    - by d.andreykiv
    Hi. I need to submit an email address with a "+" sign and validate in on server. But server receives email like "[email protected]" as "aaa [email protected]". I send all data as POST request with following code NSURL* url = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@", url, @"/signUp"]]; NSString *post = [NSString stringWithFormat:@"&email=%@&userName=%@&password=%@", user.email, user.userName, user.password]; NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:NO]; NSData* data = [self sendRequest:url postData:postData]; post variable before encoding has value &[email protected]&userName=Asdfasdfadsfadsf&password=sdfasdf after encoding it is same &[email protected]&userName=Asdfasdfadsfadsf&password=sdfasdf Method I use to send request looks like following code: -(id) sendRequest:(NSURL*) url postData:(NSData*)postData { // Create request NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]]; [request setURL:url]; [request setHTTPMethod:@"POST"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Current-Type"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setHTTPBody:postData]; NSURLResponse *urlResponse; NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:nil]; [request release]; return data; }

  • Updating a listitem in an ASPX page in SharePoint Designer

    - by Andy
    Hey All, Right now I'm using SharePoint Designer to create a new aspx page. I am using a data view to display information from a list. One of the fields in the list is a choice field. I was wondering if there was anyway that I could display all of the other fields but allow one field in the list to be edited on the page without adding an edit link. Ideally, I would like a user to go in and be able to edit a field value (hopefully in a drop down list) within a data view without being redirected to the list or a form. I'm thinking there is a way to do this through javascript to embed inside the HTML or through a workflow of some sort. I'm new to javascript and don't know how to do this. I have tried to insert a drop down list and provide a data source for it but it will only show all of the field values in the list. Thus, I am unable to display the choice options, show the current value in the listitem and edit/update the listitem. Hopefully this makes sense. Can anyone help me out here? Thanks a lot, Andy

  • How can I remove a JPanel from a JFrame?

    - by Roman
    Recently I asked here how to add a new JPanel to JFrame. The answer helped me to get a working code. But not I have a related question: "How can I remove an old JPanel". I need that because of the following problem. A new JPanel appears appears when I want (either time limit is exceeded or user press the "Submit" button). But in several seconds some element of the old JPanel appears together with the component of the new JPanel. I do not understand why it happens. I thought that it is because I have to other threads which update the window. But the first thread just add the old panel once (so, it should be finished). And in the second thread I have a loop which is broken (so, it also should be finished). Here is my code: private Thread controller = new Thread() { public void run() { // First we set the initial pane (for the selection of partner). SwingUtilities.invokeLater(new Runnable() { public void run() { frame.getContentPane().add(generatePartnerSelectionPanel()); frame.invalidate(); frame.validate(); } }); // Update the pane for the selection of the parnter. for (int i=40; i>0; i=i-1) { final int sec = i; SwingUtilities.invokeLater(new Runnable() { public void run() { timeLeftLabel.setText(sec + " seconds left."); } }); try {Thread.sleep(1000);} catch (InterruptedException e) {} if (partnerSubmitted) {break;} } // For the given user the selection phase is finished (either the time is over or form was submitted). SwingUtilities.invokeLater(new Runnable() { public void run() { frame.getContentPane().add(generateWaitForGamePanel()); frame.invalidate(); frame.validate(); } }); } };

  • anti-if campaign

    - by Andrew Siemer
    I recently ran against a very interesting site that expresses a very interesting idea - the anti-if campaign. You can see this here at www.antiifcampaign.com. I have to agree that complex nested IF statements are an absolute pain in the rear. I am currently on a project that up until very recently had some crazy nested IFs that scrolled to the right for quite a ways. We cured our issues in two ways - we used Windows Workflow Foundation to address routing (or workflow) concerns. And we are in the process of implementing all of our business rules utilizing ILOG Rules for .NET (recently purchased by IBM!!). This for the most part has cured our nested IF pains...but I find myself wondering how many people cure their pains in the manner that the good folks at the AntiIfCampaign suggest (see an example here) by creating numerous amounts of abstract classes to represent a given scenario that was originally covered by the nested IF. I wonder if another way to address the removal of this complexity might also be in using an IoC container such as StructureMap to move in and out of different bits of functionality. Either way... Question: Given a scenario where I have a nested complex IF or SWITCH statement that is used to evaluate a given type of thing (say evaluating an Enum) to determine how I want to handle the processing of that thing by enum type - what are some ways to do the same form of processing without using the IF or SWITCH hierarchical structure? public enum WidgetTypes { Type1, Type2, Type3, Type4 } ... WidgetTypes _myType = WidgetTypes.Type1; ... switch(_myType) { case WidgetTypes.Type1: //do something break; case WidgetTypes.Type2: //do something break; //etc... }

  • Scale an image which is stored as a byte[] in Java

    - by Sergio del Amo
    I upload a file with a struts form. I have the image as a byte[] and I would like to scale it. FormFile file = (FormFile) dynaform.get("file"); byte[] fileData = file.getFileData(); fileData = scale(fileData,200,200); public byte[] scale(byte[] fileData, int width, int height) { // TODO } Anyone knows an easy function to do this? public byte[] scale(byte[] fileData, int width, int height) { ByteArrayInputStream in = new ByteArrayInputStream(fileData); try { BufferedImage img = ImageIO.read(in); if(height == 0) { height = (width * img.getHeight())/ img.getWidth(); } if(width == 0) { width = (height * img.getWidth())/ img.getHeight(); } Image scaledImage = img.getScaledInstance(width, height, Image.SCALE_SMOOTH); BufferedImage imageBuff = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB); imageBuff.getGraphics().drawImage(scaledImage, 0, 0, new Color(0,0,0), null); ByteArrayOutputStream buffer = new ByteArrayOutputStream(); ImageIO.write(imageBuff, "jpg", buffer); return buffer.toByteArray(); } catch (IOException e) { throw new ApplicationException("IOException in scale"); } } If you run out of Java Heap Space in tomcat as I did, increase the heap space which is used by tomcat.

  • rails delete_all exception

    - by Sergei
    Hello, guys! I have some User model, Role model and Assignment model to manage role-based user system. Just like here . So, here some kind of code, to include roles into users form: <% for role in Role.all %> <%= check_box_tag "user[role_ids][]", role.id, @user.roles.include?(role) %> <%=h role.name %><br /> <% end %> And all's working fine for new records and for editing records. But I just want to make possible to restrict deleting Assigment with id=1, cause this Assignment for default root user from migration, who must be admin anyway. Otherwise, I can lose my last admin. So I've tryed to add before_destroy to Assignment.rb model, but it doesn't work. I've noticed, that when I'm editing user and trying to remove his admin role(assignment), the server makes a delete_all method, not destroy method. So, does anybody know how to catch the deleting of Assignment with id=1 through this kind of code? Thanks in advance!

  • Multithreading A Function in VB.Net

    - by Ben
    I am trying to multi thread my application so as it is visible while it is executing the process, this is what I have so far: Private Sub SendPOST(ByVal URL As String) Try Dim DataBytes As Byte() = Encoding.ASCII.GetBytes("") Dim Request As HttpWebRequest = TryCast(WebRequest.Create(URL.Trim & "/webdav/"), HttpWebRequest) Request.Method = "POST" Request.ContentType = "application/x-www-form-urlencoded" Request.ContentLength = DataBytes.Length Request.Timeout = 1000 Request.ReadWriteTimeout = 1000 Dim PostData As Stream = Request.GetRequestStream() PostData.Write(DataBytes, 0, DataBytes.Length) Dim Response As WebResponse = Request.GetResponse() Dim ResponseStream As Stream = Response.GetResponseStream() Dim StreamReader As New IO.StreamReader(ResponseStream) Dim Text As String = StreamReader.ReadToEnd() PostData.Close() Catch ex As Exception If ex.ToString.Contains("401") Then TextBox2.Text = TextBox2.Text & URL & "/webdav/" & vbNewLine End If End Try End Sub Public Sub G0() Dim siteSplit() As String = TextBox1.Text.Split(vbNewLine) For i = 0 To siteSplit.Count - 1 Try If siteSplit(i).Contains("http://") Then SendPOST(siteSplit(i).Trim) Else SendPOST("http://" & siteSplit(i).Trim) End If Catch ex As Exception End Try Next End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim t As Thread t = New Thread(AddressOf Me.G0) t.Start() End Sub However, the 'G0' sub code is not being executed at all, and I need to multi thread the 'SendPOST' as that is what slows the application.

  • Javascript libraries + JQuery plugins contradict? How to debug?

    - by Metafaniel
    This is somewhat a newbie question... I effort everyday to learn, so please understand ;) I'm not the very best expert, but I can do a decent job good looking and functional websites or web applications. My main tools are PHP5, HTML5, CSS2 y 3, a database (SQLite, MySQL) and Javascript and JQuery. I'm not an expert at all in Javascript. I often find interesting JQuery plugins or tutorials and try to mix them up to do the functionality needed. This time I'm mixing maybe too much plugins and js files from different sources. In fact, my app do what I want except for certain behaviors... There are no errors, everything looks fine, but the misbehavior persists. So maybe I need to specify a class I don't know about, or one contradicts another one from another plugin and I just can't understand, for example, why a <button type="button">DON'T submit</button> just submits the form... Anyway, my point is: Do you people know a way to debug this situations??? Is there a generic tool, suggestion, workflow or something to help me understand conflicts or omissions between libraries or plugins??? (Javascript libraries, my own Javascripts and JQuery plugins)??? I hope it is a way! THANKS A LOT FOR YOUR HELP AND COMPREHENSION! =)

  • Capturing stdout from an imported module in wxpython and sending it to a textctrl, without blocking the GUI

    - by splafe
    There are alot of very similar questions to this but I can't find one that applies specifically to what I'm trying to do. I have a simulation (written in SimPy) that I'm writing a GUI for, the main output of the simulation is text - to the console from 'print' statements. Now, I thought the simplest way would be to create a seperate module GUI.py, and import my simulation program into it: import osi_model I want all the print statements to be captured by the GUI and appear inside a Textctrl, which there's countless examples of on here, along these lines: class MyFrame(wx.Frame): def __init__(self, *args, **kwds): <general frame initialisation stuff..> redir=RedirectText(self.txtCtrl_1) sys.stdout=redir class RedirectText: def __init__(self,aWxTextCtrl): self.out=aWxTextCtrl def write(self,string): self.out.WriteText(string) I am also starting my simulation from a 'Go' button: def go_btn_click(self, event): print 'GO' self.RT = threading.Thread(target=osi_model.RunThis()) self.RT.start() This all works fine, and the output from the simulation module is captured by the TextCtrl, except the GUI locks up and becomes unresponsive - I still need it to be accessible (at the very minimum to have a 'Stop' button). I'm not sure if this is a botched attempt at creating a new thread that I've done here, but I assume a new thread will be needed at some stage in this process. People suggest using wx.CallAfter, but I'm not sure how to go about this considering the imported module doesn't know about wx, and also I can't realistically go through the entire simulation architecture and change all the print statements to wx.CallAfter, and any attempt to capture the shell from inside the imported simulation program leads to the program crashing. Does anybody have any ideas about how I can best achieve this? So all I really need is for all console text to be captured by a TextCtrl while the GUI remains responsive, and all text is solely coming from an imported module. (Also, secondary question regarding a Stop button - is it bad form to just kill the simulation thread?). Thanks, Duncan

  • Is there a JavaScript event that fires when a tab index switch is triggered? (TABINDEX does not work for inputs in IFRAME)

    - by treeface
    My specific use case is that I have a WYSIWYG editor which is basically an editable iframe. To the user, however, it looks like a standard-issue textarea. My problem is that I have inputs that sit before and after this editor in the (perceived) tab index and I'd like the user to be able to press tab (or the equivalent on his platform of choice) to get to the WYSIWYG editor when he's in the previous element and shift-tab to get to it when he's in the latter element. I know this can be faked using the key events and checking whether or not the tab key was pressed, but I'm curious if there's a better way. UPDATE. treeface clarified the actual problem in the comments. PROBLEM: In normal case, you can use "TABINDEX" attribute of the <input> element to control that, when tabbing out of "Subject" input field (in an email form), the focus lands on "Body" input field in the e-mail. This is done simply by assigning correctly ordered values to "TABINDEX" attribute of both input fields. The problem is that TABINDEX attribute only orders elements within the same frame. So, if "Body" input field is actually in an internal IFRAME, you can't tab out of "Subject" in the parent frame straight into "Body" in the IFRAME using TABINDEX order.

  • Javascript to fire event when a key pressed on the Ajax Toolkit Combo box.

    - by Paul Chapman
    I have the following drop down list which is using the Ajax Toolkit to provide a combo box <cc1:ComboBox ID="txtDrug" runat="server" style="font-size:8pt; width:267px;" Font-Size="8pt" DropDownStyle="DropDownList" AutoCompleteMode="SuggestAppend" AutoPostBack="True" ontextchanged="txtDrug_TextChanged" /> Now I need to load this up with approx 7,000 records which takes a considerable time, and effects the response times when the page is posted back and forth. The code which loads these records is as follows; dtDrugs = wsHelper.spGetAllDrugs(); txtDrug.DataValueField = "pkDrugsID"; txtDrug.DataTextField = "drugName"; txtDrug.DataSource = dtDrugs; txtDrug.DataBind(); However if I could get an event to fire when a letter is typed instead of having to load 7000 records it is reduced to less than 50 in most instances. I think this can be done in Javascript. So the question is how can I get an event to fire such that when the form starts there is nothing in the drop down, but as soon as a key is pressed it searches for those records starting with that letter. The .Net side of things I'm sure about - it is the Javascript I'm not. Thanks in advance

  • asp.net master page/content page interaction with style sheet

    - by Matt
    Learning how to do a master page in asp.net. Trying to figure out how my style sheet interacts with respects to the master page and content page. I can get HTML tags like body and the style sheet to react. But when I call the ID attribute of a label no styling takes place. What am I missing here as far as interaction? BTW I'm using VS2008 CSS sample: body { height:1200px; width:920px; border-style:solid; border-color:blue; padding:10px 10px 10px 10px; } #toptext1 { position:relative; top:-225px; right:-500px; font-size:22px; font-weight:bold; } From the master page: <body> <form id="form1" runat="server"> <asp:image id="cookNookLogo" ImageUrl="images/Logo.gif" runat="server" AlternateText="CookNook" Width="449px"></asp:image> <p> <asp:Label ID="toptext1" runat="server" Text="Quality Recipes, Hints and Supplies"></asp:Label> </p> From the content page: <%@ Page Language="C#" MasterPageFile="~/CNMasterPage.master" AutoEventWireup="true" CodeFile="Home.aspx.cs" Inherits="Home" Title="Untitled Page" %> <asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server"> <link href="App_Themes/cn/cn.css" rel="stylesheet" type="text/css" /> </asp:Content> When I was doing this without a master page it worked so where am I going wrong with the attributes?

  • Why is TRest in Tuple<T1... TRest> not constrained?

    - by Anthony Pegram
    In a Tuple, if you have more than 7 items, you can provide an 8th item that is another tuple and define up to 7 items, and then another tuple as the 8th and on and on down the line. However, there is no constraint on the 8th item at compile time. For example, this is legal code for the compiler: var tuple = new Tuple<int, int, int, int, int, int, int, double> (1, 1, 1, 1, 1, 1, 1, 1d); Even though the intellisense documentation says that TRest must be a Tuple. You do not get any error when writing or building the code, it does not manifest until runtime in the form of an ArgumentException. You can roughly implement a Tuple in a few minutes, complete with a Tuple-constrained 8th item. I just wonder why it was left off the current implementation? Is it possibly a forward-compatibility issue where they could add more elements with a hypothetical C# 5? Short version of rough implementation interface IMyTuple { } class MyTuple<T1> : IMyTuple { public T1 Item1 { get; private set; } public MyTuple(T1 item1) { Item1 = item1; } } class MyTuple<T1, T2> : MyTuple<T1> { public T2 Item2 { get; private set; } public MyTuple(T1 item1, T2 item2) : base(item1) { Item2 = item2; } } class MyTuple<T1, T2, TRest> : MyTuple<T1, T2> where TRest : IMyTuple { public TRest Rest { get; private set; } public MyTuple(T1 item1, T2 item2, TRest rest) : base(item1, item2) { Rest = rest; } } ... var mytuple = new MyTuple<int, int, MyTuple<int>>(1, 1, new MyTuple<int>(1)); // legal var mytuple2 = new MyTuple<int, int, int>(1, 2, 3); // illegal

  • How to change CSS color values in real-time off a javascript slider?

    - by bflora
    I'm making a page where the user gets a javascript slider that goes from 0 to 100 and can use it to set the opacity of a div on the page. I want the opacity of that div to change in real-time as they work the slider. I've not done this before. What's the best approach? There cursor in the slider displays the slider's current value as you move it. It seems to be that I just need to find a way to display that value in any arbitrary other place on the page so I can display it in the style settings for the div. The .js file that generates the slider has a line that (I think) is setting the current value in the cursor: $(this).children(".ui-slider-handle", context).html(parseInt(settings[index]['default'])); TO get this changing number to display somewhere else at the same time, do I just need to add a div somewhere and then add a line like this? $("#newDivId").children(".ui-slider-handle", context).html(parseInt(settings[index]['default'])); That seems like it would give me the number showing up in a div. How then would I get it into a form I could put into the style settings for a div? If this was a php variable, I would do something like this, style="opacity:<?php print $value ?>;" What would be the .js equivalent?

  • Testing a method used from an abstract class

    - by Bas
    I have to Unit Test a method (runMethod()) that uses a method from an inhereted abstract class to create a boolean. The method in the abstract class uses XmlDocuments and nodes to retrieve information. The code looks somewhat like this (and this is extremely simplified, but it states my problem) namespace AbstractTestExample { public abstract class AbstractExample { public string propertyValues; protected XmlNode propertyValuesXML; protected string getProperty(string propertyName) { XmlDocument doc = new XmlDocument(); doc.Load(new System.IO.StringReader(propertyValues)); propertyValuesXML= doc.FirstChild; XmlNode node = propertyValuesXML.SelectSingleNode(String.Format("property[name='{0}']/value", propertyName)); return node.InnerText; } } public class AbstractInheret : AbstractExample { public void runMethod() { bool addIfContains = (getProperty("AddIfContains") == null || getProperty("AddIfContains") == "True"); //Do something with boolean } } } So, the code wants to get a property from a created XmlDocument and uses it to form the result to a boolean. Now my question is, what is the best solution to make sure I have control over the booleans result behaviour. I'm using Moq for possible mocking. I know this code example is probably a bit fuzzy, but it's the best I could show. Hope you guys can help.

  • Why is this ajax call being made even though it shouldn't be

    - by user2921557
    i have this validation script im working on but cant see why im having an issue. You can see that i have a check = false / true, check before it runs the ajax call. However, even if a field is empty and check is set to false, it is still running the call. so: // JavaScript - Update Password AJAX $(document).ready(function () { // When the form is submitted $('.updatepasswordform').submit(function () { var check = true; // Get the values var password1 = $("input[name=password1]").val(); var password2 = $("input[name=password2]").val(); var newpassword = $("input[name=newpassword]").val(); /* Password Validation */ // If fields are empty if (password1 === '') { check = false; $("input[name=password1]").css('border', 'solid 2px red'); } // If fields are empty if (password2 === '') { check = false; $("input[name=password2]").css('border', 'solid 2px red'); } // If fields are empty if (newpassword === '') { check = false; $("input[name=newpassword]").css('border', 'solid 2px red'); } if (check = true) { $.ajax({ type: "POST", url: "process/updatepassword.php", data: $(".updatepasswordform").serialize(), dataType: "json", success: function (response) { /* Checks for database validation, removed for space saving */ } }); } return false; }); });

  • How can variadic char template arguments from user defined literals be converted back into numeric types?

    - by Pubby
    This question is being asked because of this one. C++11 allows you to define literals like this for numeric literals: template<char...> OutputType operator "" _suffix(); Which means that 503_suffix would become <'5','0','3'> This is nice, although it isn't very useful in the form it's in. How can I transform this back into a numeric type? This would turn <'5','0','3'> into a constexpr 503. Additionally, it must also work on floating point literals. <'5','.','3> would turn into int 5 or float 5.3 A partial solution was found in the previous question, but it doesn't work on non-integers: template <typename t> constexpr t pow(t base, int exp) { return (exp > 0) ? base * pow(base, exp-1) : 1; }; template <char...> struct literal; template <> struct literal<> { static const unsigned int to_int = 0; }; template <char c, char ...cv> struct literal<c, cv...> { static const unsigned int to_int = (c - '0') * pow(10, sizeof...(cv)) + literal<cv...>::to_int; }; // use: literal<...>::to_int // literal<'1','.','5'>::to_int doesn't work // literal<'1','.','5'>::to_float not implemented

  • TicTacToe strategic reduction

    - by NickLarsen
    I decided to write a small program that solves TicTacToe in order to try out the effect of some pruning techniques on a trivial game. The full game tree using minimax to solve it only ends up with 549,946 possible games. With alpha-beta pruning, the number of states required to evaluate was reduced to 18,297. Then I applied a transposition table that brings the number down to 2,592. Now I want to see how low that number can go. The next enhancement I want to apply is a strategic reduction. The basic idea is to combine states that have equivalent strategic value. For instance, on the first move, if X plays first, there is nothing strategically different (assuming your opponent plays optimally) about choosing one corner instead of another. In the same situation, the same is true of the center of the walls of the board, and the center is also significant. By reducing to significant states only, you end up with only 3 states for evaluation on the first move instead of 9. This technique should be very useful since it prunes states near the top of the game tree. This idea came from the GameShrink method created by a group at CMU, only I am trying to avoid writing the general form, and just doing what is needed to apply the technique to TicTacToe. In order to achieve this, I modified my hash function (for the transposition table) to enumerate all strategically equivalent positions (using rotation and flipping functions), and to only return the lowest of the values for each board. Unfortunately now my program thinks X can force a win in 5 moves from an empty board when going first. After a long debugging session, it became apparent to me the program was always returning the move for the lowest strategically significant move (I store the last move in the transposition table as part of my state). Is there a better way I can go about adding this feature, or a simple method for determining the correct move applicable to the current situation with what I have already done?

  • jQuery autocomplete on multiple fields

    Hi all, Surprisingly, I didn't find any answers to my question. I want to make a form on jQuery with two fields. City Code. City Name. and when I enter a city code and go out of the field. I want an autocomplete on the city name. I Installed the jQuery Autocomplete plugin. and I have the following code : $(document).ready(function() { $("#field_localite").autocomplete('admin/ajax/npa', { extraParams: { npa: function() { return $("#field_npa").val(); } } }); $("#field_npa").blur(function() { $("#field_localite").search(); }); }); The problem is that the .search() method. doesnt launch the autocomplete. I'm looking for a method to trigger this autocomplete search on the field. do you know a way or a plugin able to do this search ? thanks in advance BTW : the PHP code behin is totally tested and works, it returns the data when doing the call.

  • How do I DRY up business logic between sever-side Ruby and client-side Javascript?

    - by James A. Rosen
    I have a Widget model with inheritance (I'm using Single-Table Inheritance, but it's equally valid for Class-per-Table). Some of the subclasses require a particular field; others do not. class Widget < ActiveRecord ALL_WIDGET_TYPES = [FooWidget, BarWidget, BazWidget] end class FooWidget < Widget validates_presence_of :color end class BarWidget < Widget # no color field end class BazWidget < Widget validates_presence_of :color end I'm building a "New Widget" form (app/views/widgets/new.html.erb) and would like to dynamically show/hide the color field based on a <select> for widget_type. <% form_for @widget do |f| %> <%= f.select :type, Widget::ALL_WIDGET_TYPES %> <div class='hiddenUnlessWidgetTypeIsFooOrBaz'> <%= f.label :color %> <%= f.text_field :color %> </div> <% end %> I can easily write some jQuery to watch for onChange events on widget_type, but that would mean putting some sort of WidgetTypesThatRequireColor constant in my Javascript. Easy enough to do manually, but it is likely to get disconnected from the Widget model classes. I would prefer not to output Javascript directly in my view, though I have considered using content_for(:js) and have a yield :js in my template footer. Any better ideas?

  • caching previous return values of procedures in scheme

    In Chapter 16 of "The Seasoned Schemer", the authors define a recursive procedure "depth", which returns 'pizza nested in n lists, e.g (depth 3) is (((pizza))). They then improve it as "depthM", which caches its return values using set! in the lists Ns and Rs, which together form a lookup-table, so you don't have to recurse all the way down if you reach a return value you've seen before. E.g. If I've already computed (depthM 8), when I later compute (depthM 9), I just lookup the return value of (depthM 8) and cons it onto null, instead of recursing all the way down to (depthM 0). But then they move the Ns and Rs inside the procedure, and initialize them to null with "let". Why doesn't this completely defeat the point of caching the return values? From a bit of experimentation, it appears that the Ns and Rs are being reinitialized on every call to "depthM". Am I misunderstanding their point? I guess my question is really this: Is there a way in Scheme to have lexically-scoped variables preserve their values in between calls to a procedure, like you can do in Perl 5.10 with "state" variables?

  • Problems with overriding OnPaint and grabbing mouse events in C# UserControl containing other controls

    - by MoreThanChaos
    I've made a control which contains few other controls like PictureBox, Label and TextBox. But I'm having two problems: 1. I tried to paint some things on top of my control and when I'm overriding OnPaint, it results that things I try to draw are under controls that my control contains. Areas on which I would like to draw intersect with controls in ways that are not easy to predict. I mean that it includes something drawn on controls inside as well as on base of control. Is there a simple way to draw something on top of all contents of my control? Setting ForeColor to Transparent isn't a solution that would help me much. 2. I have a problem with grabbing mouse click events when I place my control on a form and add click event handling. It only works when I click on an area not occupied by controls inside. I would like the whole control to react to clicks and other actions like it was one consistent control. How can I redirect/handle these clicks to make them work the way I want? Thanks in advance for any tips

  • PyQt - QLabel inheriting

    - by Ockonal
    Hello, i wanna inherit QLabel to add there click event processing. I'm trying this code: class NewLabel(QtGui.QLabel): def __init__(self, parent): QtGui.QLabel.__init__(self, parent) def clickEvent(self, event): print 'Label clicked!' But after clicking I have no line 'Label clicked!' EDIT: Okay, now I'm using not 'clickEvent' but 'mousePressEvent'. And I still have a question. How can i know what exactly label was clicked? For example, i have 2 edit box and 2 labels. Labels content are pixmaps. So there aren't any text in labels, so i can't discern difference between labels. How can i do that? EDIT2: I made this code: class NewLabel(QtGui.QLabel): def __init__(self, firstLabel): QtGui.QLabel.__init__(self, firstLabel) def mousePressEvent(self, event): print 'Clicked' #myLabel = self.sender() # None =) self.emit(QtCore.SIGNAL('clicked()'), "Label pressed") In another class: self.FirstLang = NewLabel(Form) QtCore.QObject.connect(self.FirstLang, QtCore.SIGNAL('clicked()'), self.labelPressed) Slot in the same class: def labelPressed(self): print 'in labelPressed' print self.sender() But there isn't sender object in self. What i did wrong?
