  • Accessing C++ methods from Csharp

    - by Code Smack
    Hello, I have a string with CompressedRichText in it. I want to uncompressed it to standard RTF and then to plain Text. I am using VS 2008 C# Windows Application. I found references to C++ code to do it, but nothing directly in C#. I found some info at this site on the C++ part, but I have no idea how to use this from my C# code. What do I need to do in order to access the methods in the C++ code from my C# project. Link to the C++ Code http://msdn.microsoft.com/en-us/library/bb905295.aspx Thanks!

  • Converting Source ASCII Files to JPEGs

    - by CommonsWare
    I publish technical books, in print, PDF, and Kindle/MOBI, with EPUB on the way. The Kindle does not support monospace fonts, which are kinda useful for source code listings. The only way to do monospace fonts is to convert the text (Java source, HTML, XML, etc.) into JPEG images. More specifically, due to pagination issues, a given input ASCII file needs to be split into slices of ~6 lines each, with each slice turned into a JPEG, so listings can span a screen. This is a royal pain. My current mechanism to do that involves: Running expand to set a consistent 2-space tab size, which pipes to... a2ps, which pipes to... A small Perl snippet to add a "%%LanguageLevel: 3\n" line, which pipes to... ImageMagick's convert, to take the (E)PS and make a JPEG out it, with an appropriate background, cropped to 575x148+5+28, etc. That used to work 100% of the time. It now works 95% of the time. The rest of the time, I get convert: geometry does not contain image errors, which I cannot seem to get rid of, in part because I don't understand what the problem is. Before this process, I used to use a pretty-print engine (source-highlight) to get HTML out of the source code...but then the only thing I could find to convert the HTML into JPEGs was to automate screen-grabs from an embedded Gecko engine. Reliability stank, which is why I switched to my current mechanism. So, if you were you, and you needed to turn source listings into JPEG images, in an automated fashion, how would you do it? Bonus points if it offers some sort of pretty-print process (e.g., bolded keywords)! Or, if you know what typically causes convert: geometry does not contain image, that might help. My current process is ugly, but if I could get it back to 100% reliability, that'd be just fine for now. Thanks in advance!

  • Use a cat + grep as an included source in bash

    - by Andrew
    I'm on a shared webhost where I don't have permission to edit the global bash configuration file at /ect/bashrc. Unfortunately there is one line in the global file, mesg y, which puts the terminal in tty mode and makes scp and similar commands unavailable. My local ~./bashrc includes the global file as a source, like so: # Source global definitions if [ -f /etc/bashrc ]; then . /etc/bashrc fi My current workaround uses cat and grep to output the global file, sans offending line, into a local file and use that as a source. # Source global definitions if [ -f /etc/bashrc ]; then cat /etc/bashrc | grep -v mesg > ~/.bash_global . ~/.bash_global fi Is there a way to do include a grokked file like this without the intermediate step of creating an actual file? Something like this? . cat /etc/bashrc | grep -v mesg > ~/.bash_global

  • I want to compile a batch file into an exe using c++, i can get through parsing the batch file and w

    - by Nareshkumar Rao
    Ok, here's the thing, I am creating an application in DevC++ that will read in a batch file. then, one by one parsing it using: system(getline(myfile,line)); After setting everything up, I save the newly created file as "main.cpp". The problem is, I want to compile it into an exe, from my program, for the end user. So basically, I'm asking whether I can compile a C++ file from a C++ Exe..

  • Can you call compiled JRuby classes from java?

    - by John Baker
    So I came up with the general idea to write some code in JRuby, then access all the classes via Java. I have no idea if this is at all possible but I wanted to ask anyway. Lets say I have some JRuby code: class adder def addme return 22 end end If I compiled this with jrubyc is there any way I could then possibly do something like this in java: import adder; class anything { void testMethod() { adder a = new adder(); int x = a.addme(); } } After looking at it now it sort of makes me think that Java will have zero idea what sort of item test addme is going to return so that might not work. I don't know but I wanted to throw it out there anyway. Thanks

  • Need help to understand :source option of has_one/has_many through of Rails

    - by Tri Vuong
    Hi Please help me in understanding the :source option of has_one/has_many through association. The Rails api explanation makes very little sense to me "Specifies the source association name used by has_many :through queries. Only use it if the name cannot be inferred from the association. has_many :subscribers, :through = :subscriptions will look for either :subscribers or :subscriber on Subscription, unless a :source is given. " Thanks.

  • Closed Source Java Applications

    - by Paul
    I am taking programming courses and we have been discussing Open Source and having a bit of an argument over the confusion. Just because Java is Open Source, the licensing on developed applications starts at the developer, correct? Someone is arguing about the use of code from a complete program just because "Java is Open Source". If I write a Java application, what are the limitations on how I can distribute it or how someone else can use it? Assume here that I DO NOT want someone having access to my source. Thanks

  • C# properties: How are they instantiated?

    - by Pedery
    Hi! This might be a pretty straightforward question, but I'm trying to understand some of the internal workings of the compilation. Very simply put, imagine an arbitrary object being instantiated. This object is then allocated on the heap. The object has a property of type PointF (which is value type), with a get and a set method. Imagine the get and the set method containing a few calculations for doing their work. How and where (stack/heap) and when is this code instantiated? This is the background for this question: I'm writing get and set methods for an object and these methods need to be accessed very frequently. The get and set code in itself is rather massive so I feared that in a worst case scenario the methods would be instantiated as an object or a value type with all internal code for every access of the property. On the other hand the code is probably instantiated when the main object is created and the CPU is simply told to jmp to the property code start. Anyway, this is what I want to have clarified.

  • Replace <Unknown Source> in Java Rhino (JSR223) with actual file name

    - by Lord.Quackstar
    Hello everyone, In my code, all of the scripts are contained in .js files. Whenever one of the scripts contains an error, I get this: javax.script.ScriptException: sun.org.mozilla.javascript.internal.EcmaError: ReferenceError: "nonexistant" is not defined. (<Unknown source>#5) in <Unknown source> at line number 5 What bugs me is the <Unknown Source>. Multiple files are in one ScriptContext, and it can be hard to track down an error. It also looks horrible. Is there a way to replace <Unknown Source> with the actual file name? None of the methods I see support passing a File object, so I'm really confused here.

  • Why does C++ linking use virtually no CPU? (updated)

    - by John
    On a native C++ project, linking right now can take a minute or two, yet during this time CPU drops from 100% during compilation to virtually zero. Does this mean linking is primarily a disk activity? If so, is this the main area an SSD would make big changes? But, why aren't all my OBJ files (or as many as possible) kept in RAM after compilation to avoid this? With 4Gb of RAM I should be able to save a lot of disk access and make it CPU-bound again, no? update: so the obvious follow-up is, can VC++ compiler and linker talk together better to streamline things and keep OBJ files in memory, similar to how Delphi does?

  • StackOverflow Error at java.util.AbstractColllection.<init>(Unknown Source)

    - by thebulge
    I fixed my prior problem yesterday by just separating all the classes into separate files. Nevertheless, I wrote all the code down and seeing no errors was able to compile the program. Or so I thought. Here's the error code: Exception in thread "main" java.lang.StackOverflowError at java.util.AbstractCollection.<init>(Unknown Source) at java.util.AbstractList.<init>(Unknown Source) at java.util.Vector.<init>(Unknown Source) at java.util.Vector.<init>(Unknown Source) at java.util.Vector.<init>(Unknown Source Here are the spots where my I get the errors(marked with problem?) public class GameWorld implements IObservable, IGameWorld { // create collections class public Vector<GameObject> GameObjectList = new Vector<GameObject>(); // PROBLEM private Vector<IObserver> ObserverList = new Vector<IObserver>(); // declare objects Tank pTank = new Tank(10, 10); // other objects and variables to declare public GameWorld() { // add objects to GameObjectList } // accessors/mutators } I get another error here public class Tank extends Movable implements ISteerable { private int armorStrength; private int missileCount; public Tank() {} public Tank(int armStr, int misslCt) // problem? { armorStrength = armStr; // default armorStrength missileCount = misslCt; // default missileCount } public void setDirection(int direction) { this.setDirection(direction); // get input from left turn or right turn // updateValues(); } // access/mutators here I'm stumped on what to do here.

  • Navigate HTML Source while performing WatiN tests

    - by youwhut
    I am performing actions on the page during WatiN tests. What is the neatest method for asserting certain elements are where they should be by evaluating the HTML source? I am scraping the source but looking for a clean way to navigate the tags pulled back. UPDATE: Right now I am thinking about grabbing certain elements within HTML source using regular expressions and then analysing that to see if other elements exist within. Other thoughts appreciated.

  • If I write a framework that gets information from the Internet, should I make a degelate or use blocks?

    - by Time Machine
    Say I'm writing a publicly available framework for the Vimeo API. This framework needs to get information from the Internet. Because this can take some time, I need to use threadin to prevent the UI from hanging. Foundation uses delegates for this, like NSURLConnectionDelegate. However, Game Kit uses blocks as callback functions. What is the recommended way of doing this? I know blocks aren't supported in standard GCC versions, but they require less, much less code for the one that uses my framework. Delegates, on the other hand, are real methods and when protocols are used, I'm sure the methods are implemented. Thanks.
