  • How to create proc under /proc/driver?

    - by Mustika_wiguna
    I want to create a proc file under /proc/driver directory. I would like to use a macro like proc_root_driver (or something else provided) rather than use "driver/MODULE_NAME" explicitly. I use create_proc_entry : ... struct proc_dir_entry *simpleproc_fops_entry; simpleproc_fops_entry = create_proc_entry(MODULE_NAME, 0400, NULL /* proc_root_dir */); ... After googling, I found suggestion to use proc_root_driver, but when I use it, error "proc_root_driver undeclared in this function". And also, proc_root_driver is not available in linux/proc_fs.h. I have tried to declare structure like this: struct proc_dir_entry proc_root; struct proc_dir_entry *proc_root_driver = &proc_root; Errors gone, but proc file didn't exist under /proc/driver or /proc Anyone here can help me? Thanks in advances.

  • Using a set of numbers inside a database without creating a temporary table

    - by Zizzencs
    I have a set of numbers and a table in a database with the id (primary key) and text (not null) columns. I would like to create a query that returns all the numbers in the set and the associated text from the table. Unfortunately not all numbers exist in the database's id column, so this won't work: select id, text from table where id in (<set of numbers>) For the non-existing ids the best would be to return null as the text from the query. Is there a way to produce the desired output without first creating a temporary table from the set inside the database? The database engine in use is a Microsoft SQL Server 2008 SP1 but I'd be interested in any solution with any database engine.

  • Compiler #defines for g++ and cl

    - by DHamrick
    I am writing a program that is cross platform. There are a few spots where I have to specify an operating system dependent call. #ifdef WINDOWS ..do windows only stuff #endif #ifdef LINUX ..do linux only stuff #endif Are there any preprocesser directives that get defined by the compiler so I don't have to explicitly define them when I use the command line compiler. ie. cl -DWINDOWS program.cpp or g++ -DLINUX program.cpp I realize I could easily write a makefile or have a shell/batch script that will do this automatically. But I would prefer to use the same ones as the compiler (if they exist) by default.

  • API to lookup product information by UPC?

    - by officespace672
    Is there an API that allows lookup of product information by UPC? I know that Amazon has the Product Advertising API but don't think it can be used for any purpose other than sending traffic to amazon.com as per their license agreement here. Specifically, my application would not have the principal purpose of advertising and marketing the Amazon Site and driving sales of products and services on the Amazon Site Does such an API exist that I can do anything I want with the data? UPDATE I would want to use the API for my application, not create create such an API.

  • Examples of ISO C++ code that is not valid C++/CLI

    - by Johannes Schaub - litb
    I've seen contradictory answers on the internet with regard to whether C++/CLI is a superset of C++ or not. The accepted answer on this question claims that "technically no", but doesn't provide an examples of non-C++/CLI code that conforms to ISO C++. Another answer on that question cites a book that says the opposite. So, can you please provide accurate answers with example code that fails on C++/CLI or cite a trusted source (MSDN for example) on this matter? I had someone this topic come up today and thought I would like to inform myself, but I didn't find any clear answer elsewhere!

  • Javascript Prototype Best Practice Event Handlers

    - by nahum
    Hi this question is more a consulting of best practice, Sometimes when I'm building a complete ajax application I usually add elements dynamically for example. When you'r adding a list of items, I do something like: var template = new Template("<li id='list#{id}'>#{value}</li>"); var arrayTemplate = []; arrayOfItem.each(function(item, index){ arrayTemplate.push(template.evaluate( id : index, value : item)) }); after this two options add the list via "update" or "insert" ----- $("elementToUpdate").update("<ul>" + arrayTemplate.join("") + "</ul">); the question is how can I add the event handler without repeat the process of read the array, this is because if you try add a Event before the update or insert you will get an Error because the element isn't still on the DOM. so what I'm doing by now is after insert or update: arrayOfItem.each(function(item, index){ $("list" + index).observe("click", function(){ alert("I see the world"); }) }); so the question is exist a better way to doing this??????

  • [JS/jQuery] Using argument (this) passed via element eventhandler

    - by Kel
    Hey guys, I want to use the argument I pass (this) in a JS function and treat it as an jQuery variable. Example: <script> function useMe(obj){ $(obj).val(); ... ... ... } </script> <select id="selectid" onChange="useMe(this)"> <option>......</option> </select> Is there a possibility to treat the passed argument as a jQuery element? Btw. I need to do it this way, because the select-element isn't created on load. The select element will be created later asynchronously. So, this won't work: $("select").each(function (i){ var select_id = $(this).attr("id"); $(this).change(function(e){ because it doesn't exist yet. Thanks for your help.

  • How to make one ASP.NET MVC site "derive" from another.

    - by Rob Levine
    My question is similar to "ASP.NET 2 projects to share same files", but with an ASP.NET MVC slant. Basically, we have two sites, one being based mostly on the other (roughly 90% views, controllers, images, in the second are identical to the first). However, in some cases, the views may be different, or a controller in the second site may be different to the first. Are there any simple ways of achieving this in ASP.NET MVC? So far, we've looked at using linked files to have two totally seperate projects where the second project shares the files it needs from the first. One problem with this approach is that most pages in the second project don't literally exist in the virtual directory, it makes debugging a pain - you have to publish in order to generate the files so you can debug. Does anyone have any better approaches, or ways this approach can be simplified?

  • handle exit event of child process

    - by Ehsan
    I have a console application and in the Main method. I start a process like the code below, when process exists, the Exist event of the process is fired but it closed my console application too, I just want to start a process and then in exit event of that process start another process. It is also wired that process output is reflecting in my main console application. Process newCrawler = new Process(); newCrawler.StartInfo = new ProcessStartInfo(); newCrawler.StartInfo.FileName = configSection.CrawlerPath; newCrawler.EnableRaisingEvents = true; newCrawler.Exited += new EventHandler(newCrawler_Exited); newCrawler.StartInfo.Arguments = "someArg"; newCrawler.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; newCrawler.StartInfo.UseShellExecute = false; newCrawler.Start();

  • Database indexes and their Big-O notation

    - by miket2e
    I'm trying to understand the performance of database indexes in terms of Big-O notation. Without knowing much about it, I would guess that: Querying on a primary key or unique index will give you a O(1) lookup time. Querying on a non-unique index will also give a O(1) time, albeit maybe the '1' is slower than for the unique index (?) Querying on a column without an index will give a O(N) lookup time (full table scan). Is this generally correct ? Will querying on a primary key ever give worse performance than O(1) ? My specific concern is for SQLite, but I'd be interested in knowing to what extent this varies between different databases too.

  • Should we use a CSS frame work ? Are they worth it ?

    - by Gaurav M
    CSS frameworks have nice styles inbuilt and ask you to focuses on the grids but still there is a bit of dependency and lack of freedom it provide.. If I need to generate a webpage by looking on a PSD based mockup screen ..either i will use the classes provided by the framework but if that actual measurements does not exist I need to again specify my own rules that will add upto my CSS filesize and if performance is a constraint as always it is...you need not a big size file..though its in kb but every drop counts. Any comments and suggestions to use the framework in a best possible way.

  • Php/ODBC encoding problem

    - by JohnM2
    I use ODBC to connect to SQL Server from PHP. In PHP I read some string (nvarchar column) data from SQL Server and then want to insert it to mysql database. When I try to insert such value to mysql database table I get this mysql error: Incorrect string value: '\xB3\xB9ow...' for column 'name' at row 1 For string with all ASCII characters everything is fine, the problem occurs when non-ASCII characters (from some European languages) exist. So, in more general terms: there is a Unicode string in MS SQL Server database, which is retrieved by PHP trough ODBC. Then it is put in sql insert query (as value for utf-8 varchar column) which is executed for mysql database. Can someone explain to me what is happening in this situation in terms of encoding? At which step what character encoding convertions may take place? I use: PHP 5.2.5, MySQL5.0.45-community-nt, MS Sql Server 2005.

  • NetBeans Platform Unit Test Library Dependencies

    - by Ben Hammond
    I am working on a Netbeans Platform RCP application. I use jmock in my unit tests and I have created a Library Wrapper Module to import the necessary libraries. The Module has an section named 'Libraries' and another section named 'Unit Test Libraries'. I hoped that I could add the JMock Library Wrapper to the 'Unit Test Libraries', however when I run the unit tests I get the error 'package org.jmock does not exist'. If I import the JMock Library Wrapper in to the main 'Libraries' element then it works, but this feels wrong. Maven allows me to specify unit-test only dependencies, and I assumed that NetBeans Platform did the same. Should this be possible? Am I doing something wrong? Should I resign myself to a run-time dependency on the unit-test libraries (ugh).

  • Practical Python-based visual programming environment?

    - by Who8MyLunch
    I am looking for a practical visual programming environment based on Python. My primary application is algorithm development for processing remote-sensing imagery. I was initially inspired by LabVIEW from National Instruments, but that is more geared towards laboratory measurements and simulations. I write a lot of prototype code in Python and do a lot of interactive analysis with IPython. Does there exist a visual framework where a "program" is represented by connected nodes which each read data, do some work, and output data to the next node? I would like to use Python to write the code residing in each node. So far the best I've seen is Orange http://www.ailab.si/orange/, but it does not have the ability to start/stop individual nodes.

  • What benefits can Java developer have moving to a *NIX platform?

    - by dave-keiture
    Hi everyone, A friend of mine is a Java developer, who's using *NIX for ages. He claims that *NIX is for real Java geeks, whereas WIN is for dummies (and I'm one of them, according to him) and girls. When I ask him to argue his position, and explain, what's so good for Java developer on *NIX, he starts talking about console, wget, curl and grep. But sorry, wget and curl analogues exist for the WIN platform as well. As for the console - I'm using FAR Commander, and have access to the command line when I need. Moreover, even if I decide moving to *NIX, I will certainly use Netbeans or Eclipse there, so there will be no big difference. Guys, who use Java on *NIX, could you please give me a real killer examples, when *NIX (any util or technique) dramatically increases Java development productivity (in the way the hints are given in "The Pragmatic Programmer"), or, which is also important, gives more fun from the process. Thanks in advance!

  • PHP is_file returns false (incorrectly) for Windows share on Ubuntu

    - by M3Mania
    Ubuntu server, PHP 5.3, connected via Samba to Windows server share. I am using file_exists() to check for availability of file on Windows machine. It returns false, although the filepath does exist. Meanwhile, file_get_contents() on the exact same filepath works fine. I'm wondering if it's a permission issue, since I'm having trouble configuring permissions of the files on the Windows share (it says I don't have permission to change permissions on them). When I look at the permissions through Nautilus, it says the user and group are both root, with 755 rights. I'd like to change the group to www-data, but can't seem to do it.

  • Sqlite. How to create an index in attached DB?

    - by kappa
    I have a problem with adding index to memory database attached to main database. 1) I open the database (F) from file 2) Attach the :memory: (M) database 3) Create tables in database M 4) Copy data from F to M I would also like to create an index in database M, but don't know how to do that. This code creates index but in F database: sQuery = "CREATE INDEX IF NOT EXISTS [INDID] ON [PANEL]([ID] ASC);"; I tried to add the name qualifier before table name like this: sQuery = "CREATE INDEX IF NOT EXISTS [INDID] ON [M.PANEL]([ID] ASC);"; but SQLite returns with message that column main.M.PANEL does not exist. What can I do?

  • Pros and cons of Localisation of technical words ?

    - by paercebal
    This question is directed to the non-english speaking people here. It is somewhat biased because SO is an "english-speaking" web forum, so... In the other hand, most developers would know english anyway... In your locale culture, are technical words translated into locale words ? For example, how "Design Pattern", or "Factory", or whatever are written/said in german, spanish, etc. etc. when used by IT? Are the english words prefered? The local translation? Do the two version (english/locale) are evenly used? Edit Could you write with your answer the locale translation of "Design Pattern"? In french, according to Wikipedia.fr, it is "Patron de conception", which translates back as "Model of Conceptualization" (I guess).

  • Check if row already exists, if so tell the referenced table the id

    - by flhe
    Let's assume I have a table magazine: CREATE TABLE magazine ( magazine_id integer NOT NULL DEFAULT nextval(('public.magazine_magazine_id_seq'::text)::regclass), longname character varying(1000), shortname character varying(200), issn character varying(9), CONSTRAINT pk_magazine PRIMARY KEY (magazine_id) ); And another table issue: CREATE TABLE issue ( issue_id integer NOT NULL DEFAULT nextval(('public.issue_issue_id_seq'::text)::regclass), number integer, year integer, volume integer, fk_magazine_id integer, CONSTRAINT pk_issue PRIMARY KEY (issue_id), CONSTRAINT fk_magazine_id FOREIGN KEY (fk_magazine_id) REFERENCES magazine (magazine_id) MATCH SIMPLE ON UPDATE NO ACTION ON DELETE NO ACTION ); Current INSERTS: INSERT INTO magazine (longname,shotname,issn) VALUES ('a long name','ee','1111-2222'); INSERT INTO issue (fk_magazine_id,number,year,volume) VALUES (currval('magazine_magazine_id_seq'),'8','1982','6'); Now a row should only be inserted into 'magazine', if it does not already exist. However if it exists, the table 'issue' needs to get the 'magazine_id' of the row that already exists in order to establish the reference. How can i do this? Thx in advance!

  • Good open source analytics/stats software in PHP?

    - by makeee
    The url shortening service I'm building needs to display some basic click stats to users: # of clicks, conversions, referring domains, and country (filterable by a date range). I'll possibly want more advanced stats in the future. Is there existing open source software that will allow me to pass events to it and then easily display a bar or line graph of that event (for example, a line graph of "conversions" between two specified dates). It seems like something like this should exist and would be much easier then building the whole thing from scratch. I know there are graphing scripts, but that still requires me to format the data (usually as an xml file) and then pass it to the graph. I'm looking for something a bit more complete, which I can just feed the events and then it does everything else.

  • OAuth 2.0: Can a user-agent client avoid forwarding fragments?

    - by Bosh
    In the OAuth 2.0 draft specification, user-agent clients receive authorization in the form of a bearer token via redirection (from an authentication server) to a URL such as HTTP/1.1 302 Found Location: http://example.com/rd#access_token=FJQbwq9&expires_in=3600 According to Section 3.5.2 it is then the user-agent's job to GET the URL in question, but "The user-agent SHALL NOT include the fragment component with the request." In other words, as a result of the example redirection above, the user-agent should GET /rd HTTP/1.1 Host: example.com without passing #access_token to the server. My question: what user agents behave this way? I thought redirection in Firefox, for example, would (logically) include the fragment in the GET request. Am I just wrong about this, or does the OAuth 2.0 specification rely on non-standard user-agent behavior?

  • Is is possible to make a shaped, alpha-blended dialog?

    - by jgaa
    I'm making a non-rectangular dialog, modelled over an image from Photoshop (the image is the background of the dialog, and the user will see trough the transparent part of the image). I'ts like a dashboard-style window for a media-app with a few custom-drawn controls. Most of the background-image is either opaque or 100% transparent - but in between there is a thin area of partially transparent pixels, ment to blend the image smootly into the background. This works great for web-graphics, but I have not found a way to make this work for Windows windows. I'm using the Windows Template Library (WTL), msvc 2008 - and the app must run on Windows XP as well as Vista and Windows 7. Currently, I'm simply using the opaque part of the background-image to create a GDI clipping-region, but this gives pretty rough edges. Does anyone know about any API functions to accomplish this (part of WTL, or reachable from WTL)?

  • Where should document-related actions for a Cocoa app be implemented?

    - by Adam Preble
    I'm writing a document-based Cocoa app that's basically a graphical editing program. I want the user to be able to show/hide non-modal windows (such as an inspector window). Since these windows would be shown/hidden from menu items, where is the "best" place to implement the actions, such as - (IBAction)toggleInspector:(id)sender? I've seen that in the Sketch example code these are implemented in the app delegate, and the window controller instances are kept there as well, but that feels like more of a convenient place to put it than the most "graceful" place. Additionally, since this inspector would only be relevant when a document is open it feels like it should be associated more with the document's main NSWindowController than the app.

  • C++ Urban Myths

    - by Neil Butterworth
    I'm starting to write an article on what I'm calling "C++ Urban Myths" - that is, ideas and conceptions about C++ that are common but have no actual roots in reality. Some that I've come up with so far are: TR1 is part of standard C++ TR1 (technical Report #1) proposed a whole bunch of changes to C++. Unfortunately, it was never accepted. It is faster to use iterators to access a vector than operator[] Or vice versa. All tests I've carried out indicate the two are nearly identical in performance. The C++ Standard contains something called the STL It doesn't - neither "STL" nor "Standard Template Library" appear in the Standard. I'm wondering if the SO C++ community can come up with any better ones? Ideally, they should be expressible in a single sentence, and not involve any code. Edit: I guess I didn't make it clear enough that I was interested in myths believed by C++ developers, not misconceptions held by non-C++users. Oh well...
