• Visualforce dataTable: is there a way to stop it from rendering cellpadding attribute?

  - by codeulike

  In Visualforce, I'm using an <apex:dataTable> component as follows: <apex:dataTable value="{!Qualifications}" var="qual" styleClass="cv_table" > <!-- etc... --> ... and then I'm using CSS to style the table, via the class name. Trouble is, VisualForce renders HTML like this: <table class="cv_table" id="j_id0:j_id26" border="0" cellpadding="0" cellspacing="0"> <!-- etc... --> The class attribute is there as I wanted, but there's also cellpadding and cellspacing specified, that interfere with my CSS. Is there a way to stop Visualforce from rendering the cellpadding and cellspacing attributes for an <apex:dataTable>?

• Text rendering still blurry : Best font for WPF application?

  - by Holli

  I know this is a very subjective question but as text rendering in WPF is still an issue I have to make the best out of it. In WPF Application text tend to become blurry that is no secret. Also there are countless website about this topic and how you get around this problem. But I wonder ... text blurriness seems to affect some fonts more that others. So I am still looking for the best font available to get around this issue. So far I am still using Arial and it doesn't look good. But I am sure some other font are more suitable for the task at hand.

• how to convert a 2d path to a 3d shape in Three.js?

  - by VirtualWorld

  i need to have the 3d of this: http://jsfiddle.net/dAdKm/ but when i use this code: var shape = new THREE.Shape(); shape.moveTo(20,20); shape.bezierCurveTo(20, 100, 150, 100, 150, 20); shape.moveTo(20,20); shape.lineTo(20, 100); shape.lineTo(150, 100); shape.lineTo(150, 20); var shape3d = shape.extrude(extrudeSettings); var shapePoints = shape.createPointsGeometry(); var shapeSpacedPoints = shape.createSpacedPointsGeometry(); var material = new THREE.MeshBasicMaterial({ color: 0x0000ff }); var shapeMesh = new THREE.Mesh(shape3d, material); the result is not same as 2d context result, why? what is the problem?

• How do you calculate the reflex angle given to vectors in 3D space?

  - by Reimund

  I want to calculate the angle between two vectors a and b. Lets assume these are at the origin. This can be done with theta = arccos(a . b / |a| * |b|) However arccos gives you the angle in [0, pi], i.e. it will never give you an angle greater than 180 degrees, which is what I want. So how do you find out when the vectors have gone past the 180 degree mark? In 2D I would simply let the sign of the y-component on one of the vectors determine what quadrant the vector is in. But what is the easiest way to do it in 3D?

• Is there a nice XSL stylesheet for client-side DocBook rendering?

  - by Steven Huwig

  I want the DocBook documents in my SVN repository to look nice if someone looks at them in a web browser. I've started to write a CSS stylesheet, but I think that it will have significant limitations -- particularly ones regarding hyperlinks. There is a large body of DocBook XSL stylesheets at the DocBook site , but they don't seem to be appropriate for browser rendering. I don't want to generate static documents and put them into SVN. I want them to be basically readable for other developers without much hassle. I could write my own browser-appropriate XSL stylesheet to convert DocBook to HTML, but it seems like someone else must have already done this. I just don't know where to find it.

And I want to save the current web page state to the sever and rendering it in the server. Is there any Javascript library for this task? Thanks!

• System.Drawing - bad text rendering using DrawString on top of transparent pixels.

  - by mackenir

  When rendering text into a bitmap, I find that text looks very bad when rendered on top of an area with non-opaque alpha. The problem is progressively worse as the underlying pixels become more transparent. If I had to guess I'd say that when underlying pixels are transparent, the text renderer draws any anti-aliased 'gray' pixels as solid black. Here are some screenshots: Text drawn on top of transparent pixels: Text drawn on top of semi-transparent pixels: Text drawn on opaque pixels: Here is the code used to render the text: g.SmoothingMode = SmoothingMode.HighQuality; g.DrawString("Press the spacebar", Font, Brushes.Black, textLeft, textTop);

• How do I write a spec to verify the rendering of partials?

  - by TheDeeno

  I'm using rr and rspec. Also, I'm using the collection short hand for partial rendering. My question: How do I correctly fill out the the following spec? before(:each) do assigns[:models] = Array.new(10, stub(Model)) end it "should render the 'listing' partial for each model" do # help me write something that actually verifies this end I've tried a few examples from the rspec book, rspec docs, and rr docs. Everything I try seems to leave me with runtime errors in the test - not failed assertions. Rather than show all the transformations I've tried, I figured all I'd need if someone showed me one that actually worked. I'd be good to go from there.

• Is there a way to avoid IE7 quirks mode while rendering XML + CSS?

  - by Steven Huwig

  I've got some DocBook documentation styled with a CSS xml-stylesheet declaration. It looks great in Firefox, but IE7 doesn't seem to understand the CSS child selectors (e.g. section > title { ... }). I think this is because IE is running in quirks mode to render this XML, and older versions of IE didn't support that CSS syntax at all. The pages I found on the web all seem to focus on HTML and XHTML doctypes and how IE will behave given various permutations of these values. I couldn't find any information about straight XML + CSS. Worse yet, it seems that random XML documents always end up in quirks mode, no matter what format or stylesheet directives they have. Is XML rendering in IE doomed to be IE5.5 compatible? Will I really have to rewrite my CSS?

• How can I test if a point lies within a 3d shape with its surface defined by a point cloud?

  - by Ben

  Hi I have a collection of points which describe the surface of a shape that should be roughly spherical, and I need a method with which to determine if any other given point lies within this shape. I've previously been approximating the shape as an exact sphere, but this has proven too inaccurate and I need a more accurate method. Simplicity and speed is favourable over complete accuracy, a good approximation will suffice. I've come across techniques for converting a point cloud to a 3d mesh, but most things I have found have been very complicated, and I am looking for something as simple as possible. Any ideas? Many thanks, Ben.

• Issues rendering image in flash via Context.Response.Write C# asp.

  - by Justin

  I am having an issue rendering images in flash via a character array. I am sending it from a webhandler via Context.Response.Write as a Base64CharacterArray. It functions 100% properly in a windows environment, however when using a Mac the image data is not retrieved correctly causing the image to appear incorrectly. It does not affect the data,however as it is rendered properly in a player which accesses the data via a webservice. I am at the end of my rope on this one. Anything will help. You can find an example at the following url http://www.discoverirelandtoday.com/photoalbum/Public/Main.aspx Thanks

• Sanitize HTML before storing in the DB or before rendering? (AntiXSS library in ASP.NET)

  - by user102533

  I have an editor that lets users add HTML that is stored in the database and rendered on a web page. Since this is untrusted input, I plan to use Microsoft.Security.Application.AntiXsSS.GetSafeHtmlFragment to sanitize the HTML. Should I santiize before saving to the database or before rendering the untrusted input into the webpage? Is there an advantage in including the AntiXSS source code in my project instead of just the DLL? (Maybe I can customize the white list?) Which class file should I look in for actual implementation of the GetSafeHtmlFragment

• Level editor for 3D games with open format or API?

  - by furtelwart

  I would like to experiment with machine generated levels for a 3D game. I'm very open which game this will be. I just like the idea to run through a generated map. For this approach, it would be great if I can use an API or an open format for level designs. Is there an open source level system that can be used in several game engines (ego shooter or whatever)? I don't know if I explained my point clearly, so please add a comment with your question. I will try to clearify my point.

• How can I return JSON from node.js backend to frontend without reloading or re-rendering the page?

  - by poleapple

  I am working with node.js. I want to press a search button, make some rest api calls to another server in the backend and return the json back to the front end, and reload a div in the front end so that I won't have to refresh the page. Now I know I can reload just a div with jQuery or just Javascript dom manipulation. But how do I make it call a method on the server side? I could have a submit button and it will make a post request and I can catch it and make my api calls from there, however from the node.js side, when I return, I will have to render the page again. How do I go about returning JSON from the back end to the front end without re-rendering or refreshing my page? Thanks.

• Why is iphone Simulator not rendering HTML5 page correctly?

  - by user364978

  hello all, I have a page I am developing in .net using HTML5 intended for a WebView in an iphone App. The page looks just fine in Safari. When I load it in the iphone Simulator it is rendering as plain text, no styles or js loading. I thought it might be an issue with .net, but seeing as it works in Safari i am stumped. When I use the XHTML doctype it works just fine in the Simulator. Any ideas why this is occurring and what the fix may be? Thanks!

• What would be a good starting point for development of a 3D application for representation of struct

  - by Lela Dax

  I was thinking QT on OpenGL. Multiplatform ability and being able to be closed (at no cost) at a later point would be important points. But I'm very interested in finding a way that is not only viable but also has the least amount of reinvention of the wheel. e.g. "Why not Ogre? A ready powerful 3D engine without reinventing that part". But I'm very uncertain in what is the optimal collection of tools for that job.

• How do I load a Direct X .x 3D model in iPhone SDK?

  - by Alex

  I have been searching the internet for the last few days trying to figure this out. My goal is to draw a textured and animated .x file exported from a 3D program. I found a tutorial of how to load and draw a .obj file, which I understand, but the tutorial doesn't say how to texture it, and .obj doesn't support animation. The .x file structure is human readable just like .obj, but I have no clue how to texture it, and I might be able to figure out how to animate it, but I would prefer to be instructed on that. Any help would be GREATLY appreciated.

• How do I MVVM-ize this MouseDown code in my WPF 3D app?

  - by DanM

  In my view, I have: <UserControl x:Class ... MouseDown="UserControl_MouseDown"> <Viewport3D Name="Viewport" Grid.Column="0"> ... </Viewport3D > </UserControl> In my code-behind, I have: private void UserControl_MouseDown(object sender, MouseButtonEventArgs e) { ((MapPanelViewModel)DataContext).OnMouseDown(e, Viewport); } And in my view-model, I have: public void OnMouseDown(MouseEventArgs e, Viewport3D viewport) { var range = new LineRange(); var isValid = ViewportInfo.Point2DtoPoint3D(viewport, e.GetPosition(viewport), out range); if (!isValid) MouseCoordinates = "(no data)"; else { var point3D = range.PointFromZ(0); var point = ViewportInfo.Point3DtoPoint2D(viewport, point3D); MouseCoordinates = e.GetPosition(viewport).ToString() + "\n" + point3D + "\n" + point; } } I really don't have a good sense of how to handle mouse events with MVVM. I always just end up putting them in the code-behind and casting the DataContext as SomeViewModel, then passing the MouseEventArgs on to a handler in my view-model. That's bad enough already, but in this case, I'm actually passing in a control (a Viewport3D), which is necessary for translating coordinates between 2D and 3D. Any suggestions on how to make this more in tune with MVVM?

• UIView using Quartz rendering engine to display PDF has poor quality compared to original.

  - by Josh Kerr

  I'm using the quartz rendering engine to display a PDF file on the iphone using the 3.0 SDK. The result is a bit blurry compared to a PDF being shown in a UIWebView. How can I improve the quality in the UIView so that I don't need to rewrite my app to use the UIWebView. I'm using pretty much close to the example code that Apple provides. Here is some of my sample code: CGContextRef gc = UIGraphicsGetCurrentContext(); CGContextSaveGState(gc); CGContextTranslateCTM(gc, 0.0, rect.size.height); CGContextScaleCTM(gc, 1.0, -1.0); CGAffineTransform m = CGPDFPageGetDrawingTransform(page, kCGPDFCropBox, rect, 0, false); CGContextConcatCTM(gc, m); CGContextSetGrayFillColor(gc, 1.0, 1.0); CGContextFillRect(gc, rect); CGContextDrawPDFPage(gc, page); CGContextRestoreGState(gc); Apple's tutorial code actually results in a blurry PDF view as well. If you drop the same PDF into a UIWebView you'll see it is actually sharper. Anyone have any ideas? This one issue is holding a two year development project from launching. :(

• JSF: How to get the selected item from selectOneMenu if its rendering is dynamic?

  - by Dzmitry Zhaleznichenka

  At my view I have two menus that I want to make dependent, namely, if first menu holds values "render second menu" and "don't render second menu", I want second menu to be rendered only if user selects "render second menu" option in the first menu. After second menu renders at the same page as the first one, user has to select current item from it, fill another fields and submit the form to store values in database. Both the lists of options are static, they are obtained from the database once and stay the same. My problem is I always get null as a value of the selected item from second menu. How to get a proper value? The sample code of view that holds problematic elements is: <h:selectOneMenu id="renderSecond" value="#{Bean.renderSecondValue}" valueChangeListener="#{Bean.updateDependentMenus}" immediate="true" onchange="this.form.submit();" > <f:selectItems value="#{Bean.typesOfRendering}" /> </h:selectOneMenu><br /> <h:selectOneMenu id="iWillReturnYouZeroAnyway" value="#{Bean.currentItem}" rendered="#{Bean.rendered}" > <f:selectItems value="#{Bean.items}" /> </h:selectOneMenu><br /> <h:commandButton action="#{Bean.store}" value="#Store" /> However, if I remove "rendered" attribute from the second menu, everything works properly, except for displaying the menu for all the time that I try to prevent, so I suggest the problem is in behavior of dynamic rendering. The initial value of isRendered is false because the default item in first menu is "don't render second menu". When I change value in first menu and update isRendered with valueChangeListener, the second menu displays but it doesn't initialize currentItem while submitting. Some code from my backing bean is below: public void updateDependentMenus(ValueChangeEvent value) { String newValue = (String) value.getNewValue(); if ("render second menu" == newValue){ isRendered = true; } else { isRendered = false; } } public String store(){ System.out.println(currentItem); return "stored"; }

• Entire Table is pushed to the next page when rendering a SSRS 2005 Report (as .pdf) in SSRS 2008

  - by Pwninstein

  I have a SSRS 2005 report that I'm rendering in SSRS 2008 as a .pdf. The report contains (among other things) a table that's very simple: header row, details, no footer, no aggregation, no grouping, keep together = false, pageBreakAtStart = false, pageBreakAtEnd = false, repeatHeaderOnNewPage = true. I resized the table to be much narrower than the body of the report just to be sure it wasn't extending beyond the bounds of the report, pushing everything down. But, no matter what I try, if some of the detail rows in that table would need to be pushed to the next page, then the ENTIRE TABLE is pushed to the next page, not just the extra rows. So my question is: Is there a workaround for this problem, is this a known issue, or is it even possible to get this 2005 report to render properly in 2008? NOTE: this is related to a question that I previously asked here, and is based on this MSDN forum post started by a coworker. This question is not the same as my previous question, as I'd like to see things work properly in with a 2005 report. If it's not possible, that would be good to know, as it would indicate that we need to upgrade one of our servers to SQL 2008. Thanks!

• Using of Templated Helpers in MVC 2.0 : How can use the name of the property that I'm rendering insi

  - by Andrey Tagaew

  Hi. I'm reviewing new features of ASP.NET MVC 2.0. During the review i found really interesting using Templated Helpers. As they described it, the primary reason of using them is to provide common way of how some datatypes should be rendered. Now i want to use this way in my project for DateTime datatype My project was written for the MVC 1.0 so generating of editbox is looking like this: <%= Html.TextBox("BirthDate", Model.BirthDate, new { maxlength = 10, size = 10, @class = "BirthDate-date" })%> <script type="text/javascript"> $(document).ready(function() { $(".BirthDate-date").datepicker({ showOn: 'button', buttonImage: '<%=Url.Content("~/images/i_calendar.gif") %>', buttonImageOnly: true }); }); </script> Now i want to use Template Helper, so i want to have above code once i type next sentence: <%=Html.EditorFor(f=>f.BirthDate) %> According to the manual I create DataTime.ascx partial view inside Shared/EditorTemplates folder. I put there above code and stacked with the problem. How can i pass the name of the property that I'm rendering with template helper? As you can see from my example, i really need it, since I'm using the name of the property to specify data value and parameter name that will be send during the POST requsest. Also, I'm using it to generate class name for JS calendar building. I tried to remove my partial class for template helper and made MVC to generate its default behavior. Here what it generated for me: <input type="text" value="04/29/2010" name="LoanApplicationDays" id="LoanApplicationDays" class="text-box single-line"> As you can see, it used the name of the property for "name" and "id" attributes. This example let me to presume that Template Helper knows about the name of the property. So, there should be some way of how to use it in custom implementation. Thanks for your help!

• Is there any possibility of rendering differences betweeen firefox 3 and 3.5 and IE 7 and 8, even if

  - by metal-gear-solid

  I'm making a site for European client and he said Firefox 3 and IE 7 and 8 has more user than others browser for desktop in Europe http://gs.statcounter.com/#browser_version-eu-monthly-200812-201001-bar I've only IE 7 and Firefox 3.5.7 installed in my PC. Should I download portable Firefox 3.0 and test in it too even if I'm not using any new css property/selector which only has support in Firefox 3.5 or testing in 3.5.7 would be enough? And for IE testing in IE 7 would be enough or should i check my site in IE8 (downloading VPC image of IE8 and testing in VM) even if I'm not using any new css property/selector which only has support in IE8? Or is it necessary to use <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /> in <head> ? But what will happen when user will switch compatibility mode to IE 8 default rendering mode? Can we make site compatible in IE 7 and 8 both without using <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />? If yes, then what special we need to do.care/consider in css to make site identical in both?
