  • Why do I get corrupt output on my file?

    - by Martin
    I have a simple program which I have compiled in both MinGW and Visual C++ 2008 Express, and both give an output file larger than 88200. When I set s = 0, both programs work as expected. What am I doing wrong? #include <fstream> using namespace std; int main(int argc, char *argv[]) { int i; short s; fstream f; f.open("test.raw", ios_base::out); for(i = 0; i < 44100; i++) { s = i & 0xFFFF; // PROBLEM? f.write(reinterpret_cast<const char *>(&s), sizeof(s)); } f.close(); return 0; }

  • How to Iterate a Resharper Template ?.

    - by sree
    I have a small Resharper Template I have written for Null check of a function Parameter (C#). Check.IsNotNull($param$, "$param$"); - Suggest Parameter - #1 I can now null check the function paramters one by one. But I want to be able to null check all the paramters at once through a template. Is it Possible in Resharper?. Is there someting like a "$Foreach" using which I can loop through parameter variables and write the code to check them one by one ?. (without writing out the foreach into the code) I see that the "Alt + Ins" does something similar. (Taking all Properties on the class and making them as parameters of a constructor). So hoping that there's a way out.

  • Dynamically load a type from an external assembly

    - by Water Cooler v2
    From managed code, how do I load a managed type from another assembly at runtime, assuming the calling code does not have a static reference to the assembly? To clarify, let's say I have class Lib in Lib.cs compiled into Lib.dll. I want to write a class Foo in a separate assembly called Foo.dll, that does not have a reference to Lib.dll statically, but instead loads Lib.dll and then reflects on for the presence of the class Lib and then calls a method on it. Sorry for such an obvious question on Reflection. I figure it'll take much lesser time to get the answer on a forum that to read a few articles.

  • Managed C++ prospects

    - by Srikanth
    Has anyone tried coding in managed C++? I have a few questions : How productive is the language compared to C#? Is there any restriction on type of projects that can be written? Can we write a web application in managed C++? Is it possible to mix managed and unmanaged C++ code in one application? Is MFC still valid in managed C++? Will it be the best option when considering migration of a VC++ application?

  • how to diff / align Python lists using arbitrary matching function?

    - by James Tauber
    I'd like to align two lists in a similar way to what difflib.Differ would do except I want to be able to define a match function for comparing items, not just use string equality, and preferably a match function that can return a number between 0.0 and 1.0, not just a boolean. So, for example, say I had the two lists: L1 = [('A', 1), ('B', 3), ('C', 7)] L2 = ['A', 'b', 'C'] and I want to be able to write a match function like this: def match(item1, item2): if item1[0] == item2: return 1.0 elif item1[0].lower() == item2.lower(): return 0.5 else: return 0 and then do: d = Differ(match_func=match) d.compare(L1, L2) and have it diff using the match function. Like difflib, I'd rather the algorithm gave more intuitive Ratcliff-Obershelp type results rather than a purely minimal Levenshtein distance.

  • Serialization java to c#

    - by tom
    Hi, I have manged to serialize an arraylist in java using xstream, send it to my c# application via http and then write that to file (just for now). The serialized data was an arraylist in java. I want to try and re form this arraylist in c# from the xml i have. I have been looking at http://code.google.com/p/xstream-dot-net/ to do this. Does anyone know if that is the right way to go or is there a better way of reforming the serialized data in c#?

  • Surface Area of a Spheroid in Python

    - by user3678321
    I'm trying to write a function that calculates the surface area of a prolate or oblate spheroid. Here's a link to where I got the formulas (http://en.wikipedia.org/wiki/Prolate_spheroid & http://en.wikipedia.org/wiki/Oblate_spheroid). I think I've written them wrong, but here is my code so far; from math import pi, sqrt, asin, degrees, tanh def checkio(height, width): height = float(height) width = float(width) lst = [] if height == width: r = 0.5 * width surface_area = 4 * pi * r**2 surface_area = round(surface_area, 2) lst.append(surface_area) elif height > width: #If spheroid is prolate a = 0.5 * width b = 0.5 * height e = 1 - a / b surface_area = 2 * pi * a**2 * (1 + b / a * e * degrees(asin**-1(e))) surface_area = round(surface_area, 2) lst.append(surface_area) elif height < width: #If spheroid is oblate a = 0.5 * height b = 0.5 * width e = 1 - b / a surface_area = 2 * pi * a**2 * (1 + 1 - e**2 / e * tanh**-1(e)) surface_area = round(surface_area, 2) lst.append(surface_area, 2) return lst

  • Math Mod Containing Numbers

    - by TheDarkIn1978
    i would like to write a simple line of code, without resorting to if statements, that would evaluate whether a number is within a certain range. i can evaluate from 0 - Max by using the modulus. 30 % 90 = 30 //great however, if the test number is greater than the maximum, using modulus will simply start it at 0 for the remaining, where as i would like to limit it to the maximum if it's past the maximum 94 % 90 = 4 //i would like answer to be 90 it becomes even more complicated, to me anyway, if i introduce a minimum for the range. for example: minimum = 10 maximum = 90 therefore, any number i evaluate should be either within range, or the minimum value if it's below range and the maximum value if it's above range -76 should be 10 2 should be 10 30 should be 30 89 should be 89 98 should be 90 23553 should be 90 is it possible to evaluate this with one line of code without using if statements?

  • How do I run an XSLT file?

    - by Eric
    Alright this seems like a stupid question but I can't figure it out. I'm writing an XSLT file to translate an XML document into an XHTML document. I've used both Visual Studio and XML Notepad 2007 to preview the results of my XSLT file, but now I want to actually write out a real XHTML file so I can see how it looks in other browsers. Neither Visual Studio or XML NotePad have an obvious way to save the preview. Am I missing something. Obviously the file is getting created because something is being previewed, but I need to know where that file is being created or better yet choose its location.

  • Fastest way to convert file from latin1 to utf-8 in python.

    - by xsaero00
    I need fastest way to convert files from latin1 to utf-8 in python. The files are large ~ 2G. ( I am moving DB data ). So far I have import codecs infile = codecs.open(tmpfile, 'r', encoding='latin1') outfile = codecs.open(tmpfile1, 'w', encoding='utf-8') for line in infile: outfile.write(line) infile.close() outfile.close() but it is still slow. The conversion takes one fourth of the whole migration time. I could also use a linux command line utility if it is faster than native python code.

  • How to document a Symfony based REST API (similar to enunciate's documentation capabilities)

    - by Dominic
    If I have a REST based service written in the Symfony [symfony-project.org] framework (i.e. PHP), is there any decent tools/frameworks out there that will parse my code and generate API documentation? The Java based framework enunciate has documentation capabilities similar to what I need, you can view an example of this here: http://enunciate.codehaus.org/wannabecool/step1/index.html. I understand the premise of REST based services are supposed to be self evident, however I was after something that would generate this documentation for me without the need to manually write up all my endpoints, supported formats, sample output etc. Thanks

  • Rails test across multiple environments

    - by DSimon
    Is there some way to change Rails environments mid-way through a test? Or, alternately, what would be the right way to set up a test suite that can start up Rails in one environment, run the first half of my test in it, then restart Rails in another environment to finish the test? The two environments have separate databases. Some necessary context: I'm writing a Rails plugin that allows multiple installations of a Rails app to communicate with each other with user assistance, so that a user without Internet access can still use the app. They'll run a local version of an app, and upload their work to the online app by saving a file to a thumbdrive and taking it to an Internet cafe. The plugin adds two special environments to Rails: "offline-production" and "offline-test". I want to write functional tests that involve both the "test" and "offline-test" environments, to represent the main online version of the app and the local offline version of the app respectively.

  • How to Not alter font in webpage after opening a file (pdf or jpg) in ASP.NET C#? [closed]

    - by Victor
    Possible Duplicate: How to not alter font in webpage after opening a pdf in ASP.NET C#? Previously I posted this question: How to open files from a specific route in ASP-NET c#? in fact, I have already asked this however it was only a minor question so I guess it wasn't that important in the previous post, so I will ask here. Whenever I open a pdf with: Response.Write("<script>window.open('FilePath');</script>"); All of the font in the page is altered, example, the letter's size increases and some of the letter's colors are switched to black instead of the font that I assigned. Is there a way that I can work around that?? http://imageshack.us/a/img838/5145/beforeja.png http://imageshack.us/a/img546/4760/afterw.png Oh and I noticed that this also happens when you open images like jpg

  • Best Java library(ies) for forgiving command interpreter

    - by vkraemer
    I am looking for a library or set of libraries that will help me write a forgiving command interpreter. A forgiving command interpreter would be a command interpreter which can deal with simple and even not so simple spelling and word order mistakes in the input. My goal is to have an interpreter which would take the input (a command) from a user and then: execute the command, if it is correct. apply corrections to the command, until a correct command is generated and then present that command to the user to confirm whether it is 'what the user meant'.

  • Best ways to reuse Java methods

    - by carillonator
    I'm learning Java and OOP, and have been doing the problems at Project Euler for practice (awesome site btw). I find myself doing many of the same things over and over, like: checking if an integer is prime/generating primes generating the Fibonacci series checking if a number is a palindrome What is the best way to store and call these methods? Should I write a utility class and then import it? If so, do I import a .class file or the .java source? I'm working from a plain text editor and the Mac terminal. Thanks!

  • How do I hook all http get requests and distinguish downloaded (by standard download manager) files

    - by Ivan
    I want to write a Firefox add-on for advanced history tracking and bookmarking which will send URLs the browser meets during usage (and all the metadata available about the context) to a web service which will keep track of them storing in an SQL database for further access and analysis. I'd like to divide URLs tracked into 5 groups: those I explicitly click to bookmark, those I download by Firefox standard built-in download manager, all other URLs accessed, all URLs met on all viewed pages as hrefs, all other URLs mentioned in HTML sources of all viewed pages. Any ideas of how to get those in an extension?

  • Accented character regex

    - by user314573
    I'm trying to create a regex that will look for french words whether a user specifies the accented characters or not. So if the the user has searched for "déclaré" but types in declare instead I would like to be able to match the text still. I'm having difficulty making this more dynamic so that it can be matched on any french word... Closest example from another user from a different post was: d[eèéê]cl[aàáâ]r[eèéê] Is it even possible to write a regex for something like this? Any advice would be much appreciated.

  • JavaScript: function returning NAN

    - by Michael
    I'm working on a codecademy.com lesson with instructions to write the calculateTotal function below. When I click run, it's returning NaN. Anyone know what's wrong with the calculateTotal function as I wrote it that's making it return NaN. Note, I understand that NaN means not a number... // runner times var carlos = [9.6,10.6,11.2,10.3,11.5]; var liu = [10.6,11.2,9.4,12.3,10.1]; var timothy = [12.2,11.8,12.5,10.9,11.1]; // declare your function calculateTotal here var calculateTotal = function(raceTimes){ var totalTime; for(i = 0; i < raceTimes.length; i++){ totalTime += raceTimes[i]; return totalTime; } }; var liuTotal = calculateTotal(liu); console.log(liuTotal);

  • Is it possible to optimize maven dependencies automatically?

    - by AlexR
    I am working on a big project that consists of about 40 sub-projects with very not optimized dependencies. There are declared dependencies that are not in use as well as used but undeclared dependencies. The second case is possible when dependency is added via other dependency. I want to remove redundant and add required dependencies. I ran mvn dependency:analyze and got a long list of warnings I have to fix now. I wonder whether there is maven plugin or any other utility that can update my pom.xml files automatically. I tried to do it manually but it takes a lot of time. It seems it will take a couple of days of copy/paste to complete the task. In worse case I can write such script myself but probably ready stuff exists? Here is how mvn dependency:analyze reports dependency warnings: [WARNING] Used undeclared dependencies found: [WARNING] org.apache.httpcomponents:httpcore:jar:4.1:compile [WARNING] Unused declared dependencies found: [WARNING] commons-lang:commons-lang:jar:2.4:compile [WARNING] org.json:json:jar:20090211:compile

  • VBA SQL Loop using QODBC

    - by Dan
    I am trying to loop through an existing table (tblSalesOrder) and I need to run through every line (where they relate to that particular customer) and write each line into an SQL statement and execute it. What is the easiest way to go about this procedure? The number of lines will need to be counted prior to data being written via SQL to a QuickBooks database. I can code something similar in php using the code below, but I am unsure how to convert this into a VBA friendly format: $sql_count = "SELECT count(*) FROM tblSalesOrder WHERE Customer='cust_number'"; execute_query($sql_count) When the above value is greater than 0, the vba code should loop through the queries. Thanks everyone

  • How to embed a web browser control in a cross-platform application?

    - by Gil
    hi, I need to write quickly this application: a simple window that wraps a web browser control, that runs html pages. The Browser UI (e.g. Navigation buttons) should be suppressed. As a .net developer, I would embed the WebBrowser OCX in a Windows Form. But this has to run on Mac as well!! I found the following cross-platform candidates. Which one would you choose (in terms of simplicity, stableness, community support, etc.): 1) wxWidgets (www.kirix.com/labs/wxwebconnect.html) 2) QT: www.youtube.com/watch?v=Ee8eRwjbcFk&feature=related 3) MONO: www.mono-project.com/WebBrowser Thanks!

  • Make C# source run as a script?

    - by acidzombie24
    I am doing a little scripting and i find some more power would be nice. Like the ability to keep trying to delete a file with a 1sec delay AND have it portable since i spent some time today translating a bat script to bash. I know i can use php or python but i VERY MUCH PREFER static/compile time checking. Is there a way to run C# code as a script? I am hoping i dont have to create a custom ext and write a app to dynamically compile and execute the script (i know have source to compile .js somewhere...). Does anyone know of a solution?
