  • phpbb template comment conditional

    - by john
    I see in PHPBB they use conditional statements inside their html, or xhtml, if you dont know what I mean here is a snippet: <!-- IF MODERATORS --> <p class="moderators"><!-- IF S_SINGLE_MODERATOR -->{L_MODERATOR}<!-- ELSE -->{L_MODERATORS}<!-- ENDIF -->: {MODERATORS}</p> <!-- ENDIF --> <!-- IF U_MCP --> <p class="linkmcp">[ <a href="{U_MCP}">{L_MCP}</a> ]</p> <!-- ENDIF --> Is there an explanation on how to implement this in my own site, as it would be very useful and clean up a lot of code.

  • Can simple javascript inheritance be simplified even further?

    - by Will
    John Resig (of jQuery fame) provides a concise and elegant way to allow simple JavaScript inheritance. It was so short and sweet, in fact, that it inspired me to try and simplify it even further (see code below). I've modified his original function such that it still passes all his tests and has the potential advantage of: readability (50% less code) simplicity (you don't have to be a ninja to understand it) performance (no extra wrappers around super/base method calls) consistency with C#'s base keyword Because this seems almost too good to be true, I want to make sure my logic doesn't have any fundamental flaws/holes/bugs, or if anyone has additional suggestions to improve or refute the code (perhaps even John Resig could chime in here!). Does anyone see anything wrong with my approach (below) vs. John Resig's original approach? if (!window.Class) { window.Class = function() {}; window.Class.extend = function(members) { var prototype = new this(); for (var i in members) prototype[i] = members[i]; prototype.base = this.prototype; function object() { if (object.caller == null && this.initialize) this.initialize.apply(this, arguments); } object.constructor = object; object.prototype = prototype; object.extend = arguments.callee; return object; }; } And the tests (below) are nearly identical to the original ones except for the syntax around base/super method calls (for the reason enumerated above): var Person = Class.extend( { initialize: function(isDancing) { this.dancing = isDancing; }, dance: function() { return this.dancing; } }); var Ninja = Person.extend( { initialize: function() { this.base.initialize(false); }, dance: function() { return this.base.dance(); }, swingSword: function() { return true; } }); var p = new Person(true); alert("true? " + p.dance()); // => true var n = new Ninja(); alert("false? " + n.dance()); // => false alert("true? " + n.swingSword()); // => true alert("true? " + (p instanceof Person && p instanceof Class && n instanceof Ninja && n instanceof Person && n instanceof Class));

  • What is the maximum sandbox size on iPad?

    - by John Alexander
    I'm writing an iPad app that acts as a media player (video and photos). I know there is a 2GB size limit on apps, however is this the size limit on an app when downloaded? Or the limit on the size of your sandbox throughout the life of the app? For example what if my small app later on downloads various media files to its sandbox that put the user over 2GB total (app + downloaded media)? Thanks!

  • Single Form with Multiple Dynamic Buttons

    - by John Reilly
    I've spent hours/days trying to figure this out and now I'm completely perplexed so I thought I'd give stackoverflow a try. I'm (a newb) working in Java/JSP using Eclipse hosting on Google App Engine trying to develop an app for a volunteer organization I'm a member of. Rather than embarrass myself by showing my current code I'd love just a nudge in the right direction. I have a form (which doubles as a report basically) showing "people" grouped under the "task" they are currently working on. I would like to select multiple people from multiple tasks and reassign them to another task e.g. Bill and Jane are Gardening, Jeff is Painting. I want to select Jane and Jeff (all people have an associated checkbox in the form) and re-assign them to Sweeping (which is a task on the form but has no people assigned to it yet). Ideally, the re-assignment to Sweeping would be via a Sweeping button (each task would have a dynamically-created task button) that would pass the "Sweeping" value to a servlet along with an array or list of people whose checkbox has been checked. The servlet would handle the request (creating an Assignment "object/entity" with timeStamp, personId, taskId) and then re-direct back to the form/report which would then repaint with the current tasks/people generated from the Assignments class in the datastore. All the tasks are user-defined and retrieved from the database when building the form. Ditto the people. I've been trying to keep the jsp for presentation and the servlets for the processing but I'm no purist and would just like to get unstuck. Many thanks in advance for your assistance.

  • mod_rewrite/GoDaddy problem

    - by John Deerhake
    Ok, so I really don't know much about mod_rewrite and I'm looking over the apache docs and still not figuring this out. Here is my htaccess (which is mostly just copy & pasted from a site I found): .htaccess in base dir: <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^$ public/ [L] RewriteRule (.*) public/$1 [L] </IfModule> .htaccess in /public dir: <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?url=$1 [PT,L] </IfModule> Basically I'm using the above htaccess files on my current test server and it works great and exactly like I would expect (everything gets seamlessly redirected to public dir). Now when I throw this on my GoDaddy hosting account i get "Internal Server Errror". I've done some searching and I'm fairly certain I should be able to use mod_rewrite with GoDaddy. I suspect this is because I'm not using the base directory to host the site in. The site is in in the folder html/myapp/ (where html is the base directory) and i have a subdomain set up in GoDaddy to look in that folder.

  • IE6 PNG-transparency CSS hack not working

    - by John
    I looked around and decided to use a CSS approach rather than rely on JS... I figure the kind of corporate users stuck with IE6 might also have JS disabled by IT departments. So In my HTML I have: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" /> <title>My Page</title> <link rel="stylesheet" type="text/css" href="default.css" /> <!--[if IE 6]><link rel="stylesheet" type="text/css" href="ie6.css"><![endif]--> </head> <body> <img src="media/logo.png"/> </body> Then my ie6.css consists simply of: img { filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(...); } However none of this makes the slightest difference, no transparency. I commented out all the rest of the page so it is literally that one and still no luck. I removed the default.css stylesheet and still no difference.

  • How to thoroughly purge and reinstall postgresql on ubuntu?

    - by John Mee
    Somehow I've managed to completely bugger the install of postgresql on Ubuntu karmic. I want to start over from scratch, but when I "purge" the package with apt-get it still leaves traces behind such that the reinstall configuration doesn't run properly. After I've done: apt-get purge postgresql apt-get install postgresql It said Setting up postgresql-8.4 (8.4.3-0ubuntu9.10.1) ... Configuring already existing cluster (configuration: /etc/postgresql/8.4/main, data: /var/lib/postgresql/8.4/main, owner: 108:112) Error: move_conffile: required configuration file /var/lib/postgresql/8.4/main/postgresql.conf does not exist Error: could not create default cluster. Please create it manually with pg_createcluster 8.4 main --start or a similar command (see 'man pg_createcluster'). update-alternatives: using /usr/share/postgresql/8.4/man/man1/postmaster.1.gz to provide /usr/share/man/man1/postmaster.1.gz (postmaster.1.gz) in auto mode. Setting up postgresql (8.4.3-0ubuntu9.10.1) ... I have a "/etc/postgresql" with nothing in it and "/etc/postgresql-common/" has a 'pg_upgradecluser.d' directory and root.crt and user_clusters files. The /etc/passwd has a postgres user; the purge script doesn't appear to touch it. There's been a bunch of symptoms which I work through only to expose the next. Right this second, when I run that command "pg_createcluster..." it complains that '/var/lib/postgresql/8.4/main/postgresql.conf does not exist', so I'll go find one of those but I'm sure that won't be the end of it. Is there not some easy one-liner (or two) which will burn it completely and let me start over?

  • Adding "Next Topic" and "Previous Topic" Buttons to 130 webpages, code not working unless alerted fi

    - by John Guise
    I have put "Next Topic" and "Previous Topic" ( fixed)on each web page so you can click to move one page back or forward through the web site. Here is the code: $(document).ready(function($){ $("#fixed").prepend(''); $("#fixed").prepend(''); $('#nt').css({'position':'relative','top':'0','left':'24px','font-size':'9px'}); $('#pt').css({'position':'relative','top':'0','left':'0','font-size':'9px'}); var fname = document.location.href; var thistopic = (fname).split('/').pop(); alert(thistopic); var nexttopic = $('#jsddm li a'); nexttopic.each(function(index) { var ref = $(this).attr('href'); if (ref == thistopic){ var num =(index) }else{ return; } var flnk =($(nexttopic)[num+1].getAttribute('href', 2)); var blnk =($(nexttopic)[num-1].getAttribute('href', 2)); $('#nt').live('click', function(){ location.href=flnk; }); $('#pt').live('click', function(){ location.href=blnk; }); }); }); id=nt is the "Next Topic" Button,id=pt is the "Previous Topic" Button flnk is the HREF of the next topic page, blnk is the HREF of the prvious topic page. HREFs are grabbed from - ul#jsddm li ul li a - a large unordered list menu. This code works correctly if I have the eighth line included "alert(nexttopic)" If I take this line out (which I want to, as I do not want alert box popping up) - then the code will not work. Can anybody put me right please, so the buttons work without "alert(nexttopic)" line included

  • HttpContext.Current.Request.UserHostName is empty when called from a class

    - by John Galt
    I have various web pages that need to build up a URL to display or place it in an emitted email message. The code I inherited had this value for the name of the webserver in a Public Const in a Public Class called FixedConstants. For example: Public Const cdServerName As String = "WEBSERVERNAME" Trying to improve on this, I wrote this: Public Class UIFunction Public Shared myhttpcontext As HttpContext Public Shared Function cdWebServer() As String Dim s As New StringBuilder("http://") Dim h As String h = String.Empty Try h = Current.Request.ServerVariables("REMOTE_HOST").ToString() Catch ex As Exception Dim m As String m = ex.Message.ToString() 'Ignore this should-not-occur thingy End Try If h = String.Empty Then h = "SomeWebServer" End If s.Append(h) s.Append("/") Return s.ToString() End Function I've tried different things while debugging such as HttpContext.Current.Request.UserHostName and I always get an empty string which pumps out my default string "SomeWebServer". I know Request.UserHostName or Request.ServerVariables("REMOTE_HOST") works when invoked from a page but why does this return empty when invoked from a called method of a class file (i.e. UIFunction.vb)?

  • What libraries are available to record a user browsing your website for usability testing?

    - by John
    I remember seeing a JavaScript library a long time ago that offered the ability to record where users clicked and moved their mouse on your website, in order to do usability testing. I can't seem to find it anymore. Are there any libraries out there that do something like this? What I'm looking for is something like http://clixpy.com/, where you can include some javascript on a page and get videos of what users do.

  • I'm looking for a better solution on importing catalog data into Adobe InDesign

    - by John Thompson
    The last time I produced a catalog I used a software called EasyCatalog that worked with Adobe InDesign to merge data from a spreadsheet with graphics. I wouldn’t say it was completely successful. I know of one other catalog building software called Catalog Builder by Computer Pundits. I'm just looking for any suggestions from someone who might have gone through this process on what software I should use.

  • How to add a column via a query which counts the total rows with a specific criteria in a table with circular relationship in MS ACCESS 2007

    - by Xaqron
    I have a simple table "Employees" with this fields: ID, ParentID, Name ParentID is Nullable since an employee may have no Manager. This table has a one-to-many relationship with itself: ID --one--to--many--> ParentID Now I want a query which returns this columns: Name, Count of rows where their ParentID equals to the current row ID (the row is the manager of that rows) Sample Table: ID | ParentID | Name ====================== 1 | 0 | John ---------------------- 2 | 1 | Bob ---------------------- 3 | 1 | Alice ---------------------- 4 | 3 | Jack This way I can find an employee is the manager of how many other employees. The result should be something like this: Name | Count of Employees ========================== John | 2 -------------- Bob | 0 -------------- Alice | 1 -------------- Jack | 0 How can I achieve this in MS ACCESS 2007? * I have tried built-in query builder without any success.

  • Using rvm with a standalone ruby script

    - by John Yeates
    I have rvm installed on a Mac OS X 10.6 system with the system ruby and 1.9.1. I also have this basic ruby script: #!/usr/bin/ruby require 'curb-fu' I need the script to use the system ruby regardless of what rvm's using at any given time; I'm assuming that I've got that right, at least. I've switched to the system ruby (rvm use system) and then installed the gem (gem install curb-fu). If I run irb and type require 'curb-fu', it works. However, running that script with ./myscript.rb fails: /Users/me/bin/podcast_notify.rb:6:in `require': no such file to load -- curb-fu (LoadError) from /Users/me/bin/podcast_notify.rb:6 What's going wrong here? How do I install curb-fu so that it's always available to this script?

  • Can't get NSDate to work correctly

    - by John
    Hello, having a strange issue, must be something I'm just not seeing. I set up a variable in the .h NSDate *checkIn; @property (nonatomic, retain) NSDate *checkIn; I'm setting a variable to todays date in the initWithNibName: checkIn = [NSDate date]; I also did synthesized it as well. Now later on in my program I use it to build a tablecell with the following line cell.textLabel.text = [dateFormatter stringFromDate:checkIn]; This line kills the simulator, BAD_EXEC. If I put in a checkIn = [NSDate date]; above it, it works fine. So I'm thinking the variable isn't being stored from when I set it in the initWithNibName: Not sure why though, as my strings I do the same way are all working fine from method to method. What am I missing?

  • Finding duplicate values in a SQL table - ADVANCED

    - by Alex
    It's easy to find duplicates with one field SELECT name, COUNT(email) FROM users GROUP BY email HAVING ( COUNT(email) > 1 ) So if we have a table ID NAME EMAIL 1 John [email protected] 2 Sam [email protected] 3 Tom [email protected] 4 Bob [email protected] 5 Tom [email protected] This query will give us John, Sam, Tom, Tom because they all have the same e-mails. But what I want, is to get duplicates with the same e-mails and names. I want to get Tom, Tom. I made a mistake, and allowed to insert duplicate name and e-mail values. Now I need to remove/change the duplicates. But I need to find them first.

  • Regressing panel data in SAS.

    - by John
    Hey Guys, thanks to your help I succesfully managed all my databases! I am now looking at a panel data set on which I have to regress. Since I only started my Phd this semester together with the econometrics courses I am still new to many statistic applications and regression methods. I want to do a simple regression as in Y = x1 x2 x3 etc, now I already browsed through some literature and found that for panel data it's common to do a fixed effects regression. Also, my Y variable only has positive values so I was thinking in the direction of a Tobit model? I'm doing some research concerning the coverage of analysts in the financial business. My independent variable is the coverage of analysts on a certain firm, so per observation i have 1 analyst and 1 firm, together with different characteristics(market cap and betas etc) of the firm. All this data is monthly. As coverage cannot become negative (only 0) I was thinking of a Tobit model? Do you guys have any ideas what would be a good regression method? Or have some good sources (e books, written books, through university I have access to almost anything concerning my field of work) of information (cause I do have to learn these things for future research)? Thanks!

  • redrawing on ncurses

    I'm trying to redraw the content of a simple loop. So far it prints out to the stdscr 100 lines, and then by using scrl to scroll n lines I get n blank rows. What I want is to keep with the sequence. However, I'm not sure how to redraw the stdscr with the n extra lines. Any ideas will be appreciate it! #include <ncurses.h> int main(void) { initscr(); int maxy,maxx,y; getmaxyx(stdscr,maxy,maxx); scrollok(stdscr,TRUE); for(y=0;y<=100;y++) mvprintw(y,0,"This is some text written to line %d.",y); refresh(); getch(); scrl(5); refresh(); getch(); endwin(); return(0); }

  • XSLT multiple string replacement with recursion

    - by John Terry
    I have been attempting to perform multiple (different) string replacement with recursion and I have hit a roadblock. I have sucessfully gotten the first replacement to work, but the subsequent replacements never fire. I know this has to do with the recursion and how the with-param string is passed back into the call-template. I see my error and why the next xsl:when never fires, but I just cant seem to figure out exactly how to pass the complete modified string from the first xsl:when to the second xsl:when. Any help is greatly appreciated. <xsl:template name="replace"> <xsl:param name="string" select="." /> <xsl:choose> <xsl:when test="contains($string, '&#13;&#10;')"> <xsl:value-of select="substring-before($string, '&#13;&#10;')" /> <br/> <xsl:call-template name="replace"> <xsl:with-param name="string" select="substring-after($string, '&#13;&#10;')"/> </xsl:call-template> </xsl:when> <xsl:when test="contains($string, 'TXT')"> <xsl:value-of select="substring-before($string, '&#13;TXT')" /> <xsl:call-template name="replace"> <xsl:with-param name="string" select="substring-after($string, '&#13;')" /> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:value-of select="$string"/> </xsl:otherwise> </xsl:choose> </xsl:template>
