  • Sort ranges in an array in google apps script

    - by user1637113
    I have a timesheet spreadsheet for our company and I need to sort the employees by each timesheet block (15 rows by 20 columns). I have the following code which I had help with, but the array quits sorting once it comes to a block without an employee name (I would like these to be shuffled to the bottom). Another complication I am having is there are numerous formulas in these cells and when I run it as is, it removes them. I would like to keep these intact if at all possible. Here's the code: function sortSections() { var activeSheet = SpreadsheetApp.getActiveSheet(); //SETTINGS var sheetName = activeSheet.getSheetName(); //name of sheet to be sorted var headerRows = 53; //number of header rows var pageHeaderRows = 5; //page totals to top of next emp section var sortColumn = 11; //index of column to be sorted by; 1 = column A var pageSize = 65; var sectionSize = 15; //number of rows in each section var col = sortColumn-1; var sheet = SpreadsheetApp.getActive().getSheetByName(sheetName); var data = sheet.getRange(headerRows+1, 1, sheet.getMaxRows()-headerRows, sheet.getLastColumn()).getValues(); var data3d = []; var dataLength = data.length/sectionSize; for (var i = 0; i < dataLength; i++) { data3d[i] = data.splice(0, sectionSize); } data3d.sort(function(a,b){return(((a[0][col]<b[0][col])&&a[0][col])?-1:((a[0][col]>b[0][col])?1:0))}); var sortedData = []; for (var k in data3d) { for (var l in data3d[k]) { sortedData.push(data3d[k][l]); } } sheet.getRange(headerRows+1, 1, sortedData.length, sortedData[0].length).setValues(sortedData);

  • I need to sort the facets that come back from SOLR by relevancy

    - by Pinguthepenguin
    I have within my SOLR index song objects which belong to a higher level album object. An example is shown below: <song> <album title>Blood Sugar Sex Magic</album title> <song title>Under the Bridge</song title> <description>A sad song about junkies</description> </song> What I can do at the moment is create a facet on the album title so that a search on songs will also show me what albums contain hits for that keyword. The default behaviour for SOLR is that the facets are shown in the order of most hits to least. However what I want to achieve is the facet list to be sorted according to the relevancy of the top hit for that album. For example a search on the word "sad" may show a facet with one hit for "Blood Sugar Sex Magic" and there may also be an album called "Sad Clown songs" where there are 10 hits. "Sad clown songs" will show as the first facet even though it may be that "Under the bridge" comes up as the most relevant song. My question is how can I get all the facets back but then have them ordered by the relevancy of the songs within them? If I would need to change or extend some underlying SOLR code what would that be? Thanks in advance.

  • Error in bisection method code in Matlab

    - by Amanda Collins
    I need to write a proper implementation of the bisection method, which means I must address all possible user input errors. Here is my code: function [x_sol, f_at_x_sol, N_iterations] = bisection(f, xn, xp, eps_f, eps_x) % solving f(x)=0 with bisection method % f is the function handle to the desired function, % xn and xp are borders of search, % f(xn)<0 and f(xp)>0 required, % eps_f defines how close f(x) should be to zero, % eps_x defines uncertainty of solution x if(f(xp) < 0) error('xp must be positive') end; if(f(xn)>0) error('xn must be negative') end; if (xn >= xp) error ('xn must be less than xp') end; xg=(xp+xn)/2; %initial guess fg=f(xg); % initial function evaluation N_iterations=1; while ( (abs(fg) > eps_f) & (abs(xg-xp) > eps_x) ) if (fg>0) xp=xg; else xn=xg; end xg=(xp+xn)/2; %update guess fg=f(xg); %update function evaluation N_iterations=N_iterations+1; end x_sol=xg; %solution is ready f_at_x_sol=fg; if (f_at_x_sol > eps_f) error('No convergence') end and here is the error message I receive when I try to test this in Matlab: >> bisection(x.^2, 2, -1, 1e-8, 1e-10) Attempted to access f(-1); index must be a positive integer or logical. Error in bisection (line 9) if(f(xp)<0) I was attempting to see if my error codes worked, but it doesn't look like they do. I get the same error when I try to test it on a function that should work.

  • How to access the element of a list/vector that passed by reference in C++

    - by bsoundra
    Hi all, The problem is passing lists/vectors by reference int main(){ list<int> arr; //Adding few ints here to arr func1(&arr); return 0; } void func1(list<int> * arr){ // How Can I print the values here ? //I tried all the below , but it is erroring out. cout<<arr[0]; // error cout<<*arr[0];// error cout<<(*arr)[0];//error //How do I modify the value at the index 0 ? func2(arr);// Since it is already a pointer, I am passing just the address } void func2(list<int> *arr){ //How do I print and modify the values here ? I believe it should be the same as above but // just in case. } Is the vectors any different from the lists ? Thanks in advance. Any links where these things are explained elaborately will be of great help. Thanks again.

  • Stopping a MATLAB GUI callback

    - by leonhart88
    Dear All, I have a START and STOP button. When I hit START, i run a bunch of code in my callback. It's basically a sequential "script" that opens valves, dispenses water and then closes the valves...there is no while() loop and it doesn't repeat. I want to be able to stop this process at any time using the STOP button. Most of the related answers I've seen are in the cases where a while() loop is used. Some people have also suggested to periodically check if the STOP button was pressed (using a variable or handle variable). Since I do not have a while loop, I can't solve it that way. Also, I'd like to be able to exit immediately, without having to periodically check (because checking multiple times in my code would be ugly and confusing). Is there a way to terminate the callback which was interrupted by the STOP button? If not, is it possible to have the START button run a .m file and then have the STOP button terminate that .m file? The worst case scenario would be to check a variable periodically. UPDATE: Well, looks like the worst case scenario is what is suggested by MATLAB... http://www.mathworks.com/support/solutions/en/data/1-33IK85/index.html?product=ML&solution=1-33IK85 Thanks.

  • integrating jquery with AJAX using MVC for ddl/html.dropdownlist

    - by needhelp
    the situation: a user on the page in question selects a category from a dropdown which then dynamically populates all the users of that category in a second dropdown beside it. all the data is being retrieved using LinqtoSQL and i was wondering if this can be done a) using html.dropdownlist in a strongly typed view? b) using jquery to trigger the ajax request on selected index change instead of a 'populate' button trigger? sorry i dont have code as what i was trying really wasnt working at all. I am having trouble with how to do it conceptually and programatically! will appreciate any links to examples etc greatly! thanks in advance! EDIT: this is kind of what i was trying to achieve.. first the ViewPage: <script type="text/javascript"> $(document).ready function TypeSearch() { $.getJSON("/Home/Type", null, function(data) { //dont know what to do here }); } </script> <p> <label for="userType">userType:</label> <%= Html.DropDownList("userType") %> <%= Html.ValidationMessage("userType", "*") %> <input type="submit" runat="server" onclick="TypeSearch()" /> <label for="accountNumber">accountNumber:</label> <%= Html.DropDownList("accountNumber") %> <%= Html.ValidationMessage("accountNumber", "*") %> </p> Then home controller action: public ActionResult Type() { string accountType = dropdownvalue; List<Account> accounts = userRep.GetAccountsByType(accountType).ToList(); return Json(accounts); }

  • Struts2 jQuery Plugin Autocompleter renders HTML with style attributes <== changing this?

    - by Tim
    I'm using the Struts2 jQuery plugin 2.1 and render an autocompleter in my JSP. Here's the code: <s:form id="search-form" action="search" theme="simple"> <s:url id="remoteurl" action="jsonlanguages"/> <div> <sj:autocompleter cssClass="bgstandardelement empty" id="languages" name="echo" href="%{remoteurl}" delay="50" value="Search..." /> <input type="submit" id="search-button" value="GO" /> </div> </s:form> No matter what theme I set the autocompleter-form to, the HTML rendered for the list I output is always an unordered list with a style element that I cannot override. It has the following stype-attribute: style='z-index: 1; top: 242px; left: 926px; display: none; width: 256px'; As I want another outfit for my list, this doesn't work. Putting in the following attribute has no effect: cssStyle="width:115px!important;" What can I do?

  • crash when using stl vector at instead of operator[]

    - by Jamie Cook
    I have a method as follows (from a class than implements TBB task interface - not currently multithreading though) My problem is that two ways of accessing a vector are causing quite different behaviour - one works and the other causes the entire program to bomb out quite spectacularly (this is a plugin and normally a crash will be caught by the host - but this one takes out the host program as well! As I said quite spectacular) void PtBranchAndBoundIterationOriginRunner::runOrigin(int origin, int time) const // NOTE: const method { BOOST_FOREACH(int accessMode, m_props->GetAccessModes()) { // get a const reference to appropriate vector from member variable // map<int, vector<double>> m_rowTotalsByAccessMode; const vector<double>& rowTotalsForAccessMode = m_rowTotalsByAccessMode.find(accessMode)->second; if (origin != 129) continue; // Additional debug constrain: I know that the vector only has one non-zero element at index 129 m_job->Write("size: " + ToString(rowTotalsForAccessMode.size())); try { // check for early return... i.e. nothing to do for this origin if (!rowTotalsForAccessMode[origin]) continue; // <- this works if (!rowTotalsForAccessMode.at(origin)) continue; // <- this crashes } catch (...) { m_job->Write("Caught an exception"); // but its not an exception } // do some other stuff } } I hate not putting in well defined questions but at the moment my best phrasing is : "WTF?" I'm compiling this with Intel C++ 11.0.074 [IA-32] using Microsoft (R) Visual Studio Version 9.0.21022.8 and my implementation of vector has const_reference operator[](size_type _Pos) const { // subscript nonmutable sequence #if _HAS_ITERATOR_DEBUGGING if (size() <= _Pos) { _DEBUG_ERROR("vector subscript out of range"); _SCL_SECURE_OUT_OF_RANGE; } #endif /* _HAS_ITERATOR_DEBUGGING */ _SCL_SECURE_VALIDATE_RANGE(_Pos < size()); return (*(_Myfirst + _Pos)); } (Iterator debugging is off - I'm pretty sure) and const_reference at(size_type _Pos) const { // subscript nonmutable sequence with checking if (size() <= _Pos) _Xran(); return (*(begin() + _Pos)); } So the only difference I can see is that at calls begin instead of simply using _Myfirst - but how could that possibly be causing such a huge difference in behaviour?

  • C# why unit test has this strange behaviour?

    - by 5YrsLaterDBA
    I have a class to encrypt the connectionString. public class SKM { private string connStrName = "AndeDBEntities"; internal void encryptConnStr() { if(isConnStrEncrypted()) return; ... } private bool isConnStrEncrypted() { bool status = false; // Open app.config of executable. System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); // Get the connection string from the app.config file. string connStr = config.ConnectionStrings.ConnectionStrings[connStrName].ConnectionString; status = !(connStr.Contains("provider")); Log.logItem(LogType.DebugDevelopment, "isConnStrEncrypted", "SKM::isConnStrEncrypted()", "isConnStrEncrypted=" + status); return status; } } Above code works fine in my application. But not in my unit test project. In my unit test project, I test the encryptConnStr() method. it will call isConnStrEncrypted() method. Then exception (null pointer) will be thrown at this line: string connStr = config.ConnectionStrings.ConnectionStrings[connStrName].ConnectionString; I have to use index like this to pass the unit test: string connStr = config.ConnectionStrings.ConnectionStrings[0].ConnectionString; I remember it worked several days ago at the time I added above unit test. But now it give me an error. The unit test is not integrated with our daily auto build yet. We only have ONE connectionStr. It works with product but not in unit test. Don't know why. Anybody can explain to me?

  • Concept: Information Into Memory Location.

    - by Richeve S. Bebedor
    I am having troubles conceptualizing an algorithm to be used to transform any information or data into a specific appropriate and reasonable memory location in any data structure that I will be devising. To give you an idea, I have a JPanel object instance and I created another Container type object instance of any subtype (note this is in Java because I love this language), then I collected those instances into a data structure not specifically just for those instances but also applicable to any type of object. Now my procedure for fetching those data again is to extract the object specific features similar in category to all object in that data structure and transform it into a integer data memory location (specifically as much as possible) or any type of data that will pertain to this transformation. And I can already access that memory location without further sorting or applications of O(n) time complex algorithms (which I think preferable but I wanted to do my own way XD). The data structure is of any type either binary tree, linked list, arrays or sets (and the like XD). What is important is I don't need to have successive comparing and analysis of data just to locate information in big structures. To give you a technical idea, I have to an array DS that contains JLabel object instance with a specific name "HelloWorld". But array DS contains other types of object (in multitude). Now this JLabel object has a location in the array at index [124324] (which is if you do any type of searching algorithm just to arrive at that location is conceivably slow because added to it the data structure used was an array *note please disregard the efficiency of the data structure to be used I just want to explain to you my concept XD). Now I want to equate "HelloWorld" to 124324 by using a conceptually made function applicable to all data types. So that I can do a direct search by doing this DS[extractLocation("HelloWorld")] just to get that JLabel instance. I know this may sound crazy but I want to test my concept of non-sorting feature extracting search algorithm for any data structure wherein my main problem is how to transform information to be stored into memory location of where it was stored.

  • JQuery-AJAX: No further request after timeout and delay in form post

    - by Nogga
    I got a form containing multiple checkboxes. This form shall be sent to the server to receive appropriate results from a server side script. This is already working. What I would achieve now: 1) Implementing a timeout: This is already working, but as soon as a timeout occurs, a new request is not working anymore. 2) Implementing a delay in requesting results: A delay shall be implemented so that not every checkbox is resulting in a POST request. This is what I have right now: function update_listing() { // remove postings from table $('.tbl tbody').children('tr').remove(); // get the results through AJAX var request = $.ajax({ type: "POST", url: "http://localhost/hr/index.php/listing/ajax_csv", data: $("#listing_form").serialize(), timeout: 5000, success: function(data) { $(".tbl tbody").append(data); }, error: function(objAJAXRequest, strError) { $(".tbl tbody").append("<tr><td>failed " + strError + "</td></tr>"); } }); return true; } Results are for now passed as HTML table rows - I will transform them to CSV/JSON in the next step. Thanks so much for your advice.

  • CSS Sprite for images which have vertical as well as horizontal repeats

    - by Rachel
    I have four images, one of which has background repeat property in horizontal direction and three of which have background repeat in vertical direction. I have different CSS classes which currently uses this images as under: .sb_header_dropdown { background: url(images/shopping_dropdown_bg.gif) repeat-y top left; padding: 8px 3px 8px 15px; } .shopping_basket_dropdown .sb_body { background: url(images/shopping_dropdown_body_bg.png) repeat-y top left; margin: 0; padding: 5px 9px 5px 8px; position: relative; z-index: 99999; } .checkout_cart .co_header_left { background: url(images/bg.gif) repeat-x 0 -150px; overflow: hidden; padding-left: 3px; } .sb_dropdown_footer { background: url(images/shopping_dropdown_footer_bg.png) repeat-y top left; clear: both; height: 7px; font-size: 0; } So here am making 4 HTTP Request and I want to implement CSS Sprite for all 4 images such that I can reduce the number of HTTP Request from 4 to 1, also thing to keep in mind is that here we have background repeat for all 4 images, either on x-direction or on y-direction and so how should sprite be created and how it can be used in the CSS to reduce the number of HTTP request. I hope this question is clear.

  • where to store temporary data in MVC 2.0 project

    - by StuffHappens
    Hello! I'm starting to learn MVC 2.0 and I'm trying to create a site with a quiz: user is asked a question and given several options of answer. If he chooses the right answer he gets some points, if he doesn't, he looses them. I tried to do this the following way public class HomeController : Controller { private ITaskGenerator taskGenerator = new TaskGenerator(); private string correctAnswer; public ActionResult Index() { var task = taskGenerator .GenerateTask(); ViewData["Task"] = task.Task; ViewData["Options"] = task.Options; correctAnswer= task.CorrectAnswer; return View(); } public ActionResult Answer(string id) { if (id == correctAnswer) return View("Correct") return View("Incorrect"); } } But I have a problem: when user answers the cotroller class is recreated and I loose correct answer. So what is the best place to store correct answer? Should I create a static class for this purpose? Thanks for your help!

  • JQueryMobile 1.1.1 List items not anchoring to the left

However, when I use the code below the button element of the list isn't anchored to the left of the list item and instead appears centered...Can anyone help me? It's driving me crazy!

  • Iterate Through JSON Data for Specific Element - Similar to XPath

    - by Highroller
    I am working on an embedded system and my theory of the overall process follows this methodology: 1. Send a command to the back end asking for account information in JSON format. 2. The back end writes a JSON file with all accounts and associated information (there could be 0 to 16 accounts). 3. Here's where I get stuck - use JavaScript (we are using the JQuery library) to iterate through the returned information for a specific element (similar to XPath) and build an array based on the number of elements found to populate a drop-down box to select the account you want to view and then do stuff with the account info. So my code looks like this: loadAccounts = function() { $.getJSON('/info?q=voip.accounts[]', function(result) { var sipAcnts = $("#sipacnts"); $(sipAcnts).empty(); // empty the dropdown (if necessarry) // Get the 'label' element and stick it in an array // build the array and append it to the sipAcnts dropdown // use array index to ref the accounts info and do stuff with it } So what I need is the JSON version of XPath to build the array of voip.accounts.label. The first account info looks something like this: { "result_set": { "voip.accounts[0]": { "label": "Dispatch1", "enabled": true, "user": "1234", "name": "Jane Doe", "type": "sip", "sip": { "lots and lots of stuff": }, } } } Am I over complicating the issue? Any wisdom anyone could thrown down would be greatly appreciated.

  • IE7 & IE8 error executing function with ajax

    - by Yahreen
    I am loading an ajax page which executes an HTML5 video player script. The function for the Flash fallback is html5media(); : //Load 1st Case Study $("#splash").live('click', function (e) { $(this).fadeOut('slow', function () { $('#case-studies').load('case-study-1.html', function() { html5media(); //initiate Flash fallback }).fadeIn(); }); e.preventDefault(); }); This initial page load works fine in IE7 & IE8. The problem is once this page is loaded, there are links to 4 more videos which are loaded in again using ajax. I use this function: //Switcher function csClients(url, client) { $("#case-studies").fadeOut('slow', function() { $('#case-studies').load(url, function () { html5media(); //initiate Flash fallback }).fadeIn(); }); } //Page Loader $("#cs-client-list li.client1 a").live('click', function(e) { csClients('case-study-1.html', 'client1'); e.preventDefault(); }); Originally I was using return false; but none of the sub-page Flash videos would load in IE7. When I switched to preventDefault, the videos loaded in IE7 but still not in IE8. I also get a weird error in both IE7 & IE8 with no helpful feedback: Error on Page: Unspecified error. / (Line 49) Code: 0 (Char 5) URI: http://www.mysite.com This is line 49 in my index page: <section id="case-studies" class="main-section"> I have a feeling it has to do with calling html5media(); too many times?

Next let's assume that after a while I would like to purge old messages because they aren't useful anymore and I want to save memory. Let's say at time x messages[1-3] became stale. I assume that it would be most efficient to just do the deletion once every x seconds. Next my datastructure should contain: 4. "my" 5. "car" My solution? I was thinking of using a concurrentskiplistset or concurrentskiplist map. Also I was thinking of deleting the old messages from inside a newSingleThreadScheduledExecutor. I would like to know how you would implement(efficiently/thread-safe) this or maybe use a library?

  • Why my http POST request doesn't go well?

    - by 0x90
    I am trying to make this POST request in ruby. but get back #<Net::HTTPUnsupportedMediaType:0x007f94d396bb98> what I tried is: require 'rubygems' require 'net/http' require 'uri' require 'json' auto_index_nodes =URI('http://localhost:7474/db/data/index/node/') request_nodes = Net::HTTP::Post.new(auto_index_nodes.request_uri) http = Net::HTTP.new(auto_index_nodes.host, auto_index_nodes.port) request_nodes.add_field("Accept", "application/json") request_nodes.set_form_data({"name"=>"node_auto_index", "config" => { "type" => "fulltext", "provider" =>"lucene"} , "Content-Type" => "application/json" }) response = http.request(request_nodes) Tried to write this part: "config" => { "type" => "fulltext", provider" =>"lucene"} , "Content-Type" => "application/json" } like that: "config" => '{ "type" => "fulltext",\ "provider" =>"lucene"},\ "Content-Type" => "application/json"\ }' this try didn't help either: request_nodes.set_form_data({"name"=>"node_auto_index", "config" => '{ \ "type" : "fulltext",\ "provider" : "lucene"}' , "Content-Type" => "application/json" })

  • How to identify multiple identical pairs in two vectors

    - by Sacha Epskamp
    In my graph-package (as in graph theory, nodes connected by edges) I have a vector indicating for each edge the node of origin from, a vector indicating for each edge the node of destination to and a vector indicating the curve of each edge curve. By default I want edges to have a curve of 0 if there is only one edge between two nodes and curve of 0.2 if there are two edges between two nodes. The code that I use now is a for-loop, and it is kinda slow: curve <- rep(0,5) from<-c(1,2,3,3,2) to<-c(2,3,4,2,1) for (i in 1:length(from)) { if (any(from==to[i] & to==from[i])) { curve[i]=0.2 } } So basically I look for each edge (one index in from and one in to) if there is any other pair in from and to that use the same nodes (numbers). What I am looking for are two things: A way to identify if there is any pair of nodes that have two edges between them (so I can omit the loop if not) A way to speed up this loop # EDIT: To make this abit clearer, another example: from <- c(4L, 6L, 7L, 8L, 1L, 9L, 5L, 1L, 2L, 1L, 10L, 2L, 6L, 7L, 10L, 4L, 9L) to <- c(1L, 1L, 1L, 2L, 3L, 3L, 4L, 5L, 6L, 7L, 7L, 8L, 8L, 8L, 8L, 10L, 10L) cbind(from,to) from to [1,] 4 1 [2,] 6 1 [3,] 7 1 [4,] 8 2 [5,] 1 3 [6,] 9 3 [7,] 5 4 [8,] 1 5 [9,] 2 6 [10,] 1 7 [11,] 10 7 [12,] 2 8 [13,] 6 8 [14,] 7 8 [15,] 10 8 [16,] 4 10 [17,] 9 10 In these two vectors, pair 3 is identical to pair 10 (both 1 and 7 in different orders) and pairs 4 and 12 are identical (both 2 and 8). So I would want curve to become: [1,] 0.0 [2,] 0.0 [3,] 0.2 [4,] 0.2 [5,] 0.0 [6,] 0.0 [7,] 0.0 [8,] 0.0 [9,] 0.0 [10,] 0.2 [11,] 0.0 [12,] 0.2 [13,] 0.0 [14,] 0.0 [15,] 0.0 [16,] 0.0 [17,] 0.0 (as I vector, I transposed twice to get row numbers).

  • Does anybody have any tips for managing polymorphic nested resources in Rails 3?

    - by Ryan
    in config/routes.rb: resources posts do resources comments end resources pictures do resources comments end I would like to allow for more things to be commented on as well. I'm currently using mongoid (mongomapper isn't as compatible with rails3 yet as I would like), and comments are an embedded resource (mongoid can't yet handle polymorphic relational resources), which means that I do need the parent resource in order to find the comment. Are there any elegant ways to handle some of the following problems: in my controller, I need to find the parent before finding the comment. if params[:post_id] parent = Post.find(params[:post_id] else if params[:picture_id] parent = Picture.find(params[:picture_id] end which is going to get messy if I start adding more things to be commentable also url_for([comment.parent,comment]) doesn't work, so I'm going to have to define something in my Comment model, but I think I'm also going to need to define an index route in the Comment model as well as potentially an edit and new route definition. There might be more issues that I have to deal with as I get further. I can't imagine I'm the first person to try and solve this problem, are there any solutions out there to make this more manageable?
