  • algorithmes with no executable example code

    - by gcc
    [link] http://stackoverflow.com/questions/2932016/parsing-of-mathematical-expressions (problem has been told before) ** program is to create the infix tree for the given math expression.** if the expression is given completely paranthesized then the out put is fine but when there are no paranthesis or some part paranthesized then the out put is wrong. cant get the idea how to solve. my problem is told above. I have some algorithm to solve my problem, but I have no simple code which will be guide for me. Can anyone give me simple code (not working code) so that I will try working to understand.(for a 3 hours ,I have been searching and reading some text to understand algorithm which is told above.Actually,there is no example code investigating how it is working. Can anyone send me example which is written in c not other language.

  • Are there any context-sensitive code search tools?

    - by Vicky
    I have been getting very frustrated recently in dealing with a massive bulk of legacy code which I am trying to get familiar with. Say I try to search for a particular function call, I get loads of results that turn out to be completely irrelevant; some of them are easy to spot, eg a comment saying // Fixed functionality in foo() so don't need to handle this here any more But others are much harder to spot manually, because they turn out to be calls from other functions in modules that are only compiled in certain cases, or are part of a much larger block of code that is #if 0'd out in its entirety. What I'd like would be a search tool that would allow me to search for a term and give me the choice to include or exclude commented out or #if 0'd out code. Then the search results would be displayed alongside a list of #defines that are required in order for that snippet of code to be relevant. I'm working in C / C++, but other than the specific comment syntax I guess the techniques should be more generally applicable. Does such a tool exist?

  • How to deploy a Scala project from Eclipse?

    - by lach
    I have a Scala project in Eclipse that I need to package up so I can deploy it to a server. It's based on Jetty but it runs as a standalone application. It contains Scala classes, Java classes and a number of 3rd party jars. I assumed there would be some kind of deployment option in the Scala Eclipse plugin but I've drawn a blank. What is the simplest way to package the Scala project into a runnable file so it can be deployed? Any help greatly appreciated. Cheers.

  • Location of code when sending HTML Email

    - by ChrisWesAllen
    I'm trying to figure out where to put some code in an email. You know how you can get newsletters with styling and images, etc? I wanted to send some out but I cant figure out where to put the code. Do you add the images as attachments? Do you put the code in the body? or should you upload the .html file as well?

  • What did you develop using a microcontroller?

    - by DR
    I've always been fascinated by microcontrollers and I'm planning to do a few hobby projects just to satisfy my inner geek :) I'm looking for ideas and motivation, so what did you develop using a microcontroller? If possible please state the microcontroller and/or development environment and an estimate on hardware costs beyond the basic equipment (if applicable). I'm interested in both successful and failed projects and any problems you encountered.

  • Programmatically parse and edit C++ Source Files

    - by Kryten
    Hi, I want to able programmatically parse and edit C++ source files. I need to be able to change/add code in certain sections of code (i.e. in functions, class blocks, etc). I would also (preferably) be able to get comments as well. Part of what I want to do can be explained by the following piece of code: CPlusPlusSourceParser cp = new CPlusPlusSourceParser(“x.cpp”); // Create C++ Source Parser Object CPlusPlusSourceFunction[] funcs = cp.getFunctions(); // Get all the functions for (int i = 0; i &lt funcs.length; i++) { // Loop through all functions funcs[i].append(/* … code I want to append …*/); // Append some code to function } cp.save(); // Save new source cp.close(); // Close file How can I do that? I’d like to be able to do this preferably in Java, C++, Perl, Python or C#. However, I am open to other language API’s.

  • Generating code at compile-time using scripts

    - by Manux
    Hello, I would ideally like to be able to add (very repetitive) C/C++ code to my actual code, but at compile time, code which would come from say, the stdout of a python script, the same way one does with macros. For example, let's say I want to have functions that depend on the public attributes of a given class, being able to just write the following in my C++ code would be a blessing: generate_boring_functions(FooBarClass,"FooBarClass.cpp") Is that feasible using conventional means? Or must I hack with Makefiles and temporary source files? Thanks.

  • High quality software examples

    - by Francisco Garcia
    One of the best ways to learn about programming is reading high quality code/projects from great engineers. Which open-source projects do you think is worth looking at? I mean, that code that you can print and sit under a tree with a glass of wine and enjoy reading. If you can, also specify if the software is great to look at because its documentation, design, UML diagrams or just plain code. I believe UML is not very common within open-source projects. Is there such a thing as a project branch that polishes code and design with the sole objective to give other programmers a great example of great software?

  • Calling C# code from Java?

    - by Keith G
    Does anyone have a good solution for integrating some C# code into a java application? The code is small, so I could re-write in java, but I would rather reuse the code if possible. Don't repeat yourself, etc. Also, I know I can expose the C# as a web service or whatever, but it has some security/encryption stuff in there, so I would rather keep it tightly integrated if possible. Edit: It's going to be on a server-based app, so "downloading" another runtime is irrelevant.

  • Methods to see result fo a code change faster

    - by Can't Tell
    This question came to me when developing using Eclipse. I use JBoss Application Server and use hot code replacement. But this option requires that the 'build automatically' option to be enabled. This makes Eclipse build the workspace automatically (periodically or when a file is saved?) and for a large code base this takes too much time and processing which makes the machine freeze for a while. Also sometimes an error message is shown saying that hot code replacement failed. The question that I have is: is there a better way to see the result of a code change? Currently I have the following two suggestions: Have unit tests - this will allow to run a single test and see the result of a code change. ( But for a JavaEE application that uses EJBs is it easy to setup unit tests?) Use OSGi - which allows to add jars to the running system without bringing down the JVM. Any ideas on above suggestions or any other suggestion or a framework that allows to do this is welcome.

  • Setting a ListView Divider in code

    - by deSelby
    One of my ListView's needs to be created in code. When I specify a ListView in xml, I can set a dividerHeight and assign a color to the divider. But apparently, in code a color is not acceptable nor is pointing to a resource id. Only a Drawable is acceptable - and I haven't gotten to that chapter yet. Can someone point me to an example of setting a ListView divider in code?

  • Code generator tool to generate a property and backing field

    - by MattSlay
    I'm working in VS2008 and C#, and I'm looking for a (free) code generator tool to generate a property with getter and setter, as well as the backing private field to go with. The template thingy in VS does not make the field to go with it. Just looking for something a little bit better. I once saw a web site where you could build this code, then cust-and-paste it from the web page to your code.

  • Redundant code constructs

    - by Diomidis Spinellis
    The most egregiously redundant code construct I often see involves using the code sequence if (condition) return true; else return false; instead of simply writing return (condition); I've seen this beginner error in all sorts of languages: from Pascal and C to PHP and Java. What other such constructs would you flag in a code review?

  • Visual Studio Play Sound With No File Present

    - by jb
    It's fairly simple to play a sound file, say temp.wav, from Visual Studio C#. I'm looking for a way to do this without temp.wav being locatable from the machine running the program. IE - I want to read the .WAV file into my solution so that it is somehow inside of my .EXE and be played by it. Is this possible?

  • sysklogd ignores my log facilities

    - by Synther Lawrence
    I'm using sysklogd 1.5.5. All I want is to get local0 entries in /var/log/vr file. My conf: *.*;local0.none /var/log/messages local0.* /var/log/vr When I do logger -p local0.info "local0 test from logger" the message appear in /var/log/vr file. That's ok. But the following sends message to /var/log/messages instead of /var/log/vr: #include <stdlib.h> #include <syslog.h> int main(int argc, char const* argv[]) { openlog(NULL, LOG_PID, LOG_LOCAL0); syslog(LOG_INFO, "local0 test from app\n"); closelog(); return 0; } Where am I wrong?

  • What is a good FAT file system for ARM7-TDMI

    - by Seidleroni
    I'm using the ARM7TDMI-S (NXP processor) and I need a file system capable of reading/writing to an SD card. There are so many available, what have people used and been happy with? One that requires the least amount of setup is best - so the less I have to do to get it started (i.e. write device drivers to NXP's hardware) the better.
