  • Wpf application variable not changing

    - by Hasan Zubairi
    In my application I need some variables on almost all the pages so I declared them in Application.xaml like <sys:String x:key="First">First</sys:String> and on one page I change the value in code like Resources["First"] = "This is First"; on the second page when I call the variable like String f = (string)this.TryFindResource("First"); MessageBox.Show(f); the out put is "First" and not "This is First". I also tried like. Application.Current.Properties["First"]

  • Using Remote Web Server to Initialize iPhone App

    - by Chris_K
    My iPhone app relies on a vendor's XML feed to provide data. But that feed is not locked down. The vendor could change the format of the XML at any time, although so far they've promised not to. Since I might want to tell my app to use a different URL for its data source, I'd like to set up a single "Command Central" Web page, on my own server, to direct the app to the correct data source. In other words, each time my app starts, in the background and unseen by the user, it would visit "http://www.myserver.com/iphoneapp_data_sources.xml" to retrieve the URL for retrieving data from my vendor. That way, if my vendor suddenly changes the exact URL or the XML feed that the app needs, I can update that Web page and ensure that all installations of the app are using the correct XML feed. Does anyone have any advice or examples showing this kind of approach? It seems as if this must be a common problem, but so far I haven't found a well-established design pattern that fits it.

  • How do I write raw binary data in Python?

    - by Chris B.
    I've got a Python program that stores and writes data to a file. The data is raw binary data, stored internally as str. I'm writing it out through a utf-8 codec. However, I get UnicodeDecodeError: 'charmap' codec can't decode byte 0x8d in position 25: character maps to <undefined> in the cp1252.py file. This looks to me like Python is trying to interpret the data using the default code page. But it doesn't have a default code page. That's why I'm using str, not unicode. I guess my questions are: How do I represent raw binary data in memory, in Python? When I'm writing raw binary data out through a codec, how do I encode/unencode it?

  • problem with 512x512 app icon in iTunes Connect

    - by Matthew
    I'm uploading my app to App Store and I created it in iTunes Connect. I just uploaded my 512x512px icon and then I opened Version Summary page to verify my information... I've got a set of icon that just have gloss effect. In Version Summary page I see my 512x512px icon with automatic gloss added. Is there a way to prevent this? My large app icon mustn't have gloss... In my info.plist I added the line "Icon already includes gloss effects" and I checked the box near it... Can anyone help me?

  • JQuery overlay - issues with opening twitter "Allow Access" box

    - by Gublooo
    Hey guys I'm using Jquery flowplayer tools overlay to open external links. External links are working fine with this piece of code shown in the link: http://www.demiseonline.com/misc/Iframeoverlay.html Now using this overlay - I wanted to open the twitter dialog which asks users to Allow access to their account. So in the code below, I replaced http://www.google.com with https://twitter.com/oauth/authenticate?oauth_token=VPVRIsnRz9IX4CAab7brert3jHiEs <div class="apple_overlay black" id="Overlay1" <iframe src ="http://www.google.com" width="100%" height="595px" frameborder="0" </iframe </div When I replace the code, as soon as I load the page, even before I click on the link to open the overlay - the page gets redirected to the twitter URL. Any idea why that happens for this URL. Thanks

  • Design Solution For Storing-Fetching Images

    - by Chaitanya
    This is a design doubt am facing, I have a collection of 1500 images which are to be displayed on an asp.net page, the images to be displayed differ from one page to another, the count of these images will increase in the time to come, a.) is it a good idea to have the images on the database, but the round trip time to fetch the images from the database might be high. b.) is it good to have all the images on a directory, and have a virtual file system over it, and the application will access the images from the directory Do we have in particular any design strategy in a traditional database for fetching images with the least round trip time, does any solution other than usage of a traditional database exists? ps: I use SQL Server to store these images.

  • Django, javascript and code ruse problem

    - by dragoon
    Hi, I have some sort of a design problem with my Django AJAX application. I have a template where I initialize js variable from django context variable like so: var test = "{{ test }}"; This variable is than used in a number of js functions that are needed for interface to work properly. So now I'm trying to reuse some content from this page in another page that loads it dynamically on some user interaction using jQuery.load(..), and I don't see any way how I can initialize that variable, so js functions don't work now. Is there any solution for this or may be I'm doing it wrong? Thanks.

  • Can't figure out the color of an svg element

    - by yass
    I have a very simple HTML page, viewable on gh-pages with the following code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <link href="style.css" media="screen" rel="stylesheet" type="text/css"> <script src='http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js'> </script> </head> <body> <div id="page"> <div id="content"> <div id="heatmap"> <svg style="margin-left: 80px; color: rgb(255, 255, 255);" width="800" height="880"> <g transform="translate(80,80)"> <rect style="color: rgb(255, 255, 255);" height="720" width="720"> </rect> </g> </svg> </div> </div> </div> </body> </html> with the following CSS: body { background-color: #FFFFFF; font-family: Arial, Helvetica, sans-serif; font-size: 14px; color: #FFFFFF; } #wrapper { margin: 0 auto; padding: 0; } #page { width: 1000px; margin: 0 auto; padding: 40px 0px 0px 0px; } #content { float: left; width: 660px; padding: 0px 0px 0px 0px; background: #FFFFFF; } I expect the rectangle, 'svg rect' to be the color #FFFFFF, or white. But it shows up as some other color. I opened it up in firebug, and it shows the computed color to be #FFFFF:

  • How can I emulate forward on 404 in jersey?

    - by koppor
    I have a picture on a given URL. The picture might need a referesh. I want to do the freshness-check at the time of the request. Therefore, I coded a jersey resource handling the request on the picture URL. It refreshes the picture on the filesystem if necessary. I do not want to re-code a caching mechansim, but rely on tomcat's implementation. Therefore, I would like to "forward" the request in the internal handler chain. I tried return new Viewable(sb.toString());, but a viewable is not a picture. What return type can I use? I could let the concrete picture reside on another URL and send a 307 (Temporary Redirect). Always sending that as answer seems odd to me. Related question: How to return a PNG image from Jersey REST service method to the browser

  • MYSQL Inserting rows that reference main rows.

    - by Andrew M
    I'm transferring my access logs into a database. I've got two tables: urlRequests id : int(10) host : varchar(100) path: varchar(300) unique index (host, path) urlAccesses id : int(10) request : int(10) <-- reference to urlRequests row ip : int(4) query : varchar(300) time : timestamp I need to insert a row into urlAccesses for every page load, but first a row in urlRequests has to exist with the requested host and path so that urlAccesses's row can reference it. I know I can do it this way: A. check if a row exists in urlRequests B. insert a row in urlRequests if it needs it C. insert a row into urlAccesses with the urlRequests's row id referenced That's three queries for every page load if the urlRequests row doesn't exist. I'm very new to MySQL, so I'm guessing that there's a way to go about this that would be faster and use less queries.

  • HTML javascript form submitted when image input button

    - by DreamU
    I have a form that contains this single input field, which is nothing more than a button to Print the current web page: <div align="center"> <input type="image" src="../Images/print.jpg" value="Print" onclick="printpage();" /></div> </div> After the printing, the page re-submits itself (to itself). Why does it do this and can I stop it? If I just change the type to "input", this code does not re-submit itself after printing: <div align="center"> <input type="input" src="../Images/print.jpg" value="Print" onclick="printpage();" /></div> </div> Unfortunately, our style conventions require me to use that button image rather than the standard input button.

  • Slow Client connection blocks Mongrel

    - by Sanjay
    I have a Apache + Haproxy + Mongrel setup for my rails application. When I hit a particular server page, mongrel takes around 100ms to process the request and I get the page in around 5 secs due to data transmission time on my slow home connection. Now I see that during these 5 secs of data transmission, mongrel does not serve any other request. I am surprised as that means mongrel is serving the response html to the client and is blocked till the client receives it. Shouldn't serving response be the job of Apache? This puts serious bottleneck in the no of requests Mongrel can serve as that would depend on the speed of the client connection. Is there any way that html generated by mongrel is served by apache/haproxy or any other web server like nginx? I wonder how the other high traffic sites are managing it?

  • Image gallery with a Lightbox in jQuery

    - by Alex
    Hi. I'd like to create a jQuery image gallery of showcased products. It will show one product image at a time, with Next/Previous arrows, and a brief name and price as overlay on the image. If users click it, it will go to the order page. It will have an icon to show a larger, modal version (Lightbox style) of the image with full description, price, and a link to a page to order it. In other words, it's an inline gallery, about 250px X 150px, with next/previous option, but also with a little icon to fire it up in a lightbox type modal window that can have links. Here's an example which doesn't have the inline gallery effect. Here's another, also missing the inline gallery. Is there such a beast as what I'm looking for? Thanks.

  • XML cdata tgas being erased when there's input in Russian

    - by Uri
    Hello, I have a very strange problem which I will be very thankful if someone would help me with. I have a form that has a textarea whose content is later transferred to a page that has a line like this (using DOM with php to change data on an XML file): $dom-getElementsByTagName("page")-item($itemNum)-getElementsByTagName("lang")-item(1)-getElementsByTagName("text")-item(0)-firstChild-data=$_POST['rus0']; The XML file in question looks like this: The strange thing happens when I upload it to the server and try to input Russian text, in which case it erases the CDATA completely and results in And, weirdly, the thing works fine on my own server emulator (I'm using MAMP with php 5, the remote server also has php 5) - in my machine inputing Russian works fine. Any ideas what's going on in this?

  • Codeigniter Template library, add_js() method

    - by Karl
    using This Template Library when i try and use the add_js() function it errors out. I add the regions $_scripts to the template header file but when i load the page it says undefined variable _scripts. any thoughts? changed <?= $_scripts ?> to <?= (isset($_scripts)) ? $_scripts : “”; ?> and obviously i lose the error but the js file still isnt loading. I did an echo at each step though the add_js() method and the output is correct. I also did an output of $this-js and they both had the corret output. So it gets through the get_js method fine and sets the class variable fine but i dont get anything added to the actual page.

  • How to reduce the number of cert validation requests... (IE is killing me slowly)

    - by scooterhanson
    On a customer's internal network, I can make a request to my SSL site using IE6 SP1 (on Win2K) and see one cert validation requests, but if I use IE6 SP2 (on XP) 13 separate cert validation requests get fired off. Needless to say, this slows down my page load a lot. Firefox loads the page just fine with no unnecessary cert validation requests. The server is Apache running a pretty new lampp stack. All the server certificate / CA chain configurations seem to be fine (users can authenticate w/ trusted certs, the system can communicate to other systems with that server cert, etc.) Is there anything I can do from a configuration standpoint? Any other ideas at all?

  • Using Selenium to Determining The Visibility of Elements for Print media

    - by Tom Howard
    I would like to determine if particular elements on a page are visible when printed as controlled by CSS @media rules. Is there a way to do this with Selenium? I know there is the isDisplayed method, which takes the CSS into account, but there is nothing I can find to tell Selenium which media type to apply. Is there a way to do this? Or is there another way to test web pages to make sure the elements you want are printed (and those you don't aren't)? Update: For clarity, there are no plans to have a javascript print button. The users will print using the normal print functionality of the browser (Chrome, FF and IE). @media css rules will be used to control what is shown and hidden. I would like Selenium to pretend it is a printer instead of a screen, so I can test if certain elements will be visible in what would be the printed version of the page.

  • Jquery disable link for 5 seconds

    - by John
    I have this code: $('#page-refresh').click( function() { $.ajax({ url: "/page1.php", cache: false, dataType: "html", success: function(data) { $('#pagelist').html(data); } }); return false; }); In this code is it possible that on the ajax success function it disables the #page-refresh click for 5 seconds then re-enable it? Basically if a person clicks the button and this action happens I dont want them to click and run this action again for another 5 seconds. I looked at delay() to unbind the click for this then bind it again but once it unbinded it never allowed me to click the button anymore.

  • How to edit default.aspx on SharePoint site without SharePoint Designer

    - by Magnus Johansson
    On several occations, I have faced the situation that the default.aspx page on a Site doesn't work. More specifically, a reference to a WebPart and/or Control is throwing a error because the assembly is not found. Fine, you just fire up the dreaded SharePoint Designer and remove the dependency line. However, if I wanted to use this method when not having SharePoint Designer, how could this be done? EDIT: Removing the web part using the "?contents=1" web part management page didn't help in my case. The <%@Register tag was still there and had to be removed using SharePoint Designer.

  • JavaScript and PHP - A little confused on how to work them together.

    - by Doug
    So right now, I'm just using a basic form to check a password. I want it to check the password and basically remain on page.html so I can use JavaScript to alert incorrect password or something. I'm not really sure how to do that. It seems it would bring me to check.php. I'm not too sure on the whole process, any help appreciated! Thanks! Page.html <form action="check.php" method="post"> <input type="password" name="password" /> <input type="submit" value="Submit" /> </form> check.php <?php $password = $_POST['password']; if ( $password != "testing" ) { die(); } ?>

  • How can I embed the result of a rails view in another website?

    - by NotDan
    I would like to allow users to call my ruby on rails app as a service which returns a 'div' with html content in it, and embed that div into their app (which will not be a rails application). For example, assume someone has their own php website that has a header/footer template that gets rendered, and a content area of the page that they need to fill based on some html I generate in my rails app. I would like to allow them, from php, to call to my website, get the 'div' I generate, and embed that as html in their php page. What I'm trying to do is host a service on my site that returns some html content, but actually show that content as part of another site, so that the end user only sees the other site and never really knows about mine. Is this possible?

  • Drupal rendering incomplete views

    - by Paul
    I got tapped to do some quick maintenance on a recently migrated Drupal site. I'm pretty new to Drupal, so hopefully the problem is something that more experienced guys will figure out quick. Behavior is as follows. The public content works fine as far as I can tell. When I go to login, the login form renders correctly, but when I post the form w/ my credentials, I get back a blank page (not a 404; looks like a 200 to the /user URL, but all the gets rendered is empty Head and body tags). If i refresh the page, I get the content of my profile view, but none of the site chrome or CSS. Note that this is not an issue on the site it was migrated from, so it seems like something wasn't copied over correctly. The site's not public, so I can't provide a URL, sorry!

    Hi. I have some code that uses xsl and xml. The Xml control is on the design page. The xml control id is xmlApplication The xmlstring is generated and xsl has the format with all the tables and cells etc. Here is a part of thecode of a page which generates the final product which shows the xml in a certain format. xmlApplication.Document = xmlDoc; xmlApplication.Transform = transApp; xmlApplication.DataBind(); I am guessing after xmlApplication.Databind(), xmlApplication will be converted into something that can be put inside . Is it possible to grab as a string? Please let me know if I have a wrong idea abut this. Thanks a lot.
