• What job title should be most suitable for my object in resume and what salary range should I expect

  - by user354177

  I was a classic asp developer in 2000. After a year of full-time employment, I left the field. I found a part-time position as an asp developer again in 2005 and taught myself vb.net. In 2007, I got the current full-time job as an Asp.net web developer. I taught myself C#, LING t0 SQL, Web Services, AJAX, and creating all kinds of reports with reporting services. One and half years ago, I sent myself to part-time graduate program in Database and Web Systems. I'll have two semesters to go and so far my GPA is 4.0/4.0. My job responsibility is to collect business requirements from other departments, design the database, write stored procedures, create aspx pages, and create reports. I love what I do and want to advance my career to the next level. What I enjoy most is to design the relational database. I would want to become an .Net Architect eventually. I got an interview. They were looking for asp.net web developer. But I was surprised and disappointed that position would only create aspx pages. I would not even have opportunity to write stored procedures, let alone design the database (those would be provided by another group). Furthermore, they asked me some detailed questions about web forms, some of which I did not know the answers. they might be disappointed as well. I am eager to learn and can apply what I learn to real projects right away. I believe no matter what specific skills I am lacking for a new position, I can catch up quickly. I am looking for $70k range job. The object in my resume is Experience C# Web Application Developer. Due to the experience from last interview, I wonder if the object is really what I want. Could somebody answer my questions? Thank you.

• Indexing data from multiple tables with Oracle Text

  - by Roger Ford

  It's well known that Oracle Text indexes perform best when all the data to be indexed is combined into a single index. The query select * from mytable where contains (title, 'dog') 0 or contains (body, 'cat') 0 will tend to perform much worse than select * from mytable where contains (text, 'dog WITHIN title OR cat WITHIN body') 0 For this reason, Oracle Text provides the MULTI_COLUMN_DATASTORE which will combine data from multiple columns into a single index. Effectively, it constructs a "virtual document" at indexing time, which might look something like: <title>the big dog</title> <body>the ginger cat smiles</body> This virtual document can be indexed using either AUTO_SECTION_GROUP, or by explicitly defining sections for title and body, allowing the query as expressed above. Note that we've used a column called "text" - this might have been a dummy column added to the table simply to allow us to create an index on it - or we could created the index on either of the "real" columns - title or body. It should be noted that MULTI_COLUMN_DATASTORE doesn't automatically handle updates to columns used by it - if you create the index on the column text, but specify that columns title and body are to be indexed, you will need to arrange triggers such that the text column is updated whenever title or body are altered. That works fine for single tables. But what if we actually want to combine data from multiple tables? In that case there are two approaches which work well: Create a real table which contains a summary of the information, and create the index on that using the MULTI_COLUMN_DATASTORE. This is simple, and effective, but it does use a lot of disk space as the information to be indexed has to be duplicated. Create our own "virtual" documents using the USER_DATASTORE. The user datastore allows us to specify a PL/SQL procedure which will be used to fetch the data to be indexed, returned in a CLOB, or occasionally in a BLOB or VARCHAR2. This PL/SQL procedure is called once for each row in the table to be indexed, and is passed the ROWID value of the current row being indexed. The actual contents of the procedure is entirely up to the owner, but it is normal to fetch data from one or more columns from database tables. In both cases, we still need to take care of updates - making sure that we have all the triggers necessary to update the indexed column (and, in case 1, the summary table) whenever any of the data to be indexed gets changed. I've written full examples of both these techniques, as SQL scripts to be run in the SQL*Plus tool. You will need to run them as a user who has CTXAPP role and CREATE DIRECTORY privilege. Part of the data to be indexed is a Microsoft Word file called "1.doc". You should create this file in Word, preferably containing the single line of text: "test document". This file can be saved anywhere, but the SQL scripts need to be changed so that the "create or replace directory" command refers to the right location. In the example, I've used C:\doc. multi_table_indexing_1.sql : creates a summary table containing all the data, and uses multi_column_datastore Download link / View in browser multi_table_indexing_2.sql : creates "virtual" documents using a procedure as a user_datastore Download link / View in browser

• Passing the CAML thru the EY of the NEEDL

  - by PointsToShare

  © 2011 By: Dov Trietsch. All rights reserved Passing the CAML thru the EY of the NEEDL Definitions: CAML (Collaborative Application Markup Language) is an XML based markup language used in Microsoft SharePoint technologies  Anonymous: A camel is a horse designed by committee  Dov Trietsch: A CAML is a HORS designed by Microsoft  I was advised against putting any Camel and Sphinx rhymes in here. Look it up in Google!  _____ Now that we have dispensed with the dromedary jokes (BTW, I have many more, but they are not fit to print!), here is an interesting problem and its solution.  We have built a list where the title must be kept unique so I needed to verify the existence (or absence) of a list item with a particular title. Two methods came to mind:  1: Span the list until the title is found (result = found) or until the list ends (result = not found). This is an algorithm of complexity O(N) and for long lists it is a performance sucker. 2: Use a CAML query instead. Here, for short list we’ll encounter some overhead, but because the query results in an SQL query on the content database, it is of complexity O(LogN), which is significantly better and scales perfectly. Obviously I decided to go with the latter and this is where the CAML s--t hit the fan.   A CAML query returns a SPListItemCollection and I simply checked its Count. If it was 0, the item did not already exist and it was safe to add a new item with the given title. Otherwise I cancelled the operation and warned the user. The trouble was that I always got a positive. Most of the time a false positive. The count was greater than 0 regardles of the title I checked (except when the list was empty, which happens only once). This was very disturbing indeed. To solve my immediate problem which was speedy delivery, I reverted to the “Span the list” approach, but the problem bugged me, so I wrote a little console app by which I tested and tweaked and tested, time and again, until I found the solution. Yes, one can pass the proverbial CAML thru the ey of the needle (e’s missing on purpose).  So here are my conclusions:  CAML that does not work:  Note: QT is my quote:  char QT = Convert.ToChar((int)34); string titleQuery = "<Query>><Where><Eq>"; titleQuery += "<FieldRef Name=" + QT + "Title" + QT + "/>"; titleQuery += "<Value Type=" + QT + "Text" + QT + ">" + uniqueID + "</Value></Eq></Where></Query>"; titleQuery += "<ViewFields><FieldRef Name=" + QT + "Title" + QT + "/></ViewFields>";  Why? Even though U2U generates it, the <Query> and </Query> tags do not belong in the query that you pass. Start your query with the <Where> clause.  Also the <ViewFiels> clause does not belong. I used this clause to limit the returned collection to a single column, and I still wish to do it. I’ll show how this is done a bit later.   When you use the <Query> </Query> tags in you query, it’s as if you did not specify the query at all. What you get is the all inclusive default query for the list. It returns evey column and every item. It is expensive for both server and network because it does all the extra processing and eats plenty of bandwidth.   Now, here is the CAML that works  string titleQuery = "<Where><Eq>"; titleQuery += "<FieldRef Name=" + QT + "Title" + QT + "/>"; titleQuery += "<Value Type=" + QT + "Text" + QT + ">" + uniqueID + "</Value></Eq></Where>";  You’ll also notice that inside the unusable <ViewFields> clause above, we have a <FieldRef> clause. This is what we pass to the SPQuery object. Here is how:  SPQuery query = new SPQuery(); query.Query = titleQuery; query.ViewFields = "<FieldRef Name=" + QT + "Title" + QT + "/>"; query.RowLimit = 1; SPListItemCollection col = masterList.GetItems(query);  Two thing to note: we enter the view fields into the SPQuery object and we also limited the number of rows that the query returns. The latter is not always done, but in an existence test, there is no point in returning hundreds of rows. The query will now return one item or none, which is all we need in order to verify the existence (or non-existence) of items. Limiting the number of columns and the number of rows is a great performance enhancer. That’s all folks!!

• Extended FindWindow

  - by João Angelo

  The Win32 API provides the FindWindow function that supports finding top-level windows by their class name and/or title. However, the title search does not work if you are trying to match partial text at the middle or the end of the full window title. You can however implement support for these extended search features by using another set of Win32 API like EnumWindows and GetWindowText. A possible implementation follows: using System; using System.Collections.Generic; using System.Linq; using System.Runtime.InteropServices; using System.Text; public class WindowInfo { private IntPtr handle; private string className; internal WindowInfo(IntPtr handle, string title) { if (handle == IntPtr.Zero) throw new ArgumentException("Invalid handle.", "handle"); this.Handle = handle; this.Title = title ?? string.Empty; } public string Title { get; private set; } public string ClassName { get { if (className == null) { className = GetWindowClassNameByHandle(this.Handle); } return className; } } public IntPtr Handle { get { if (!NativeMethods.IsWindow(this.handle)) throw new InvalidOperationException("The handle is no longer valid."); return this.handle; } private set { this.handle = value; } } public static WindowInfo[] EnumerateWindows() { var windows = new List<WindowInfo>(); NativeMethods.EnumWindowsProcessor processor = (hwnd, lParam) => { windows.Add(new WindowInfo(hwnd, GetWindowTextByHandle(hwnd))); return true; }; bool succeeded = NativeMethods.EnumWindows(processor, IntPtr.Zero); if (!succeeded) return new WindowInfo[] { }; return windows.ToArray(); } public static WindowInfo FindWindow(Predicate<WindowInfo> predicate) { WindowInfo target = null; NativeMethods.EnumWindowsProcessor processor = (hwnd, lParam) => { var current = new WindowInfo(hwnd, GetWindowTextByHandle(hwnd)); if (predicate(current)) { target = current; return false; } return true; }; NativeMethods.EnumWindows(processor, IntPtr.Zero); return target; } private static string GetWindowTextByHandle(IntPtr handle) { if (handle == IntPtr.Zero) throw new ArgumentException("Invalid handle.", "handle"); int length = NativeMethods.GetWindowTextLength(handle); if (length == 0) return string.Empty; var buffer = new StringBuilder(length + 1); NativeMethods.GetWindowText(handle, buffer, buffer.Capacity); return buffer.ToString(); } private static string GetWindowClassNameByHandle(IntPtr handle) { if (handle == IntPtr.Zero) throw new ArgumentException("Invalid handle.", "handle"); const int WindowClassNameMaxLength = 256; var buffer = new StringBuilder(WindowClassNameMaxLength); NativeMethods.GetClassName(handle, buffer, buffer.Capacity); return buffer.ToString(); } } internal class NativeMethods { public delegate bool EnumWindowsProcessor(IntPtr hwnd, IntPtr lParam); [DllImport("user32.dll")] [return: MarshalAs(UnmanagedType.Bool)] public static extern bool EnumWindows( EnumWindowsProcessor lpEnumFunc, IntPtr lParam); [DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)] public static extern int GetWindowText( IntPtr hWnd, StringBuilder lpString, int nMaxCount); [DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)] public static extern int GetWindowTextLength(IntPtr hWnd); [DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)] public static extern int GetClassName( IntPtr hWnd, StringBuilder lpClassName, int nMaxCount); [DllImport("user32.dll")] [return: MarshalAs(UnmanagedType.Bool)] public static extern bool IsWindow(IntPtr hWnd); } The access to the windows handle is preceded by a sanity check to assert if it’s still valid, but if you are dealing with windows out of your control then the window can be destroyed right after the check so it’s not guaranteed that you’ll get a valid handle. Finally, to wrap this up a usage, example: static void Main(string[] args) { var w = WindowInfo.FindWindow(wi => wi.Title.Contains("Test.docx")); if (w != null) { Console.Write(w.Title); } }

• Reading non-standard elements in a SyndicationItem with SyndicationFeed

  - by Jared

  With .net 3.5, there is a SyndicationFeed that will load in a RSS feed and allow you to run LINQ on it. Here is an example of the RSS that I am loading: <rss version="2.0" xmlns:media="http://search.yahoo.com/mrss/"> <channel> <title>Title of RSS feed</title> <link>http://www.google.com</link> <description>Details about the feed</description> <pubDate>Mon, 24 Nov 08 21:44:21 -0500</pubDate> <language>en</language> <item> <title>Article 1</title> <description><![CDATA[How to use StackOverflow.com]]></description> <link>http://youtube.com/?v=y6_-cLWwEU0</link> <media:player url="http://youtube.com/?v=y6_-cLWwEU0" /> <media:thumbnail url="http://img.youtube.com/vi/y6_-cLWwEU0/default.jpg" width="120" height="90" /> <media:title>Jared on StackOverflow</media:title> <media:category label="Tags">tag1, tag2</media:category> <media:credit>Jared</media:credit> <enclosure url="http://youtube.com/v/y6_-cLWwEU0.swf" length="233" type="application/x-shockwave-flash"/> </item> </channel> When I loop through the items, I can get back the title and the link through the public properties of SyndicationItem. I can't seem to figure out how to get the attributes of the enclosure tag, or the values of the media tags. I tried using SyndicationItem.ElementExtensions.ReadElementExtensions<string>("player", "http://search.yahoo.com/mrss/") Any help with either of these?

• OData / WCF Data Service - HTTP 500 Error

  - by Eric

  I have created an OData/WCF service using Visual Studio 2010 on Windows XP SP3 with all current patches installed. When I click on "view in browser", the service opens and I see the 3 tables from my EF model. However, when I add a table name ("Commands" in this case) to the end of the query string, rather than seeing the data from the table, I get an HTTP 500 error. (This error (HTTP 500 Internal Server Error) means that the website you are visiting had a server problem which prevented the webpage from displaying.). I have not only followed the examples from 2 sites, but have also tried running the sample application that the blog poster sent me (that works on his machine), and still am not having any luck. The blog post is at Exposing OData from an Entity Framework Model Does anyone have an idea why this is occurring and how to resolve it? Here is the output of the "View in Browser": <?xml version="1.0" encoding="utf-8" standalone="yes" ?> - <service xml:base="http://localhost:1883/VistaDBCommandService.svc/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:app="http://www.w3.org/2007/app" xmlns="http://www.w3.org/2007/app"> - <workspace> <atom:title>Default</atom:title> - <collection href="Commands"> <atom:title>Commands</atom:title> </collection> - <collection href="Databases"> <atom:title>Databases</atom:title> </collection> - <collection href="Statuses"> <atom:title>Statuses</atom:title> </collection> </workspace> </service> ============================= Thanks, Eric

• C# Inheritence: Choosing what repository based on type of inherited class

  - by Oskar Kjellin

  I have been making a program that downloads information about movies from the internet. I have a base class Title, which represents all titles. Movie, Serie and Episode are inherited from that class. To save them to the database I have 2 services, MovieService and SerieService. They in turn call repositories, but that is not important here. I have a method Save(Title title) which I am not very happy with. I check for what type the title is and then call the correct service. I would like to perhaps write like this: ITitleService service = title.GetService(); title.GetSavedBy(service); So I have an abstract method on Title that returns an ITitleSaver, which will return the correct service for the instance. My question is how should I implement ITitleSaver? If I make it accept Title I will have to cast it to the correct type before calling the correct overload. Which will lead to having to deal with casting once again. What is the best approach to dealing with this? I would like to have the saving logic in the corresponding class.

• HTML/CSS issue with a:hover and spans

  - by Tribalcomm

  Any way I can get this working? I have a block of code: <p><a href="http://foo.com"><span class="title">Title</span><br /><br /> Some text no greater than a couple of lines...</a></p> My styles are: p {color:#FFF;} a {color:#999;} .title {color:#FFF; font-weight:bold;} a:hover {color:#FF0;} My problem is as follows: I want the title to be white and bold and the body to be gray, but when you hover over any part, I want the title AND text to become yellow. However, in the above scenario, only the text becomes yellow because the span color (white) overrides the a:hover. If I add: .title:hover {color:#FF0;} then the title color only changes if I specifically hover over the title. It also doesn't change the text to yellow, as it is now a span hover... Any way I can resolve this, even if it requires a little JS? Thanks!

• How to customize RESTful Routes in Rails (basics)

  - by viatropos

  I have read through the Rails docs for Routing, Restful Resources, and the UrlHelper, and still don't understand best practices for creating complex/nested routes. The example I'm working on now is for events, which has_many rsvps. So a user's looking through a list of events, and clicks register, and goes through a registration process, etc. I want the urls to look like this: /events /events/123 # possible without title, like SO /events/123/my-event-title # canonical version /events/my-category/123/my-event-title # also possible like this /events/123/my-event-title/registration/new ... and all the restful nested resouces. Question is, how do I accomplish this with the minimal amount of code? Here's what I currently have: map.resources :events do |event| event.resources :rsvps, :as => "registration" end That gets me this: /events/123/registration What's the best way to accomplish the other 2 routes? /events/123/my-event-title # canonical version /events/my-category/123/my-event-title # also possible like this Where my-category is just an array of 10 possible types the event can be. I've modified Event#to_param to return "#{self.id.to_s}-#{self.title.parameterize}", but I'd prefer to have /id/title with the whole canonical-ness

• "string" != "string"

  - by Misiur

  Hi. I'm doing some kind of own templates system. I want to change <title>{site('title')}</title> Into function "site" execution with parameter "title". Here's private function replaceFunc($subject) { foreach($this->func as $t) { $args = explode(", ", preg_replace('/\{'.$t.'\(\'([a-zA-Z,]+)\'\)\}/', '$1', $subject)); $subject = preg_replace('/\{'.$t.'\([a-zA-Z,\']+\)\}/', call_user_func_array($t, $args), $subject); } return $subject; } Here's site: function site($what) { global $db; $s = $db->askSingle("SELECT * FROM ".DB_PREFIX."config"); switch($what) { case 'title': return 'Title of page'; break; case 'version': return $s->version; break; case 'themeDir': return 'lolmao'; break; default: return false; } } I've tried to compare $what (which is for this case "title") with "title". MD5 are different. strcmp gives -1, "==", and "===" return false. What is wrong? ($what type is string. You can't change call_user_func_array into call_user_func, because later I'll be using multiple arguments)

  I'm making an script to automatically create plots from .xvg files, but there's a problem when I'm trying to use pylab's savefig() method. Using pylab.show() and saving from there, everything's fine. Using pylab.show() Using pylab.savefig() def producePlot(timestep, energy_values,type_line = 'r', jump = 1,finish = 100): fc = sp.interp1d(timestep[::jump], energy_values[::jump],kind='cubic') xnew = numpy.linspace(0, finish, finish*2) pylab.plot(xnew, fc(xnew),type_line) pylab.xlabel('Time in ps ') pylab.ylabel('kJ/mol') pylab.xlim(xmin=0, xmax=finish) def produceSimplePlot(timestep, energy_values,type_line = 'r', jump = 1,finish = 100): pylab.plot(timestep, energy_values,type_line) pylab.xlabel('Time in ps ') pylab.ylabel('kJ/mol') pylab.xlim(xmin=0, xmax=finish) def linearRegression(timestep, energy_values, type_line = 'g'): #, jump = 1,finish = 100): from scipy import stats import numpy #print 'fuck' timestep = numpy.asarray(timestep) slope, intercept, r_value, p_value, std_err = stats.linregress(timestep,energy_values) line = slope*timestep+intercept pylab.plot(timestep, line, type_line) def plottingTime(Title,file_name, timestep, energy_values ,loc, jump , finish): pylab.title(Title) producePlot(timestep,energy_values, 'b',jump, finish) linearRegression(timestep,energy_values) import numpy Average = numpy.average(energy_values) #print Average pylab.legend(("Average = %.2f" %(Average),'Linear Reg'),loc) #pylab.show() pylab.savefig('%s.jpg' %file_name[:-4], bbox_inches= None, pad_inches=0) #if __name__ == '__main__': #plottingTime(Title,timestep1, energy_values, jump =10, finish = 4800) def specialCase(Title,file_name, timestep, energy_values,loc, jump, finish): #print 'Working here ...?' pylab.title(Title) producePlot(timestep,energy_values, 'b',jump, finish) import numpy from pylab import * Average = numpy.average(energy_values) #print Average pylab.legend(("Average = %.2g" %(Average), Title),loc) locs,labels = yticks() yticks(locs, map(lambda x: "%.3g" % x, locs)) #pylab.show() pylab.savefig('%s.jpg' %file_name[:-4] , bbox_inches= None, pad_inches=0) Thanks in advance, John

• Add delay and focus for a dead simple accordion jquery

  - by kuswantin

  I found the code somewhere in the world, and due to its dead simple nature, I found some things in need to fix, like when hovering the trigger, the content is jumping up down before it settled. I have tried to change the trigger from the title of the accordion block to the whole accordion block to no use. I need help to add a delay and only do the accordion when the cursor is focus in the block. I have corrected my css to make sure the block is covering the hidden part as well when toggled. Here is my latest modified code: var acTrig = ".accordion .title"; $(acTrig).hover(function() { $(".accordion .content").slideUp("normal"); $(this).next(".content").slideDown("normal"); }); $(acTrig).next(".content").hide(); $(acTrig).next(".content").eq(0).css('display', 'block'); This is the HTML: <div class="accordion clearfix"> <div class="title">some Title 1</div> <div class="content"> some content blah </div> </div> <div class="accordion clearfix"> <div class="title">some Title 2</div> <div class="content"> some content blah </div> </div> <div class="accordion clearfix"> <div class="title">some Title 3</div> <div class="content"> some content blah </div> </div> I think I need a way to stop event bubbling somewhere around the code, but can't get it right. Any help would be very much appreciated. Thanks as always.

• Using Scala and StringTemplate, how do I loop through a Map

  - by Marcus Kazmierczak

  I have my environment setup nicely using Scala, StringTempalte within the Google AppEngine. I am having trouble looping through a Map and getting it to display in the template. When I assign a simple List of just Strings to the template it works using: In Scala Servlet: var photos = List[String]() //... get photo url and title ... photos = photo_url :: photos template.setAttribute("photos", photos: _*) In Template: $photos: { photo| <div><img src="$photo$_s.jpg"></div> }$ The above works. However, any attempt of creating a Map using url and title and assigning to the template gives me an error. Here is my attempt, which does not work: In Scala Servlet: var photos = List[Map[String,String]]() //... get photo url and title ... photos = Map("url" -> url, "title" -> title) :: photos template.setAttribute("photos", photos: _*) In Template: $photos: { photo| <div><img src="$photo.url$_s.jpg" title="$photo.title$"></div> }$ This gives me the following error Class scala.collection.immutable.Map$Map2 has no such attribute: title in template context Thoughts / Ideas ?

• png image blurry when loaded onto texture

  I have created a png image in photoshop with transparencies that I have loaded into and OpenGL program. I have binded it to a texture and in the program the picture looks blurry and I'm not sure why. Loading Code // Texture loading object nv::Image title; // Return true on success if(title.loadImageFromFile("test.png")) { glGenTextures(1, &titleTex); glBindTexture(GL_TEXTURE_2D, titleTex); glTexParameteri(GL_TEXTURE_2D, GL_GENERATE_MIPMAP, GL_TRUE); glTexImage2D(GL_TEXTURE_2D, 0, title.getInternalFormat(), title.getWidth(), title.getHeight(), 0, title.getFormat(), title.getType(), title.getLevel(0)); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAX_ANISOTROPY_EXT, 16.0f); } else MessageBox(NULL, "Failed to load texture", "End of the world", MB_OK | MB_ICONINFORMATION); Display Code glEnable(GL_TEXTURE_2D); glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glBindTexture(GL_TEXTURE_2D, titleTex); glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE); glTranslatef(-800, 0, 0.0); glColor3f(1,1,1); glBegin(GL_QUADS); glTexCoord2f(0.0, 0.0); glVertex2f(0,0); glTexCoord2f(0.0, 1.0); glVertex2f(0,600); glTexCoord2f(1.0, 1.0); glVertex2f(1600,600); glTexCoord2f(1.0, 0.0); glVertex2f(1600,0); glEnd(); glDisable(GL_BLEND); glDisable(GL_TEXTURE_2D);

• AddEvenLister fires off immediately after being attached

  - by Diego

  I want to know how to correctly add an Event Listener like onClick to a dynamic div. Here’s my snippet: var $menu = new Array(2); createDiv('yes'); function createDiv(title) { var $class = 'menuLink'; var $title = 'title'; for(var i=0; i<$menu.length;i++) { $title = 'title'; var newdiv = document.createElement('div'); newdiv.setAttribute('class', $class); newdiv.setAttribute('id', 'item'+i); newdiv.addEventListener('onclick', clickHandle(newdiv.id),false); if (title) { newdiv.innerHTML = $title; } else { newdiv.innerHTML = "No Title"; } document.getElementById('menu').appendChild(newdiv); showMenu(); } } function clickHandle(e) { if(e == 'item0') { alert('Link is' + ' ' + e); }else{ alert('Another Link'); } } Here's my problem, the snippet works fine, It creates my divs, adds id's values and all, but the event fires off as soon as the event is attached, so while the for loop is creating the divs the alert window says: Link is item0, and immediately after this it says: Another Link. Am I misunderstanding this? (I used this method zillions of times in AS3 with the expected result, just attached a function waiting for a click). What I want is that my Divs wait for the user to click on them, not to fire off immediately after of being attached. Thanks for any hint on this one. Greetings. Ps. IE doesn't support addEventListener, but I want to resolve this before cross to the IE sea of madness, but I will appreciate the IE approach as well. - I tried "onclick" and just 'click' into the addEventListener line, both with the same result described above.

• Idiomatic PHP web page creation

  - by GreenMatt

  My PHP experience is rather limited. I've just inherited some stuff that looks odd to me, and I'd like to know if this is a standard way to do things. The page which shows up in the browser location (e.g. www.example.com/example_page) has something like: <? $title = "Page Title"; $meta = "Some metadata"; require("pageheader.inc"); ?> <!-- Content --> Then pageheader.inc has stuff like: <? @$title = ($title) ? $title : ""; @$meta = ($meta) ? $meta : ""; ?> <html> <head> <title><?=$title?></title </head> <!-- and so forth --> Maybe others find this style useful, but it confuses me. I suppose this could be a step toward a rudimentary content management system, but the way it works here I'd think it adds to the processing the server has to do without reducing the load on the web developer enough to make it worth the effort. So, is this a normal way to create pages with PHP? Or should I pull all this in favor of a better approach? Also, I know that "<?" (vs. "<?php" ) is undesirable; I'm just reproducing what is in the code.

• many to many and integrity when saving the null

  - by user369759

  I have two classes Software, Tag - they are related by ManyToMany. We CAN NOT create Software without putting the Tag to it. I want to write a test which check that: @Test public void createSoftwareWithNullTags() { List<Tag> tags = null; Software software = new Software("software1", "description1", tags); try { software.save(); fail("tags should not be null"); } catch (Exception ex) { // NEVER COME HERE !!! } } So, this test fails. I guess it is not good test for that case - because it even do not try to SAVE data to SOFTWARE_TAG table. Of course i could do validation manually but i want implement it with hibernate, using some annotation or something. Is it possible? Or how would you do this? My entities: @Entity public class Tag extends Model { public String title; public Tag(String title) { this.title = title; } @ManyToMany( cascade = {CascadeType.ALL}, mappedBy = "tags", targetEntity = Software.class ) public List<Software> softwares; } @Entity public class Software extends Model { public String title; public String description; @ManyToOne(optional = false) public Author author; @ManyToMany(cascade = CascadeType.ALL) @JoinTable( name = "SOFTWARE_TAG", joinColumns = @JoinColumn(name = "Software_id"), inverseJoinColumns = @JoinColumn(name = "Tag_id") ) public List<Tag> tags; public Software(String title, String description, Author author, List<Tag> tags) { this.title = title; this.description = description; this.author = author; this.tags = tags; } }

• Ruby syntax error: unexpected $end, expecting keyword_end

  - by user2839246

  I am supposed to: Capitalize the first letter of string. Capitalize every word except articles (the, a, an), conjunctions (and), and prepositions (in). Capitalize i (as in "I am male."). Specify the first word of a string (I actually have no idea what this means. I'm trying to run the spec file to test other functions). Here's my code: class Book def initialize(string) title(string) end def title(string) arts_conjs_preps = %w{ a an the and but or nor for yet so although because since unless despite in to } array = string.downcase.split array.each do |word| if (word == array[0] || word == "i") then word = word.capitalize if arts_conjs_preps !include?(word) then word = word.capitalize end puts array.join(' ') end end puts Book.new("inferno") Ruby says I'm messing up at: puts Book.new("inferno") <--(right after the last line of code) I get exactly the same error message with this test code: def title(string) array = string.downcase.split array.each do |word| if word == array[0] then word = word.capitalize end array.join(' ') end puts title("dante's inferno") The only other Stack Overflow thread regarding this particular syntax error that did not suggest trailing or missing ends or .s as the root of the problem is here. The last comment recommends deleting and recreating the gemset, Which sounds scary. And I'm not sure how to do. Any thoughts? Simple solution? Resources to help? Solution class Book def initialize(string) title(string) end def title(string) arts_conjs_preps = %w{ a an the and but or nor for yet so although because since unless despite of in to } array = string.downcase.split title = array.map do |word| if (word == array[0] || word == "i") || !arts_conjs_preps.include?(word) word = word.capitalize else word end end puts title.join(' ') end end Book.new("dante's the inferno")
