  • C# How to commit a TextBox?

    - by Jake
    Hi, In a form, I have a TextBox Binding an Object on its member property "Title". Along with it is a "Save" button to test the binding. Seems like the underlying object property does not get updated unless the textbox loses focus. But there no form.ActiveControl.Blur() for use. Besides, this does not seem like a sound hack. Anyway to do this better? Thanks. EDIT: Sorry for not being clear. My question is in the title: "How to commit a TextBox". I use the term "commit" from the DataGridView commit and BindingSource commit. And it's in WinForms. (Have never worked with WPF, so it didn't occur to me. Sorry). The actual scenario I have is I have a bunch of TextBox binded to property of a single Object. The user enters values in all the TextBox and when the user clicks save (toolbar button), the last TextBox is still in focus (or in editing mode) hence the save will not capture the last value in the last textbox. I want to find the correct way to "commit" the textbox value just before saving. Thanks.

  • Django admin interface upload failing on request data read error

    - by Jake
    Hi All, This is an updated version of an old question I asked. I've now done a lot more testing, plus the old question got hijacked. I'm getting a request data read error when trying to upload files to the Django admin interface. Files under about 150k work, but bigger files always fail and almost always at around 192k (that's 3 chunks) completed, sometimes at around 160k. The Exception I get is below. File "/usr/lib/python2.4/site-packages/django/http/multipartparser.py", line 405, in read return self._file.read(num_bytes) IOError: request data read error I've tried Chrome and Firefox on Windows and Firefox on Mac - Same results. I can upload to other sites so I don't think it's my connection. I'm running python 2.4, django 1.1, mod_wsgi, on CentOS (a media temple DV server) Locally it's fine (Django development server) Everything I've found on this issue says it's a mod_python issue and that changing to mod_wsgi will fix it, but I am running mod_wsgi. Can anyone help?

  • C# System.Xml.Serialization Self-nested elements

    - by Jake
    Hi, I am trying to deserialize <graph> <node> <node> <node></node> </node> </node> <node> <node> <node></node> </node> </node> </graph> with [XmlRoot("graph")] class graph { List<node> _children = new List<node>(); [XmlElement("node")] public Node[] node { get { return _children.ToArray(); } set { foreach(node n in value) children.add(n) } }; } class node { List<node> _children = new List<node>(); [XmlElement("node")] public Node[] node { get { return _children.ToArray(); } set { foreach(node n in value) children.add(n) } }; } but it keeps saying object not created, null reference encountered when trying to set children nodes. What is wrong above? Thanks in advance~

  • jQuery test if element1 is child of element2

    - by Jake
    Does anyone know a good way to test if one element, stored in a var, is the child of another, also stored in a var? I don't need element1.isChildOf('selector'), that's easy. I need element1.isChildOf(element2) element2.find(element1).size() > 0 Does not seem to work. I don't want to have to write a plugin the uses .each to test each child if I can avoid it.

  • Perceptron Classification and Model Training

    - by jake pinedo
    I'm having an issue with understanding how the Perceptron algorithm works and implementing it. cLabel = 0 #class label: corresponds directly with featureVectors and tweets for m in range(miters): for point in featureVectors: margin = answers[cLabel] * self.dot_product(point, w) if margin <= 0: modifier = float(lrate) * float(answers[cLabel]) modifiedPoint = point for x in modifiedPoint: if x != 0: x *= modifier newWeight = [modifiedPoint[i] + w[i] for i in range(len(w))] w = newWeight self._learnedWeight = w This is what I've implemented so far, where I have a list of class labels in answers and a learning rate (lrate) and a list of feature vectors. I run it for the numbers of iterations in miter and then get the final weight at the end. However, I'm not sure what to do with this weight. I've trained the perceptron and now I have to classify a set of tweets, but I don't know how to do that. EDIT: Specifically, what I do in my classify method is I go through and create a feature vector for the data I'm given, which isn't a problem at all, and then I take the self._learnedWeight that I get from the earlier training code and compute the dot-product of the vector and the weight. My weight and feature vectors include a bias in the 0th term of the list so I'm including that. I then check to see if the dotproduct is less than or equal to 0: if so, then I classify it as -1. Otherwise, it's 1. However, this doesn't seem to be working correctly.

  • Clipboard Debugging

    - by Jake Pearson
    In the olden times of .NET 1.1, I could use the SoapFormatter to find out exactly what was getting serialized when I copied an object into the clipboard. Fast forward to 2010, and I tried to do the same trick. It turns out the SoapFormatter does not support generics. Is there an alternative way to find out exactly what binary objects are serialized into the clipboard? For example lets say I have this class: public class Foo { public List<Goo> Children; } If I send an instance of it to the clipboard, I would like to take a look at what is in the clipboard to see if it's children list was included or not. Update: I was finally able to find the over copied field with the debugger. Visual Studio did it's job.

  • How do I sort an ArrayList lexicographically?

    - by Jake
    I am trying to sort an ArrayList of Strings that represent card values. So, some cards contain letters ("King") and some contain Strings containing only a number ("7"). I know to use Collections.sort, but it only sorts Strings that contain letters. How do I get the ArrayList to be sorted by number as well as alphabetically?

  • Mercurial Remove History

    - by Jake Pearson
    Is there a way in mercurial to remove old changesets from a database? I have a repository that is 60GB and that makes it pretty painful to do a clone. I would like to trim off everything before a certain date and put the huge database away to collect dust.

  • fixed vertical positioning of css within an iframe

    - by Jake Rider
    I am trying to get my bottom header to stick to the bottom of the screen inside of my iframe application and have it always appear in view for the user even when the page is scrolling. I have no control over the outer iframe as it is on a different domain. The header itself must be inside of the iframe as I have no control outside the iframe. The iframe always expands to the height of its contents so that it has no scrollbars, but the bar still has to be visible in the viewport at all times.

  • Can I stop the page from 'scrolling' back to the top when a user clicks on a tab (with Rails not Jav

    - by Jake
    Ive built a webpage with 'tabs' using rails. When a user clicks a tab, a new page loads. I want to format it so the tabs are always in the same place on the page as a user clicks them. This happens as long as the user has not scrolled down on the page. If a user has scrolled down, clicking on the tab will refresh the page and it is no longer scrolled down - which make clicking the tabs look bad. Is there a way to keep the spot on the page where the user has scrolled down, without using Javascript? If it must be done with Javascript, any suggestions? T

  • Threading is slow and unpredictable?

    - by Jake
    I've created the basis of a ray tracer, here's my testing function for drawing the scene: public void Trace(int start, int jump, Sphere testSphere) { for (int x = start; x < scene.SceneWidth; x += jump) { for (int y = 0; y < scene.SceneHeight; y++) { Ray fired = Ray.FireThroughPixel(scene, x, y); if (testSphere.Intersects(fired)) sceneRenderer.SetPixel(x, y, Color.Red); else sceneRenderer.SetPixel(x, y, Color.Black); } } } SetPixel simply sets a value in a single dimensional array of colours. If I call the function normally by just directly calling it it runs at a constant 55fps. If I do: Thread t1 = new Thread(() => Trace(0, 1, testSphere)); t1.Start(); t1.Join(); It runs at a constant 50fps which is fine and understandable, but when I do: Thread t1 = new Thread(() => Trace(0, 2, testSphere)); Thread t2 = new Thread(() => Trace(1, 2, testSphere)); t1.Start(); t2.Start(); t1.Join(); t2.Join(); It runs all over the place, rapidly moving between 30-40 fps and sometimes going out of that range up to 50 or down to 20, it's not constant at all. Why is it running slower than it would if I ran the whole thing on a single thread? I'm running on a quad core i5 2500k.

  • Switching/Linking to another external stylesheet in a .js file using Ruby on Rails

    - by Jake
    Im learning JQuery from a Sitepoint Book but Im trying to apply all the lessons to a Rails App. In one lesson, we are taught how to switch to a different stylesheet if the browser window is resized beyond a certain point. Here's the javascript code: if ($('body').width() > 900) { $('<link rel="stylesheet" href="wide.css" type="text/css" />') .appendTo('head'); } else { $('link[href=wide.css]').remove(); } Rails doesn't seem to want to link to the new stylesheet using 'link rel'. I've tried using the Rails helper: <%= stylesheet_link_tag 'base', :media => 'screen' %> but that doesn't work in a .js file. How do I link to an external stylesheet in a .js file using Ruby? Can I use Ruby on Rails code in a .js file? Thanks.

  • List of generic algorithms and data structures

    - by Jake Petroules
    As part of a library project, I want to include a plethora of generic algorithms and data structures. This includes algorithms for searching and sorting, data structures like linked lists and binary trees, path-finding algorithms like A*... the works. Basically, any generic algorithm or data structure you can think of that you think might be useful in such a library, please post or add it to the list. Thanks! (NOTE: Because there is no single right answer I've of course placed this in community wiki... and also, please don't suggest algorithms which are too specialized to be provided by a generic library) The List: Data structures AVL tree B-tree B*-tree B+-tree Binary tree Binary heap Binary search tree Linked lists Singly linked list Doubly linked list Stack Queue Sorting algorithms Binary tree sort Bubble sort Heapsort Insertion sort Merge sort Quicksort Selection sort Searching algorithms

  • Where the hell is shared_ptr!?!

    - by Jake
    I am so frustrated right now after several hours trying to find where the hell is shared_ptr located at. None of the examples i see show complete code to include the headers for shared_ptr (and working). simply stating "std" "tr1" and "" is not helping at all! I have downloaded boosts and all but still it doesn't show up! Can someone help me by telling exactly where to find it? Thanks for letting me vent my frustrations!

  • What is the easiest way to reference libraries in Qt projects?

    - by Jake Petroules
    I have two Qt4 Gui Application projects and one shared library project, all referenced under a .pro file with the "subdirs" template. So, it's like: exampleapp.pro app1.pro app2.pro sharedlib.pro Now, what I want to do is reference sharedlib from app1 and app2 so that every time I run app1.exe, I don't have to manually copy sharedlib.dll from its own folder to app1.exe's folder. I could set PATH environment variable in the projects window, but this isn't very portable. I've looked at putting the LIBS variable in the app1.pro file, but I'm not sure if that refers to statically linked libraries only - I've tried it with various syntaxes and it doesn't seem to work with shared libs.

  • How can I get the text that was clicked on in Javascript?

    - by Jake
    Does anyone know if it is possible with javascript to to tell the position of a mouse click in some text? I know it's easy to get the x,y coordinates, but I'm wanting the position in the text. For example if I clicked inside <p>foo bar</p> I want to be able to tell that the click was on/after the 5th character. Or that foo b is before the click and ar is after it. By the way, I'm using jQuery too, I'm happy with pure JS and solutions that use jQ. Thanks in advance.

  • Getting past Salesforce trigger governors

    - by Jake
    I'm trying to write an "after update" trigger that does a batch update on all child records of the record that has just been updated. This needs to be able to handle 15k+ child records at a time. Unfortunately, the limit appears to be 100, which is so far below my needs it's not even close to acceptable. I haven't tried splitting the records into batches of 100 each, since this will still put me at a cap of 10k updates per trigger execution. (Maybe I could just daisy-chain triggers together? ugh.) Does anyone know what series of hoops I can jump through to overcome yet another ridiculously short-sighted limitation by this awful development "platform"?

  • iPhone question: How can I add a button to a tableview cell?

    - by Jake
    Hi guys, Little background, the table view is filled by a fetchedResultsController which fills the table view with Strings. Now I'm trying to add a button next to each String in each tableview cell. So far, I've been trying to create a button in my configureCell:atIndexPath method and then add that button as a subview to the table cell's content view, but for some reason the buttons do not show up. Below is the relevant code. If anyone wants more code posted, just ask and I'll put up whatever you want. Any help is greatly appreciated. - (void)configureCell:(UITableViewCell *)cell atIndexPath:(NSIndexPath *)indexPath { // get object that has the string that will be put in the table cell Task *task = [fetchedResultsController objectAtIndexPath:indexPath]; //make button UIButton *button = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain]; [button setTitle:@"Check" forState:UIControlStateNormal]; [button setTitle:@"Checked" forState:UIControlStateHighlighted]; //set the table cell text equal to the object's property cell.textLabel.text = [task taskName]; //addbutton as a subview [cell.contentView addSubview:button]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell. [self configureCell:cell atIndexPath:indexPath]; return cell; }
