• Good data structure for efficient insert/querying on arbitrary properties

  - by Juliet

  I'm working on a project where Arrays are the default data structure for everything, and every query is a linear search in the form of: Need a customer with a particular name? customer.Find(x => x.Name == name) Need a customer with a particular unique id? customer.Find(x => x.Id == id) Need a customer of a particular type and age? customer.Find(x => x is PreferredCustomer && x.Age >= age) Need a customer of a particular name and age? customer.Find(x => x.Name == name && x.Age == age) In almost all instances, the criteria for lookups is well-defined. For example, we only search for customers by one or more of the properties Id, Type, Name, or Age. We rarely search by anything else. Is a good data structure to support arbitrary queries of these types with lookup better than O(n)? Any out-of-the-box implementations for .NET?

• How to avoid CSS conflict using jquery?

  - by user2885137

  I am experiencing a CSS conflict issue. Here are the details: I have a search results page in which products are shown in grid format. The CSS for that is grid search results is "product-grid.css" which is included header of the page. On this page I have button which when clicked shows the search results in list format. The css for list format is "product-list.css" which is also included in head tag of the page. Now the HTML guy has made the name of classes to be same in both product-grid.css and product-list.css. What I want is that when I am viewing the page in grid style only product-grid.css should apply to respective portion of the page. And when I am viewing the page in list format then product-grid.css should be disabled and product-list.css should apply on whole page. I have tried enabling and disabling css files using jquery but may be I am doing something wrong. Also when the page loads both css files are active in head tag and due to conflict in classes names the page is malformed even without shifting to other view. Any help what should I do?

  - by Harish Kurup

  I am using Ajax POST method to send data, but i am not able to send '+'(operator to the server i.e if i want to send 1+ or 20k+ it will only send 1 or 20k..just wipe out '+') HTML code goes here.. <form method='post' onsubmit='return false;' action='#'> <input type='input' name='salary' id='salary' /> <input type='submit' onclick='submitVal();' /> </form> and javascript code goes here, function submitVal() { var sal=document.getElementById("salary").value; alert(sal); var request=getHttpRequest(); request.open('post','updateSal.php',false); request.setRequestHeader("Content-Type","application/x-www-form-urlencoded"); request.send("sal="+sal); if(request.readyState == 4) { alert("update"); } } function getHttpRequest() { var request=false; if(window.XMLHttpRequest) { request=new XMLHttpRequest(); } else if(window.ActiveXObject) { try { request=new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { try { request=new ActiveXObject("Microsoft.XMLHTTP"); } catch(e) { request=false; } } } return request; } in the function submitVal() it first alert's the salary value as it is(if 1+ then alerts 1+), but when it is posted it just post's value without '+' operator which is needed... is it any problem with query string, as the PHP backend code is working fine...

• doubt in javascript name validation

  - by raja

  Hi: I am using the below validation for textbox which accepts only alphabets and maximum of 50 characters. I am passing the object directly in the parameter. The below case by giving the field name i.e "my_text" directly is working is working fine. But if i pass it in variable, that time it is not working(commented the if statement). Please help me. My requirement is each time when we enter the charater, the hardcode field name should not be used in the validation. <html><head> <script language=JavaScript> function check_length(my_form,fieldName) { alert(fieldName); // if (my_form.fieldName.value.length >= maxLen) { if (my_form.my_text.value.length >= maxLen) { var msg = "You have reached your maximum limit of characters allowed"; alert(msg); my_form.my_text.value = my_form.my_text.value.substring(0, maxLen); } else{ var keyCode = window.event.keyCode; if ((keyCode < 65 || keyCode > 90) && (keyCode < 97 || keyCode > 123) && keyCode != 32) { window.event.returnValue = false; alert("Enter only Alphabets"); } my_form.text_num.value = maxLen - my_form.my_text.value.length;} } </script> </head> <body> <form name=my_form method=post> <input type="text" onKeyPress=check_length(this.form,this.name); name=my_text rows=4 cols=30> <br> <input size=1 value=50 name=text_num> Characters Left </form> </body> </html>

• I dont know how or where to add the correct encoding code to this iPhone code...

  - by BC

  Ok, I understand that using strings that have special characters is an encoding issue. However I am not sure how to adjust my code to allow these characters. Below is the code that works great for text that contains no special characters, but can you show me how and where to change the code to allow for the special characters to be used. Right now those characters crash the app. enter code here - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{ if (buttonIndex == 1) { //iTunes Audio Search NSString *stringURL = [NSString stringWithFormat:@"http://phobos.apple.com/WebObjects/MZSearch.woa/wa/search?WOURLEncoding=ISO8859_1&lang=1&output=lm&term=\"%@\"",currentSong.title]; stringURL = [stringURL stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding]; NSURL *url = [NSURL URLWithString:stringURL]; [[UIApplication sharedApplication] openURL:url]; } } And this: -(IBAction)launchLyricsSearch:(id)sender{ WebViewController * webView = [[WebViewController alloc] initWithNibName:@"WebViewController" bundle:[NSBundle mainBundle]]; webView.webURL = [NSString stringWithFormat:@"http://www.google.com/m/search?hl=es&q=\"%@\"+letras",currentSong.title]; webView.webTitle = @"Letras"; [self.navigationController pushViewController:webView animated:YES]; } Please show me how and where to do this for these two bits of code.

• RSpec: Can't convert Image to String when using Nested Resource.

  - by darrint

  I'm having trouble with and RSpec view test. I'm using nested resources and the model with a belongs_to association. Here's what I have so far: describe "/images/edit.html.erb" do include ImagesHelper before(:each) do @image_pool = stub_model(ImagePool, :new_record => false, :base_path => '/') assigns[:image] = @image = stub_model(Image, :new_record? => false, :source_name => "value for source_name", :image_pool => @image_pool) end it "renders the edit image form" do render response.should have_tag("form[action=#{image_path(@image)}][method=post]") do with_tag('input#image_source_name[name=?]', "image[source_name]") end end end The error I'm receiving: ActionView::TemplateError in '/images/edit.html.erb renders the edit image form' can't convert Image into String On line #3 of app/views/images/edit.html.erb 1: <h1>Editing image</h1> 2: 3: <% form_for(@image) do |f| %> 4: <%= f.error_messages %> 5: 6: <p> app/views/images/edit.html.erb:3 /opt/dtcm/railstest/lib/ruby/gems/1.9.1/gems/rspec-rails-1.3.2/lib/spec/rails/extensions/action_view/base.rb:27:in `render_with_mock_proxy' /opt/dtcm/railstest/lib/ruby/gems/1.9.1/gems/rspec-rails-1.3.2/lib/spec/rails/example/view_example_group.rb:170:in `render' Looking at the rails code where the exception occurs is not very revealing. Any ideas on how I can narrow down what is going on here? One thing I tried was calling form_for directly from the example and I got a different error griping about lack of 'polymorphic_path' defined on Spec::Rails::Example::ViewExampleGroup::Subclass_4:0xblah. Not sure if that actually means anything.

• Google Maps InfoBubble pixelOffset

  - by Sam

  I am trying to implement a custom infoBubble that has the box opening to the side of a marker. This has turned out to be harder than expected. Using the normal infoWindow you can use pixelOffset. See here for the documentation Using infoBubble this does not seem to be the case. Is there anyway of using pixelOffset in an infoBubble, or something that will do the same thing? I have found this very difficult to search for, as using a google search such as this returns no relevant results Google Search Below is all my resources I have been using. Example of infoBubble here. My JavaScript to setup the map and infoBubble here. And now my javascript here just in-case the jsfiddle link is broken. <script type="text/javascript"> $(document).ready(function () { init(); }); function init() { //Setup the map var googleMapOptions = { center: new google.maps.LatLng(53.5167, -1.1333), zoom: 13, mapTypeId: google.maps.MapTypeId.ROADMAP }; //Start the map var map = new google.maps.Map(document.getElementById("map_canvas"), googleMapOptions); var marker = new google.maps.Marker({ position: new google.maps.LatLng(53.5267, -1.1333), title: "Just a test" }); marker.setMap(map); infoBubble = new InfoBubble({ map: map, content: '<div class="phoneytext">Some label</div>', //position: new google.maps.LatLng(-35, 151), shadowStyle: 1, padding: '10px', //backgroundColor: 'rgb(57,57,57)', borderRadius: 5, minWidth: 200, arrowSize: 10, borderWidth: 1, borderColor: '#2c2c2c', disableAutoPan: true, hideCloseButton: false, arrowPosition: 7, backgroundClassName: 'phoney', pixelOffset: new google.maps.Size(130, 120), arrowStyle: 2 }); infoBubble.open(map, marker); } </script>

• Return latitude/longitude based on entered address

  - by Don

  I'm building a php based application for a client to enter in addresses for their customers' buildings. They'd like the ability to view the location on a map (either as individuals or grouped in a city search). What I'm trying to accomplish is a lookup once the address is entered into a form that populates the database, so after they enter in the addresss, city, state, zip (these are all US locations) they could click a "get lat/long info" link/button that would check to make sure the data is complete, then would lookup the address and return the latitude/longitude into the appropriate form fields. Then the form could be submitted to store the info, and I could later just pull the lat/long when plotting on a map. 1) Does this make sense, or would I be better off just doing the lookup when it's time to plot it? 2) Does anyone have any pointers to solve this problem? I've seen some of the Google/Yahoo API's but it looks like this is more based on the plotting a point part. I may be able to modify it to suit my needs, but I'm just trying to cut some research time posting here with the hopes one of you may have a more direct route. I'll RTFM if I have to... Thanks, D.

• prolog - infinite rule

  - by Tom

  I have the next rules % Signature: natural_number(N)/1 % Purpose: N is a natural number. natural_number(0). natural_number(s(X)) :- natural_number(X) ackermann(0, N, s(N)). //rule 1 ackermann(s(M),0,Result):- ackermann(M,s(0),Result). //rule 2 ackermann(s(M),s(N),Result):-ackermann(M,Result1,Result),ackermann(s(M),N,Result1). //rule 3 The query is: ackermann (M,N,s(s(0))). Now, as I understood, In the third calculation, we got an infinite search (failture branch). I check it, and I got a finite search (failture branch). I'll explain: In the first, we got a substitue of M=0, N=s(0) (rule 1 - succsess!). In the second, we got a substitue of M=s(0),N=0 (rule 2 - sucsses!). But what now? I try to match M=s(s(0)) N=0, But it got a finite search - failture branch. Why the comipler doesn't write me "fail". Thank you.

• Uploading a file fails under WordPress

  - by Ash

  I'm using WordPress and I'm following W3's guide for uploading a file: HTML code: <html> <body> <form action="upload_file.php" method="post" enctype="multipart/form-data"> <label for="file">Filename:</label> <input type="file" name="file" id="file" /> <br /> <input type="submit" name="submit" value="Submit" /> </form> </body> </html> PHP code (upload_file.php): <?php if ($_FILES["file"]["error"] > 0) { echo "Error: " . $_FILES["file"]["error"] . "<br />"; } else { echo "Upload: " . $_FILES["file"]["name"] . "<br />"; echo "Type: " . $_FILES["file"]["type"] . "<br />"; echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />"; echo "Stored in: " . $_FILES["file"]["tmp_name"]; } ?> The HTML code is pasted in a PHP page template and the PHP file under the WP installation directory under www. The problem is when I submit the file I get Error: 1. If I remark the "if" part of the PHP code and leave the "else" part I get: Upload: IMG_4258.JPG Type: Size: 0 Kb Stored in: So at least I know the PHP code is running. But what's causing it to fail? Is there a problem with the code or is WordPress meddling with the process?

• Java object graph -> xml when direction of object association needs to be reversed.

  - by Sigmoidal

  An application I have been working on has objects with a relationship similar to below. In the real application both objects are JPA entities. class Underlying{} class Thing { private Underlying underlying; public Underlying getUnderlying() { return underlying; } public void setUnderlying(final Underlying underlying) { this.underlying = underlying; } } There is a requirement in the application to create xml of the form: <template> <underlying> <thing/> <thing/> <thing/> </underlying> </template> So we have a situation where the object graph expresses the relationship between Thing and Underlying in the opposite direction to how it's expressed in the xml. I expect to use JAXB to create the xml but ideally I don't want to have to create a new object hierarchy to reflect the associations in the xml. Is there any way to create xml of the form required from the entities in their current form (through the use of xml annotations or something)? I don't have any experience using JAXB but from the limited research I've done it doesn't seem like it's possible to reverse the direction of association in any straightforward way. Any help/advice would be greatly appreciated. One other option that has been suggested is to use XLST to transform the xml into the correct format. I have done no research on this topic as yet but I'll add to the question when I have some more info. Thanks, Matt.

• Is it a good idea to use MySQL and Neo4j together?

  - by Sanoj

  I will make an application with a lot of similar items (millions), and I would like to store them in a MySQL database, because I would like to do a lot of statistics and search on specific values for specific columns. But at the same time, I will store relations between all the items, that are related in many connected binary-tree-like structures (transitive closure), and relation databases are not good at that kind of structures, so I would like to store all relations in Neo4j which have good performance for this kind of data. My plan is to have all data except the relations in the MySQL database and all relations with item_id stored in the Neo4j database. When I want to lookup a tree, I first search the Neo4j for all the item_id:s in the tree, then I search the MySQL-database for all the specified items in a query that would look like: SELECT * FROM items WHERE item_id = 45 OR item_id = 345435 OR item_id = 343 OR item_id = 78 OR item_id = 4522 OR item_id = 676 OR item_id = 443 OR item_id = 4255 OR item_id = 4345 Is this a good idea, or am I very wrong? I haven't used graph-databases before. Are there any better approaches to my problem? How would the MySQL-query perform in this case?

• iTextSharp Overlay Image

  - by pennylane

  Hi guys I have an instance where I have a logo image as part of some artwork.. If a user uploads a new logo I have a form field which is larger than the default logo. I then use that form field to position the new image. The problem is I need to set the background colour of that form field to white so that it covers the old logo in the event that the new image is smaller than the old logo.. what I have done is: foreach (var imageField in imageReplacements) { fields.SetFieldProperty(imageField.Key, "bgcolor", iTextSharp.text.Color.WHITE, null); fields.RegenerateField(imageField.Key); PdfContentByte overContent = stamper.GetOverContent(imageField.Value.PageNumber); float[] logoArea = fields.GetFieldPositions(imageField.Key); if (logoArea != null) { iTextSharp.text.Rectangle logoRect = new iTextSharp.text.Rectangle(logoArea[1], logoArea[2], logoArea[3], logoArea[4]); var logo = iTextSharp.text.Image.GetInstance(imageField.Value.Location); if (logo.Width >= logoRect.Width || logo.Height >= logoRect.Height) { logo.ScaleToFit(logoRect.Width, logoRect.Height); } logo.Alignment = iTextSharp.text.Image.ALIGN_LEFT; logo.SetAbsolutePosition(logoRect.Left, logoArea[2] + (logoRect.Height - logo.ScaledHeight) / 2); // left: logoArea[3] - logo.ScaledWidth + (logoRect.Width - logo.ScaledWidth) / 2 overContent.AddImage(logo); } } The problem with this is that the background colour of the field is set to white and the image then doesn't appear.. i remove the SetFieldProperty and RegenerateField commands and the image replacement works fine.. is there a way to set a stacking order on layers?

• sorting a gridview alphabetically when columns are codes

  - by nat

  hi there i have a gridview populated by a Web Service search function. some of the columns in the grid are templatefields, because the values coming back from the search (in a datatable) are ids - i then use these ids to lookup the values when the rowdatabound event is triggered and populate a label or some such. this means that my sorting function for these id/lookup columns sorts by the ids rather than the textual value that i have looked up and actually populated the grid with (although i do put the ids in the grids datakeys). what i want to do is top be able to sort by the looked up textual value rather than the codes for these particular columns. what i was going to do to get around this was to when the datatable comes back from the search, adding more columns the textual values and doing all the looking up then, thus being able to sort directly from the manually added columns. is there another way to do this? as that approach seems like a bit of a bodge. although i guess it does remove having to do the looking up in the rowdatabound event.... my sorting function works by sticking the datatable in the session and on each bind grabbing the sort column and binding the gridview to a DataView with the sort attribute set to the column - and the direction. thanks nat

• Querying a 3rd party website's database from my website

  - by Mong134

  The Goal: To retrieve information from a 3rd party database based off of a user's query on my ASP.NET website The Details: I need to be able to search 3rd-party websites for information relating to pharmaceutical drugs. Basically, here's what I've been tasked with: a user starts entering the name of a drug they're using in their experiments, and while they're typing a 3rd party website (e.g., here or here) is queried and suggestions are made based based off of what they've typed. Once they've made a selection, certain properties (molecular weight, chemical structure, etc) are retrieved from the 3rd party database and stored in our database. PharmaGKB.org's search bar is pretty much what I need to implement, but I need to access a 3rd party db. The site that I'm working on is ASP.NET/C#. The Problem: I don't really know where to start with this. There's a downloadable Perl example at the bottom of the page here, but it didn't really help me all that much. I'm at a loss as to how to implement this, or even find information about how to do it. The AJAX toolkit was suggested, but I'm not sure if that will solve the issue. JavaScript is also being considered, but again, I'm not sure if that will be sufficient, either. Perl Example Connection As a mentioned, here is a snippet from the Perl example given on the Pharmgkb.org site: my $call = SOAP::Lite -> readable (1) -> uri('SearchService') -> proxy('http://www.pharmgkb.org/services/SearchService') -> search ($ARGV[0]); However, I'm not sure how to implement this is C#/ASP.NET/JavaScript. There's a question on Stack Overflow about embedding Perl in C#, but it require a C wrapper as well, and I don't think that three languages is necessary or wise to solve this issue.

• Cloning input type file and set the value

  - by jribeiro

  I know that it isn't possible to set the value of an input type="file" for security reasons... My problem is: I needed to style an input type="file" so what I did was have a button and hide the file input. like: <a href="#" onclick="$('input[name=&quot;photo1&quot;]').click(); return false;" id="photo1-link"></a> <input type="file" name="photo1" class="fileInput jqtranformdone validate[required]" id="photo1" /> These works great in all browsers except IE which gives me an access denied error on submitting through ajax. I'm using the ajaxSubmit jquery plugin (malsup.com/jquery/form/) So after reading for a while I tried to do: var photo1Val = $('#photo1').val(); var clone1 = $('#photo1').clone().val(photo1Val); $('#photo1').remove(); clone1.appendTo('form'); console.log(photo1Val) //prints the right value C:/fakepath/blablabla.jpg $('form').ajaxSubmit(options); The problem is that after this the value of $('#photo1') is empty... Any ideas how to work around this? Thanks

I'm looking for an Opensource solution that I can customize to my need. The Scenario: A buyer reserves a lot, A form appears gathers his details after that he/she pays for the reservation. FrontEnd: I need a form builder extension in Joomla that I could build custom form in gathering information (name, email, contact info, address...) from the buyer or the person who is reserving it. After I gather the info I need another extension that will handle the payment for reserving it. This is kinda shopping cart type approach, you see a product and the buy it. But would just need extra details. Backend: I can see all the details of the buyer from their name to the time they paid for a reservation. Thanks! P.S. I'm open to all Ideas. I'm not sure of this approach. Please let me know If you have some good Ideas or example.

• Codeigniter: Library function--I'm stuck

  - by Kevin Brown

  I have a library function that sets up my forms, and submits data. They're long, and they work, so I'll spare you reading my code. :) I simply need a way for my functions to determine how to handle the data. Until now, the function did one thing: Submit a report for the current user. NOW, the client has requested that an administrator also be able to complete a form--this means that the form would be filled out, and it would CREATE a user at the same time, whereas the current function EDITS and is accessed by an EXISTING user. Do I need a separate function to do essentially the same thing? How do I make one function perform two tasks? One to update a user, and if there is no user, create one. Current controller: function survey() { $id = $this->session->userdata('id'); $data['member'] = $this->home_model->getUser($id); //Convert the db Object to a row array $data['manager'] = $data['member']->row(); $manager_id = $data['manager']->manager_id; $data['manager'] = $this->home_model->getUser($manager_id); $data['manager'] = $data['manager']->row(); $data['header'] = "Home"; $this->survey_form_processing->survey_form($this->_container,$data, $method); } Current Library: function survey_form($container) { //Lots of validation stuff $this->CI->validation->set_rules($rules); if ( $this->CI->validation->run() === FALSE ) { // Output any errors $this->CI->validation->output_errors(); } else { // Submit form $this->_submit(); } $this->CI->load->view($container,$data); The submit function is huge too. Basically says, "Update table with data where user_id=current user" I hope this wasn't too confusing. I'll create two functions if need be, but I'd like to keep redundancy down! }
