• Jquery - Convert ascii chars back to HTML

  - by sdmiller

  I am reading data from an html file to load into a div. The problem I am having is, the program that writes the html files is converting to <br /> SO when I execute $('#items').load('/News/list.aspx'); it displays as a string on my page instead of reading it as a page break. I have tried to read the above file into a variable to do a string replace on the <br /> but it doesn't seem to work. Any suggestions?

• IE's responseXML.getElementsByTagName() unable to handle non English character ?

  - by trix

  I have a javascript that does this (http is your XMLHttpRequest object) var r = http.responseXML.getElementsByTagName('item'); The issue is variable r is always an empty list if the response contains non-English character (r.length is 0). The response header is correctly set Content-Type: text/xml;charset=ISO-8859-1 This is what the response from the webserver looks like <?xml version='1.0' encoding='UTF-8'?> <d> <r> <item value="jmob" label="John Möb"/> </r> </d> It happens only in IE (both IE6 and IE8), works in Firefox and Chrome. If items contain only English characters, it works fine. Is there a workaround for this ?

• Change right-click context menu options in VS2008

  - by Mark Ursino

  When I right-click in my class library, I get some quick options to create things, like an Item from the popup list (New Item...), a User Control, etc. E.g. Now in my web app project, I'd like to be able to get the User Control listed in the right-click menu just like Component and Class, so I don't have to click New Item... then choose it from there. Is there a way to do this in the configuration? I can't seem to figure it out in VS.

• Localizing a plist with grouped data

  - by Robert Altman

  Is there a way to localize a plist that contain hierarchical or grouped data? For instance, if the plist contains: Book 1 (dictionary) Key (string) Name (string) Description (localizable string) Book 2 (dictionary) Key (string) Name (string) Description (localizable string) (etcetera...) For the sake of the example, the Key and Name should not be translated (and preferably should not be duplicated in multiple localized property lists). Is there a mechanism for providing localizations for the localizable Description field without localizing the entire property list? The only other strategy that came to my mind is to store a lookup key in the description field and than use that to retrieve the localized text via NSLocalizedString(...) Thanks.

• write.table in R screws up header when has rownames

  - by Yannick Wurm

  Hello, check this example: > a = matrix(1:9, nrow = 3, ncol = 3, dimnames = list(LETTERS[1:3], LETTERS[1:3])) > a A B C A 1 4 7 B 2 5 8 C 3 6 9 the table displays correctly. There are two different ways of writing it to file... write.csv(a, 'a.csv') which gives as expected: "","A","B","C" "A",1,4,7 "B",2,5,8 "C",3,6,9 and write.table(a, 'a.txt') which screws up "A" "B" "C" "A" 1 4 7 "B" 2 5 8 "C" 3 6 9 indeed, an empty tab is missing.... which is a pain in the butt for downstream things. Is this a bug or a feature? Is there a workaround? (other than write.table(cbind(rownames(a), a), 'a.txt', row.names=FALSE) Cheers, yannick

• TYPO3: How do i render tt_content text elements in my own extensions?

  - by arturh

  I'm currently writing a TYPO3 extension which is configured with a list of tt_content UID's. These point to content elements of type "text" and i want to render them by my extension. Because of TYPO3s special way of transforming the text you enter in the rich text editing when it enters the database, and again transforming it when it is rendered to the frontend, i can not just output the database contents of the "bodytext" field. I want to render these texts as they would usually get rendered by TYPO3. How do I do that?

• Some input regarding Dojo (smooth css change on mouseover)

  - by Andy Walpole

  I've been playing around with Dojo over the last couple of days. The script below changes the background position of the list item when the mouse is over the link. dojo.query('a[class=main-menu-link]').forEach(function(linkTwo) { dojo.connect(linkTwo, "onmouseover", function(evt) { dojo.query('#main-menu ul li').forEach(function(linkThree) { dojo.style(linkThree, { "backgroundPosition": "right center", }); }); You can see it in action in the right hand side menu: http://www.mechanic-one.suburban-glory.com/ I'm trying to work out the best of way of giving it a smooth transition between the two states... I've been looking on the Dojo documentation page but I'm not sure what is the best way of approaching it.

  My question is close to this one: Digester: Extracting node name Even with the answer, I can't find out.

• How to override the attr_protected?

  - by KandadaBoggu

  I have STI implementation as follows: class Automobile < ActiveRecord::Base end class Car < Automobile end class Truck < Automobile end class User < ActiveRecord::Base has_many :automobiles accepts_nested_attributes_for :automobiles end I am creating a list of automobiles for a user. For each automobile, the UI sets the type field and the properties associated with the automobile.While form submission, the type field is ignored as it is a protected attribute. How do I work around this issue? Is there a declarative way to unprotect a protected attribute?

• xVal ignoring fields that are hidden

  - by gmcalab

  I have a form where a user can toggle receiving funds either via check or via electronic transfer. When they choose either way in a list box, the respective part of the form hides. If they choose electronic transfer only bank info fields show, if they choose via check only address info shows and the bank fields are hidden. Well, since they choose one way or another I want to, not validate for something that is hidden. (Client Side) Is there a way to set xVal to only validate fields that are not visible? I tried to override validate with the following but no dice... $('#EditPayment').validate({ elementwhichishidden: { required: function(element) { return ($(element).parent().parent().css('display') != 'none'); } } });

• Creating ActionEvent object for CustomButton in Java

  - by Crystal

  For a hw assignment, we were supposed to create a custom button to get familiar with swing and responding to events. We were also to make this button an event source which confuses me. I have an ArrayList to keep track of listeners that would register to listen to my CustomButton. What I am getting confused on is how to notify the listeners. My teacher hinted at having a notify and overriding actionPerformed which I tried doing, but then I wasn't sure how to create an ActionEvent object looking at the constructor documentation. The source, id, string all confuses me. Any help would be appreciated. Thanks! code: import java.awt.*; import java.awt.event.*; import javax.swing.*; import java.util.List; import java.util.ArrayList; public class CustomButton { public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { public void run() { CustomButtonFrame frame = new CustomButtonFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); } }); } public void addActionListener(ActionListener al) { listenerList.add(al); } public void removeActionListener(ActionListener al) { listenerList.remove(al); } public void actionPerformed(ActionEvent e) { System.out.println("Button Clicked!"); } private void notifyListeners() { ActionEvent event = new ActionEvent(CONFUSED HERE!!!!; for (ActionListener action : listenerList) { action.actionPerfomed(event); } } List<ActionListener> listenerList = new ArrayList<ActionListener>(); } class CustomButtonFrame extends JFrame { // constructor for CustomButtonFrame public CustomButtonFrame() { setTitle("Custom Button"); CustomButtonSetup buttonSetup = new CustomButtonSetup(); this.add(buttonSetup); this.pack(); } } class CustomButtonSetup extends JComponent { public CustomButtonSetup() { ButtonAction buttonClicked = new ButtonAction(); this.addMouseListener(buttonClicked); } // because frame includes borders and insets, use this method public Dimension getPreferredSize() { return new Dimension(200, 200); } public void paintComponent(Graphics g) { Graphics2D g2 = (Graphics2D) g; // first triangle coords int x[] = new int[TRIANGLE_SIDES]; int y[] = new int[TRIANGLE_SIDES]; x[0] = 0; y[0] = 0; x[1] = 200; y[1] = 0; x[2] = 0; y[2] = 200; Polygon firstTriangle = new Polygon(x, y, TRIANGLE_SIDES); // second triangle coords x[0] = 0; y[0] = 200; x[1] = 200; y[1] = 200; x[2] = 200; y[2] = 0; Polygon secondTriangle = new Polygon(x, y, TRIANGLE_SIDES); g2.drawPolygon(firstTriangle); g2.setColor(firstColor); g2.fillPolygon(firstTriangle); g2.drawPolygon(secondTriangle); g2.setColor(secondColor); g2.fillPolygon(secondTriangle); // draw rectangle 10 pixels off border int s1[] = new int[RECT_SIDES]; int s2[] = new int[RECT_SIDES]; s1[0] = 5; s2[0] = 5; s1[1] = 195; s2[1] = 5; s1[2] = 195; s2[2] = 195; s1[3] = 5; s2[3] = 195; Polygon rectangle = new Polygon(s1, s2, RECT_SIDES); g2.drawPolygon(rectangle); g2.setColor(thirdColor); g2.fillPolygon(rectangle); } private class ButtonAction implements MouseListener { public void mousePressed(MouseEvent e) { System.out.println("Click!"); firstColor = Color.GRAY; secondColor = Color.WHITE; repaint(); } public void mouseReleased(MouseEvent e) { System.out.println("Released!"); firstColor = Color.WHITE; secondColor = Color.GRAY; repaint(); } public void mouseEntered(MouseEvent e) {} public void mouseExited(MouseEvent e) {} public void mouseClicked(MouseEvent e) {} } public static final int TRIANGLE_SIDES = 3; public static final int RECT_SIDES = 4; private Color firstColor = Color.WHITE; private Color secondColor = Color.DARK_GRAY; private Color thirdColor = Color.LIGHT_GRAY; }

• What is the ISO C++ way to directly define a conversion function to reference to array?

  - by ben

  According to the standard, a conversion function has a function-id operator conversion-type-id, which would look like, say, operator char(&)[4] I believe. But I cannot figure out where to put the function parameter list. gcc does not accept either of operator char(&())[4] or operator char(&)[4]() or anything I can think of. Now, gcc seems to accept (&operator char ())[4] but clang does not, and I am inclined to not either, since it does not seem to fit the grammar as I understand it. I do not want to use a typedef because I want to avoid polluting the namespace with it.

• A Better way? Finding ASP.NET controls, finding their id

  - by CSharp

  I have a method that finds all the controls, iterates through them, determines if they are a textbox,drop down list, etc.. retrieves their ID name, and depending on the ID name it will set a boolean statement (thus I would know if that section of the form is complete, and will email to a certain group of people) unfortunetly this is done with too many if statements and was wondering if I could get some help making this more manageable protected void getEmailGroup() { Control[] allControls = FlattenHierachy(Page); foreach (Control control in allControls) { if (control.ID != null) { if (control is TextBox) { TextBox txt = control as TextBox; if (txt.Text != "") { if (control.ID.StartsWith("GenInfo_")) { GenInfo = true; } if (control.ID.StartsWith("EmpInfo_")) { EmpInfo = true; } } } if (control is DropDownList) { DropDownList lb = control as DropDownList; if (lb.SelectedIndex != -1) { if (control.ID.StartsWith("GenInfo_")) { GenInfo = true; } if (control.ID.StartsWith("EmpInfo_")) { EmpInfo = true; } } } } } }

• R: how to make a unique set of names from a vector of strings?

  - by Mike Dewar

  Hi, I have a vector of strings. Check out my vector, it's awesome: > awesome [1] "a" "b" "c" "d" "d" "e" "f" "f" I'd like to make a new vector that is the same length as awesome but where, if necessary, the strings have been uniqueified. For example, a valid output of my desired function would be > awesome.uniqueified [1] "a" "b" "c" "d.1" "d.2" "e" "f.1" "f.2" Is there an easy, R-thonic and beautiful way to do this? I should say my list in real life (it's not called awesome) contains 25000ish mircoarray probeset identifiers. I'm always nervous when I embark on writing little generic functions (which I'm sure I could do) as I'm sure some R guru has come across this problem in the past, nailed it with some incredible algorithm that doesn't even have to store more than half an element in the vector. I'm just not sure what they might have called it. Probably not uniqueify.

• Android::Confused about image sizes in a website

  - by Legend

  I was testing my website inside the Android emulator with the Droid Skin (240 dpi). I have the following css: #container { position: relative; width: 854px; height: 480px; background: #000; margin: auto; } #container li { position: relative; list-style: none; width: 201px; height: 110px; padding-left: 10px; padding-top:10px; padding-bottom:10px; overflow: hidden; float: left; z-index: 2; } The display is not what I expected obviously because I am defining everything in px (when I should have been using dip but css does not allow dip). How can I convert my px to something that is suitable for Android? Any suggestions?

• Linq to NHibernate - How to return a parent object with only certain child objects included

  - by vakman

  Given a simplified model like the following: public class Enquiry { public virtual DateTime Created { get; set; } public virtual Sender Sender { get; set; } } public class Sender { public virtual IList<Enquiry> Enquiries { get; set; } } How can you construct a Linq to Nhibernate query such that it gives you back a list of senders and their enquiries where the enquiries meet some criteria. I have tried something like this: return session.Linq<Enquiry>() .Where(enquiry => enquiry.Created < DateTime.Now) .Select(enquiry => enquiry.Sender) In this case I get an InvalidCastException saying you can't cast type Sender to type Enquiry. Any pointers on how I can do this without using HQL?

• .net, C# Interface between Business Logic and DAL

  - by Joel

  I'm working on a small application from scratch and using it to try to teach myself architecture and design concepts. It's a .NET 3.5, WPF application, and I'm using Sql Compact Edition as my data store. I'm working on the business logic layer, and have just now begun to write the DAL. I'm just using SqlCeComamnds to send over simple queries and SqlCeResultSet to get at the results. I'm starting to design my Insert and Update methods, and here's the issue - I don't know the best way to get the necessary data from the BLL into the DAL. Do I pass in a generic collection? Do I have a massive parameter list with all the data for the database? Do I simply pass in the actual business object (thus tying my DAL to the conrete stuff in the BLL?). I thought about using interfaces - simply passing IBusinessObjectA into the DAL, which provides the simplicity I'm looking for without tying me TOO tightly to current implementations. What do you guys think?

• Find a control by String from asp.net Web service

  - by jphenow

  Well since it seems relatively difficult to send the object of a WebControl over JSON using jquery.ajax() I've decided to send the name of the control as a string because I know how to do that. Then I promptly realized that, from a web service, I don't actually know how to search for a control by ID name. Since its a service I can't seem to get Control.FindControl() to work so does anyone have ideas or suggestions? All I'm trying to do is call a databind() on my radcombobox. Thanks in advance! For any of you that knows anything about asp.net/rad controls - I'm basically updating a database and want the radcombobox to be in sync with that database again after adding something, before I autoselect what was just added. Other than databind do i have to call anything to refresh that list? Thanks again!

• Possible to bind an event listener to a (hypothetical) onChangeInnerHTML event?

  - by DustMason

  In my app, I have an OL tag whose contents are changed by various other dynamic events. Is there some way to put a listener on that OL so that I can execute a function whenever its contents are altered in any way? In this example I need to update a count of items in the list which appears in another spot in the interface. I am using jQuery if that helps. The contents of the OL are being changed with OL.append() and LI.remove(), in case those methods have some special events that I don't know about Thanks!
