• How to run unittest for Django?

  - by photon

  I configured properties for my django project under pydev. I can run the django app under pydev or under console window. But I have problems to run unittest under pydev. I cannot run unittest for app under console window either. I guessed it's something related to run configurations of pydev, so I made several trials, but with no success. Once I got messages like this: ImportError: Could not import settings 'D:\django_projects\MyProject' (Is it on sys.path? Does it have syntax errors?): No module named D:\django_projects\MyProject ERROR: Module: MyUnittestFile could not be imported. Another time I got messages like this: ImportError: Could not import settings 'MyProject.settngs' (Is it on sys.path? Does it have syntax errors?): No module named settngs 'ERROR: Module: MyUnittestFile could not be imported. I use pydev 1.5.6 on eclipse and windows xp. Any ideas for this problem? Now I think it's not something related to pydev, thanks for Xavier Ho's suggestion.

• Defining an implementation independent version of the global object in JavaScript

  - by Aadit M Shah

  I'm trying to define the global object in JavaScript in a single line as follows: var global = this.global || this; The above statement is in the global scope. Hence in browsers the this pointer is an alias for the window object. Assuming that it's the first line of JavaScript to be executed in the context of the current web page, the value of global will always be the same as that of the this pointer or the window object. In CommonJS implementations, such as RingoJS and node.js the this pointer points to the current ModuleScope. However, we can access the global object through the property global defined on the ModuleScope. Hence we can access it via the this.global property. Hence this code snippet works in all browsers and in at least RingoJS and node.js, but I have not tested other CommomJS implementations. Thus I would like to know if this code will not yield correct results when run on any other CommonJS implementation, and if so how I may fix it. Eventually, I intend to use it in a lambda expression for my implementation independent JavaScript framework as follows (idea from jQuery): (function (global) { // javascript framework })(this.global || this);

• WM_NCHITTEST and secondary monitor to left of primary monitor

  - by AlanKley

  The described setup with 2nd monitor to left of primary causes WM_NCHITTEST to send negative values which is apparently not supported according to this post. I have a custom control written in win32 that is like a Group control. It has a small clickable area. No MOUSE events are coming to my control when the window containing the custom control lies on a second monitor to the left of the primary monitor. SPY++ shows WM_NCHITTEST messages but no Mouse messages. When window is moved to primary monitor or secondary monitor is positioned to right of primary (all points are positive) then everything works fine. Below is how the WM_NCHITTEST is handled in my custom control. In general I need it to return HTTRANSPARENT so as not to obscure other controls placed inside of it. Anybody have any suggestions what funky coordinate translation I need to do and what to return in response to WM_NCHITTEST to get Mouse messages translated and sent to my control in the case where it is on a 2nd monitor placed to the left of the primary monitor? case WM_NCHITTEST: { POINT Pt = {LOWORD(lP), HIWORD(lP)}; int i; ScreenToClient (hWnd, &Pt); if (PtInRect (&rClickableArea, Pt)) { return(DefWindowProc( hWnd, Msg, wP, lP )); } } lReturn = HTTRANSPARENT; break;

• jQuery code working in Safari and Chrome but not Firefox

  - by Chris Armstrong

  I'm got a site that has a long list of tweets, and as you scroll down the right column follows you down, showing stats on the tweets. (See it in action at http://www.grapevinegame.com . Click 'memorise', then 'skip' to get to the list page. Works in Safari and Chrome). I'm using jQuery to update the top-margin of the right column, increasing it as I scroll down. It seems to be working fine in webkit-based browsers, but doesn't budge in Firefox. Heres the code, the right column element is a div with id = "distance". // Listen for scroll function $(window).scroll(function () { // Calculating the position of the scrollbar var doc = $("body"), scrollPosition = $("body").scrollTop(), pageSize = $("body").height(), windowSize = $(window).height(), fullScroll = (pageSize) - windowSize; percentageScrolled = (scrollPosition / fullScroll); var entries = $("#whispers-list > li").length; // Set position of distance counter $('div#distance').css('margin-top', ($("#whispers-list").height()+$("#latest-whisper").height()+33)*percentageScrolled); // Update distance counter $('#distance-travelled').text(Math.round(distanceTravelled*(1-percentageScrolled))); $('#whispers-list li').each(function(index) { //highlight adjacent whispers if ($('#whispers-list li:nth-child('+(index+1)+')').offset().top >= $('#distance').offset().top && $('#whispers-list li:nth-child('+(index+1)+')').offset().top <= $('#distance').offset().top + $('#distance').height()) { // alert("yup"); $('#whispers-list li:nth-child('+(index+1)+') ul').fadeTo(1, 1); } else { $('#whispers-list li:nth-child('+(index+1)+') ul').fadeTo(1, 0.5); } }); }); Appreciate any help or advice!

• Question about using adaptive layout + print style sheet

  - by Michael

  Hey everyone, In my web design class, we looked at creating different style sheets for different window sizes and using a javascript that detects the window size and loads the right style sheet. In the head, I'm linking to three external style sheets, as well as a link to the javascript file. So the adaptive layout works fine. However... I also need to be able to use a print style sheet with this particular webpage (it's the requirement for this project). The problem is this that the way the javascript was written makes it so that it ignores the print style sheet. When I go to print preview, it ignores the print style sheet and the preview shows me all of my webpage unstyled. It looks like just the html when opened in a browser. I am using the javascript by Kevin Hale at ParticleTree, and I'm sure there are those familiar with this :] http://particletree.com/examples/dynamiclayouts/ I would like to know what needs to be changed so that the print style sheet isn't ignored. I've shown this to my professor. However, her email wasn't clear enough, but I understand that somehow the script is ignoring the print.css and that's why the print preview shows a css-less preview. Since it's the weekend, I won't be able to get an answer until Monday, and I was hoping someone can help me out. Thank you very much! Michael

• How can I create a WebBrowser control (ActiveX / IWebBrowser2) without a UI?

  - by wangminhere

  I cannot figure out how to use the WebBrowser control without having it create a window in the taskbar. I am using the IWebBrowser2 ActiveX control directly because I need to use some of the advanced features like blocking downloading JAVA/ActiveX/images etc. That apparently is not available in the WPF or winforms WebBrowser wrappers (but these wrappers do have the ability to create the control with no UI) Here is my code for creating the control: Type webbrowsertype = Type.GetTypeFromCLSID(Iid_Clsids.CLSID_WebBrowser, true); m_WBWebBrowser2 = (IWebBrowser2)System.Activator.CreateInstance(webbrowsertype); m_WBWebBrowser2.Visible = false; m_WBOleObject = (IOleObject)m_WBWebBrowser2; int iret = m_WBOleObject.SetClientSite(this); iret = m_WBOleObject.SetHostNames("me", string.Empty); tagRECT rect = new tagRECT(0, 0, 0, 0); tagMSG nullMsg = new tagMSG(); m_WBOleInPlaceObject = (IOleInPlaceObject)m_WBWebBrowser2; //INPLACEACTIVATE the WB iret = m_WBOleObject.DoVerb((int)OLEDOVERB.OLEIVERB_INPLACEACTIVATE, ref nullMsg, this, 0, IntPtr.Zero, ref rect); IConnectionPointContainer cpCont = (IConnectionPointContainer)m_WBWebBrowser2; Guid guid = typeof(DWebBrowserEvents2).GUID; IConnectionPoint m_WBConnectionPoint = null; cpCont.FindConnectionPoint(ref guid, out m_WBConnectionPoint); m_WBConnectionPoint.Advise(this, out m_dwCookie); This code works perfectly but it shows a window in the taskbar. If i omit the DoVerb(OLEDOVERB.OLEIVERB_INPLACEACTIVATE) call, then Navigating to a webpage is not working properly. Navigate() will not download everything on the page and it never fires the DocumentComplete event. If I add a DoVerb(OLEIVERB_HIDE) then I get the same behavior as if I omitted the DoVerb(OLEDOVERB.OLEIVERB_INPLACEACTIVATE) call. This seems like a pretty basic question but I couldn't find any examples anywhere.

• IE event callback object JavaScript

  - by Randy Hall

  I may be WAY off on my terminology, so please feel free to correct me. Perhaps this is why I cannot seem to find anything relevant. No libraries, please. I have an event handler, which invokes a callback function. Fancy, right? In IE<9 the this object in the handler is the window. I don't know why, or how to access the correct object. if (document.addEventListener){ element.addEventListener(event, callback, false); } else { element.attachEvent('on' +event, callback); } This part DOES WORK. This part doesn't: function callback(event){ console.log(this); } this in IE is returning [object Window], whereas it returns the element that called the callback function in every other browser. This is cut down significantly from my full script, but this should be everything that's relevant. EDIT This link provided by @metadings How to reference the caller object ("this") using attachEvent is very close. However, there are still two issues. 1) I need to get both the event object and the DOM element calling this function. 2) This event is handled delegation style: there may be child DOM elements firing the event, meaning event.target is not necessarily (and in my case, not typically) the element with the listener.

• Why does my GridSplitter not work at all?

  - by Crippledsmurf

  I'm migrating a WinForms app to WPF. Everything has gone well so far except in relation to my attempts to use GridSplitter which I can never seam to make resize anything at run-time. To make sure it wasn't just my code I attempted to compile the GridSplitter sample from LearnWPF.com and it doesn't appear to work either. I am expecting to see the standard resize cursor when I mouse over the splitter which doesn't happen, and as far as I can see there is no other visual representation of the splitter in the window either. What am I missing here? <Window x:Class="UI.Test" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Test" Height="300" Width="300"> <Grid> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition /> <ColumnDefinition /> </Grid.ColumnDefinitions> <StackPanel Background="#feca00" Grid.Column="0"> <TextBlock FontSize="35" Foreground="#58290A" TextWrapping="Wrap">Left Hand Side</TextBlock> </StackPanel> <GridSplitter/> <Border CornerRadius="10" BorderBrush="#58290A" BorderThickness="5" Grid.Column="1"> <TextBlock FontSize="25" Margin="20" Foreground="#FECA00" TextWrapping="Wrap">Right Hand Side</TextBlock> </Border> </Grid>

• Why are custom events not working for me? (Mootools)

  - by John McCollum

  I've been learning Mootools, but I'm having problems firing custom events. I'm sure it must be something simple, but I can't see it for the life of me. I wrote a simple class to nudge some list items using Fx.Tween. It works perfectly, except that the custom events aren't being triggered, no matter what I try. <script type="text/javascript"> var Pusher = new Class({ Implements: [Events,Options], options: { elements: [] }, initialize: function(options){ this.setOptions(options); this.attachListeners(this.options.elements); }, attachListeners: function(elements){ $$(elements).each(function(el){ $(el).addEvent('mouseover', this.pushIn.bind(el)) .addEvent('mouseout', this.pushOut.bind(el)); }, this); }, pushIn: function(){ this.fireEvent('in'); this.set('tween', {duration: 'short'}); this.tween('paddingLeft', '50px'); }, pushOut: function(){ this.fireEvent('out'); this.set('tween', {duration: 'short'}); this.tween('paddingLeft', '0px'); } }); window.addEvent('domready', function(){ var p = new Pusher({ elements: $$('li') }); p.addEvent('in', function(){ alert('in'); }); p.addEvent('out', function(){ alert('out'); }); }); </script> And in the HTML: <ul id="mylist"> <li>1</li> <li>2</li> <li>3</li> <li>4</li> </ul> I've also tried the following: window.addEvent('domready', function(){ var p = new Pusher({ elements: $$('li'), onIn: function(){ alert('in'); }, onOut: function(){ alert('out'); } }); }); What am I doing wrong?

• What is it that automatically checks config changes (such as those in /etc) into git?

  - by Brandon

  I remember reading on the ubuntu forums some time ago about a program to automatically check configuration changes into version control for you. It was (of course) not Ubuntu-specific. I'm pretty sure it used git, though it may have been svn, or perhaps even able to work with multiple different VCSs. My Googling has turned up nothing, and I'd rather not roll my own script if someone has already done this well. Of course I could just manually check things in, but there are reasons I'd like it done automatically. (I'm actually planning to use this for my LastSession.plist file for Safari, so when the #@$%^*&! thing crashes, and I don't restore everything, and then Leopard crashes, the fact that it has such lousy session management won't mean I lose the dozens of windows with dozens of tabs I had open.)

• highlight the text of the DOM range element,

  - by ganapati

  I am able to highlight the text on the HTML page(rendered through gtkmozembed), which is selected, like below. var range, sel; if (window.getSelection) { sel = window.getSelection(); if (sel.getRangeAt) { range = sel.getRangeAt(0); } document.designMode = "on"; if (range) { sel.removeAllRanges(); sel.addRange(range); } document.execCommand("HiliteColor", false, colour); document.designMode = "off"; } Well,it works very fine.Now i am trying to store the information(startNode, startOffset,endNode, endOffset) about the highlighted text, and next time when i open the same page,highlight the same text. I am able to successfully store the info and retrieve them when the same page opens. And i am trying to highlight the text using following code. var range = document.createRange(); range.setStart(startNode, startOffset); range.setEnd(endNode, endOffset); document.designMode = "on"; range.execCommand("HiliteColor", false, colour); document.designMode = "off"; But it is not working as i am expecting. Can anyone help me to achieve the required? Thanks...

• Recover from inadvertent skip during rebase

  - by Benjol

  I just tried to rebase a very old branch with a minor modification onto my master. There was a problem with merging just one of the three files involved, so I did an unthinking --skip, thinking that it would just skip that file, but as it happened, it seems to have skipped all my changes, and rolled forwards. So now the rebase is finished, and my changes seem to have disappeared. I've seen the question about undoing rebase, but it's all greek to me, I see the reflog, but I don't know which commit the branch was attached to before the rebase. In any case, I don't really need to undo the rebase, I just want to be able to recover the changes in the two files. Is there anyway to do this properly (failing this, I'll just have to restore yesterday's backup of my repository and pick the bits out by hand).

• Scroll to anchor

  I have the following userjs which is intended to remove anchor part of the URL but still jump to it: // ==UserScript== // @name PurgeAnchor // @include * // ==/UserScript== (function() { var reg=/^(.*)\#(.*)$/; var match=reg.exec(location); function ObjectPosition(obj) { var curtop = 0; if(obj.offsetParent) while(1) { curtop += obj.offsetTop; if(!obj.offsetParent) break; obj = obj.offsetParent; } else if(obj.y) curtop += obj.y; return curtop; } if(match) { document.location.replace(match[1]); sessionStorage.setItem("anchor", match[2]); } window.addEventListener("load", (function() { var anchor=sessionStorage.getItem("anchor"); if(anchor!==null) { var obj=document.getElementById(anchor); if(obj===null) { obj=document.getElementsByName(anchor)[0]; } var pos=0; if(obj!==null) { pos=ObjectPosition(obj); window.scrollTo(0, pos); } sessionStorage.removeItem("anchor"); } }), false); })() The problem is that if I have an empty <a> tag with the name set, it fails to jump. obj.scrollIntoView() also fails.

• OpenGL particle system

  - by allan

  I'm really new with OpenGL, so bear with me. I'm trying to simulate a particle system using OpenGl but I can't get it to work, this is what I have so far: #include <GL/glut.h> int main (int argc, char **argv){ // data allocation, various non opengl stuff ............ glutInit(&argc, argv); glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE ); glutInitWindowPosition(100,100); glutInitWindowSize(size, size); glPointSize (4); glutCreateWindow("test gl"); ............ // initial state, not opengl ............ glViewport(0,0,size,size); glutDisplayFunc(display); glutIdleFunc(compute); glutMainLoop(); } void compute (void) { // change state not opengl glutPostRedisplay(); } void display (void) { glClear(GL_COLOR_BUFFER_BIT); glBegin(GL_POINTS); for(i = 0; i<nparticles; i++) { // two types of particles if (TYPE(particle[i]) == 1) glColor3f(1,0,0); else glColor3f(0,0,1); glVertex2f(X(particle[i]),Y(particle[i])); } glEnd(); glFlush(); glutSwapBuffers(); } I get a black window after a couple of seconds (the window has just the title bar before that). Where do I go wrong? Any help would be very much appreciated. Thanks. LE: the x and y coordinates of each particle are within the interval (0,size)

• Javascript: I can get the text of a selection, now how do I get the text outside the selection?

  - by DavidR

  I have a bit of code that returns the text of a selection and I can assign that string to a variable, but now all I need are two variables, one for the text before the selection and one for the text after the selection. Here is the code for getting the selection: function findSelection(){ //returns the selection object. var userSelection; if (window.getSelection) {userSelection = window.getSelection();} // Mozilla Selection object. else if (document.selection){userSelection = document.selection.createRange();} //gets Microsoft Text Range, should be second b/c Opera has poor support for it. if (userSelection.text){return userSelection.text} //for Microsoft Objects. else {return userSelection} //For Mozilla Objects. } Then I find the anchorOffset and focusOffset to find the caret positions. I tried using these to modify a range object, like this: var range = document.createRange(); range.setStart(textdiv,0); range.setEnd(textdiv,5); Where textdiv is a variable holding the last div the user clicked on. The problem is firefox just gives me a "Security error" code: "1000" at the line range.setStart(textdiv,0);. Is there an easier way to go about doing this? I really just need the text and nothing more.

• Receiving client-event on a GtkWindow

  - by fret

  I'm trying to send and receive a client-event using a GtkWindow on the win32 platform. The sending code looks like this: GtkWidget *Wnd; GdkNativeWindow Hnd = #ifdef WIN32 GDK_WINDOW_HWND(Wnd->window); #else GDK_WINDOW_XWINDOW(Wnd->window); #endif GdkEvent *Event = gdk_event_new(GDK_CLIENT_EVENT); // fill out Event params gdk_event_send_client_message(Event, Hnd); Receiving code looks like this: static gboolean MyClientEvent(GtkWidget *widget, GdkEventClient *ev, MyWnd *Wnd) { // breakpoint here... return TRUE; } GtkWidget *Wnd = gtk_window_new(GTK_WINDOW_TOPLEVEL); g_signal_connect( G_OBJECT(Wnd), "client-event", G_CALLBACK(MyClientEvent), this); gtk_widget_add_events(Wnd, GDK_ALL_EVENTS_MASK); I used Spy++ to see the message getting sent, so I know the sending side is ok. The receiving side however doesn't get the client-event. I was expecting my breakpoint in the callback to trigger... but it doesn't. I'm not even sure if a GtkWindow can receive a client-event... from past experience on X11 I thought it was pretty much the same as any other GtkWidget in that respect. Maybe on the win32 platform it's kinda different. But still I'd like to be able to get this working.

• Looping login with Facebook JS SDK and Rails

  - by nafe

  I'm using the Facebook JS SDK for single-sign with my rails app. I translated the php code from the Facebook example (at the bottom of the page under "Single Sign-on with the JavaScript SDK") into ruby. This appeared to be working great but I've noticed one user that gets continual redirects when trying to login. The logs look like: Processing UsersController#login (for X.X.X.X at 2010-05-22 17:25:55) [GET] Redirected to http://myapp.com/ Completed in 0ms (DB: 0) | 302 Found [http://myapp.com/login] (times as many entries as my unfortunate user leaves the browser redirecting in a loop). My client side code includes a callback with the "auth.sessionChange": FB.Event.subscribe('auth.sessionChange', function(response) { if (response.session) { // A user has logged in, and a new cookie has been saved window.location = "/login"; } else { // The user has logged out, and the cookie has been cleared window.location = "/logout"; } }); So it seems to me like this event is continually firing. Although, I can't test this theory because I can't recreate this scenario locally. I don't think it's the rails controller. The code here is just: def login # if first time user create db entry # now redirect back to where the user came from begin redirect_to :back rescue ActionController::RedirectBackError redirect_to root_url end end Does anyone have any idea on what's going on?

• How to save highlighting to a database

  - by vman

  Hi I am trying to highlight a part of the text on my website. This highlighted text will be saved for the specific user in a database and when the document is opened again it will show the previously highlighted text. I assumed I would be using javascript to highlight the text but I cannot seem to find a way to pinpoint where the word is that I am highlighting. function getSelText() { var txt = ''; if (window.getSelection) { txt = window.getSelection(); } else if (document.getSelection) { txt = document.getSelection(); } else if (document.selection) { txt = document.selection.createRange().text; } else return ""; return txt; } I am using that to get the selection but I cannot figure out where the selection is in the text. The biggest annoyance is when I have duplicates within the line or text so if I were to use search then I would find the first instance and not the one I was looking for. So the question is : How do you pinpoint a word or a selection in the entire document?

When I resize the Form of my Device, the Draw method is still called, but doesnt throw an Exception, it looks like this: device.Clear(ClearFlags.Target, Color.Red, 0, 0); device.BeginScene(); // here is out commented code device.EndScene(); device.Present(); In another method, I wrote this: renderToSurface.BeginScene(surfaces[currentIndex]); // here is out commented code renderToSurface.EndScene(Filter.None); and this method seems to throw a nullpointer exception when I resize the window; So my question is: - where to reset / restore / handle the renderToSurface class? (i tried it with the DeviceReset event like following - void OnDeviceReset(object sender, EventArgs e) { renderToSurface = new RenderToSurface(Game.Device, Game.ClientSize.Width, Game.ClientSize.Height, Format.A8R8G8B8, true, DepthFormat.D16); } )

• git doesn't show where code was removed.

  - by Andrew Myers

  So I was tasked at replacing some dummy code that our project requires for historical compatibility reasons but has mysteriously dropped out sometime since the last release. Since disappearing code makes me nervous about what else might have gone missing but un-noticed I've been digging through the logs trying to find in what commit this handful of lines was removed. I've tried a number of things including "git log -S'add-visit-resource-pcf'", git blame, and even git bisect with a script that simply checks for the existence of the line but have been unable to pinpoint exactly where these lines were removed. I find this very perplexing, particularly since the last log entry (obtained by the above command) before my re-introduction of this code was someone else adding the code as well. commit 0b0556fa87ff80d0ffcc2b451cca1581289bbc3c Author: Andrew Date: Thu May 13 10:55:32 2010 -0400 Re-introduced add-visit-resource-pcf, see PR-65034. diff --git a/spike/hst/scheduler/defpackage.lisp b/spike/hst/scheduler/defpackage.lisp index f8e692d..a6f8d38 100644 --- a/spike/hst/scheduler/defpackage.lisp +++ b/spike/hst/scheduler/defpackage.lisp @@ -115,6 +115,7 @@ #:add-to-current-resource-pcf #:add-user-package-nickname #:add-value-criteria + #:add-visit-resource-pcf #:add-window-to-gs-params #:adjust-derived-resources #:adjust-links-candidate-criteria-types commit 9fb10e25572c537076284a248be1fbf757c1a6e1 Author: Bob Date: Sun Jan 17 18:35:16 2010 -0500 update-defpackage for Spike 33.1 Delivery diff --git a/spike/hst/scheduler/defpackage.lisp b/spike/hst/scheduler/defpackage.lisp index 983666d..47f1a9a 100644 --- a/spike/hst/scheduler/defpackage.lisp +++ b/spike/hst/scheduler/defpackage.lisp @@ -118,6 +118,7 @@ #:add-user-package-nickname #:add-value-criteria #:add-vars-from-proposal + #:add-visit-resource-pcf #:add-window-to-gs-params #:adjust-derived-resources #:adjust-links-candidate-criteria-types This is for one of our package definition files, but the relevant source file reflects something similar.

• Detecting Singularities in a Graph

  - by nasufara

  I am creating a graphing calculator in Java as a project for my programming class. There are two main components to this calculator: the graph itself, which draws the line(s), and the equation evaluator, which takes in an equation as a String and... well, evaluates it. To create the line, I create a Path2D.Double instance, and loop through the points on the line. To do this, I calculate as many points as the graph is wide (e.g. if the graph itself is 500px wide, I calculate 500 points), and then scale it to the window of the graph. Now, this works perfectly for most any line. However, it does not when dealing with singularities. If, when calculating points, the graph encounters a domain error (such as 1/0), the graph closes the shape in the Path2D.Double instance and starts a new line, so that the line looks mathematically correct. Example: However, because of the way it scales, sometimes it is rendered correctly, sometimes it isn't. When it isn't, the actual asymptotic line is shown, because within those 500 points, it skipped over x = 2.0 in the equation 1 / (x-2), and only did x = 1.98 and x = 2.04, which are perfectly valid in that equation. Example: In that case, I increased the window on the left and right one unit each. My question is: Is there a way to deal with singularities using this method of scaling so that the resulting line looks mathematically correct? I myself have thought of implementing a binary search-esque method, where, if it finds that it calculates one point, and then the next point is wildly far away from the last point, it searches in between those points for a domain error. I had trouble figuring out how to make it work in practice, however. Thank you for any help you may give!

• sIFR 3 rev 436 - copy link to clipboard

  - by Alan Forsyth

  This was originally a question, but is now a code enhancement, since it's a very minor (but useful) update. When heading (or other) text is used as a link with sIFR 3, you now get the two 'open link / open link in new window' options in the right-click flash context menu for the link. When I came across sIFR for the first time yesterday, I was wanting to copy a header (h2) link to the clipboard, on a site that used sIFR 2.x, and was frustrated that I couldn't. Thanks to the wonders of open source (and well written code), I can suggest the following enhancement to sIFR 3: [In the file flash/sIFR.as, find the section starting with the comment "// Have to set up menu items first!" through to ");" and replace with the following, then add font information to the .fla and export the swf as per the tutorial:] // Have to set up the menu items first! menuItems.push( new ContextMenuItem("Follow link", function() { getURL(sIFR.instance.primaryLink, sIFR.instance.primaryLinkTarget) }), new ContextMenuItem("Open link in new window", function() { getURL(sIFR.instance.primaryLink, "_blank") }), new ContextMenuItem("Copy link to clipboard", function() { System.setClipboard(sIFR.instance.primaryLink) }) ); Now I'm happy... :-) Alan.

• Disable auto resize this page when opening in IE

  - by Stan

  If open yahoo finance chart in IE, the chart will be resized to fit the viewing window, and making the chart viewable without scrolling down. However, this makes the chart become smaller for me. I would like to see original size, which requires me to click the setting bar and change something to make it restore original size. The chart shows original size in Chrome. Is it possible to view original size in IE by passing some parameters in url? I was trying looking into source code but found nothing.

• Javascript: Adding selected text to an array

  - by joeybaker

  My goal: each time a user selects text, and clicks a button, that text gets added to an array. The problem: each time the button is pressed, the all objects of the array get overridden with the currently selected text. I'd really appreciate help changing the behavior so that the selected text doesn't override all previous array items. <script type="text/javascript"> var selects = new Array(); selects.push("1"); function getSelText() { var i = 0; while (i<1) { var txt = [null]; var x = 0; if (window.getSelection) { txt[x] = window.getSelection(); } else if (document.getSelection) { txt[x] = document.getSelection(); } else if (document.selection) { txt[x] = document.selection.createRange().text; } else return; selects.push(txt); x++; i++; }; document.menu.selectedtext.value = selects; } </script> <form class="menu" name="menu"> <input type="button" value="highlight" class="highlightButton" onmousedown="getSelText()"/> <textarea name="selectedtext" rows="5" cols="20"></textarea> </form> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
