  • The query parameter '$format' begins with a system-reserved '$' character but is not recognized

    Tuesday morning I was ranting on Twitter , well really whining, about how WCF Data Services does not support JSON format out of the box. Fortunately I was shown the answer in replies to my rant. So I want to share this with you. First, I made the mistake...(read more)...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Unable to use certain Fonts programatically in ASP.Net

    - by TooFat
    I am trying to programatically create a bitmap with a specified font in ASP.Net. The idea is that the text, font name, size color etc. will be passed in from variables and a bitmap of the text using the font etc will be returned. However, I have been finding that I am only able to do so using the following code with certain fonts. <div> <% string fontName = "Segoe Script"; //Change Font here System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(100, 100); System.Drawing.Graphics graph = System.Drawing.Graphics.FromImage(bmp); System.Drawing.Font fnt = new System.Drawing.Font(fontName, 20); System.Drawing.SolidBrush brush = new System.Drawing.SolidBrush(System.Drawing.Color.Red); graph.DrawString("Help", fnt, brush, new System.Drawing.Point(10, 10)); bmp.Save(@"C:\Development\Path\image1.bmp"); this.Image1.ImageUrl = "http://mysite/Images/image1.bmp"; %> <asp:Label ID="Label1" runat="server" Text="Label" Font-Names="Segoe Script"> <%Response.Write("Help"); %></asp:Label> //Change font here <asp:Image ID="Image1" runat="server" /> </div> If I change the font name in the areas indicated by the comments to Arial or Verdana both the image and the label appear with the correct font. If however, I change the font name in both locations to something "Segoe Script" the Label will show up in Segoe Script but the image is in what looks like Arial.

  • How to re-enable tray icons for applications in ubuntu 13.10?

    - by andraaska
    Unfortunately in new Ubuntu 13.10 there is no Tray Icon and Whiteliting is removed. The older solutions are not works for me, e.g.: No such schema 'com.canonical.Unity.Panel' message answered when I try to use the gsettings set com.canonical.Unity.Panel systray-whitelist "['all']" comand. How can I get tray icons back (for applications that put icon in tray like Truecrypt, Pidgin, Aqualung, gnome-system-monitor, gyache, and so many more...) in Unity ? The most annoying is that the user loses control over applications can not detect itself that it has no tray icon... (e.g.: gnome-system-monitor, truecrypt...) At least Aqalung send a message about unable to put icon on systray! Thanks

  • Very frequent system problems since 12.10 upgrade

    - by Jazz
    Since I recently upgrade my 12.04 install to 12.10, there is loads more instability generally. I have captured just the latest example - often occurring just after startup and login. Other random times, similar things happen - not always the same executable is reported - might be many different problems. Is everyone finding 12.10 a bit unstable (in which case I can hope for fixes to filter through over the coming months)?

  • Writing a dynamic achievement system without hardcoding rules into the application

    - by imaginative
    I really enjoyed the solution provided here for groundwork on writing an achievement framework. The problem I have is I have game designers that would like to be able to insert achievements into a CMS at runtime. In a way, it sounds insane and complex to do this, but is it really? I think the concept of having to do a hard push of the application for every new achievement is cumbersome. I would love to be able to give our designers the capability to put together new achievements by entering them into a database. It shouldn't matter what tool I'm using, but for those interested, my backend is being written in JRuby (Ruby on top of the JVM). What are some possible ways of going about abstracting the logic in the aforementioned link even further so that rules can be interpreted at runtime?

  • Facebook Registration Plugin redirects in wrong situation

    - by AVProgrammer
    I am using the PHP Facebook SDK to leverage the Facebook registration/login plugin. I am referring to: http://www.masteringapi.com/tutorials/how-to-use-facebook-registration-plugin-as-your-registration-system/15/ Currently, the browser redirects away from the registration page, no matter if I am signed in to Facebook or not. <div id="fb-root"></div> <script> window.fbAsyncInit = function() { FB.init({ appId: '<?php echo $facebook->getAppID() ?>', cookie: true, xfbml: true, oauth: true }); FB.Event.subscribe('auth.login', function(response) { window.location.reload(); }); FB.Event.subscribe('auth.logout', function(response) { window.location.reload(); }); <?php if($_SERVER['PHP_SELF'] == '/register/index.php'){?> FB.getLoginStatus(function(response) { if (response.status == "connected" || response.status == "unknown") { window.location = "http://<?=SITE_HOST?>/"; } }); <?php }?> }; (function() { var e = document.createElement('script'); e.async = true; e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js'; document.getElementById('fb-root').appendChild(e); }()); The part that is causing this unwanted redirect is this: <?php if($_SERVER['PHP_SELF'] == '/register/index.php'){?> FB.getLoginStatus(function(response) { if (response.status == "connected" || response.status == "unknown") { window.location = "http://<?=SITE_HOST?>/"; } }); <?php }?> This function is supposed to redirect a "connected"1 user, away from the registration page. Unfortunately, even when I access this page from a brand-new browser (Firefox, just installed, which means no cookies or sessions exist) and I am still redirected. Note the PHP code below[2]. Also, the SITE_HOST is a constant for the www. address. I think the actual condition that is being met is response.status being equal to "unknown". This status check implies an unsuccessful response from Facebook, right? Without this getLoginStatus check in the code, it will actually load the the registration page, and a Facebook registration form: Note how it says: "You have registered", which I did a month ago (assuming this qualification is met by allowing the Facebook App permissions, which was done when I initially installed the Facebook SDK). So why would the redirect code work for me (seemingly), then still redirect me when I am using a browser NOT signed in to Facebook? Also, the jQuery function at the bottom of the script loads all.js. This is all I need, right? Footnotes: Someone with "connected" status is logged in to Facebook and has approved your Facebook App permissions. No matter which page this was on it caused this, and since this code appears in a global include file, I've restricting from printing to only on the registration page, which was the intention for this code to my understanding.

  • The ETL from Hell - Diagnosing Batch System Performance Issues

    Too often, the batch systems that underlie a lot of database processing just grow without conscious design. When runs start to extend beyond their allotted time, and tuning no longer solves the problem, it is often discovered that batches are run in series, with draconian error handling. It is time to impose some rational design, and Nigel is a seasoned healer of batch processes.

  • Five years old Ubuntu system - dist-upgrades always went fine, however some tasks remain

    - by knb
    I have a PC with a current Ubuntu distribution installed. I've upgraded many times since 5.10. It always went well, however some tools or features were kind of left behind in a unsatisfactory state: grub to grub2 - is it an really necessary to switch the boot loader some time to grub2. Upgrading this scares me abit. I still have ext3 devices - is it worth upgrading to ext4? should I wait for btrfs? hibernation and suspend- it only worked in 5.10, since 6.04 it was messed up. Should I really care? Any chance to repair this myself? Simply by cleanup or hacking config files. It is a desktop PC after all. So energy saving functionality is not really needed. I am using vmware workstation 6.5 and the latest kernel that supports it is 2.6.32. This is my default kernel now, ignoring 2.6.35. Am I missing anything important in the new kernel now?

  • System hangs at glReadPixel call with GL_TEXTURE_2D_ARRAY for texturing

    - by Roshan
    I am calling glReadPixel after glDrawArray call. I am rendering a geometry with 3D texture on it as a target GL_TEXTURE_2D_ARRAY. My systems hangs at glreadpixel call. When i use target as GL_TEXTURE_3D the issue does not occurs and it correctly reads the framebuffer contents. glReadPixels(0, 0, GetViewportWidth(), GetViewportHeight(), GL_RGBA, GL_UNSIGNED_BYTE, (GLvoid *)rendered_pixels); I am using SNORM textures with GL_byte data in glTeximage3D call and I am not calling glPixelStorei, is it because of this? What should be the parameter for pixelstore call?

  • How to test reliability of my own (small) embedded operating system ?

    - by TridenT
    I've written a small operating system for embedded project running on small to medium target. I added some automated unit test with a high test code coverage (95%), but the scope is only the static part. I got some code metrics as complexity and readability. I'm testing my code with a rule checker with MiSRA support, and of course fixed all warnings. I'm testing the code with a static analyzer and again fixed all warnings. What can I do now to test - and improve - the reliability of my OS ? How about the dynamic part ?

  • System checks for disk drive error every time it boots

    - by Starx
    When my disk space for the ubuntu installation partition was getting low, from a live cd, I used gparted to increase its volume capacity, but deleting another partition and merging it to the ubuntu partition.

  • Aide On a Low Memory System

    - by Jason Mock
    I have a Linux server running on a Linode.com VPS, where I'm trying to utilize aide to detect any issues. However, the nightly aide run uses up all of my available memory and swap (512MB RAM / 384MB SWAP). I've tried adding a script to /etc/cron.daily that would stop/start services using a lot of memory (apache2, mysql) during the aide run. Unfortunately, it seems like aide continued to use every available byte (including the space freed up from apache2 and mysql). Here's a graph from munin showing what happens when aide runs: Note the spike of memory usage, well into swap, when aide runs Any suggestions on tuning aide to not use so much memory, or is there an alternative to aide that doesn't behave this way?

  • Fusion-Icon does not show up in system tray

    - by Schubibuntu
    I can't find a solution for my problem online: I'm running Unity 2D in Ubuntu 11.10 and want to enable compiz effects. I installed compiz config settings manager, and Fusion-Icon, but when I start Fusion-Icon nothing happens. When I execute it from terminal it stucks at lines like "setting update 'command'" or "setting update 'next_key'" I already set the whitelist for the panel to 'all'. Anyone knows what I'm missing? Thanks in advance!

  • How much trust can I put behind a computer system? How can I measure trust?

    - by danmine
    How much trust can I put in a standard computer running windows? To what certainty can I be sure it will run my code the way I wrote it? How can I be sure that if I declare something like "int j = 5;", j will alway be 5? Is there a way to measure trust in a standard x86 computer system? What kind of protections are there to make sure that j = 5? I'm thinking about critical systems where nothing can be off even by one bit and everything must run exactly the way it was written to run.

  • System beeps on shutdown

    - by Nicholas Smith
    Very recently a couple of our systems have started making beeps on shutdown, we've not been able to isolate the exact time that they've been updated and it's occuring, but I've narrowed it down to being not pcspkr or snd_pcsp as both are blacklisted under modprobe, and rmmod'ed just to be sure. Now I'm a bit puzzled as I was under the impression those were the only two modules that could make the beep, is there a third lurking that I need to blacklist? Edit: I've copied the results of lsmod over on Pastebin.

  • Implementation of recurring fee system

    - by TPSstar
    I'm developing an application which will list members who have not paid their any previous month's fee and a separate list for those who have paid the fee. So, lets say a member who will be paying fee through out the year, each month and if he didn't pay fee for march 2013 then app should highlight him as un-paid member. What would be best practice to achieve it. Adding fee invoices for whole year already in database when member is added then loop through his payments to check if fee is paid or not, or add a validation date for member on his each payment, for example payment made in Feb 2013 then member is valid till 28.02.2013. Check if date today is 28.02.2013 then he has not paid..

  • z-index not working in IE8 with the sortable jQuery plugin

    - by Ojtwist
    I'm working with the jQuery Sortable plugin to drag and drop images from one box to another box. This works fine in ff,chrome and safari but it fails in IE8. It seems that when you start dragging that the image is send to the back. I've tried to solve this by adding the z-index option to the sortable plugin, i've tried appending it to a node higher in the hierarchy (body). It appears that setting a z-index on every other item in the page would fix this, haven't tried it yet and i'm not planning on doing this because this would mess up alot. So the user can drag an image from 1 gallery to the next gallery screenshot of how it should work: http://img69.imageshack.us/i/draganddrop.jpg/ Some html: <!--SECOND ARROCRDION ITEM --> <a class="flickr_accordeon_header" id="flickr_second_header" href="javascript:;">__MSG__SEARCH_FOR_PHOTOS__</a> <div> <p class ="flickr_text" > __MSG__SEARCH_FOR_PHOTOS__</p> <form method="GET" action="javascript:;"> <p> <input type="text" value="__MSG__SEARCH__" id="flickr_key_input" class="flickr_changeColorNormal" /> <button class="s3d-button flickr_search" id="flickr_seach_button"> <span class="s3d-button-inner" >__MSG__SEARCH__</span> </button> <img src="/devwidgets/flickr/images/ajax-loader-gray.gif" alt="__MSG__LOADING_IMAGE__" id="flickr_loading_img" /> <a href="javascript:;" id="flickr_refresh_key_button"><img src="/dev/_images/recent_activity_icon.png" alt="refresh" title='refresh' /></a> </p> </form> <div id="flickr_input_error">__MSG__INPUT_ERROR__</div> <div id="flickr_input_same_error">__MSG__INPUT_SAME_ERROR__</div> **<div id="flickr_key_gallery" ><ul class="flickr_key_ul"><li></li></ul></div>** <div id="flickr_key_pagging" ></div> </div> </div> <!--SLIDING SIDEBAR --> <div id="flickr_sidebar" class="jcarousel-skin-tango"> <div id="flickr_side_paging"></div> **<ul> <li><img src="/devwidgets/flickr/images/drop-image.png" alt="__MSG__DROP_HERE__" class="flick_drop_here"></li> </ul>** </div> The images get rendered into the ul, so basically it's just an ul with li's with images javascript for sortable: horizontal: { helper: "clone", // Instead of dragging the real image a copy will be dragged connectWith: ["#flickr_sidebar ul"], // To be able to drag and drop an image to another image gallery they need to be connected cursor: 'pointer', //change the cursor when dragging opacity: 0.50, //Change the opacity while dragging appendTo: 'body', //When dropped the images need to be appended to the image gallery where they are dropped containment: 'body', //Make sure the user can't drag the images outside the widget revert: true, // if the user releases the image ouside the dropbox it'll return to it's original position zIndex: 9999 } I've tried it with setting the dragged image to absolute and the container on relative... doesn't work Anyone know how to solve this in IE8 ?
