  • Managing multiple WCF endpoints for the same service

    - by Jacob
    I am building an single application that uses WCF to call out to multiple external endpoints. All of the remote endpoints are identical except for the URI. I would like to treat them as a pool: add and remove endpoints through configuration and have the application understand what to do. My original plan was to define one endoint in the app.config, then iterate over my list of endpoints and update client.Endpoint.Address on the fly to point to the right place. Unfortunately, that property is read-only, rendering that plan unworkable. I'm a little bit stumped here. Any suggestions on how I might accomplish this?

  • Client side javascript, creation of several elements and show each asap

    - by Sirius Lampochkin
    Client side javascript code create some elements (about 50-100) in cycle: for (var i = 0; i < list.Length; i++) { var obj = document.createElement("DIV"); obj.innerHTML = "<span class=\"itemId\">" + list[i].Id + "</span><!-- some more simple code --> "; mainObj.appendChild(obj); } There is some problem with browser rendering, for example IE just freeze until he finished the cycle and then shows all elements in one time. Is there a way to show each created element separately and immediately after "appendChild()"?

  • Resize an asp.net panel width based on a checkboxlist?

    - by larryq
    Hi everyone, I have an asp.net panel that contains a checkboxlist. I'd like to resize it so that its width fits the list's contents snugly. Right now I'm handling the panel's pre rendering event, setting its width to match that of the checkboxlist. However it appears the checkboxlist's width property reads zero (at least in this pre render method) so the panel's width is set identically, which leads to inconsistent renderings in Firefox vs IE. Does anyone have a better approach to doing what I'm attempting here? Many thanks.

  • overridden styles for flex module

    - by Anand
    Can a flex module have styles different from the main application which loads the modules? Meaning... can I have a main set of styles for the application, and separate styles for each module.. with each of them rendering their own styles without disturbing the other at runtime? My specific case: The main application is developed by me... and the modules are developed by different people who want to contribute to the main application. I want to provide some way for each of the module developers to have their own styles for their modules, without touching the main application or its styles.

  • C++ HTML template framework, templatizing library, HTML generator library

    - by Marcin Gil
    I am looking for template/generator libraries for C++ that are similar to eg. Ruby's Erb, Haml, PHP's Smarty, etc. It would be great if I it would sport some basic features like loops, if/else, int conversion to strings, etc. Parameter passing to template rendering engine is also important if I could pass all of them in a hash map instead of calling some function for each of parameters. Do you have any recommendations? I can see also the possibility of embedding languages like Lua, however I haven't found a templatizing library for that either. Thanks!

  • Red Hat cluster: Failure of one of two services sharing the same virtual IP tears down IP

    - by js.
    I'm creating a 2+1 failover cluster under Red Hat 5.5 with 4 services of which 2 have to run on the same node, sharing the same virtual IP address. One of the services on each node needs a (SAN) disk, the other doesn't. I'm using HA-LVM. When I shut down (via ifdown) the two interfaces connected to the SAN to simulate SAN failure, the service needing the disk is disabled, the other keeps running, as expected. Surprisingly (and unfortunately), the virtual IP address shared by the two services on the same machine is also removed, rendering the still-running service useless. How can I configure the cluster to keep the IP address up?

  • How to draw a sliced image in Cairo?

    - by Maz
    I am currently using the following code to draw sliced images: static void DrawImage(cairo_t *ctx,int x,int y,int w,int h,cairo_surface_t *img){ cairo_set_source_surface(ctx, img, 0, 0); cairo_rectangle(ctx, x, y, w, h); cairo_clip(ctx); cairo_paint(ctx); cairo_reset_clip(ctx); } void DrawThreeSliceImage(cairo_t* ctx,Point p,int width,cairo_surface_t *a,cairo_surface_t *b,cairo_surface_t *c){ DrawImage(ctx, p.x, p.y, cairo_image_surface_get_width(a), cairo_image_surface_get_height(a),a); DrawImage(ctx, p.x+cairo_image_surface_get_width(a), p.y, width-(cairo_image_surface_get_width(a)+cairo_image_surface_get_width(c)), cairo_image_surface_get_height(b),b); DrawImage(ctx, p.x+(width-cairo_image_surface_get_width(c)), p.y, cairo_image_surface_get_width(c), cairo_image_surface_get_height(c),c); } However, there is no output. I have tried rendering to both xlib and png surfaces, neither seems to work, that is nothing is drawn. Also, I have written the input surfaces to png files, and they appear to be working. Thanks.

  • Silent Printing of PDF From Within Java

    - by Paul Reiners
    We are looking into silent printing of PDF documents from within Java. The printing will be invoked from the desktop and not through a browser so we cannot use JavaScript. PDF Renderer is an operational solution but their rendering quality is not acceptable. iText does not seem to be pluggable with the Java print service. There are some commercial Java libraries, jPDFPrint by Qoppa, JPedal, and ICEpdf which we have not tried out yet. Does anybody have any experience with PDF silent printing from Java?

  • Is there a decent vector / spline library for php?

    - by Brendan Heywood
    Does anyone know of the best way to render clean vectors into a php image and then serve it as a jpeg/png? Specifically I want to draw lines, polygons and splines which are anti-aliased and then serve them up as jpegs. Preferably also with an alpha option when rendering. What would be spectacular is a php library with a similar API to Raphael (without the animation) - not only because Raphael has a great API but also because I'm already using it on my website for the dynamic bits but also need to bake jpeg's in parallel for static consumption.

  • Flex datagrid - determining when grid has completed renderering?

    - by ccdugga
    hi, i have a datagrid which contains a number of itemrenderers, it is populated each time a user does a search. Is there an event which can tell me when the datagrid has completed rendering all new rows and item renderers? I need to trigger an event once everything has been created so that i can resize then container which holds the grid. Currently im using DataGridEvent.HEADER_RELEASE and CollectionEvent.COLLECTION_CHANGE events to manage this however the problem with these events is that they get called as each new row is being added to the datagrid. therefore the whole process is becoming sluggish. Does anyone have any suggestions?

  • FOP Encoding issue

    - by Ravi chandra
    Hi Guys, I have a similar issue.. I have HTML stored in DB clob. I am retrieving that and converting to XHTML using TIDY.jar. Once i got XHTML then using FOP i am converting to XSL-FO. Finally XSL-FO is rendering in PDF. Previously everything is working fine with Linux-WAS5-java1.4. Recently we migrated the apps to Linux-WAS6-Java1.5. Now XHTML to XSL-FO is messing up everything. XSL-FO contains ???(Question marks) in the place of Euro, spase(nbsp), Agrave, egrave ..etc. I tried changing the JVM encoding to UTF-8 and also i have modified my servlet request and response to support UTF-8. I am helfless and unable to figure where exactly the issue is coming out. Can someone please check this and suggest me some solution. Thanks in advance

  • What tech stack/platform to use for a project?

    - by danny z
    Hey guys, This is a bit of a weird meta-programming question, but I've realized that my new project doesn't need a full MVC framework, and being a rails guy, I'm not sure what to use now. To give you a gist of the necessary functionality; this website will display static pages, but users will be able to log in and 'edit their current plans'. All purchasing and credit card editing is being handled by a recurring payment subscriber, I just need a page to edit their current plan. All of that will be done through (dynamic) XML API calls, so no database is necessary. Should I stick with my typical rails/nginx stack, or is there something I could use that would lighten the load, since I don't need the Rails heft. I'm familiar with python and PHP but would prefer not to go that route. Is Sinatra a good choice here? tl;dr: What's a good way to quickly serve mostly static pages, preferably in Ruby, with some pages requiring dynamic XML rendering?

  • How to achieve the recessed text style as in Apple's Messages for Mac?

    - by Thruth
    I'd like to replicate the recessed text style of Messages/iMessage, or, the text "white-shadow" style on a light gray background. Please refer to an image here for the style I desire. As you can see, the texts are with "white-shadow" even on the light gray background. The bold texts do have subpixel rendering while the gray texts don't (by design?). I've tried setBackgroundStyle:NSBackgroundStyleRaised . However it was generating shadows darker than the background. setBackgroundStyle:NSBackgroundStyleLowered was worse that it even overrode my font colour setting. So, what is the right way to do this? Any tricks or just have to subclass NSTextFields ? Thanks.

  • What's the best way to convert a .eps (CMYK) to a .jpg (RGB) with Image Magick

    - by Slinky
    Hi All, I have a bunch of .eps files (CMYK) that I need to convert to .jpg (RGB) files. The following command sometimes gives me under or over saturated .jpg images, when compared to the source EPS file: $cmd = "convert -density 300 -quality 100% -colorspace RGB ".$epsURL." -flatten -strip ".$convertedURL; Is there a smarter way to do this such that the converted image will have the same qualities as the source EPS file?

  • iframe for ad loading good or bad?

    According to Yahoo's "Best Practices for Speeding Up your Site", the pros for using iframes: Helps with slow third-party content like badges and ads Download scripts in parallel but the cons are: Costly even if blank Blocks page onload I want to use an iframe to load ads using the technique mentioned on this site: http://meanderingpassage.com/2007/08/15/keeping-javascript-widgets-from-controlling-your-blog/ Does using this technique mean that as soon as the html contents requested by the iframe are returned to the client, it will load the ad script, potentially blocking the rest of the page's rendering and downloading? Or will the iframe request get processed concurrently while rest of the document is downloaded and rendered?

  • Django admin output extra HTML in ModelSite

    - by VoteyDisciple
    Ultimately, I want to add an <iframe> to the display of a particular model on Django's admin page. Django is already rendering the form for this model correctly, but I want to add this <iframe> in addition to Django's form. The src attribute needs to involve the primary key for the currently-displayed record. I've learned how to properly override the change_form.html template through Django's documentation, and I can add markup to the right block, but I can't figure out how to access the primary key value. (No amount of determined Googling has helped at all.) Alternatively, is there a direct way to specify that I want to produce extra output in my ModelSite definition?

  • Attributed strings in UITableViewCells without WebView?

    - by arnekolja
    Hello, does anyone know if there's a way in with 3.0+ to display attributed strings within a UITableViewCell without using a UIWebView for that? I need to display a string with linked, tappable substrings as the typical detailTextLabel. I wouldn't mind exchanging this UILabel against another type of view, but I think a UIWebView could be just too slow when rendering a table with hundrets of cells. Or does someone have opposite experiences here? So my question is: what's the best way to achieve mixed strings in a very large table without a great performance hit? I searched for this almost a whole day now, but I can only find old posts mentioning that there's no attributed string on the iPhone (outdated, as this was pre-3.0) and/or saying that they use a UIWebView for that. But really, I don't think this would perform very well on large tables, would it? Many, many thanks in advance Arne

  • Loading textures in an Android OpenGL ES App.

    - by Omega
    I was wondering if anyone could advise on a good pattern for loading textures in an Android Java & OpenGL ES app. My first concern is determining how many texture names to allocate and how I can efficiently go about doing this prior to rendering my vertices. My second concern is in loading the textures, I have to infer the texture to be loaded based on my game data. This means I'll be playing around with strings, which I understand is something I really shouldn't be doing in my GL thread. Overall I understand what's happening when loading textures, I just want to get the best lifecycle out of it. Are there any other things I should be considering?

  • OpenGL: Textured Primitives + High Framerate

    - by James D
    Short version: What's the best practice going forward for efficiently rendering large numbers of independent texture-mapped, lighted 2D/3D primitives (circles, rects, etc.) in OpenGL? For example: a typical particle system using billboarded quads/triangles, point sprites, or whatever other technique, with blending. Because after reading this thread on the messiness of OpenGL versioning/deprecation I'm starting to have my doubts. My specific question is not the ABCs of displaying primitives in OpenGL, but rather how to do so efficiently in post-deprecation (or pre-deprecation) OpenGL, in a way that's going to be compatible with a wide range of commodity hardware and in a way that's not going to break or itself get deprecated, five years down the line. Thanks!

  • ASP.NET - Themes and Relative Referencing

    - by user70192
    Hello, I have an ASP.NET application that uses themes. Let's pretend I have a theme named "MySkin". I have a page that is in a sub-directory of my application. When I reference a page that uses "MySkin", I noticed that ASP.NET renders a link element that walks up to the root of the site and then down into the App_Themes directory. Here is an example link element I found in a rendered ASP.NET page: <link href="../../App_Themes/MySkin/theme.css" type="text/css" rel="stylesheet" /> Is there a reason that the rendered link element does not use the following instead: <link href="/App_Themes/MySkin/theme.css" type="text/css" rel="stylesheet" /> Is this a browser compatibility issue or is there another reason? The reason I am asking is because I am rendering my ASP.NET page using Server.Execute and storing the result in a different directory. Because of this, I would prefer to use the second way to reference my theme's css. Thank you!

  • WPF: Turning off animations, data binding temporarly for invisible objects?;)

    - by TomTom
    I have a window that contains a tab control - basically multiple sheets with visualizations on them. The visualtizations are: possible very resource intensive during rendering relying on constant data updates to update their underlying models Obviously only one sheet can be visible every time ;) Anyone knows of a good way to turn off all visualization, animations, data binding for a control / panel and it's contained controls? If I would find a way to do that, I could simply turn off all the invisible sheets and reactivate them as needed. The models must be kept running - some of the visual stuff is pretty complex and really relies on constant data updates, and recalculating it when someone switches tabs would be too hard.

  • IHTMLTxtRange.execCommand("Copy",false,null) fails due to IE settings

    - by srirambalaji-s
    We have a .Net application that is used for editing/rendering customized HTML documents. It is hosted in IE using the AxSHDocVw.AxWebBrowser controls. We proceed with navigating to "about:blank" page initially then we change the Document by writing our custom values into it. The problem we are facing is the call to IHTMLTxtRange.execCommand("Copy",false,null) is failing if we don't enable the IE Security Settings in the Internet Security zone (Scripting-Allow Programmatic Access to Clipboard ). In order to bypass the security setting ,I tried to point to a local html file initially while navigating. But this fails as soon as I modify the Document. I want to use the IHTMLTxtRange.execCommand("Copy",false,null) command so that I can customize our Copy/Paste operations. Is there any other way I can do this. Please share your ideas inorder to overcome this situation. Thanks. Sriram

  • Workaround for Outlook 2007 for wrapping text around image with margin?

    - by DavidW
    As we all know, Outlook 2007 uses the Word 2007 rendering engine, causing endless grief when designing HTML email message. [Insert rant here] In particular, float, margin, and padding are - shall we say? - poorly supported. To simulate float so that text wraps around an image, apparently we can simply use: <img src="foo.png" align="right"> The issue is padding/margin. Without padding/margin, the wrapped text butts up against the image which looks goofy. One workaround is to edit the image and add transparent framing that simulates margin. Does anyone know any other workarounds?

  • Font-face, Raphael and IE8

    - by Sucrenoir
    I am desesperatly trying to get some google font faces to work with Raphael (SVG / VML rendering JavaScript library) on IE8. At first i tried the google fonts code. My second try has been to download and convert the fonts to host my own more complete css. Now the fonts show in the html part of the page (inside a modified bootstrap nav dropdown), but it does not work in the VML canvas (generated by Raphael). Example here : http://beta.yetiprint.com/fr/etiquettes-autocollantes/4-etiquettes-couleur-ronde.html Is it possible to get that working in iE8? Any clue?
