  • Problem with Ruby script output being stored into a file

    - by nickf
    I have a Ruby script that outputs a heap of text. As an example: puts "line 1" puts "line 2" puts "line 3" # etc... (obviously, this isn't how my script works..) There's not a lot of data - perhaps about 8kb of character data in total. When I run the script on the command line, it works as expected: $ ./my-script.rb line 1 line 2 line 3 But, when I push it into a file, the output is truncated at exactly 4096 bytes: $ ./my-script.rb > output.txt What would cause it to stop at 4kb?

  • PowerShell: Read text, regex sort, write output to file and formatting

    - by Bill Hunter
    I am a Powershell novice and have run into a challenge in reading, sorting, and outputting a csv file. The input csv has no headers, the data is as follows: 05/25/2010,18:48:33,Stop,a1usak,10.128.212.212 05/25/2010,18:48:36,Start,q2uhal,10.136.198.231 05/25/2010,18:48:09,Stop,s0upxb,10.136.198.231 I use the following piping construct to read the file, sort and output to a file: (Get-Content d:\vpnData\u62gvpn2.csv) | %{,[regex]::Split($, ",")} | sort @{Expression={$[3]}},@{Expression={$_[1]}} | out-file d:\vpnData\u62gvpn3.csv The new file is written with the following format: 05/25/2010 07:41:57 Stop a0uaar 10.128.196.160 05/25/2010 12:24:24 Start a0uaar 10.136.199.51 05/25/2010 20:00:56 Stop a0uaar 10.136.199.51 What I would like to see in the output file is a similar format to the original input file with comma dilimiters: 05/25/2010,07:41:57,Stop,a0uaar,10.128.196.160 05/25/2010,12:24:24,Start,a0uaar,10.136.199.51 05/25/2010,20:00:56,Stop,a0uaar,10.136.199.51 But I can't quite seem to get there. I'm almost of the mind that I'll have to write another segment to read the newly produced file and reset its contents to the preferred format for further processing. Thoughts?

  • Help with output generated by this C code using fork()

    - by Seephor
    I am trying to figure out the output for a block of C code using fork() and I am having some problems understanding why it comes out the way it does. I understand that when using fork() it starts another instance of the program in parallel and that the child instance will return 0. Could someone explain step by step the output to the block of code below? Thank you. main() { int status, i; for (i=0; i<2; ++i){ printf("At the top of pass %d\n", i); if (fork() == 0){ printf("this is a child, i=%d\n", i); } else { wait(&status); printf("This is a parent, i=%d\n", i); } } }

  • Explanation of output

    - by Anon
    My program class Building { Building() { System.out.print("b "); } Building(String name) { this(); System.out.print("bn " + name); } }; public class House extends Building { House() { System.out.print("h "); // this is line# 1 } House(String name) { this(); // This is line#2 System.out.print("hn " + name); } public static void main(String[] args) { new House("x "); } } We know that compiler will write a call to super() as the first line in the child class's constructor. Therefore should not the output be: b (call from compiler written call to super(), before line#2 b (again from compiler written call to super(),before line#1 ) h hn x But the output is b h hn x Why is that?

  • C# - Realtime console output redirection

    - by Levo
    I'm developing a C# application and I need to start an external console program to perform some tasks (extract files). What I need to do is to redirect the output of the console program. Code like this one does not work, because it raises events only when a new line is writen in the console program, but the one I use "updates" what's shown in the console window, without writting any new lines. How can I raise an event every time the text in the console is updated? Or just get the output of the console program every X seconds? Thanks in advance!

  • Capturing system command output as a string

    - by dreeves
    Perl and PHP do this with backticks. For example: $output = `ls`; This code returns a directory listing into the variable $output. A similar function, system("ls"), returns the operating system return code for the given command. I'm talking about a variant that returns whatever the command prints to stdout. (There are better ways to get the list of files in a directory; the example code is an example of this concept.) How do other languages do this? Is there a canonical name for this function? (I'm going with "backtick"; though maybe I could coin "syslurp".)

  • Combining Multiple Queries and Parameters into One Operation

    - by shay.shmeltzer
    This question came up twice this week and while the solution is explained in a couple of previous blog entries I did, I thought that showing off the complete solution in a single video would be nice. The scenario is that you have two VOs with queries that are based on a parameter, I showed in the past how to create a parameter form that executes the query - and you can do this for both. But what if you actually need just one value to drive both queries? How do you combine two parameter forms and two buttons into one? This is what this video shows you. The steps are: Creating two parameter forms Setting the value of a parameter in the binding tab Creating a backing bean to execute the code for one button Adding the code to execute another operation Remarking the parts that can be dropped from the screen Check it out here:

  • Escape apostrophe when passing parameter in onclick event

    - by RememberME
    I'm passing the company name to an onclick event. Some company names have apostrophes in them. I added '.Replace("'", "'")' to the company_name field. This allows the onclick event to fire, but the confirm message displays as "Jane's Welding Company". <a href="#" onclick="return Actionclick('<%= Url.Action("Activate", new {id = item.company_id}) %>', '<%= Html.Encode(item.company1.company_name.Replace("'", "&#39;")) %>');" class="fg-button fg-button-icon-solo ui-state-default ui-corner-all"><span class="ui-icon ui-icon-refresh"></span></a> <script type="text/javascript"> function Actionclick(url, companyName) { if (confirm('This action will activate this company\'s primary company ('+companyName+') and all of its other subsidiaries. Continue?')) { location.href = url; }; };

Thanks, Spencer

    Hi. i have a j2ee web application running on spring framework and using log4j for logging. I have this line in my log4j.properties file. this will insert the logs in my database. How do I set a dynamic value in the message part so that I can somehow append the currently logged in user. The bean object containing info for the current user is in the application context. log4j.appender.dbLog.sql = INSERT INTO LOGGING (log_date, log_level, location, message) VALUES ('%d{yyyy/MM/dd HH:mm:ss}', '%-5p', '%C-%L', '%m')

  • Using a type parameter and a pointer to the same type parameter in a function template

    - by Darel
    Hello, I've written a template function to determine the median of any vector or array of any type that can be sorted with sort. The function and a small test program are below: #include <algorithm> #include <vector> #include <iostream> using namespace::std; template <class T, class X> void median(T vec, size_t size, X& ret) { sort(vec, vec + size); size_t mid = size/2; ret = size % 2 == 0 ? (vec[mid] + vec[mid-1]) / 2 : vec[mid]; } int main() { vector<double> v; v.push_back(2); v.push_back(8); v.push_back(7); v.push_back(4); v.push_back(9); double a[5] = {2, 8, 7, 4, 9}; double r; median(v.begin(), v.size(), r); cout << r << endl; median(a, 5, r); cout << r << endl; return 0; } As you can see, the median function takes a pointer as an argument, T vec. Also in the argument list is a reference variable X ret, which is modified by the function to store the computed median value. However I don't find this a very elegant solution. T vec will always be a pointer to the same type as X ret. My initial attempts to write median had a header like this: template<class T> T median(T *vec, size_t size) { sort(vec, vec + size); size_t mid = size/2; return size % 2 == 0 ? (vec[mid] + vec[mid-1]) / 2 : vec[mid]; } I also tried: template<class T, class X> X median(T vec, size_t size) { sort(vec, vec + size); size_t mid = size/2; return size % 2 == 0 ? (vec[mid] + vec[mid-1]) / 2 : vec[mid]; } I couldn't get either of these to work. My question is, can anyone show me a working implementation of either of my alternatives? Thanks for looking!

  • How to make a parameter optional in WSDL?

    - by user305069
    I have a WebService API which needs 2 of its parameters to be optional in the WSDL public wsProxy[] Insert(wsProxy[] proxies, string loginname, string password, bool returnNewData) { //code here } I need to a way to show loginname and password as optional in the WSDL. Is there any way to do this in C#. Can I maybe add an tag in front of the parameters like this [optional]loginname? I have been looking around but haven't been able to find anything so far.

  • PHP: variable-length argument list by reference?

    - by GetFree
    Is it possible to create a PHP function that takes a variable number of parameters all of them by reference? It doesn't help me a function that receives by reference an array of values nor a function that takes its arguments wrapped in an object because I'm working on function composition and argument binding. Don't think about call-time pass-by-reference either. That thing shouldn't even exist.

  • Delphi low-level machine parameter access

    - by tonyhooley.mp
    There are many very low-level parameters measured by PCs and their processors (e.g. core temperatures, fan-speeds, voltage levels at various parts of the motherboard and processor internals) which are available and displayed by the BIOS, and by some aaplication programs. How does one access these low-level (real-time) data via Delphi? Is there a library? Is there a Windows API?

  • How to run javascript on an ajax output?

    - by WAC0020
    I am using jquery-ui tabs and ajax to load the content of the tabs. Here is my javascript: $(document).ready(function() { $("#tabs").tabs({ fx: { opacity: 'toggle' } }); $('.hd_item').hover(function() { //Display the caption $(this).find('span.hd_caption').stop(false,true).fadeIn(600); }, function() { //Hide the caption $(this).find('span.hd_caption').stop(false,true).fadeOut(400); }); }); When the user clicks on the tab is will load the content.php via ajax. The output of the ajax is: <li class="hd_item"> <img title="Backyard Brawl" alt="Backyard Brawl" src="games/normal_icons/1844.png" id="hd_icon"> <span class="hd_caption"> <h1>Backyard Brawl</h1> <p id="hd_description">In this game you pick a player and beat each other up with ...</p> <p id="hd_stat">Added: <br>2009-12-14</p><a href="/dirtpilegames/index.php?ground=games&amp;action=play&amp;dig=backyard-brawl">PLAY</a> </span> </li> The problem that I am having is the javascript is not working on the ajax output.

  • C++ this as thread parameter, variables unavailable

    - by brecht
    I have three classes: class Rtss_Generator { int mv_transfersize; } class Rtss_GenSine : Rtss_Generator class Rtss_GenSineRpm : Rtss_GenSine Rtss_GenSine creates a thread in his constructer, it is started immediatly and the threadfunction is off-course declared static, waiting for an event to start calculating. the problem: all the variables that are accessed through the gen-pointer are 0, but it does not fail. Also, this-address in the constructer and the gen-pointer-address in the thread are the same, so the pointer is ok. this code is created and compile in visual studio 6.0 service pack 2003 ORIGINAL CODE no thread Rtss_GenSine::getNextData() { //[CALCULATION] //mv_transferSize is accessible and has ALWAYS value 1600 which is ok } NEW CODE Rtss_GenSine::Rtss_GenSine() { createThread(NULL, threadFunction, (LPVOID) this,0,0); } Rtss_GenSine::getNextData() { SetEvent(startCalculating); WaitForSingleObject(stoppedCalculaing, INFINITE); } DWORD Rtss_GenSine::threadFunction(LPVOID pParam) { Rtss_GenSine* gen = (Rtss_GenSine*) pParam; while(runThread) { WaitForSingleObject(startCalculating, INFINITE); ResetEvent(startCalculating) //[CALCULATION] //gen->mv_transferSize ---> it does not fail, but is always zero //all variables accessed via the gen-pointer are 0 setEvent(stoppedCalculaing) } }

    Hello, I would like to pass to a jQuery function a regular function, instead of the usual anonymous function, but I'm not sure how such a thing could be done. Instead of this: function setVersion(feature) { $.post("some.php", { abc:"abc" }, function(data){ // do something here }, "json"); } I would like to do this: function foo(data){ // do something here } function setVersion(feature) { $.post("some.php", { abc:"abc" }, foo, "json"); } Thank you.

  • C# method generic params parameter bug?

    - by Mike M
    Hey, I appears to me as though there is a bug/inconsistency in the C# compiler. This works fine (first method gets called): public void SomeMethod(string message, object data); public void SomeMethod(string message, params object[] data); // .... SomeMethod("woohoo", item); Yet this causes "The call is ambiguous between the following methods" error: public void SomeMethod(string message, T data); public void SomeMethod(string message, params T[] data); // .... SomeMethod("woohoo", (T)item); I could just use the dump the first method entirely, but since this is a very performance sensitive library and the first method will be used about 75% of the time, I would rather not always wrap things in an array and instantiate an iterator to go over a foreach if there is only one item. Splitting into different named methods would be messy at best IMO. Thoughts?
