  • 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.

  • Showing an image after loading it from sql database

    - by user330075
    I have a problem showing the image form database in a view Details and a ImageController. Inside the view I have: img src=Url.Action("GetFile","Image", new {id= Model.id}) and in controller: public FileContentResult GetFile(int idl) { //int idl = 32; SqlDataReader rdr; byte[] fileContent = null; ........... return File(,,); } When the view is called, function GetFile it just won't work. But if I cut out the parameter int id1 and I instantiate it as a variable it does work. public FileContentResult GetFile() { int idl = 32; SqlDataReader rdr; byte[] fileContent = null; ........... return File(,,); } Why?

  • ProgressBar while transferring data from Excel sheet to SQL database table

    - by Sagar patel
    Can anyone tell me how to show animated progress bar while the data from an Excel sheet to a SQL database table is being transfered? I have a form in .aspx page. In that form, there is one FileUpload control that uploads an Excel file. While uploading that file and saving it on the server at the same time I'm transferring the data from the Excel sheet to a SQL table. During this transfer, I want to show a ProgressBar and after transferring all data it will be removed automatically.. Is there something I can do to achieve this?

  • android, find the nearest location without going through all the locations

    - by Marwan
    I am building a taxi dispatching app first: I need the passenger app to show the nearest taxis, now I know how to do that in code but in my way I have to go through all the taxis locations(in database on server) and calculate the distance from the passenger location and get the lowest ones - I don't want to do this because there will be a lot of taxis and going through all of them and making some math is kind of pain on the server- is there a way to get the nearest ones without going through all of them? second: what the best database to use - first, should it be sql or non-sql - I need a very robust database, because there will be a lot of updates (I mean the passengers locations added then deleted when arriving to destination && the taxis location changes frequently) finally: I will use RubyOnRails to do the server side and json as data transfer format, do you have a recommendation to me on something better? Thanks

  • Getting a permission error when trying to connect to sql database

    - by Matt
    I have a sql server on a dedicated machine, running SQL 2008. I have the IP of the box, a database setup on it. I've built a small script that just does a connection test, and when I run it, I get the following error. Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. I've been told by the admin that SQL remote access has been granted for my IP address. Anybody know what's wrong?

  • Web service accessing client database

    - by chupinette
    Hello all! I am new to web services and i have a question: Should a web service be able to access the client database? Sorry if i am not using the proper terms. Lets say i have a web service method called : GetCarDetails(string name) which will actually return details from car table. in this method i have an sql statement like SELECT * FROM car WHERE name = ?. In the client application, i have a textbox where i can input a name and a button on which when i click, fill a gridview. So im kinda confused, should the web service normally know that the client has a table called car?Please correct me if ive used the wrong terms. Thanks

  • Turn database result into array

    - by Industrial
    Hi everyone, I have just made the update/add/delete part for the "Closure table" way of organizing query hierarchical data that are shown on page 70 in this slideshare: http://www.slideshare.net/billkarwin/sql-antipatterns-strike-back My database looks like this: Table Categories: ID Name 1 Top value 2 Sub value1 Table CategoryTree: child parent 1 1 2 2 2 1 However, I have a bit of an issue getting the full tree back as an multidimensional array from a single query. Here's what I would like to get back: array ( 'topvalue' = array ( 'Subvalue', 'Subvalue2', 'Subvalue3' = array ('Subvalue 1', 'Subvalue 2', 'Subvalue 3' ) ); ); Update: Found this link, but I still have a hard time to convert it into an array: http://karwin.blogspot.com/2010/03/rendering-trees-with-closure-tables.html

  • Hibernate database connection configuration

    - by Alvin
    We have 2 different server environments using the same Hibernate configuration. One server has JNDI support for datasource, but the other does not. Currently the Hibernate configuration is configured to use JNDI, which is causing problem on the server that does not support JNDI. I have also tried to put the direct JDBC configuration together with JNDI configuration into the configuration file, but it looks like hibernate always favors JNDI over direct JDBC configuration if both exist. My question is, will it be the same if both JNDI and connection_provider configuration both exists? Will Hibernate still use JNDI over connection_provider? Or is there any way to change the precedence of the database connection property? I do not have access to the server all the time, so I thought I do ask the question before my window of the sever time. Thanks in advance.

  • set up way of getting mysite.$domain

    - by jose silva
    Hi I have several domains, only one website and one databse table for each domain. example: wbesite.us - data from USA goes to database table main_usa wbesite.co.uk - data form UK goes to database table main_uk Only have one database with name of the website. Having only one website structured, and having variables like $sql="select * from main_".$countrycode." where bla..bla..., and many other variables to catch the domain extension, and so on... Now, instead of having one full website for each domain, how can set a script and wher do I put it in order to detect the domain that the user uses. In my server root do I create something like website.$domain ? Something like website OLX but for different purposes. I hope I made myself clear. Thank you.

  • Full stack framework for Java

    - by Jonathan Barbero
    Hello everyone, I'm looking for a full stack framework (from persistency to view generation (CRUD)) for Java. I don't have experience with Rails style frameworks, like Grails, but I worked a lot with Hibernate, Struts, Spring ... I prefer a framework that let you naturally modify the business domain design with the less effort ( i.e. writing the sql querys to modify the tables and constrains, change the view pages, etc ... ). I was looking a bit about this topic, I saw Naked Objects for example but its development has stopped. So, I want to hear about your experience. Thanks in advance.

  • Loading large amounts of data to an Oracle SQL Database

    - by James
    Hey all, I was wondering if anyone had any experience with what I am about to embark on. I have several csv files which are all around a GB or so in size and I need to load them into a an oracle database. While most of my work after loading will be read-only I will need to load updates from time to time. Basically I just need a good tool for loading several rows of data at a time up to my db. Here is what I have found so far: I could use SQL Loader t do a lot of the work I could use Bulk-Insert commands Some sort of batch insert. Using prepared statement somehow might be a good idea. I guess I was wondering what everyone thinks is the fastest way to get this insert done. Any tips?

  • Books on data-intensive enterprise integration patterns

    - by Tristan
    I'm trying to understand design patterns used by data-intensive enterprise applications. A classic example is the financial industry, where system must consume, analyze, and execute on real-time financial data while providing information and configuration options to a broad set of traders and analysts. One can imagine similar system in airlines, major supply chain operations, and utility providers. Are there good books that provide and inside view of how these systems work? Enterprise Integration Patterns is one example, but I'm looking for something with more real-world applications, particularly in finance.

  • Lazy loading? Better avoiding it?

    - by Charlie Pigarelli
    I just read about this design pattern: Lazy Load. And, since in the application i'm working on i have all the classes in one folder, i was wondering if this pattern could just make me avoiding the include() function for every class. I mean: It's nice to know that if i forgot to include a class, PHP, before falling into an error, trough an __autoload() function try to get it. But is it fine enough to just don't care about including classes and let PHP do it by your own every time? Or we should write __autoload() just in case it is needed?

  • Archiving Database Tables using Java

    - by HonorGod
    My application demands archiving database tables between sybase and db2 and vice-a-versa and within(db2 to db2 and sybase to sybase) using java. I am trying to understand the best strategies around in terms performance, implementation, ease of use and scalability. Here is my current process - source and destination tables with the acceptable parameters (from java) are defined within xml. the application reads the source and destination configurations and execute them sequentially. destination is sometime optional when source is just deleting data from a specific table or when the source is just calling a stored procedure. dataset between source and destination is extremely large (in millions) From top of my head, it looks like I can define dependencies between multiple source and destination combination and have them execute in parallel in multiple treads. But will this improve any performance(i hope it will)? Are there any open-source frameworks for data archiving using java? Any other thoughts on the implements side will be really helpful. Thanks

  • SQL Server 2005 to 2008 Bak file help please!

    - by Brandon
    I have a SQl Server 2005 database backup that I want to transfer to SQL Server 2008 on my server. I spent 3 days transferring the .bak file from my own machine to my server. I then tried to restore the bak file and I got an error. I then read online a completely different method for adding a SQL server 2005 Database to SQL server 2008 which was the detach and attach method which means I need to detach the database in SQL Server 2005 and then transfer the MDF file from it via ftp to my server and then attach it in SQL Server 2008. Well I already used a lot of bandwidth transferring the .bak file to my server. is there a way to convert my .bak file which is already on my server to an MDF file and attach it in SQL server 2008?

  • SQL Script To Generate a Database Dictionary **With Linked Fields**

    - by Albert
    I would like to generate a Data Dictionary for a SQL Server 2008 database that has one row for each field, and the following columns: table_name field_name data_type link_table (for when the field in question is a foreign key) link_field (for when the field in question is a foreign key) I can get the first 3 columns with something like the SQL script below...but I don't know how to get the last two columns of foreign key information. INFORMATION_SCHEMA.TABLE_CONSTRAINTS gets close, but doesn't have the data I'm looking for. Can someone help with this point? SELECT TABLE_NAME,COLUMN_NAME,DATA_TYPE FROM INFORMATION_SCHEMA.COLUMNS Secondarily if anyone has any suggestions on additional fields which would be helpful please post.

  • Open source framework à la Microsoft Sync Framework suggestions?

    - by drskol
    We are implementing a warehouse management system atop an open source stack (Java, web services & friends). In this system, we want to integrate many mobile devices which should also be capable of adequate online/offline functionality, e.g. preparing database inserts while a mobile device is temporarily unconnected, and performing them on the backend database when reconnected. For a .NET stack, Microsoft Sync Framework would be a perfect solution, e.g. to do database replication and hoarding. Can anyone suggest an open source alternative to the MS Sync Framework and possibly describe his experiences with it? Thanks in advance for any answers.

  • Windows Phone: Updating backend datastore (via web service) while keeping UI very responsive

    - by will
    I am developing a Windows Phone app where users can update a list. Each update, delete, add etc need to be stored in a database that sits behind a web service. As well as ensuring all the operations made on the phone end up in the cloud, I need to make sure the app is really responsive and the user doesn’t feel any lag time whatsoever. What’s the best design to use here? Each check box change, each text box edit fires a new thread to contact the web service? Locally store a list of things that need to be updated then send to the server in batch every so often (what about the back button)? Am I missing another even easier implementation? Thanks in advance,

  • Check if edit is valid for database ms-access

    - by twodayslate
    I want to be able to check if I can edit a cell in a database with a new object Example method declaration: something.isValid(Object newObject, row, column); Example cases: If the editing cell stores an Number and I give it a String, the method will return false... If the editing cell has to be different than every other entry and the new object is the same as something else, the method will also return false.... My main goal... I want to check a whole row, and if everything is valid, I will edit the whole row. Right now, the only way I can find out if I can actually edit something is by actually editing it and seeing if I get an error.

  • MVC Forms Authentication with custom database

    - by AndrewVos
    I'm trying to get forms authentication working for an mvc site. I have a custom database with a users table, and I would like to do my own password validation. I am logging in my user like this: if (PasswordHasher.Hash(password) == dataUser.Password) { FormsAuthentication.SetAuthCookie(email, true); return true; } The problem is, when the session expires obviously the user has to login again. I am thinking I should be storing this Auth cookie in my users table? Update: I'm obviously in desperate need of more education in this area. I just noticed that the user stays authenticated even after an iisreset. I guess what I'm asking is how can I get persistent and non persistent authentication working properly. I want a user to not have to login again if they click "remember", and if they don't then their authentication should expire when the forms authentication is set to expire.
