  • Fancy Box doesnt work please help

    - by JL
    I recently came across fancy box located here, I've followed every step in the instructions perfectly, but it doesn't work, anyone know what might be the problem? Here is a sample of my page source: Included the links to scripts as required, and CSS: <script src="jquery.fancybox-1.2.1/jquery.fancybox/jquery-1.3.2.min.js" type="text/javascript"></script> <script src="jquery.fancybox-1.2.1/jquery.fancybox/jquery.fancybox-1.2.1.js" type="text/javascript"></script> <link href="jquery.fancybox-1.2.1/jquery.fancybox/jquery.fancybox.css" rel="stylesheet" type="text/css" /> <link href="css/main.css" rel="stylesheet" type="text/css" /> Then this should simply work: <a id="single_image" href="images/279641.jpg"><img src="images/279641.jpg" /></a> But it doesn't seem to do anything except open the image in a new window. Any suggestions, and thanks in advance.

  • Why This Maintainability Index Increase?

    - by Timothy
    I would be appreciative if someone could explain to me the difference between the following two pieces of code in terms of Visual Studio's Code Metrics rules. Why does the Maintainability Index increase slightly if I don't encapsulate everything within using ( )? Sample 1 (MI score of 71) public static String Sha1(String plainText) { using (SHA1Managed sha1 = new SHA1Managed()) { Byte[] text = Encoding.Unicode.GetBytes(plainText); Byte[] hashBytes = sha1.ComputeHash(text); return Convert.ToBase64String(hashBytes); } } Sample 2 (MI score of 73) public static String Sha1(String plainText) { Byte[] text, hashBytes; using (SHA1Managed sha1 = new SHA1Managed()) { text = Encoding.Unicode.GetBytes(plainText); hashBytes = sha1.ComputeHash(text); } return Convert.ToBase64String(hashBytes); } I understand metrics are meaningless outside of a broader context and understanding, and programmers should exercise discretion. While I could boost the score up to 76 with return Convert.ToBase64String(sha1.ComputeHash(Encoding.Unicode.GetBytes(plainText))), I shouldn't. I would clearly be just playing with numbers and it isn't truly any more readable or maintainable at that point. I am curious though as to what the logic might be behind the increase in this case. It's obviously not line-count.

  • Excel 2007 and Unicode

    - by pjlasl
    I have an israeli spreadsheet reading right to left. When I read the values (using VBA) it places a question mark (?) at the beginning and end of the text, in other words it wraps the text with the question mark (ie ?0123456?). If you type Range("A2").value or .value2 or .text the results are the same. Any idea on how to prevent this?

  • Changing classes on multiple divs when selecting specific radio buttons

    - by Rob
    Hey everyone I got a javascript problem I can't seem to find a specific solution for on the web. What I want to be able to do is select one of the radio buttons and have that change the class of #home-right to either .rackmount or .shipping and add the class of .displaynone to the type of dimensions I don't want shown. <div id="home-right" class="rackmount"> <h4 class="helvneuebcn">Case Finder</h4> <div class="cta-options"> <input type="radio" value="Shipping and Storage" name="" checked> Shipping and Storage<br/> <input type="radio" value="Rackmount Enclosures" name=""> Rackmount Enclosures<br/> </div> <div class="shipping-dimensions displaynone"> <div class="dimensions"><input type="text" class="size"><span class="helvneuemd">H x </span></div> <div class="dimensions"><input type="text" class="size"><span class="helvneuemd">W x </span></div> <div class="dimensions"><input type="text" class="size"><span class="helvneuemd">L</span></div> </div> <div class="rackmount-dimensions"> <div class="dimensions"><input type="text" class="size"><span class="helvneuemd">U Height x </span></div> <div class="dimensions"><input type="text" class="size"><span class="helvneuemd">Rack Depth</span></div> </div> <div class="clear"></div> <input type="button" value="Submit" class="findcase"> </div>

  • How to build C# object from a FormCollection with complex keys

    - by ob
    i have a javascript object, obj, that gets passed to an mvc action via a $.post() like so: var obj = { Items: [{ Text: "", Value: { Property1: "", Property2: "" }, { Text: "", Value: { Property1: "", Property2: "" }] }; $.post('MyAction', obj, function() {}); the action signature looks like this: public ActionResult MyAction(FormCollection collection) { } i need to be able to build an object from the FormCollection, however i'm running into an issue where the keys are in the form: "Items[0][Text]" "Items[0][Value][Property1]" "Items[0][Value][Property2]" "Items[1][Text]" "Items[1][Value][Property1]" "Items[1][Value][Property2]" i'm wondering if there's a clean way to build the desired C# object from the given FormCollection. i understand that i could change the action method signature to take in the type of object i'm interested in, but that was presenting its own issues.

  • problem with jquery : minipulating val() property of element

    - by P4ul
    Hi, Please help! I have some form elements in a div on a page: <div id="box"> <div id="template"> <div> <label for="username">Username</label> <input type="text" class="username" name="username[]" value="" / > <label for="hostname">hostname</label> <input type="text" name="hostname[]" value=""> </div> </div> </div> using jquery I would like to take a copy of #template, manipulate the values of the inputs and insert it after #template so the result would look something like: <div id="box"> <div id="template"> <div> <label for="username">Username</label> <input type="text" class="username" name="username[]" value="" / > <label for="hostname">hostname</label> <input type="text" name="hostname[]" value=""> </div> </div> <div> <label for="username">Username</label> <input type="text" class="username" name="username[]" value="paul" / > <label for="hostname">hostname</label> <input type="text" name="hostname[]" value="paul"> </div> </div> I am probably going about this the wrong way but the following test bit of javascript code run in firebug on the page does not seem to change the values of the inputs. var cp = $('#template').clone(); cp.children().children().each( function(i,d){ if( d.localName == 'INPUT' ){ $(d).val('paul'); //.css('background-color', 'red'); } }); $("#box").append(cp.html()); although if I uncomment "//.css('background-color', 'red');" the inputs will turn red.

  • Jquery - custom countdown

    - by matthewsteiner
    So I found this countdown at http://davidwalsh.name/jquery-countdown-plugin, I altered it a little bit: jQuery.fn.countDown = function(settings,to) { settings = jQuery.extend({ duration: 1000, startNumber: $(this).text(), endNumber: 0, callBack: function() { } }, settings); return this.each(function() { //where do we start? if(!to && to != settings.endNumber) { to = settings.startNumber; } //set the countdown to the starting number $(this).text(to); //loopage $(this).animate({ 'fontSize': settings.endFontSize },settings.duration,'',function() { if(to > settings.endNumber + 1) { $(this).text(to - 1).countDown(settings,to - 1); } else { settings.callBack(this); } }); }); }; Then I have this code: $(document).ready(function(){ $('.countdown').countDown({ callBack: function(me){ $(me).text('THIS IS THE TEXT'); } }); }); I don't mind taking everything out of the "animate" loop; I'd prefer that since nothing needs to be animated. (I don't need the font size to change). So everything's working to a point. I have a span with class countdown and whatever is in it when the page is refreshed goes down second by second. However, I need it to be formatted in M:S format. So, my two questions: 1) What can I use instead of animate to take care of the loop yet maintain the callback 2) How (where in the code should I) can I play with the time format? Thanks.

  • Static Javascript files not loaded in Express app

    - by Dave Long
    I have an express app that has a bunch of static javascript files that aren't being loaded even though they are registered in my app.js file. Even public scripts (like jQuery: http://ajax.googleapis.com/ajax/libs/jquery/1.6.3/jquery.min.js) aren't processing. I can see the script tags in the generated html, but none of the functionality runs and I can't see the files loading in the web inspector. Here is the code that I have: app.js var express = require('express') var app = module.exports = express.createServer(); // Configuration var port = process.env.PORT || 3000; app.configure(function(){ app.set('views', __dirname + '/views'); app.set('view engine', 'jade'); app.use(express.bodyParser()); app.use(express.methodOverride()); app.use(app.router); app.use(express.static(__dirname + '/public')); }); app.configure('development', function(){ app.use(express.errorHandler({ dumpExceptions: true, showStack: true })); }); app.configure('production', function(){ app.use(express.errorHandler()); }); // Routes app.get('/manage/new', function(req, res){ res.render('manage/new', { title: 'Create a new widget' }); }) app.listen(port); console.log("Express server listening on port %d in %s mode", app.address().port, app.settings.env); /views/manage/layout.jade !!! 5 html(lang="en") head title= title link(rel="stylesheet", href="/stylesheets/demo.css") link(rel="stylesheet", href="/stylesheets/jquery.qtip.css") script(type="text/javascript", href="http://ajax.googleapis.com/ajax/libs/jquery/1.6.3/jquery.min.js") body!= body script(type="text/javascript", href="/javascripts/jquery.formalize.js") script(type="text/javascript", href="/javascripts/jquery.form.js") script(type="text/javascript", href="/javascripts/jquery.qtip.js") script(type="text/javascript", href="/javascripts/formToWizard.js") script(type="text/javascript", href="/javascripts/widget.js") /views/manage/new.jade h1= title div(style="float:left;") form(action="/manage/generate", method="post", enctype="multipart/form-data", name="create-widget") .errors fieldset legend Band / Album Information fieldset legend Social Networks fieldset legend Download All of my javascript files are stored in /public/javascripts and all of my static CSS files are being served up just fine.

  • Using java2d user space measurements with TextLayout and LineBreakMeasurer

    - by Andrew Wheeler
    I have a java2d image defined in user space (mm) to print an identity card. The transformation to pixels is by using an AffineTransform for the required DPI (Screen or print). I want to wrap text across several lines but the the TextLayout does not respect user space co-ordinates. private void drawParagraph(Graphics2D g2d, Rectangle2D area, String text) { LineBreakMeasurer lineMeasurer; AttributedString string = new AttributedString(text); AttributedCharacterIterator paragraph = string.getIterator(); int paragraphStart = paragraph.getBeginIndex(); int paragraphEnd = paragraph.getEndIndex(); FontRenderContext frc = g2d.getFontRenderContext(); lineMeasurer = new LineBreakMeasurer(paragraph, frc); float breakWidth = (float)area.getWidth(); float drawPosY = (float)area.getY(); float drawPosX = (float)area.getX(); lineMeasurer.setPosition(paragraphStart); while (lineMeasurer.getPosition() < paragraphEnd) { TextLayout layout = lineMeasurer.nextLayout(breakWidth); drawPosY += layout.getAscent(); layout.draw(g2d, drawPosX, drawPosY); drawPosY += layout.getDescent() + layout.getLeading(); } } The above code determines font metrics using user space sizing of the Font and thus turn out rather large. The font size is calculated as best vertical fit for the number of lines in an area with the calculation as below. E.g. attr.put(TextAttribute.SIZE, (geTextArea().getHeight() / noOfLines - LINE_SPACING) ); When using g2d.drawString("Some text to display", x, y); the font size appears correct. Does anyone have a better way of doing text layout in user space co-ords?

  • Can Flash AS3 listbox data contain variable info?

    - by Anne
    I'm populating a listbox like this: dp.addItem( {label:"red dress", data:"OV4MP/23OL.swf"} ); Instead of data:"OV4MP/23OL.swf", I would like to make part of the data file name a variable from a dynamic textbox named centerPt that belongs to the parent movieclip, so I did this: dp.addItem( {label:"red dress", data:"OV4MP/23"+MovieClip(parent.parent).centerPt.text+".swf"} ); When I trace the selectedItem.data using: trace("you have selected: "+ overlays.selectedItem.data); trace(MovieClip(parent.parent).centerPt.text); I'm getting: you have selected: OV4MP/23.swf. What I should get is OV4MP/23OL.swf. It is not picking up what is in the dynamic centerPt.text field which are the letters OL eventhough that text field is tracing correctly. Is it possible that data can not hold a variable? Thank you in advance for any help. Anne

  • Why is my Python OpenGL render2DTexture function so slow?

    - by Barakat
    SOLVED: The problem was actually using time.time() every CPU cycle to see whether the next frame should be drawn or not. The time it takes to execute time.time() was having an impact on the FPS. I made this function for drawing 2D textures as images in a 2D view in my OpenGL application. After doing some testing I found that it takes up 1-2 fps per texture. I know I am probably doing something wrong in this code. Any ideas? I am limiting the FPS to 60. Edit: When I disable the texture rendering it adds about 15% fps back. When I disabled text rendering it adds about 15% fps back. When i disable both barely any fps is consumed anymore. IE: 20 out of 60 fps with both on. 30 out of 60 when one is disabled. 58 out of 60 when both are disabled. When rendering the text on a button ( the control I'm using to test this ), it only "prepares" the text when the button label is set. Updated code, still running at the same speed but still works the same: def render2DTexture( self, texture, rect, texrect ): glEnable( GL_TEXTURE_2D ) glBindTexture( GL_TEXTURE_2D, texture ) glBegin( GL_QUADS ) glTexCoord2f( texrect.left, texrect.bottom ) glVertex2i( rect.left, self.windowSize[1] - rect.top ) glTexCoord2f( texrect.right, texrect.bottom ) glVertex2i( rect.left + rect.right, self.windowSize[1] - rect.top ) glTexCoord2f( texrect.right, texrect.top ) glVertex2i( rect.left + rect.right, self.windowSize[1] - ( rect.top + rect.bottom ) ) glTexCoord2f( texrect.left, texrect.top ) glVertex2i( rect.left, self.windowSize[1] - ( rect.top + rect.bottom ) ) glEnd() glDisable( GL_TEXTURE_2D ) def prepareText( self, text, fontFace, color ): self.loadFont( fontFace ) bmp = self.fonts[ fontFace ].render( text, 1, color ) return ( pygame.image.tostring( bmp, 'RGBA', 1 ), bmp.get_width(), bmp.get_height() ) def renderText( self, pText, position ): glRasterPos2i( position[0], self.windowSize[1] - ( position[1] + pText[2] ) ) glDrawPixels( pText[1], pText[2], GL_RGBA, GL_UNSIGNED_BYTE, pText[0] )

  • Adding StyleSheets Programmatically in Asp.Net

    - by Braveyard
    I want to add StyleSheets programmatically in the head section but one of the examples I saw seemed to need to many lines of code to add just one style sheet even though I may need a lot: Example Code: HtmlLink css = new HtmlLink(); css.Href = "css/fancyforms.css"; css.Attributes["rel"] = "stylesheet"; css.Attributes["type"] = "text/css"; css.Attributes["media"] = "all"; Page.Header.Controls.Add(css); I also use Page.Header.RenderControl() method but it didn't work either. Object null something error was thrown. I also used Page.Header.InnerHtml and InnerText += "<link .... "/> things but they threw the Literal error which is I think common error. I used this code : List<Literal> cssFiles = new List<Literal>(); cssFiles.Add(new Literal() { Text = @"<link href=""" + ResolveUrl("~/Resources/Styles/MainMaster/MainDesign.css") + @""" type=""text/css"" rel=""stylesheet"" />" }); cssFiles.Add(new Literal() { Text = @"<link href=""" + ResolveUrl("~/Resources/Styles/MainMaster/MainLayout.css") + @""" type=""text/css"" rel=""stylesheet"" />" }); AddStyleRange(cssFiles); private void AddStyleRange(List<Literal> cssFiles) { foreach (Literal item in cssFiles) { this.Header.Controls.Add(item); } } It worked at first but when I change the pages it stopped working. I am using Master Page and I am writing these codes on Master.cs file and also some people recommended to use this.Header instead of Page.Header but when I built it throws an error which says I cannot declare that like this. It shouldn't be that hard to add many styles. It is getting complicated.

  • shared library in C

    - by sasayins
    Hi, I am creating a shared library in C but don't know what is the correct implementation of the source codes. I want to create an API like for example, printHello, int printHello( char * text ); This printHello function will call another function: In source file, libprinthello.c, void printHello( char * text ) { printHi(); printf("%s", text); } Since this printHello function is the interface for the user or application: In header file libprinthello.h, extern void printHello( char * text); Then in the source file of the printHi function, printhi.c void printHi() { printf("Hi\n"); } Then my problem is, since printHello is the only function that I want to expose in the user, what implementation should I do in printHi function?

  • Swing: Scroll to bottom of JScrollPane, conditionally on current viewport location

    - by I82Much
    Hi all, I am attempting to mimic the functionality of Adium and most other chat clients I've seen, wherein the scrollbars advance to the bottom when new messages come in, but only if you're already there. In other words, if you've scrolled a few lines up and are reading, when a new message comes in it won't jump your position to the bottom of the screen; that would be annoying. But if you're scrolled to the bottom, the program rightly assumes that you want to see the most recent messages at all times, and so auto-scrolls accordingly. I have had a bear of a time trying to mimic this; the platform seems to fight this behavior at all costs. The best I can do is as follows: In constructor: JTextArea chatArea = new JTextArea(); JScrollPane chatAreaScrollPane = new JScrollPane(chatArea); // We will manually handle advancing chat window DefaultCaret caret = (DefaultCaret) chatArea.getCaret(); caret.setUpdatePolicy(DefaultCaret.NEVER_UPDATE); In method that handles new text coming in: boolean atBottom = isViewAtBottom(); // Append the text using styles etc to the chatArea if (atBottom) { scrollViewportToBottom(); } public boolean isAtBottom() { // Is the last line of text the last line of text visible? Adjustable sb = chatAreaScrollPane.getVerticalScrollBar(); int val = sb.getValue(); int lowest = val + sb.getVisibleAmount(); int maxVal = sb.getMaximum(); boolean atBottom = maxVal == lowest; return atBottom; } private void scrollToBottom() { chatArea.setCaretPosition(chatArea.getDocument().getLength()); } Now, this works, but it's janky and not ideal for two reasons. By setting the caret position, whatever selection the user may have in the chat area is erased. I can imagine this would be very irritating if he's attempting to copy/paste. Since the advancement of the scroll pane occurs after the text is inserted, there is a split second where the scrollbar is in the wrong position, and then it visually jumps towards the end. This is not ideal. Before you ask, yes I've read this blog post on Text Area Scrolling, but the default scroll to bottom behavior is not what I want. Other related (but to my mind, not completely helpful in this regard) questions: Setting scroll bar on a jscrollpane Making a JScrollPane automatically scroll all the way down. Any help in this regard would be very much appreciated.

  • Internet Explorer 8 Standards Mode Results In Broken Blank Page

    - by Agent_9191
    I'm running into a weird issue that I'm struggling to figure out what's causing the page to break. I have an internal website that's still under development (thus no link to the page) that works great in Firefox and Internet Explorer 8 in IE 7 Standards mode. But when I force it to IE 8 Standards mode the page will only display the title text in the browser tab and an otherwise completely blank page. It seems so broken that the blank page doesn't even have a context menu. The page generally looks like this: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="IE=8" http-equiv="X-UA-Compatible" /> <title>Page Title</title> <link rel="shortcut icon" href="/Images/favicon.ico" type="image/x-icon" /> <link href="/Style/main.less" rel="stylesheet" type="text/css" /> </head> <body> ... </body> </html> You may notice the .less extension for the stylesheet. This is an ASP.NET MVC application and I'm making use of DotLess. I have the HttpHandler hooked up for it in the web.config. Of course there's some additional info on the page, but (in theory) it shouldn't be causing this issue. I've run the CSS and the HTML through the W3C validators and both have come back as completely valid. I'm trying the arduous task of removing/re-adding elements until it displays, but any insight into what could cause this would help. EDIT: it appears to be something related to the DotLess stylesheet. The resulting CSS is valid according to the W3C CSS validator. EDIT 2: Digging further, and making use of IE's Developer Tools to control the styles, it appears that IE is reading a single statement twice even though it only occurs once in the output. Here's the output of the Less file: a, abbr, acronym, address, applet, b, big, caption, center, cite, code, dd, dfn, div, dl, dt, em, fieldset, font, form, html, i, iframe, img, kbd, label, legend, li, object, pre, s, samp, small, span, strike, strong, sub, sup, tbody, td, tfoot, th, thead, tr, tt, u, var { margin: 0; padding: 0; border: 0; outline: 0; font-size: 100%; vertical-align: baseline; background: transparent; } blockquote, q { margin: 0; padding: 0; border: 0; outline: 0; font-size: 100%; vertical-align: baseline; background: transparent; quotes: none; } body { margin: 0; padding: 0; border: 0; outline: 0; font-size: 100%; vertical-align: baseline; line-height: 1; width: 100%; background: #efebde; min-width: 600px; } del { margin: 0; padding: 0; border: 0; outline: 0; font-size: 100%; vertical-align: baseline; background: transparent; text-decoration: line-through; } h1 { border: 0; outline: 0; vertical-align: baseline; background: transparent; font-size: 2em; margin: .8em 0 .2em 0; padding: 0; } h2 { border: 0; outline: 0; vertical-align: baseline; background: transparent; font-size: 1.8em; margin: .8em 0 .2em 0; padding: 0; } h3 { border: 0; outline: 0; vertical-align: baseline; background: transparent; font-size: 1.6em; margin: .8em 0 .2em 0; padding: 0; } h4 { margin: 0; padding: 0; border: 0; outline: 0; vertical-align: baseline; background: transparent; font-size: 1.4em; } h5 { margin: 0; padding: 0; border: 0; outline: 0; vertical-align: baseline; background: transparent; font-size: 1.2em; } h6 { margin: 0; padding: 0; border: 0; outline: 0; vertical-align: baseline; background: transparent; font-size: 1em; } ins { margin: 0; padding: 0; border: 0; outline: 0; font-size: 100%; vertical-align: baseline; background: transparent; text-decoration: none; } ol, ul { margin: 0; padding: 0; border: 0; outline: 0; font-size: 100%; vertical-align: baseline; background: transparent; list-style: none; } p { border: 0; outline: 0; font-size: 100%; vertical-align: baseline; background: transparent; margin: .4em 0 .8em 0; padding: 0; } table { margin: 0; padding: 0; border: 0; outline: 0; font-size: 100%; vertical-align: baseline; background: transparent; border-collapse: collapse; border-spacing: 0; } blockquote:before, blockquote:after, q:before, q:after { content: none; } :focus { outline: 0; } .bold { font-weight: bold; } .systemFont { font-family: Arial; } .labelled { font-style: italic; } .groovedBorder { border-color: #adaa9c; border-style: groove; border-width: medium; } #header, #footer { clear: both; float: left; width: 100%; } #header p, #header h1, #header h2 { padding: .4em 15px 0 15px; margin: 0; } #header ul { clear: left; float: left; width: 100%; list-style: none; margin: 10px 0 0 0; padding: 0; } #header ul li { display: inline; list-style: none; margin: 0; padding: 0; } #header ul li a { background: #eeeeee; display: block; float: left; left: 15px; line-height: 1.3em; margin: 0 0 0 1px; padding: 3px 10px; position: relative; text-align: center; text-decoration: none; } #header ul li a span { display: block; } #header ul li a:hover { background: #336699; } #header ul li a.active, #header ul li a.active:hover { background: black; font-weight: bold; } #header #logindisplay { float: right; padding-top: .5em; padding-bottom: .5em; padding-right: 1em; padding-left: 1em; } #title h1 { font-family: Arial; font-style: italic; font-size: 175%; text-align: center; margin-top: 1%; } .col1 { font-family: Arial; border-color: #adaa9c; border-style: groove; border-width: medium; min-height: 350px; float: left; overflow: hidden; position: relative; padding-top: 0; padding-bottom: 1em; padding-left: 0; padding-right: 0; } .col1 div.logo { text-align: center; } .col3 { font-family: Arial; border-color: #adaa9c; border-style: groove; border-width: medium; float: left; overflow: hidden; position: relative; } #layoutdims { clear: both; background: #eeeeee; margin: 0; padding: 6px 15px !important; text-align: right; } #company { padding-left: 10px; padding-top: 10px; margin: 0; } #company span { display: block; padding-left: 1em; } #version { padding-right: 1em; padding-top: 1em; text-align: center; } #menu li { padding: 6px; border-color: #adaa9c; border-style: groove; border-width: medium; min-width: 108px; } #menu li a.ciApp { text-decoration: none; font-size: 112.5%; font-weight: bold; font-family: Arial; color: black; } #menu li a.ciApp span { vertical-align: top; } .welcomemessage { font-size: 60.95%; } .newFeatures { overflow-y: scroll; max-height: 300px; } #newsfeed div .newsLabel { color: red; font-size: 60.95%; font-style: italic; } /************************************************************************************** This statement appears twice in Developer Tools.

I don't know what's causing that as it's only appearing once in the output stream. Here's an image of it too: EDIT 3: It appears that even though it duplicates that particular selector, if I change the font-size to a whole number like 61% instead of the current 60.95% (that specific to defaultly match the existing desktop app as closely as possible) it works fine. So something specific to IE duplicating that selector block and the font-size being a percentage specific to two decimal places appears to kill IE8 Standards mode completely.

  • Type '_Default' already contains a definition

    - by salvationishere
    I am developing a C# VS 2008 / SQL Server 2008 website. I have a Gridview. I included the Default.aspx and aspx.cs files below.

  • MVVM- How can I bind to a property, which is not a DependancyProperty?

    - by highone
    I have found this question http://stackoverflow.com/questions/2245928/mvvm-and-the-textboxs-selectedtext-property. However, I am having trouble getting the solution given to work. This is my non-working code: View: SelectedText and Text are just string properties from my ViewModel. <TextBox Text="{Binding Path=Text, UpdateSourceTrigger=PropertyChanged}" Height="155" HorizontalAlignment="Left" Margin="68,31,0,0" Name="textBox1" VerticalAlignment="Top" Width="264" AcceptsReturn="True" AcceptsTab="True" local:TextBoxHelper.SelectedText="{Binding SelectedText, UpdateSourceTrigger=PropertyChanged}" /> <TextBox Text="{Binding SelectedText, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}" Height="154" HorizontalAlignment="Left" Margin="82,287,0,0" Name="textBox2" VerticalAlignment="Top" Width="239" /> TextBoxHelper public static class TextBoxHelper { #region "Selected Text" public static string GetSelectedText(DependencyObject obj) { return (string)obj.GetValue(SelectedTextProperty); } public static void SetSelectedText(DependencyObject obj, string value) { obj.SetValue(SelectedTextProperty, value); } // Using a DependencyProperty as the backing store for SelectedText. This enables animation, styling, binding, etc... public static readonly DependencyProperty SelectedTextProperty = DependencyProperty.RegisterAttached( "SelectedText", typeof(string), typeof(TextBoxHelper), new FrameworkPropertyMetadata(null, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, SelectedTextChanged)); private static void SelectedTextChanged(DependencyObject obj, DependencyPropertyChangedEventArgs e) { TextBox tb = obj as TextBox; if (tb != null) { if (e.OldValue == null && e.NewValue != null) { tb.SelectionChanged += tb_SelectionChanged; } else if (e.OldValue != null && e.NewValue == null) { tb.SelectionChanged -= tb_SelectionChanged; } string newValue = e.NewValue as string; if (newValue != null && newValue != tb.SelectedText) { tb.SelectedText = newValue as string; } } } static void tb_SelectionChanged(object sender, RoutedEventArgs e) { TextBox tb = sender as TextBox; if (tb != null) { SetSelectedText(tb, tb.SelectedText); } } #endregion } What am I doing wrong?
