• ASP.NET MVC Get a list of users with particular profile properties

  - by Sam Huggill

  Hi, I'm using ASP.NET MVC 1 and I have added a custom Profile class using the WebProfile Builder VS add-in (found here: http://code.msdn.microsoft.com/WebProfileBuilder/Release/ProjectReleases.aspx?ReleaseId=980). On one of my forms I want a drop-down list of all users who share a specific profile value in common. I can see that I can get a list of all users using: Membership.GetAllUsers() However I cannot see how to get all users who have a specific profile value, which in my case is CellId. Am I approaching this in the right way? I have used membership roles to define which users are administrators etc, but profiles seems like the right place to group users. Any pointers both in specifics of how to access the user list but also comments on whether am I pursuing the right avenue here would be greatly appreciated. Many thanks, Sam

• How to extract hhp file from a chm file

  - by Sam

  Hi, I have an A.chm file for my windows application which runs as expected. When I decompile it using HTML workshop I get set of html files, .hhc file, .hhk file. When I compile another file B.chm from these extracted files without changing any of the files.((I want to add more html contents to this file but looks like I am losing some information after decompiling)) The output file I get is 72K where as the original file was 75K. B.chm's contents look all file when viewed in the chm viewer but the behavior is lost when when used with the application. After reading around I found that if .hhp can be extracted from a .chm file then it can be re-constructed as it is without losing any mapping or aliases. Is that true? How can I extract .hhp file from a .chm file? Thanks, Sam

• Pasting images in TinyMCE on rails app

  - by Sam Kong

  Hi, I found a weird problem with TinyMCE editor. Copying & pasting images from another domain works fine but if the images are on the same domain the path are relative but not correct sometimes. I figured out that the problem is related to the rails URL scheme. Example) Images are copied from http://mydomain.com/index.html page and the real images path is http://mydomain.com/photos/image.jpg. Editor page: http://mydomain.com/posts/new = image path is set as ../photos/image.jpg http://mydomain.com/posts/edit/123 = image path is set as ../../photos/image.jpg So I tried http://mydomain.com/posts/new/ and it worked. How do I solve this problem? Thanks. Sam

• How do I refresh TinyMCE for the code that I add with JavaScript

  - by Sam Kong

  Hi, I need to insert code for flash to TinyMCE with JavaScript. If I insert the same code using HTML menu of TinyMCE, it automatically add flash icon to the editor. But if I insert the code using JavaScript, the actual code is inserted but it shows nothing on the screen. One trick I found is toggle TinyMCE to normal textarea and back to TinyMCE. Then, it shows the flash icon. Is there a better way to do that? Thanks. Sam

• White bar at the bottom of root view!

  - by Sam

  Hi, I have two view controllers in the app. When the app starts, the layout of the root view controller's view is just fine. When a button is clicked, the view controller switches to the other one - which shows fine too. However, when the view is switched back to the root view, the contents are shifted UP by about 20 pixels, leaving a white bar at the bottom! - and it was not there when the app had started. Has anyone seen this? Any idea what's going on there? Thanks, Sam.

• loading HTML fragments with jQuery

  - by sam

  Hi everybody, I'm very new to jQuery, Ajax and things like these. I've found solutions on how to inject HTML fragments into my site: $(document).ready(function(){ $('a').click(openContent); //binding all anchors to this function }); function openContent(){ var path = $(this).attr('href'); $('#content').load(path); return false; //to prevent browser from loading the single HTML fragment } That works really fine! The problem is, these function won't be executed when clicking on anchors located in the new HTML fragment which were injected right before. So the fragment won't get injected into div, the browser will only load the fragment for itself. Hope there are solutions which aren't that tricky... thanks sam

• file upload in existing site with jquery and codeigniter

  - by Sam

  I am a new bee to ajax world. I am working on a site which uses jquery and codeigniter which processes big files like 2GB. It basically parses file and stores some extracted data from it, it uses ajax to show how far the files have been processed etc. Now I want to change the way we process files. I want to first store the file on server side and then start the processing. I evaluated upload class of codeigniter but looks like I cannot use it for this purpose as this class works with field_name and I could not find a way to make an ajax call to the upload class. My questions is : What would be suitable for my problem? Thanks in advance, Sam

• Can rails test speed be increased?

  - by Sam

  Hi all, I'm a recent convert to TDD but as my codebase grows in size and complexity, I find myself waiting longer and longer periods for the framework to load every time I want to run a test. I am aware of rspec's spec_server but I'm using Test::Unit with shoulda. I tried Snailgun (http://github.com/candlerb/snailgun) but noticed very little increased in speed. I have also tried spork-testunit (http://github.com/timcharper/spork-testunit) but it's not fully compatible with my existing tests. The delay in running tests is a definite pain point and is putting me of TDD (at least with rails). Is anyone aware of any other options? thanks Sam

• Configurability for windows application built in C#

  - by Sam

  Hi, I am working on a windows application which is developed in C#. I am kinda new in windows world. I want to restrict number of parallel threads running for this application at a given point of time. This number can be changed by user on a beefier machine. What is the best way to do this configuration and how it can be achieved. I can think of following approaches. 1. Use ConfigurationManager to read the configuration value. If user exists more than N number of threads show a message and give option there to modify the value of N. 2. Use registery entry? Thanks in Advance! Sam

• Get a random name and number (same contact) from an iPhone users address book

  - by Sam Jarman

  Hi there, I have had only very little experience using the address book in the iPhone SDK. Does anyone have a code snippet or knows the code to get a persons name and number Eg 'Fred Smith - 027 292 2112". I haven't had much luck with the stuff I've tried. I want to achieve this programmatically, and not let the user decide (random pick of the person). I also don't want to display the contact picker either any tutorial links, or anything would be appreciated. Thanks in advance Sam

• Bug in Programming Interviews Exposed?

  - by Sam

  Hi, I could not find an errata for the 2nd edition of this book. My question concerns the if-statement in the following piece of code. void removeHead (Node ** head) { Node * temp; if (!(*head)) { temp = (*head)->next; delete *head; *head = temp; } } So I understand that the point of the if-statement is to check if the Node is null. However by adding an additional "!" to the evaluation, wouldn't this negate the false value of null? Would it be correct to change it to something like: if (*head) { ... } Also if anyone knows where I can find an official errata for the 2nd edition that would be great. Thanks, Sam

• Diagnosing packet loss / high latency in Ubuntu

  - by Sam Gammon

  We have a Linux box (Ubuntu 12.04) running Nginx (1.5.2), which acts as a reverse proxy/load balancer to some Tornado and Apache hosts. The upstream servers are physically and logically close (same DC, sometimes same-rack) and show sub-millisecond latency between them: PING appserver (10.xx.xx.112) 56(84) bytes of data. 64 bytes from appserver (10.xx.xx.112): icmp_req=1 ttl=64 time=0.180 ms 64 bytes from appserver (10.xx.xx.112): icmp_req=2 ttl=64 time=0.165 ms 64 bytes from appserver (10.xx.xx.112): icmp_req=3 ttl=64 time=0.153 ms We receive a sustained load of about 500 requests per second, and are currently seeing regular packet loss / latency spikes from the Internet, even from basic pings: sam@AM-KEEN ~> ping -c 1000 loadbalancer PING 50.xx.xx.16 (50.xx.xx.16): 56 data bytes 64 bytes from loadbalancer: icmp_seq=0 ttl=56 time=11.624 ms 64 bytes from loadbalancer: icmp_seq=1 ttl=56 time=10.494 ms ... many packets later ...

• Whole Lotta Virtualization Goin' On

  - by rickramsey

  Lately we've published a lot of content about virtualization. Here's a sampling. Podcat: Technology Preview of Transcendent Memory Turns out that in a virtual environment, RAM is the bottleneck. Not because it's slow, it's not, but because each CPU still had to use its own RAM. Which gets expensive. In this podcast, Dan Magenheimer describes how Oracle and the open source community taught the guest kernel in Oracle Linux to share its memory with other CPU's. Transcendent memory will wind up saving large data centers a lot of money. Find out how. Tech Article: How to Use Oracle VM Templates This article describes how to prepare an Oracle VM environment to use Oracle VM Templates, how to obtain a template, and how to deploy the template to your Oracle VM environment. It also describes how to create a virtual machine based on that template and how you can clone the template and change the clone's configuration.

  So tonight this convo happened: Intrigued, I viewed the video Lee mentions and found that its the now infamous Brent Ozar video which shows a bug in Word on the Surface RT (you can read this article which talks about the tempest in a teacup that ensued). But Lee is correct – in the video, when Brent starts up Word 2013, we see this: That sure does look like a desktop doesn’t it! But…aren’t Windows RT devices *not* supposed to come with a desktop? Actually, it does. However, it’s not a *full* desktop. From Seth Rosenblatt’s fantastic Windows RT FAQ article: Windows RT will have a Desktop mode, but it will be restricted to pre-installed, Microsoft-produced software. This will include touch-optimized versions of Microsoft Word, Excel, PowerPoint, and OneNote as the new Microsoft Office So yes, there’s a desktop mode in Windows RT but no, you won’t be able to install apps to it. Confused yet? Read the rest of the Seth’s FAQ – it does a great job clearing the haze of confusion that Microsoft Marketing Merlins have cast upon all of us. D

• Focussing on Style Sheets and Cross Browser Compatibility.

  - by Sam

  Hello everyone, Let me begin this topic by explaining my background experience with web design. I have always been more of a back end programmer, with PHP and SQL and things. However I do have a shallow background with HTML and CSS. The problem is, I don't know it all. What I do know is, when it comes to designing (not back end dirty work) I understand basic CSS properties and I also understand HTML and I can usually throw together a sloppy web page with the two and a couple bazillion DIV tags. Anyways.. The problem I always have encountered is that when I design a website in a browser such as IE7 (and then it looks perfect on IE7), and then look at it on IE8 or IE6 or Mozilla (etc.) it gets all spacey and ugly and looks totally different than the way it should look on IE7. Question one: Basically, what I am asking everyone is what route should I take to learn how to properly build the website? Build as in put it togehter with CSS standards and HTML standards that will make my site look the same on every brwoser. (Not only learning standards but where can I learn to properly write my code?) Where is a strong free resource I can use to learn how to these things? Question two: How do I properly code my website? Do I use all external style sheets to make dynamic page design simplistic or do I hard code some things into the DIV tags on each page? What is proper? Oh, and if anyone has any tutorials on how to properly design a complete layout feel free to throw it in a response somewhere. Thank you for taking the time to read my questions, and hopefully you will understand what I am trying to get out to everyone. I need to get on the right route of the designing side of web programming so that I will know how to create successful websites in the future. Thank you, Sam Pardee

• Need some help for the issues that caused because of secret key in rails application

  I have a weird problem. I have a rails application. When I am trying to run the ruby script/about command, it is displaying the details when the secret key in config/initializers/session_store.rb was removed or commented. When I place the secret key in the file and if i runs the ruby script/about command it is throwing error as c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependenc es.rb:443:in `load_missing_constant': uninitialized constant ActionController ( ameError) from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_supp rt/dependencies.rb:80:in `const_missing' from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_supp rt/dependencies.rb:92:in `const_missing' from D:/chat/config/initializers/session_store.rb:13 from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `g m_original_require' from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `r quire' from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_supp rt/dependencies.rb:156:in `require' from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_supp rt/dependencies.rb:521:in `new_constants_in' from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_supp rt/dependencies.rb:156:in `require' ... 7 levels... from c:/ruby/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/commands/about.rb:1 from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `g m_original_require' from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `r quire' from script/about:3 In config/initializers/session_store.rb file the error is shown for the below code.

• Rails 2.3 session

  - by Sam Kong

  Hi, I am developing a rails 2.3.2 app. I need to keep session_id for an order record, retrieve it and finally delete the session_id when the order is completed. It worked when I used cookies as session store but it doesn't for active_record store. (I restarted my browser, so no cache issue.) I know rails 2.3 implements lazy session load. I read some info about it but am still confused. Can somebody clarify how I use session_id for such a case? What I am doing is... A user make an order going through several pages. There is no sign-up, neither login. So I keep session_id in the order record so that no other user can access the order. @order = Order.last :conditions = {:id = params[:id], :session_id = session[:session_id] } When the order is finished, I set nil to session_id column. How would you implement such a case in lazy session(and active_record store) environment? Thanks. Sam
