  • refreshing javascript by renaming src attribute

    - by Eric Fortis
    I want to refresh the output of the script below. Is this json? Do I need to add a crossdomain policy in my site? <div id="nowplaying"> <script src="http://s4.total-streaming.com/xml.php?station=1269&get=js"></script> </div> Edit: This is what I'm trying based on @alexn advise, but still doesn't refresh. <div id="nowplaying"> <script id="nowplaying-script" src="http://s4.total-streaming.com/xml.php?station=1269&get=js"></script> <script> setInterval(function () { $('#nowplaying-script').attr('src', 'http://s4.total-streaming.com/xml.php?station=1269&get=js'); }, 1000); </script> </div> Note Firebug: Resource interpreted as script but transferred with MIME type text/html. xml.php:-1

  • PHP While Loops from Arrays

    - by Michael
    I have a table that contains members names and a field with multiple ID numbers. I want to create a query that returns results where any values in the ID fields overlap with any values in the array. For example: lastname: Smith firstname: John id: 101, 103 I have Array #1 with the values 101, 102, 103 I want the query to output all members who have the values 101 or 102 or 103 listed in their id field with multiple ids listed. Array ( [0] => 101 [1] => 102 [2] => 103 ) $sql="SELECT firstname, lastname, id FROM members WHERE id LIKE '%".$array_num_1."%'"; $result=mysql_query($sql); while ($rows=mysql_fetch_array($result)) { echo $rows['lastname'].', '.$rows['firstname'].'-'.$rows['id']; }

  • How do I assign by "reference" to a class field in c#?

    - by Jamie
    I am trying to understand how to assign by "reference" to a class field in c#. I have the follwing example to consider: public class X { public X() { string example = "X"; new Y( ref example ); new Z( ref example ); System.Diagnostics.Debug.WriteLine( example ); } } public class Y { public Y( ref string example ) { example += " (Updated By Y)"; } } public class Z { private string _Example; public Z( ref string example ) { this._Example = example; this._Example += " (Updated By Z)"; } } var x = new X(); When running the above code the output is: X (Updated By Y) And not: X (Updated By Y) (Updated By Z) As I had hoped. It seems that assigning a "ref parameter" to a field loses the reference. Is there any way to keep hold of the reference when assigning to a field? Thanks.

  • ModX: Selecting and outputting specific menu items using Wayfinder

    - by Staffan Estberg
    tI've been trying to output specific menu items, also wanting to change the names of some, without satisfying results. The problem is that I have three different menu setups throughout the site - the header split into two sections and the footer divided into a couple of columns. This is what I've tried so far - [[Wayfinder? &startId=0 &level=1 &limit=5 &excludeDocs=49,61,55]] While it works excluding all the other links isn's the most optimal solution as there are 11 in total plus I want to be able to 1. rearrange the order and 2. change the names of two of them. Is this possible at all using the Wayfinder or do I have to create a snippet? Thanks in advance.

  • Bash: how to supress newlines?

    - by gilgongo
    I'm trying to extract fields from a pipe-delimited file and provide them as arguments to an external program in a loop. The file contains lines like this: value1|value2 value3|value4 So I came up with: while read line; do echo -n "${line}" | awk -F '|' '{print $1}'; echo -n " something "; echo -n "${line}" | awk -F '|' '{print $2}'; echo " somethingelse"; done < <(cat $FILE) I want to see the following output: value1 something value2 somethingelse value3 something value4 somethingelse But instead I'm getting: value1 something value2 somethingelse value3 something value4 somethingelse Perhaps I shouldn't be using echo?

  • Verifying compiler optimizations in gcc/g++ by analyzing assembly listings

    - by Victor Liu
    I just asked a question related to how the compiler optimizes certain C++ code, and I was looking around SO for any questions about how to verify that the compiler has performed certain optimizations. I was trying to look at the assembly listing generated with g++ (g++ -c -g -O2 -Wa,-ahl=file.s file.c) to possibly see what is going on under the hood, but the output is too cryptic to me. What techniques do people use to tackle this problem, and are there any good references on how to interpret the assembly listings of optimized code or articles specific to the GCC toolchain that talk about this problem?

  • 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.

  • MSSQL "for xml", multiple tables, multiple nodes

    - by Nelson
    Is it possible to select multiple tables at once? For example, I can do: SELECT ( SELECT * FROM Articles FOR XML PATH('article'), TYPE ) FOR XML PATH('articles'), ROOT('data') and SELECT ( SELECT * FROM ArticleTypes FOR XML PATH('articleType'), TYPE ) FOR XML PATH('articleTypes'), ROOT('data') Can I join both so that I get the following output? I can't use UNION because the table structures don't match. <data> <articles> <article>...</article> ... </articles> <articleTypes> <articleType>...</articleType> ... </articleTypes> </data>

  • How do I modify gitstats to only utilize a specified file extension for it's statistics?

    - by Fake Code Monkey Rashid
    Hello good people! The website of the statistics generator in question is: http://gitstats.sourceforge.net/ It's git repo can be cloned from: git clone git://repo.or.cz/gitstats.git What I want to do is something like: ./gitstatus --ext=".py" /input/foo /output/bar Failing being able to easily pass the above option without heavy modification, I'd just hardcore the file extentsion I want to be included. However, I'm unsure of the relevant section of code to modify and even if I did no, I'm unsure of how to start such modifications. It's seems like it'd be rather simple but alas...

  • jQuery, ajax request doesn't success with JSON on IE

    - by sylouuu
    I made an AJAX call and it works on FF & Chrome but not on IE 7-8-9. I'm loading a JSON file from my domain: $.ajax({ url: 'js/jquery.desobbcode.json', dataType: 'json', cache: false, success: function(json) { alert('ok'); }, error: function(xhr, errorString, exception) { alert("xhr.status="+xhr.status+" error="+errorString+" exception="+exception); } }); I also tried by adding contentType: 'application/json' but I receive the same output which is : xhr.status=200 error=parsererror exception=SyntaxError Unterminated string constant I checked my JSON file with JSONLint and it's OK. I checked if there is an extra comma and the content is also trimmed. See my JSON file If I put dataType: 'text', I receive the OK alert but a debug popup too. Could you help me? Regards.

  • how to cast an array of char into a single integer number?

    - by SepiDev
    Hi guys, i'm trying to read contents of PNG file. As you may know, all data is written in a 4-byte manner in png files, both text and numbers. so if we have number 35234 it is save in this way: [1000][1001][1010][0010]. but sometimes numbers are shorter, so the first bytes are zero, and when I read the array and cast it from char* to integer I get wrong number. for example [0000] [0000] [0001] [1011] sometimes numbers are misinterpreted as negative numbers and simetimes as zero! let me give you an intuitive example: char s_num[4] = {120, 80, 40, 1}; int t_num = 0; t_num = int(s_num); => 3215279148 ?????? the result should be 241 but the output is 3215279148? I wish I could explain my problem well! how can i cast such arrays into a single integer value?

  • Why is my implementation of strcmp not returning the proper value?

    - by Avanish Giri
    Why is this printing out 0 back in main but 6 when it is inside of the strcmp function? 7 int main() 8 { 9 char* str = "test string"; 10 char* str2 = "test strong"; 11 //printf("string length = %d\n",strlen(str)); 12 13 int num = strcmp(str,str2); 14 15 printf("num = %d\n",num); 16 } 29 int strcmp(char* str, char* str2) 30 { 31 if(*str == '\0' && *str2 == '\0') 32 return 0; 33 if(*str2 - *str == 0) 34 { 35 strcmp(str+1,str2+1); 36 } 37 else 38 { 39 int num = *str2 - *str; 40 cout << "num = " <<num<<endl; 41 return num; 42 } 43 } The output is: num = 6 num = 0 Why is it printing 0 when obviously the value that it should be returning is 6?

  • Add up values from a text file

    - by Stanley
    Hi Guys I have a text file that contains Amounts at Substring (34, 47) of each line. I need to sum Up all the Values to the End of the File. I have this code that I had started to build but I do not know how to proceed from here: public class Addup { /** * @param args the command line arguments */ public static void main(String[] args) throws FileNotFoundException, IOException { // TODO code application logic here FileInputStream fs = new FileInputStream("C:/Analysis/RL004.TXT"); BufferedReader br = new BufferedReader(new InputStreamReader(fs)); String line; while((line = br.readLine()) != null){ String num = line.substring(34, 47); double i = Double.parseDouble(num); System.out.println(i); } } } The output is like this: 1.44576457E4 2.33434354E6 4.56875685E3 The Amount is in two decimal Places and I need the result also in the Two decimal Places.

  • How Do I Remove The First 4 Characters From A String If It Matches A Pattern In Ruby

    - by James
    I have the following string: "h3. My Title Goes Here" I basically want to remove the first 4 characters from the string so that I just get back: "My Title Goes Here". The thing is I am iterating over an array of strings and not all have the h3. part in front so I can't just ditch the first 4 characters blindly. I have checked the docs and the closest think I could find was chomp, but that only works for the end of a string. Right now I am doing this: "h3. My Title Goes Here".reverse.chomp(" .3h").reverse This gives me my desired output, but there has to be a better way right? I mean I don't want to reverse a string twice for no reason. I am new to programming so I might have missed something obvious, but I didn't see the opposite of chomp anywhere in the docs. Is there another method that will work? Thanks!

  • doubt in sizeof implementation

    - by aks
    Below is the program to find the size of a structure without using sizeof operator: struct MyStruct { int i; int j; }; int main() { struct MyStruct *p=0; int size = ((char*)(p+1))-((char*)p); printf("\nSIZE : [%d]\nSIZE : [%d]\n", size); return 0; } My doubt is: Why is typecasting to char * required? If I don't use the char* pointer, the output is 1 - WHY?

    In order to share some more tips and tricks for R, what is you single-most useful feature or trick? Clever vectorization? Data input/output? Visualization and graphics? Statistical analysis? Special functions? The interactive environment itself? One item per post, and we will see if we get a winner by means of votes. [Edit 25-Aug 2008]: So after one week, it seems that the simple str() won the poll. As I like to recommend that one myself, it is an easy answer to accept.

  • JQuery:FullCalendar Plugin: Events are not shown in week view and day view but are shown in month vi

    - by bocode
    I've the following code to fetch events: $('#calendar').fullCalendar({ theme: true, slotMinutes: 10, header: { left: 'prev,next today', center: 'title', right: 'month,agendaWeek,agendaDay', }, defaultView: 'agendaDay', allDaySlot: false, editable: false, events: "/cgi-bin/shlk/getshlkruns.pl" }); The output from getshlkruns.pl is fairly simple json feed: [{'title': 'Successful','start': 1266398223,'end': 1266398266,'url': '/shlk/cgi-bin/getshlkrunlog.pl?i=21'}] There are several events like above (i've removed for brevity sake). So the above events show up when am in the month view but mysteriously absent when am in week or day view. What am doing wrong here? Thanks in advance for your answers.

  • Can I override a theme function with a .tpl file?

    - by Nick Lowman
    Hi everyone, How would I go around overriding a theme function with a .tpl file? I know how to override a .tpl file with a theme function but not the other way round. I can't seem to find anywhere that tells me so, so maybe it's not possible or not good practise. For example if there was a theme function defined in a module called super_results and registered with the theme registry, like the example below, how would I go around overriding it with super_results.tpl.php. 'super_results' => array( 'arguments' => array('title' => NULL, 'results' => NULL, 'votes' => NULL), ), function modulename_super_results($title, $results,$votes){ output HTML }

  • Best approch for building link in JQuery with paramaters

    - by MrW
    Hi, Very new to JQuery and MVC and webdevelopment over all. I'm now trying to accomplish this and is asking for a bit of advise: I'm basically trying to build a filter with 4 input elements, and 1 output. I have 4 select (drop down) elements in my page. As soon as one of them is changed, I need to build a href and get the partial view with the return values. My questionis now if I should try to build the href in the select element or if I can do it once in jquery, and don't have to have duplicated code. How would I accomplish this?

  • Reverse Bredth First Search in C#

    - by Ngu Soon Hui
    Anyone has a ready implementation of the Reverse Bredth First Search algorithm in C#? By Reverse Bredth First Search, I mean instead of searching a tree starting from a common node, I want to search the tree from the bottom and gradually converged to a common node. Let's see the below figure, this is the output of a Bredth First Search: In my reverse bredth first search, 9,10,11 and 12 will be the first few nodes found ( the order of them are not important as they are all first order). 5, 6, 7 and 8 are the second few nodes found, and so on. 1 would be the last node found. Any ideas or pointers?

  • How do I set up Scala plugin for NetBeans to copy the Scala runtime library?

    - by Alexey Romanov
    Versions: NetBeans 6.8, Scala Kit 0.16.1 When I compile my project, I get the following output: init: deps-jar: Compiling 2 source files to F:\MyProgramming\NorvigSpellChecker\build\classes compile: Created dir: F:\MyProgramming\NorvigSpellChecker\dist Building jar: F:\MyProgramming\NorvigSpellChecker\dist\NorvigSpellChecker.jar Not copying the libraries. To run this application from the command line without Ant, try: java -jar "F:\MyProgramming\NorvigSpellChecker\dist\NorvigSpellChecker.jar" jar: BUILD SUCCESSFUL (total time: 3 seconds) Of course, the libraries should be copied, so I can't actually run it by using this command line. I don't see any options to copy the library in the project configuration. The plugin uses Ant for building, but I don't have any experience with it; presumably it should be easy enough to tell Ant to copy the libraries. Here is build-impl.xml, what should I do in build.xml?

  • Multiple ASP.Net Controls On One Page

    - by Duracell
    We have created a User Control for ASP.Net. At any one time, a user's profile page could contain between one and infinity of these controls. The Control.ascx file contains quite a bit of javascript. When the control is rendered by .Net to HTML, you notice that it prints the javascript for each control. This was expected. I'd like to reduce the amount of HTML output by the server to increase page load times. Normally, you could just move the javascript to an external file and then you only need one extra HTTP request which will serve for all controls. But what about instances in the javascript where we have something like document.getElementById('<%= txtTextBox.ClientID %'); How would the javascript know which user control work with? Has anyone done something like this, or is the solution staring me in the face?

  • Razor support of generic extension methods

    - by Brian
    Hello, With regards to the Razor view engine, say I want to render Html.TextBoxFor<SomeModel>(i => i.Name), it doesn't seem that the inline syntax works as in: @Html.TextBoxFor<SomeModel>(i => i.Name) This doesn't seem to work because it interprets the generic as an HTML tag. I could use a code-block approach, but then what's the best approach to output the content? The HTML string returned from this method, do I response.write it, or is there a syntax for it, or what's the approach? Thanks.

  • Getting closure-compiler and Node.js to play nice

    - by bukzor
    Are there any projects that used node.js and closure-compiler (CC for short) together? The official CC recommendation is to compile all code for an application together, but when I compile some simple node.js code which contains a require("./MyLib.js"), that line is put directly into the output, but it doesn't make any sense in that context. I see a few options: Code the entire application as a single file. This solves the problem by avoiding it, but is bad for maintenance. Assume that all files will be concatenated before execution. Again this avoids the problem, but makes it harder to implement a un-compiled debug mode. I'd like to get CC to "understand" the node.js require() function, but that probably can't be done without editing the compiler itself, can it?
