd like to get the main image for an article, much like Facebook does when you post a link (but without the choosing image part). The data we have to work with is the whole pages HTML as a variable. The page & URL will be different for every time this function runs. Are there any libraries or classes that are particularly good at getting the main body of content, much like Instapaper that would be of any help?

• Is there a tool to generate MVC code in C#?

  - by Rity

  I was working on a project with a colleague and went out for lunch one day. Given that we only spent a few days doing design and no coding, I was surprised to find out that after lunch, he had over 40 files completed (various classes, interfaces, DTOs, etc). He told me he is just a fast typist but I need to know the real deal. He hasn't been able to sustain that kind of productivity just the initial skeletal code but still, any ideas how he did this?
