  • O(log n) algorithm to find the element having rank i in union of pre-sorted lists

    - by Eternal Learner
    Given two sorted lists, each containing n real numbers, is there a O(log?n) time algorithm to compute the element of rank i (where i coresponds to index in increasing order) in the union of the two lists, assuming the elements of the two lists are distinct? I can think of using a Merge procedure to merge the 2 lists and then find the A[i] element in constant time. But the Merge would take O(n) time. How do we solve it in O(log n) time?

  • Display post data !

    - by Comii
    I am trying to post data from vb.net application to web service asmx that is located on server! For posting data from vb.net application I am using this code: Public Function Post(ByVal url As String, ByVal data As String) As String Dim vystup As String = Nothing Try 'Our postvars Dim buffer As Byte() = Encoding.ASCII.GetBytes(data) 'Initialisation, we use localhost, change if appliable Dim WebReq As HttpWebRequest = DirectCast(WebRequest.Create(url), HttpWebRequest) 'Our method is post, otherwise the buffer (postvars) would be useless WebReq.Method = "POST" 'We use form contentType, for the postvars. WebReq.ContentType = "application/x-www-form-urlencoded" 'The length of the buffer (postvars) is used as contentlength. WebReq.ContentLength = buffer.Length 'We open a stream for writing the postvars Dim PostData As Stream = WebReq.GetRequestStream() 'Now we write, and afterwards, we close. Closing is always important! PostData.Write(buffer, 0, buffer.Length) PostData.Close() 'Get the response handle, we have no true response yet! Dim WebResp As HttpWebResponse = DirectCast(WebReq.GetResponse(), HttpWebResponse) 'Let's show some information about the response Console.WriteLine(WebResp.StatusCode) Console.WriteLine(WebResp.Server) 'Now, we read the response (the string), and output it. Dim Answer As Stream = WebResp.GetResponseStream() Dim _Answer As New StreamReader(Answer) 'Congratulations, you just requested your first POST page, you 'can now start logging into most login forms, with your application 'Or other examples. vystup = _Answer.ReadToEnd() Catch ex As Exception MessageBox.Show(ex.Message) End Try Return vystup.Trim() & vbLf End Function Now how i can retrieve this data in asmx service?

  • Assign a unique client ID to each <rich:dataTable /> row?

    - by Dolph Mathews
    I'm relatively new to working with the UI in Seam, so I'm hoping there is something simple I can replace the three instances of UNIQUE_ID with in the following example (such as #{object.uniqueId}). The goal is to have a <rich:dataTable /> wherein each row has the ability to show/hide a <rich:modalPanel /> with more details about the particular object instance. <rich:dataTable var="object" value="#{bean.myObject}"> <rich:column> <h:outputText value="#{object.summary}" /> </rich:column> <rich:column> <a onclick="Richfaces.showModalPanel('UNIQUE_ID');" href="#">Show Details in ModalPanel</a> <a4j:form> <rich:modalPanel id="UNIQUE_ID" > <a onclick="Richfaces.hideModalPanel('UNIQUE_ID');" href="#">Hide This ModalPanel</a> <h:outputText value="#{object.details}" /> </rich:modalPanel> </a4j:form> </rich:column> </rich:dataTable> If I only had one link/modalPanel pair, this would obviously be trivial, but I don't know what to do within the scope of the <rich:dataTable />'s iteration. Also, in case it complicates things further, the page will also contain many <rich:dataTable />'s, each implementing this behavior.

  • How to stop IE7 clearing floats because of width property

    - by Andy Hume
    I have a containing element with a number of floated elements in it. That containing element also has a percentage width value applied to it. In IE7, content following the element containing the floats is cleared because of the width value which gives it hasLayout (I think!). I don't want the containing element to haveLayout, but I do need it to have an explicit width. Is there a way of working around this problem in IE7, effectively forcing hasLayout=false.

  • Django: Overriding the save() method: how do I call the delete() method of a child class

    - by Patti
    The setup = I have this class, Transcript: class Transcript(models.Model): body = models.TextField('Body') doPagination = models.BooleanField('Paginate') numPages = models.PositiveIntegerField('Number of Pages') and this class, TranscriptPages(models.Model): class TranscriptPages(models.Model): transcript = models.ForeignKey(Transcript) order = models.PositiveIntegerField('Order') content = models.TextField('Page Content', null=True, blank=True) The Admin behavior I’m trying to create is to let a user populate Transcript.body with the entire contents of a long document and, if they set Transcript.doPagination = True and save the Transcript admin, I will automatically split the body into n Transcript pages. In the admin, TranscriptPages is a StackedInline of the Transcript Admin. To do this I’m overridding Transcript’s save method: def save(self): if self.doPagination: #do stuff super(Transcript, self).save() else: super(Transcript, self).save() The problem = When Transcript.doPagination is True, I want to manually delete all of the TranscriptPages that reference this Transcript so I can then create them again from scratch. So, I thought this would work: #do stuff TranscriptPages.objects.filter(transcript__id=self.id).delete() super(Transcript, self).save() but when I try I get this error: Exception Type: ValidationError Exception Value: [u'Select a valid choice. That choice is not one of the available choices.'] ... and this is the last thing in the stack trace before the exception is raised: .../django/forms/models.py in save_existing_objects pk_value = form.fields[pk_name].clean(raw_pk_value) Other attempts to fix: t = self.transcriptpages_set.all().delete() (where self = Transcript from the save() method) looping over t (above) and deleting each item individually making a post_save signal on TranscriptPages that calls the delete method Any ideas? How does the Admin do it? UPDATE: Every once in a while as I'm playing around with the code I can get a different error (below), but then it just goes away and I can't replicate it again... until the next random time. Exception Type: MultiValueDictKeyError Exception Value: "Key 'transcriptpages_set-0-id' not found in " Exception Location: .../django/utils/datastructures.py in getitem, line 203 and the last lines from the trace: .../django/forms/models.py in _construct_form form = super(BaseInlineFormSet, self)._construct_form(i, **kwargs) .../django/utils/datastructures.py in getitem pk = self.data[pk_key]

  • General method for making sub arrays around a particular element

    - by JJ
    What is a quick, elegant way of using MatLab to form a subarray around a particular element? Element are selected randomly from the data, so you can't take a subarray in the normal way (it has to be generalized for the elements that are selected). What I mean is, forming an array for example 5x5 or 7x7 or something, where the middle element is the one you want.

I'm just wondering if anyone has found a temporary workaround. Thanks in advance, - Scott

  • Random Pairings that don't Repeat

    - by Andrew Robinson
    This little project / problem came out of left field for me. Hoping someone can help me here. I have some rough ideas but I am sure (or at least I hope) a simple, fairly efficient solution exists. Thanks in advance.... pseudo code is fine. I generally work in .NET / C# if that sheds any light on your solution. Given: A pool of n individuals that will be meeting on a regular basis. I need to form pairs that have not previously meet. The pool of individuals will slowly change over time. For the purposes of pairing, (A & B) and (B & A) constitute the same pair. The history of previous pairings is maintained. For the purpose of the problem, assume an even number of individuals. For each meeting (collection of pairs) and individual will only pair up once. Is there an algorithm that will allow us to form these pairs? Ideally something better than just ordering the pairs in a random order, generating pairings and then checking against the history of previous pairings. In general, randomness within the pairing is ok.

  • Link click does nothing after ajax switching?

    - by Neil
    An odd case I'm trying to figure out here. I'm trying to design a mailbox system, and making some of the options ajax-y. Here's the scenario: We have a page with 2 tabs, inbox and compose. Inbox is a essentially a list of links of the form mailbox.php?msg=xxx. Clicking on the inbox or compose tabs does an ajax switch. So, let's say we're on an message page: mailbox.php?msg=123 I click on "compose" - it ajax switches to a compose form. I change my mind, click on "inbox" - it goes back to a list of messages. Note, the url has not changed at this point (all has been done through ajax). I click on the same message as before. It should go back into that message. However, nothing happens! The url it should go to (mailbox.php?msg=123) IS the url showing in the address bar, but, due to the earlier ajax activity, it's showing the inbox. Thoughts on how to resolve this? And, out of curiosity, an explanation? Normally, clicking on a link that takes you to a page you're already on will reload the page. Thanks!

  • Why isn't this simple PHP/MySQL code working?

    - by Sammy
    I am very new to php/mysql and this is causing me to loose hairs, I am trying to build a multi level site navigation. In this part of my script I am readying the sub and parent categories coming from a form for insertion into the database: // get child categories $catFields = $_POST['categories']; if (is_array($catFields)) { $categories = $categories; for ($i=0; $i<count($catFields); $i++) { $categories = $categories . $catFields[$i]"; } } // get parent category $select = mysql_query ("SELECT parent FROM categories WHERE id = $categories"); while ($return = mysql_fetch_assoc($select)) { $parentId = $return['parent']; } The first part of my script works fine, it grabs all the categories that the user has chosen to assign a post by checking the checkboxes in a form and readies it for insertion into the database. But the second part does not work and I can't understand why. I am trying to match a category with a parent that is stored in it's own table, but it returns nothing even though the categories all have parents. Can anyone tell me why this is? p.s. The $categories variable contains the sub category id.

  • Noob LINQ - reading, filtering XML with XDocument

    - by user316117
    I'm just learning XDocument and LINQ queries. Here's some simple XML (which doesn't look formatted exactly right in this forum in my browser, but you get the idea . . .) <?xml version="1.0" encoding="utf-8"?> <quiz xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.example.com/name XMLFile2.xsd" title="MyQuiz1"> <q_a> <q_a_num>1</q_a_num> <q_>Here is question 1</q_> <_a>Here is the answer to 1</_a> </q_a> <q_a> <q_a_num>2</q_a_num> <q_>Here is question 2</q_> <_a>Here is the answer to 2</_a> </q_a> </quiz> I can iterate across all elements in my XML file and display their Name, Value, and NodeType in a ListBox like this, no problem: XDocument doc = XDocument.Load(sPath); IEnumerable<XElement> elems = doc.Descendants(); IEnumerable<XElement> elem_list = from elem in elems select elem; foreach (XElement element in elem_list) { String str0 = "Name = " + element.Name.ToString() + ", Value = " + element.Value.ToString() + ", Nodetype = " + element.NodeType.ToString(); System.Windows.Controls.Label strLabel = new System.Windows.Controls.Label(); strLabel.Content = str0; listBox1.Items.Add(strLabel); } ...but now I want to add a "where" clause to my query so that I only select elements with a certain name (e.g., "qa") but my element list comes up empty. I tried . . . IEnumerable<XElement> elem_list = from elem in elems where elem.Name.ToString() == "qa" select elem; Could someone please explain what I'm doing wrong? (and in general are there some good tips for debugging Queries?) Thanks in advance!

  • What's the difference between reflow and repaint?

    - by Jon Raasch
    I'm a little unclear on the difference between reflow + repaint (if there's any difference at all) Seems like reflow might be shifting the position of various DOM elements, where repaint is just rendering a new object. E.g. reflow would occur when removing an element and repaint would occur when changing its color. Is this true?

  • InfoPath FormControl on STA worker thread

    - by Rob Ford
    I have a .NET class that exposes two public methods: one to create an InfoPath form and another to Export to one of the supported formats. I’m using the Microsoft FormControl to do this. It’s hosted by a Form that does not get displayed. I get called by a Winforms app, but on an MTA worker thread instead of the UI thread. So I create an STA thread and execute on that, which works exactly once and then results in this exception: System.InvalidOperationException was unhandled Message="Unable to get the window handle for the 'FormControl' control. Windowless ActiveX controls are not supported." Source="System.Windows.Forms" StackTrace: at System.Windows.Forms.AxHost.EnsureWindowPresent() at System.Windows.Forms.AxHost.InPlaceActivate() at System.Windows.Forms.AxHost.TransitionUpTo(Int32 state) at System.Windows.Forms.AxHost.CreateHandle() at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.AxHost.EndInit() at InfoPathCreateStaThreadTest.FormControlHost.InitializeComponent() in C:\Windows\Temp\InfoPathCreateStaThreadTest\InfoPathCreateStaThreadTest\FormControlHost.Designer.cs:line 65 After some experimenting, I started to suspect this is a message pumping problem. I then came across this, which makes me more strongly suspect so: http://blogs.msdn.com/cbrumme/archive/2004/02/02/66219.aspx I tried various methods of pumping messages with no luck. I should mention that the alternative of automating the InfoPath app is not viable unless I can figure out how to hide the app. Any help would be much appreciated.

  • jQuery UI Dialog and Textarea Focus Issue

    - by Gimli
    I'm working on a modal comment system using jQuery and jQuery UI, but I'm having some issues with focus. I have a series of divs inside the modal to switch between Login and Add comment, as below: <div id="modal" title="Loading"> <div id="modalContent"></div> <div id="modalLogin"> <div class="loginBox"></div> <div class="addCommentBox"></div> <div class="commentReview"></div> </div> </div> Inside of the addCommentBox div, I've got the comment code: <form action="/comments/add" class="addCommentForm" name="addCommentForm" method="post"> <textarea name="content" class="addCommentContent"></textarea> <button value="Add Comment" type="submit" class="commentPost"/> <button value="Clear Comment" type="submit" id="clearComment"/> </form> The issue is that about half the time after opening the dialog the textarea inside the addCommentBox div doesn't react to keyboard inputs when selected. The mouse works correctly and will allow text to be selected, but keyboard control does nothing. I have no event listeners on the textarea. I've got some on the buttons, but they are targeting only the buttons. The only thing that happens in the HTML seems to be the fact that every time I click on the modal, the z-index increases for the overall modal div. I have set the addCommentBox div to have a z-index of 9999, greater than the z-index of the modal. Any suggestions or directions to research would be greatly appreciated. Thanks!
