  • CI+JQuery+Ajax problem

    - by Sadat
    Calling the ajax called URL works well without ajax eg. http://localhost/ci/controller/method/param_value. But using ajax it doesnt work. Following are the code segment, i have just started with JQuery+Ajax with CI. Here is my controller: <?php class BaseController extends Controller{ public function BaseController(){ parent::Controller(); $this->load->helper('url'); } function index(){ $this->load->view('header'); $this->load->view('body'); $this->load->view('footer'); } function ajaxTest($testData=""){ $this->load->view('ajaxtest',array('test_data'=>$testData)); } } ? Here is View <?php echo $test_data; ? Ajax Call Function function testAjaxCall(){ $.get( base_url+'basecontroller/ajaxtest/test-value', function(responseData) { $("#test-div").html(responseData); } ); } Ajax Calling Page(button) <div id="test-div"></div><input type="button" onclick="testAjaxCall()" name="ajax-test" value="Test Ajax" /> JS base_url declaration <script type="text/javascript" src="<?php echo base_url();?>js/jquery.js"></script> <script type="text/javascript" src="<?php echo base_url();?>js/application-ajax-call.js"></script> <script type="text/javascript"> /* to make ajax call easy */ base_url = '<?php echo base_url();?>'; </script>

  • How to retrieve value from ViewData when the object is not a string?

    - by Richard77
    Hello, Here's the functionality I'd like to exploit: I've a class myClass and would like to iterate over a collection that contains all the properties of that class. I'd like to send the index of that collection along with the other data so that I can control the each sequence of the iteration. Here's simplified versions of a Action method and View (I'll use the same action-view for that functionality). 1) Action public ActionResult CreateHierarchy(int? index) { if(index < PropertiesOfMyClass.Lenght) { //Other code omitted ViewData["index"] = ((index == null) ? 1 : index++); Return View(); } } 2)View <% Using(Html.BeginForm()){%> //Other Code omitted <% = Html.Hidden("Index", ViewData["index"])%> <input type = "submit" value = "Do someting"/> <%}%> I've also placed this at the bottom of the page so that I can check the value of the index, <% = ViewData["index"]%> Unfortunately, its not working. I'm getting only the number 1. I'm missing something? such as a cast for the Viewdata? Should I write something like this: <% = Html.Hidden("index", (int)ViewData["index"])%> It's not working either Thanks for helping

  • Jquery Ui DatePicker, attaches to textbox but only works once, then all click events are disabled.

Any ideas?

  • Time complexity with bit cost

    - by Keyser
    I think I might have completely misunderstood bit cost analysis. I'm trying to wrap my head around the concept of studying an algorithm's time complexity with respect to bit cost (instead of unit cost) and it seems to be impossible to find anything on the subject. Is this considered to be so trivial that no one ever needs to have it explained to them? Well I do. (Also, there doesn't even seem to be anything on wikipedia which is very unusual). Here's what I have so far: The bit cost of multiplication and division of two numbers with n bits is O(n^2) (in general?) So, for example: int number = 2; for(int i = 0; i < n; i++ ){ number = i*i; } has a time complexity with respect to bit cost of O(n^3), because it does n multiplications (right?) But in a regular scenario we want the time complexity with respect to the input. So, how does that scenario work? The number of bits in i could be considered a constant. Which would make the time complexity the same as with unit cost except with a bigger constant (and both would be linear). Also, I'm guessing addition and subtraction can be done in constant time, O(1). Couldn't find any info on it but it seems reasonable since it's one assembler operation.

  • Which language should I pick up: VB.Net or C#

    - by magius
    I'm looking to pick up either C# or VB.Net. I'd done a fair bit of VB6 programming in the past. I'm looking at getting the book, Visual Basic .NET or C#, Which to Choose? but I'm hoping that someone has read it, or used both languages and can offer advice. Should I just RTFB? Edit: Anders Sandvig raised a valid question. I'm intending to develop ActiveX applications that will be served through IE. Edit: Given that the functionality is pretty close and my favored approach to learning is to "just build it" and solve problems by looking it up on the internet, I've decided that the choice of language will be based on how easy it is to learn it. I looked around and found sites like C# Corner that supports my approach. Personal note: I wish I could also select Seb Nilsson's response as an accepted answer as well. Thanks guys for your input! Alright, then! I admit, theoretically, this topic is subjective; but a quick tally of answers seems to skew votes heavily in C#'s favor. Anyway, I'm really after experiences like what Keith's alluding to. I'm hoping he'll return to this topic and drop us a few more gems.

  • jquery form wizard validation

    - by SoulieBaby
    Hi all, I'm trying to implement a validation script (bassistance) with a jquery form wizard (http://www.jankoatwarpspeed.com/post/2009/09/28/webform-wizard-jquery.aspx) but I'm having some problems. On the page for the jquery wizard, a guy named "Tommy" came up with a piece of code to implement bassistance with the code. But for some reason I can't get it to work. It comes up saying if the field needs to be filled in etc and the next button doesn't work - which is fine, BUT, if I fill in all the fields, the next button still doesn't work.. function createNextButton(i) { var stepName = "step" + i; $("#" + stepName + "commands").append("<a href='#' id='" + stepName + "Next' class='next'>Next ></a>"); /* VALIDATION */ if (options.validationEnabled) { var stepIsValid = true; $("#" + stepName + " :input").each(function(index) { stepIsValid = !element.validate().element($(this)) && stepIsValid; }); if (!stepIsValid) { return false; } } /* END VALIDATION */ $("#" + stepName + "Next").bind("click", function(e) { $("#" + stepName).hide(); $("#step" + (i + 1)).show(); if (i + 2 == count) $(submmitButtonName).show(); selectStep(i + 1); }); } Could someone help me figure this one out? :)

  • problem with RenderOuterTable property for .net 4.0 controls

    - by Mario
    According to the new 4.0 framework overview, one should be able to add the attrib RenderOuterTable="false" to a control that supports the attribute and see css friendly code be spit out - in other words no html tables. To test this, I threw a login control into a basic fresh webpage with the following code: <asp:Login ID="Login1" runat="server" RenderOuterTable="false"></asp:Login> The result? Crappy html table output, which supposedly doesn't happen with this attrib set to false. Here is the output: &lt;table cellpadding=&quot;0&quot;&gt; <tr> <td align="center" colspan="2">Log In</td> </tr><tr> <td align="right"><label for="MainContent_Login1_UserName">User Name:</label></td><td><input name="ctl00$MainContent$Login1$UserName" type="text" id="MainContent_Login1_UserName" /><span id="MainContent_Login1_UserNameRequired" title="User Name is required." style="visibility:hidden;">*</span></td>... Hopefully you get the point. Anyone know how to stop these controls from outputting tables? This is super annoying.

  • What's the best way to read a UDT from a database with Java?

    - by Lukas Eder
    I thought I knew everything about UDTs and JDBC until someone on SO pointed out some details of the Javadoc of java.sql.SQLInput and java.sql.SQLData JavaDoc to me. The essence of that hint was (from SQLInput): An input stream that contains a stream of values representing an instance of an SQL structured type or an SQL distinct type. This interface, used only for custom mapping, is used by the driver behind the scenes, and a programmer never directly invokes SQLInput methods. This is quite the opposite of what I am used to do (which is also used and stable in productive systems, when used with the Oracle JDBC driver): Implement SQLData and provide this implementation in a custom mapping to ResultSet.getObject(int index, Map mapping) The JDBC driver will then call-back on my custom type using the SQLData.readSQL(SQLInput stream, String typeName) method. I implement this method and read each field from the SQLInput stream. In the end, getObject() will return a correctly initialised instance of my SQLData implementation holding all data from the UDT. To me, this seems like the perfect way to implement such a custom mapping. Good reasons for going this way: I can use the standard API, instead of using vendor-specific classes such as oracle.sql.STRUCT, etc. I can generate source code from my UDTs, with appropriate getters/setters and other properties My questions: What do you think about my approach, implementing SQLData? Is it viable, even if the Javadoc states otherwise? What other ways of reading UDT's in Java do you know of? E.g. what does Spring do? what does Hibernate do? What does JPA do? What do you do? Addendum: UDT support and integration with stored procedures is one of the major features of jOOQ. jOOQ aims at hiding the more complex "JDBC facts" from client code, without hiding the underlying database architecture. If you have similar questions like the above, jOOQ might provide an answer to you.

  • Efficient way of calculating average difference of array elements from array average value

    - by Saysmaster
    Is there a way to calculate the average distance of array elements from array average value, by only "visiting" each array element once? (I search for an algorithm) Example: Array : [ 1 , 5 , 4 , 9 , 6 ] Average : ( 1 + 5 + 4 + 9 + 6 ) / 5 = 5 Distance Array : [|1-5|, |5-5|, |4-5|, |9-5|, |6-5|] = [4 , 0 , 1 , 4 , 1 ] Average Distance : ( 4 + 0 + 1 + 4 + 1 ) / 5 = 2 The simple algorithm needs 2 passes. 1st pass) Reads and accumulates values, then divides the result by array length to calculate average value of array elements. 2nd pass) Reads values, accumulates each one's distance from the previously calculated average value, and then divides the result by array length to find the average distance of the elements from the average value of the array. The two passes are identical. It is the classic algorithm of calculating the average of a set of values. The first one takes as input the elements of the array, the second one the distances of each element from the array's average value. Calculating the average can be modified to not accumulate the values, but caclulating the average "on the fly" as we sequentialy read the elements from the array. The formula is: Compute Running Average of Array's elements ------------------------------------------- RA[i] = E[i] {for i == 1} RA[i] = RA[i-1] - RA[i-1]/i + A[i]/i { for i > 1 } Where A[x] is the array's element at position x, RA[x] is the average of the array's elements between position 1 and x (running average). My question is: Is there a similar algorithm, to calculate "on the fly" (as we read the array's elements), the average distance of the elements from the array's mean value? The problem is that, as we read the array's elements, the final average value of the array is not known. Only the running average is known. So calculating differences from the running average will not yield the correct result. I suppose, if such algorithm exists, it probably should have the "ability" to compensate, in a way, on each new element read for the error calculated as far.

  • MVC2 Client Validation isn't working when getting form from ajax call

    - by devlife
    I'm trying to use MVC2 client-side validation in a partial view that is rendered via $.get. However, the client validation isn't working. I'm not quite sure what the deal is. [Required(ErrorMessage = "Email is required")] public string Email { get; set; } <% using ( Ajax.BeginForm( new AjaxOptions { Confirm = "You sure?" } ) ) { %> <%: Html.TextBoxFor( m => m.Email, new { @class = "TextBox150" } )%> <%= Html.ValidationMessageFor( m => m.Email )%> <input type="submit" value="Add/Save" style="float: right;" /> <% } %> I'm not doing anything special to render the the partial view. Just putting the html into a div and showing it in a modal popup. On a side note, does anyone know if it's possible to submit the form with client validation without a submit button?

  • Interpolating environment variables into a string in Ruby using String#scan

    - by robc
    I'm trying to interpolate environment variables into a string in Ruby and not having much luck. One of my requirements is to do something (log an error, prompt for input, whatever) if a placeholder is found in the initial string that has no matching environment variable. It looks like the block form of String#scan is what I need. Below is an irb session of my failed attempt. irb(main):014:0> raw_string = "need to replace %%FOO%% and %%BAR%% in here" => "need to replace %%FOO%% and %%BAR%% in here" irb(main):015:0> cooked_string << raw_string => "need to replace %%FOO%% and %%BAR%% in here" irb(main):016:0> raw_string.scan(/%%(.*?)%%/) do |var| irb(main):017:1* cooked_string.sub!("%%#{var}%%", ENV[var]) irb(main):018:1> done irb(main):019:1> end TypeError: cannot convert Array into String from (irb):17:in `[]' from (irb):17 from (irb):16:in `scan' from (irb):16 from :0 If I use ENV["FOO"] to manually interpolate one of those, it works fine. I'm banging my head against the desk. What am I doing wrong? Ruby is 1.8.1 on RHEL or 1.8.7 on Cygwin.

  • Authenticating GTK app to run with root permissions

    - by Thomas Tempelmann
    I have a UI app (uses GTK) for Linux that requires to be run as root (it reads and writes /dev/disk*). Instead of requiring the user to open a root shell or use "sudo" manually every time when he launches my app, I wonder if the app can use some OS-provided API to ask the user to relaunch the app with root permissions. (Note: gtk app's can't use "setuid" mode, so that's not an option here.) The advantage here would be an easier workflow: The user could, from his default user account, double click my app from the desktop, and the app then would relaunch itself with root permission after been authenticated by the API/OS. I ask this because OS X offers exactly this: An app can ask the OS to launch an executable with root permissions - the OS (and not the app) then asks the user to input his credentials, verifies them and then launches the target as desired. I wonder if there's something similar for Linux (Ubuntu, e.g.) Update: The app is a remote operated disk repair tool for the unsavvy Linux user, and those Linux noobs won't have much understanding of using sudo or even changing their user's group memberships, especially if their disk just started acting up and they're freaking out. That's why I seek a solution that avoids technicalities like this.

  • Overriding equals method without breaking symmetry in a class that has a primary key

    - by Kosta
    Hi, the answer to this question is probably "not possible", but let me ask regardless :) Assuming we have a very simple JAVA class that has a primary key, for example: class Person { String ssid; String name; String address; ... } Now, I want to store people in a collection, meaning I will have to override the equals method. Not a completely trivial matter, but on a bare basis I will have something along the lines of: @Override public boolean equals (Object other) { if(other==this) return true; if(!other.getClass().equals(this.getClass()) return false; Person otherPerson = (Person)other; if(this.ssid.equals(otherPerson.getSsid()) return true; } Excuse any obvious blunders, just typing this out of my head. Now, let's say later on in the application I have a ssid I obtained through user input. If I want to compare my ssid to a Person, I would have to call something like: String mySsid = getFromSomewhere(); Person myPerson = getFromSomewhere(); if(myPerson.equals(new Person(mySsid)) doSomething(); This means I have to create a convenience constructor to create a Person based on ssid (if I don't already have one), and it's also quite verbose. It would be much nicer to simply call myPerson.equals(mySsid) but if I added a string comparison to my Person equals class, that would break the symmetry property, since the String hasn't got a clue on how to compare itself to a Person. So finally, the big question, is there any way to enable this sort of "shorthand" comparisons using the overriden equals method, and without breaking the symmetry rule? Thanks for any thoughts on this!

  • C# and SQL - sub select from a table parameter

    - by Dr.HappyPants
    Below is a code snippet for passing a table as a parameter to a query that can be used in Sql Server 2008. I'm confused though about the "SELECT id.custid FROM @custids id". Why does it use id.custid and @custids id...? private static void datatable_example() { string [] custids = {"ALFKI", "BONAP", "CACTU", "FRANK"}; DataTable custid_list = new DataTable(); custid_list.Columns.Add("custid", typeof(String)); foreach (string custid in custids) { DataRow dr = custid_list.NewRow(); dr["custid"] = custid; custid_list.Rows.Add(dr); } using(SqlConnection cn = setup_connection()) { using(SqlCommand cmd = cn.CreateCommand()) { cmd.CommandText = @"SELECT C.CustomerID, C.CompanyName FROM Northwind.dbo.Customers C WHERE C.CustomerID IN (SELECT id.custid FROM @custids id)"; cmd.CommandType = CommandType.Text; cmd.Parameters.Add("@custids", SqlDbType.Structured); cmd.Parameters["@custids"].Direction = ParameterDirection.Input; cmd.Parameters["@custids"].TypeName = "custid_list_tbltype"; cmd.Parameters["@custids"].Value = custid_list; using (SqlDataAdapter da = new SqlDataAdapter(cmd)) using (DataSet ds = new DataSet()) { da.Fill(ds); PrintDataSet(ds); } } }

  • ASP.NET MVC 2 strange behavior

    - by Voice
    Hi Recently I installed VS 2010 Release (migrated from RC) and my MVC application is not working anymore. More concrete: I have a wizard with several steps for new customer account creation (Jquery form wizard, but it doesn't really matter). Each step contains a typed partial View for each part of account: Company, Customer, Licence, etc. When I submit the form I see really strange thing in ModelState. There are duplicate keys for Company: with "Company" prefix and without it. Something like this: [6] "Company.Phone" string [12] "Phone" string My model state for all these keys is not valid because Company is actually null and validation fails. When it was RC there were no such keys with "Company" prefix. So these keys in ModelState with prefix "Company" appeared after I installed VS Release. Here is my code: Main View <div id="registerSteps"> <div id="firstStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.CustomerInfo) %></legend> <% Html.RenderPartial("CustomerInfo", ViewData["newCust"]); %> </fieldset> </div> <div id="secondStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.CompanyInfo) %></legend> <% Html.RenderPartial("CompanyInfo", ViewData["newComp"]); %> </fieldset> </div> <div id="thirdStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.LicenceInfo) %></legend> <% Html.RenderPartial("LicenceInfo", ViewData["newLic"]); %> </fieldset> </div> <div id="lastStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.PrivacyStatement) %></legend> <% Html.RenderPartial("PrivacyStatementInfo"); %> </fieldset> </div> <div id="registerNavigation"> <input class="navigation_button" value="Back" type="reset"/> <input class="navigation_button" value="Next" type="submit"/> </div> </div> Two partial views (to show that they are actually identical): Company: <div id="dCompanyInfo"> <div> <div> <%=Html.LocalizableLabelFor(company => company.Name, Register.CompanyName) %> </div> <div> <%=Html.TextBoxFor(company => company.Name) %> <%=Html.ValidationMessageFor(company => company.Name) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Phone, Register.Phone) %> </div> <div> <%=Html.TextBoxFor(company => company.Phone) %> <%=Html.ValidationMessageFor(company => company.Phone) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Fax, Register.Fax) %> </div> <div> <%=Html.TextBoxFor(company => company.Fax) %> <%=Html.ValidationMessageFor(company => company.Fax) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Size_ID, Register.CompanySize) %> </div> <div> <%=Html.ValueListDropDown(company => company.Size_ID, (CodeRoad.AQua.DomainModel.ValueList)ViewData["CompSize"], (string)ViewData["Culture"]) %> <%=Html.ValidationMessageFor(company => company.Size_ID) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Industry_ID, Register.Industry) %> </div> <div> <%=Html.ValueListDropDown(company => company.Industry_ID, (CodeRoad.AQua.DomainModel.ValueList)ViewData["Industry"], (string)ViewData["Culture"]) %> <%=Html.ValidationMessageFor(company => company.Industry_ID) %> </div> </div> </div> And for Customer <div id="dCustomerInfo"> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.Email, Register.Email) %> </div> <div> <%=Html.TextBoxFor(customer => customer.Email) %> <%=Html.ValidationMessageFor(customer => customer.Email) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.Male, Register.Gender) %> </div> <div> <%=Html.ListBoolEditor(customer => customer.Male, Register.Male, Register.Female, Register.GenderOptionLabel) %> <%=Html.ValidationMessageFor(customer => customer.Male) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.FirstName, Register.FirstName) %> </div> <div> <%=Html.TextBoxFor(customer => customer.FirstName) %> <%=Html.ValidationMessageFor(customer => customer.FirstName) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.LastName, Register.LastName) %> </div> <div> <%=Html.TextBoxFor(customer => customer.LastName) %> <%=Html.ValidationMessageFor(customer => customer.LastName) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.Role_ID, Register.Role) %> </div> <div> <%=Html.ValueListDropDown(customer => customer.Role_ID, (CodeRoad.AQua.DomainModel.ValueList)ViewData["OrgRole"], (string)ViewData["Culture"]) %> <%=Html.ValidationMessageFor(customer => customer.Role_ID) %> </div> </div> </div> There are some home made extension methods, but they worked pretty well in previous version (VS RC). Html which is generated is also ok, no "Company.Phone"-like stuff. So I wonder, where all these keys with "Company" came from and what can I do with that? I appreciate any solution.

  • Rot13 for numbers.

    - by dreeves
    EDIT: Now a Major Motion Blog Post at http://messymatters.com/sealedbids The idea of rot13 is to obscure text, for example to prevent spoilers. It's not meant to be cryptographically secure but to simply make sure that only people who are sure they want to read it will read it. I'd like to do something similar for numbers, for an application involving sealed bids. Roughly I want to send someone my number and trust them to pick their own number, uninfluenced by mine, but then they should be able to reveal mine (purely client-side) when they're ready. They should not require further input from me or any third party. (Added: Note the assumption that the recipient is being trusted not to cheat.) It's not as simple as rot13 because certain numbers, like 1 and 2, will recur often enough that you might remember that, say, 34.2 is really 1. Here's what I'm looking for specifically: A function seal() that maps a real number to a real number (or a string). It should not be deterministic -- seal(7) should not map to the same thing every time. But the corresponding function unseal() should be deterministic -- unseal(seal(x)) should equal x for all x. I don't want seal or unseal to call any webservices or even get the system time (because I don't want to assume synchronized clocks). (Added: It's fine to assume that all bids will be less than some maximum, known to everyone, say a million.) Sanity check: > seal(7) 482.2382 # some random-seeming number or string. > seal(7) 71.9217 # a completely different random-seeming number or string. > unseal(seal(7)) 7 # we always recover the original number by unsealing.

Why?

  • I can't get datepicker to work

    - by vikitor
    Hi, I need a field that displays the datepicker. I followed the example given by the JQuery UI documentation and haven't managed to get it to work. My html where I have my text field is: <div class="editor-field"> <input type = "text" name = "DatePublished" id = "Published" /> <%= Html.ValidationMessage("DatePublished" ,"*") %> </div> This HTML is in a partial view, lets call it pv.ascx, and it is called in the main page as a modal box: <div id = "ModalBox"> <% Html.RenderAction("pv", "Example"); %> </div> The thing is, that I try to call the datepicker creation anytime I enter the main page, and I do it in my javascript file app.js: $().ready(function() { var place = window.location.pathname; var placesplit = place.split("/"); //Depending on the location we are on, we execute different subroutines $('#Published').datepicker(); }); But nothing happens when I focus on the text field. What is wrong? Could it be that being called from a partial view it doesn't work? Thank you everyone, vikitor

  • Create image from scratch with JMagick

    I am using Java port of ImageMagick called JMagick .I need to be able to create a new image and write an arbitrary text chunk into it.The docs are very poor and what I managed to get so far is to write text into the image which comes from IO.Also , in all the examples I have found it seems like the very first operation ,before writing new image data , is always loading of an existing image into ImageInfo instance.How do I create an image from scratch with JMagick and then write a text into it? Here is what I do now : try { ImageInfo info = new ImageInfo(); info.setSize("512x512"); info.setUnits(ResolutionType.PixelsPerInchResolution); info.setColorspace(ColorspaceType.RGBColorspace); info.setBorderColor(PixelPacket.queryColorDatabase("red")); info.setDepth(8); BufferedImage img = new BufferedImage(512,512,BufferedImage.TYPE_4BYTE_ABGR); byte[] imageBytes = ((DataBufferByte) img.getData().getDataBuffer()).getData(); MagickImage mimage = new MagickImage(info,imageBytes); DrawInfo aInfo = new DrawInfo(info); aInfo.setFill(PixelPacket.queryColorDatabase("green")); aInfo.setUnderColor(PixelPacket.queryColorDatabase("yellow")); aInfo.setOpacity(0); aInfo.setPointsize(36); aInfo.setFont("Arial"); aInfo.setTextAntialias(true); aInfo.setText("JMagick Tutorial"); aInfo.setGeometry("+40+40"); mimage.annotateImage(aInfo); mimage.setFileName("text.jpg"); mimage.writeImage(info); } catch (MagickException ex) { Logger.getLogger(LWJGL_IDOMOO_SIMPLE_TEST.class.getName()).log(Level.SEVERE, null, ex); } It doesn't work , the JVM crashes with access violation as it probably expects for the input image from IO.

  • Why do my Sax Parser produce no results after using InputStream Read?

    - by Andy Barlow
    Hello, I have this piece of code which I'm hoping will be able to tell me how much data I have downloaded (and soon put it in a progress bar), and then parse the results through my Sax Parser. If I comment out basically everything above the //xr.parse(new InputSource(request.getInputStream())); line and swap the xr.parse's over, it works fine. But at the moment, my Sax parser tells me I have nothing. Is it something to do with is.read (buffer) section? Also, just as a note, request is a HttpURLConnection with various signatures. /*Input stream to read from our connection*/ InputStream is = request.getInputStream(); /*we make a 2 Kb buffer to accelerate the download, instead of reading the file a byte at once*/ byte [ ] buffer = new byte [ 2048 ] ; /*How many bytes do we have already downloaded*/ int totBytes,bytes,sumBytes = 0; totBytes = request.getContentLength () ; while ( true ) { /*How many bytes we got*/ bytes = is.read (buffer); /*If no more byte, we're done with the download*/ if ( bytes <= 0 ) break; sumBytes+= bytes; Log.v("XML", sumBytes + " of " + totBytes + " " + ( ( float ) sumBytes/ ( float ) totBytes ) *100 + "% done" ); } /* Parse the xml-data from our URL. */ // OLD, and works if comment all the above //xr.parse(new InputSource(request.getInputStream())); xr.parse(new InputSource(is)) /* Parsing has finished. */; Can anyone help me at all?? Kind regards, Andy

  • Scheme - Memory System

    - by Eric
    I am trying to make a memory system where you input something in a slot of memory. So what I am doing is making an Alist and the car of the pairs is the memory location and the cdr is the val. I need the program to understand two messages, Read and Write. Read just displaying the memory location selected and the val that is assigned to that location and write changes the val of the location or address. How do I make my code so it reads the location you want it to and write to the location you want it to? Feel free to test this yourself. Any help would be much appreciated. This is what I have: (define make-memory (lambda (n) (letrec ((mem '()) (dump (display mem))) (lambda () (if (= n 0) (cons (cons n 0) mem) mem) (cons (cons (- n 1) 0) mem)) (lambda (msg loc val) (cond ((equal? msg 'read) (display (cons n val))(set! n (- n 1))) ((equal? msg 'write) (set! mem (cons val loc)) (set! n (- n 1)) (display mem))))))) (define mymem (make-memory 100))

    Hello, help me please. There is a list of nodes. <list> <item>1</item> <item>2</item> <item>3</item> <item>4</item> <item>5</item> <item>6</item> <item>7</item> and so on... </list> Need to divide the list of "n" (arbitrary number) equal parts. If the number of nodes is not divided equally, then let the last set of nodes will contain the remainder of the division. For example, if the input list contains 33 elements and the output should have 4 parts with uniformly distributed elements. At the exit to get 3 parts to 9 of elements and one part with 6 elements in the sum of 33.

  • Use Excel VBA to fill out and submit Google Docs form

    - by guitarthrower
    I'm trying to do something like this post but with Excel VBA. I would like to submit a response on a google docs form each time a button is pressed on an Excel add-in. The addin will be an XLA file and written in VBA. I want to be able to collect what features the users are using. If someone has a better solution, I'm open. ---Edit--- This is the form I am trying to write to (excerpt of the code for one of the fields.) <div class="errorbox-good"> <div class="ss-item ss-item-required ss-text"> <div class="ss-form-entry"> <label for="entry_0" class="ss-q-title"> UserName <span class="ss-required-asterisk">*</span> </label> <label for="entry_0" class="ss-q-help"></label> <input type="text" id="entry_0" class="ss-q-short" value="" name="entry.0.single"> </div> </div> </div>

  • Django ModelForm is giving me a validation error that doesn't make sense

    - by River Tam
    I've got a ModelForm based on a Picture. class Picture(models.Model): name = models.CharField(max_length=100) pub_date = models.DateTimeField('date published') tags = models.ManyToManyField('Tag', blank=True) content = models.ImageField(upload_to='instaton') def __unicode__(self): return self.name class PictureForm(forms.ModelForm): class Meta: model = Picture exclude = ('pub_date','tags') That's the model and the ModelForm, of course. def submit(request): if request.method == 'POST': # if the form has been submitted form = PictureForm(request.POST) if form.is_valid(): return HttpResponseRedirect('/django/instaton') else: form = PictureForm() # blank form return render_to_response('instaton/submit.html', {'form': form}, context_instance=RequestContext(request)) That's the view (which is being correctly linked to by urls.py) Right now, I do nothing when the form submits. I just check to make sure it's valid. If it is, I forward to the main page of the app. <form action="/django/instaton/submit/" method="post"> {% csrf_token %} {{ form.as_p }} <input type="submit" value"Submit" /> </form> And there's my template (in the correct location). When I try to actually fill out the form and just validate it, even if I do so correctly, it sends me back to the form and says "This field is required" between Name and Content. I assume it's referring to Content, but I'm not sure. What's my problem? Is there a better way to do this?
