• DataType for storing a long serial number (10 bytes)

  - by CrimsonX

  We have a device which has a 10 byte serial number which must be read into our application and stored into a .net datatype. In the device it is stored as an unsigned 10-byte (80-bit) number. I don't expect we will be performing any mathematical operations on this number, but only displaying it to the user. The .NET framework doesn't have a built in UNIT128 to store this datatype. My suggestion for storing this datatype is to create a 10 element byte array and read in the data into this array. Are there any better solutions to this problem? Note: I have seen in this question that a GUID is a 128 byte signed integer, but it seems like a bad idea to use a GUID in this fashion. Any other suggestions?

• How do I show/hide an element in YUI as in jQuery?

  - by Chad Johnson

  In jQuery, when I want to show or hide something, I do this: $('#elementId').show(); $('#elementId').hide(); How do I do this with YUI? I've tried YAHOO.util.Dom.get('elementId').hide(), asked my co-workers, looked at the documentation, and searched Google, and I've found nothing helpful. From the documentation, it looks like this should work YAHOO.util.Dom.get('elementId').setStyle('display', 'none') but of course it does not. All I can think of is this, which sucks because then I'm not using a framework: document.getElementById('elementId').style.display = 'none';

• Using numeric values to select item from a dropdown box with JavaScript

  - by Shyam

  Hi, I have a multitude of dropdown boxes within my webpage. One of these dropdown boxes is used for a single selected value out of a list of options. <SELECT id="Box0" name=""> <OPTION value="0">none</OPTION> <OPTION value="1">first</OPTION> <OPTION value="2">second</OPTION> </SELECT> How can I add an event to this section, so when it is in focus, I could use numeric keys like 1,2.. to select an option instead of using the mouse or arrow keys for selecting an option? For clarification: if I press "1" on my keyboard, the selected value would become "first", with "2" the selected value becomes "second". I choose not to use a library/framework such as JQuery/Mootools. Thanks,

• Do you take the pain of learning it or use an out of the box solution?

  - by Mantorok

  Hi all What I'm getting at here is being presented with a control or framework that does 95% of what you want but has its shortcomings when opposed to learning how to do it yourself. To give a good example (ASP.Net) UpdatePanel vs DIY JS/JSON. The UpdatePanel gives you AJAX instantly without doing anything additional, however I've come to learn that its shortcomings are mainly that it's a bit of a hack and performs badly on busy pages and I've found myself having to scrap UpdatePanels in favour of rolling my own JS, and I've now made it a habit to fully investigate any shortcomings in out-of-the-box solutions, as I've been stung by this experience. So I guess what I'm asking is: Is it better to find out how to DIY or is it considered a better approach to try the available solution and risk going a full circle? Obviously I've only targetted a single control, but it is a very attractive control to people learning AJAX - I'm sure there are others out there. Sorry if dupliate. Thanks

• Code generating SOAP Web Service Proxy objects yourself - C#/.NET 3.5/T4

  - by tyndall

  Is there a framework or code already available that will give me more control over the code that gets generated based off my web references? I'm working at a new company. And the Web Services Proxies are all self contained in their own assembly. I would really rather generate this whole project. Every time they change something on the Services-side (Java) the WSDL references have to be dropped and re-added. (I can't figure out what those guys are doing on their end that messes with the WSDL bad enough that this needs to be done so much) Their are 10 of these references. I'd rather codegen the whole thing at compile time. Every time. What are my options?

• Performance - User defined query / filter to search data

  - by Cagatay Kalan

  What is the best way to design a system where users can create their own criterias to search data ? By "design" i mean, data storage, data access layer and search structure. We will actually refactor an existing application which is written in C# and ASP .NET and we don't want to change the infrastructure. Our main issue is performance and we use MSSQL and DevExpress to build queries. Some queries run in 4-5 minutes and all the columns included in the queries have indexes. When i check queries, i see that DevExpress builds too many "exists" clauses and i'm not happy with that because i have doubts that some of these queries skip some indexes. What may be the alternatives to DevExpress? NHibernate or Entity Framework? Can we build dynamic criteria system and store these to database in both of them ? And also do we need any alternative storage like a lucene index or OLAP database?

• Compare values in each column of two Oracle Types

  - by colinjameswebb

  I've been playing around with the pluto-test-framework today, and I'd like to get some existing functions into a test harness with it. I have lots of functions with this type of specification. FUNCTION DO_SOME_STUFF (pOldSchedule IN SCHEDULE_OBJ, pNewSchedule OUT SCHEDULE_OBJ, pLoggerContext IN OUT LOGGER_CONTEXT_OBJ) RETURN NUMBER; It takes pOldSchedule, does some stuff to it, and then returns pNewSchedule. The logger_context just does logging. As part of a test, I'd like to be able to compare the values in each of the columns of the type, without having to write individual IF statements. It'll need to return boolean to signify whether or not pOldSchedule and pNewSchedule match. Any ideas?

• Migrating shape sql to something equally powerful

  - by daRoBBie

  Hi, we are currently investigating a migration of an application that doesn't meet company standards. The application is built using VB6 and Shape SQL/Access. The application has about 120 reports by storing Shape SQL strings in a database which the user can modify using a wizard. Shape sql is not allowed at this company. We have investigated plain SQL, Linq, Entity Framework as alternatives... but all result in more complex solutions. Does anyone have another suggestion? Update: Shape SQL is an ADO command to get hierarchical datasets, for further info: http://support.microsoft.com/kb/189657

• .htaccess URL is being cut at a space (I'm using Codeigniter)

  - by Ice

  I've used the following code to map https://live.example.com on to http://example.com/api Options +FollowSymLinks RewriteEngine On RewriteCond %{HTTPS} =on RewriteCond %{HTTP_HOST} ^live\.example\.com [NC] RewriteRule (.+)$ "http://example.com/api/$1" [L,P] The following url: https://live.example.com/userlinks/xml/John%20James/MvPjeUTo15/ Is suppose to map onto: http://example.com/api/userlinks/xml/John%20James/MvPjeUTo15/ Instead it maps it to: http://example.com/api/userlinks/xml/John So it seems to cut it at the space. I am using the Codeigniter framework but I am not sure if the problem lies there. Also using %20 or just a space in the url bar produces no different results. Anyone any idea and/or solution why this happens? Thank you very much, Ice

• Is it possible to use HTTPS certificates for licensing?

  - by Ton van den Heuvel

  I am working on an application with multiple clients and a server running various web-services for the clients. To implement licensing I am thinking about using HTTPS as a protocol for the web-services using certificates that are issued by our company. By influencing the expiration date of a certificate for a client we can prevent them from using our software after their license term. It this possible and does it make sense to you? Additional information: I am planning on using Qt/C++ for the clients, and the Twisted framework for the web-services.

• Enable Query Strings in Code Igniter

  - by tarnfeld

  Hey, I am trying to implement Twitter's OAuth into my Code Igniter web application at which the callback URL is /auth/ so once you have authenticated with Twitter you are taken to /auth/?oauth_token=SOME-TOKEN. I want to keep the nice clean URL's the framework provides using the /controller/method/ style of URL but I want to enable query strings as well, there will only ever be one name of the data oauth_token so it's ok if it has to be hard coded. Any ideas? I have tried tons of the things people are saying to do, but none work :( PS: I'm using the .htaccess method of URL rewriting.

• xcode collect2: ld returned 1 exit status - how to resolve?

  - by Remover

  From what I have read this is supposed to be when the linker (not exactly sure how that works) can't find a symbol. the symbol in question is: SCNetworkReachabilityCreateWithAddress as can be seen from the full error message below. the thing is that the correct framework is added to my target. xcode recognises the symbol OK, i.e. there is no error message in the .m file. the .m file is added to the correct target so I'm not at all sure what to do. Any ideas please? "SCNetworkReachabilityCreateWithAddress", referenced from: -[AppWelcomeVC viewDidLoad] in AppWelcomeVC.o ld: symbol(s) not found collect2: ld returned 1 exit status

• JSF and Ajax4JSF on WebSphere 6.1 --> Problem with Form Submission

  - by Shamik

  Has anyone setup JSF1.1 with Ajax4JSF on websphere 6.1 ? I followed the instructions as mentioned in the developer guide . The problem that I am facing is that once I use a4j:support on any of my h:inputText item, the form values are not getting set in the backing bean on the submission of the form. I do have <h:messages> tag present just above the form so that all the problems should be reported there but I do not see any error message once I submit the form. But I do see that the values are not getting set. I need to find the solution as early as possible otherwise I probably have to throw the ajax4jsf framework and write javascripts instead :(

• Performance impact of rewrite conditions?

  - by makeee

  My web framework (cakephp) uses the following rewrite conditions and rule: RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?url=$1 [QSA,L] I serve up a lot of image files (~10 a second). I'm wondering if it would improve performance to have a rewrite rule that exempted requests for files in my images directory from even trying those rewrite conditions (checking whether the file exists). My traffic is constantly fluctuating, so this would be hard to benchmark, which is why I thought I'd ask here. If that would be beneficial, how might I exclude files in "/images" directory from trying those conditions and rewrite rule?

• How to generate a user role grid

  - by Svish

  I have the following tables: users (id, username, ... ) roles (id, name) roles_users (user_id, role_id) I am wondering how I can create a nice sort of user-role-grid from that which an admin can use to administer roles to users in a clear way. What I would like is basically a table full of checkboxes sort of like this: Login Editor Admin Alice ¦ ¦ ¦ Bob ¦ ? ? Carol ¦ ¦ ? [Apply] Generating the table isn't too much of a deal, but I am very unsure how to handle it when it comes to how to name all the checkboxes and especially how to read and update the database in a not too clumsy way. Does anyone have any good advice or pointers on how to do this in a mostly clean way? I'm using the Kohana 3 framework, if there is anything there that can make this even easier, but I of course welcome any answer.

• Visual Studio 2010 ClickOnce prerequisites from same location

  - by muhan

  I'm using clickonce publishing and want to require .net 3.5 framework and others as prerequisites. I have selected the option to download the prerequisites from same folder as my app. I've also placed the .net 3.5 redistributable exe in the folder on the server where the app will be published. I publish by FTP over the internet to the server where the users are. However, VS will not let me publish saying it can't find the prerequisites on disk. Does this mean I have to have the prerequisites installed somewhere on my developer machine and that those files will all be uploaded by FTP to the server everytime I publish a new version to the server? That would be a huge amount of data to upload over my slow DSL upload link. Any insight?

• Building a professional company website

  - by Sphynx

  Hi fellows, I want to create a professional website for my company. I'm not a designer. I know some html/css, but I don't have much experience making up advanced pages and layouts. I'd expect public area, with various articles, and a "customer zone", accessible via username and password, where clients will be able to track their orders and download files. It needs to look very modern. I don't want to use website templates, because they're too simple. I know some Wordpress, but that's mostly for blogs, and anyways you need to find a right theme besides the CMS itself... Is there any alternative solution, some kind of framework for building such portals? Preferably a system that doesn't require designer skills. Thanks!

• Need an Asp.net MVC Application solution

  - by Daoming Yang

  I have implemented a small ordering and stock control system (for internal using) with the MVC 2 framework. Now my friends, they want to have a website to present the existing products for their customers. I know, I know they will ask me to do this one day. So in the beginning, I have made the controller name to start with "Admin". But now I am not sure the best way to implement their requirements. Could you advise me? 1.For the security reason, I did not allowed anonymous user to access the website a part from the CSS and image files. My question is the controllers' name are not folders' name, how could I set this up? 2.I'm planning to put the admin section into an "area" and will it be a good way to go? Can anyone provide me some suggestions. Many thanks.

• How to distinguish properties from constants if they both use PascalCasing for naming?

  - by Gishu

  As stated in the framework design guidelines and the WWW in general, the current guideline is to name your constants like this LastTemplateIndex as opposed to LAST_TEMPLATE_INDEX With the PascalCasing approach, how do you differentiate between a Property and a Constant. ErrorCodes.ServerDown is fine. But what about private constants within your class ? I use quite a lot of them for naming magic numbers.. or for expected values in my unit tests and so on. The ALL_CAPS style helps me know that it is a constant . _testApp.SelectTemplate(LAST_TEMPLATE_INDEX); *Disclosure: I have been using the SCREAMING_CAPS style for a while for constants + I find it more readable than squishedTogetherPascalCasedName. It actually STANDS_OUT in a block of text*

• How to debug macruby?

  - by Dan

  Hi, I've encountered an inconsistent bug with MacRuby and have no idea how to go about debugging this. If anyone could help would be great. I don't know if this is due to my own code or is it a bug in the MacRuby framework. I have a feeling it's my own code, something about over-retaining a piece of memory and hence the garbage collection failed. This is the error from Xcode. Thanks.
