  • Handling auto-incrementing IDENTITY SQL Server fields with LINQ to SQL in C#

    - by Maxim Z.
    I'm building an ASP.NET MVC site that uses LINQ to SQL to connect to SQL Server, where I have a table that has an IDENTITY bigint primary key column that represents an ID. In one of my code methods, I need to create an object of that table to get its ID, which I will place into another object based on another table (FK-to-PK relationship). At what point is the IDENTITY column value generated and how can I obtain it from my code? Is the right approach to: Create the object that has the IDENTITY column Do an InsertOnSubmit() and SubmitChanges() to submit the object to the database table Get the value of the ID property of the object

  • Best data store for billions of rows

    - by Jody Powlette
    I need to be able to store small bits of data (approximately 50-75 bytes) for billions of records (~3 billion/month for a year). The only requirement is fast inserts and fast lookups for all records with the same GUID and the ability to access the data store from .net. I'm a SQL server guy and I think SQL Server can do this, but with all the talk about BigTable, CouchDB, and other nosql solutions, it's sounding more and more like an alternative to a traditional RDBS may be best due to optimizations for distributed queries and scaling. I tried cassandra and the .net libraries don't currently compile or are all subject to change (along with cassandra itself). I've looked into many nosql data stores available, but can't find one that meets my needs as a robust production-ready platform. If you had to store 36 billion small, flat records so that they're accessible from .net, what would choose and why?

  • Extjs - Loading Grid when call

    - by Oxi
    I have form and grid. the user must enter data in form fields then display related records in the grid. I want to implement a search form, e.g: user will type the name and gender of the student, then will get a grid of all students have the same name and gender. So, I use ajax to send form fields value to PHP and then creat a json_encode wich will be used in grid store. I am really not sure if my idea is good. But I haven't found another way to do that. The problem is when I set autoLoad to true in the store, the grid automatically filled with all data - not just what I asked for - So, I understand that I have to set autoLoad to false, but then the result not shown in the grid even it returned successfully in the firebug! I don't know what to do. My View: { xtype: 'panel', layout: "fit", id: 'searchResult', flex: 7, title: '<div style="text-align:center;"/>SearchResultGrid</div>', items: [ { xtype: 'gridpanel', store: 'advSearchStore', id: 'AdvSearch-grid', columns: [ { xtype: 'gridcolumn', dataIndex: 'name', align: 'right', text: 'name' }, { xtype: 'gridcolumn', dataIndex: 'gender', align: 'right', text: 'gender' } ], viewConfig: { id : 'Arr' ,emptyText: 'noResult' }, requires: ['MyApp.PrintSave_toolbar'], dockedItems: [ { xtype: 'PrintSave_tb', dock: 'bottom', } ] } ] }, My Store and Model: Ext.define('AdvSearchPost', { extend: 'Ext.data.Model', proxy: { type: 'ajax', url: 'AdvSearch.php', reader: { type: 'json', root: 'Arr', totalProperty: 'totalCount' } }, fields: [ { name: 'name'}, { name: 'type_and_cargo'} ] }); Ext.create('Ext.data.Store', { pageSize: 10, autoLoad: false, model: 'AdvSearchPost', storeId: 'AdvSearchPost' });

  • Best way to store application images taken via camera

    - by Dave
    Hi all, I'm just looking for some insight into what would be the best way for me to store images as part of my app. I have an activity that represents a 'Job' which has a couple of edittext's and underneath was planning on using the Gallery component to show images relevant to this job. The job data is stored in a database (on the sdcard) so was also thinking of creating a table to store 'JobImages' and having each image stored as a byte array. But I'm not sure if it would be better to store the images directly on sdcard under a folder structure specific to my application and the job. E.g. using the job ID number as a folder name. Depending on which method I use will greatly determine the code that goes into an 'adapter' that allows me to bind to the gallery component so before I begin I was wondering if anyone has had the same design problem and what option they chose. Thanks, Dave

  • iPhone app store approval - coredata design change

    - by satyam
    I created an app, uploaded to app store and approved by app store as well. Its ready for download. The app is based on coredata. Now I changed the design of the app to add new functionality. Changes include addition of new attributes to current entities, deletion of few entities etc. Now, if I upload the app to app store, does it approve or not? Do I have to put and Note saying that "Please uninstall old version and install new version?" Will my app be approved first of all or not.

  • Store data in Ruby on Rails without Database

    - by snowmaninthesun
    I have a few data values that I need to store on my rails app and wanted to know if there are any alternatives to creating a database table just to do this simple task. Background: I'm writing some analytics and dashboard tools for my ruby on rails app and i'm hoping to speed up the dashboard by caching results that will never change. Right now I pull all users for the last 30 days, and re arange them so I can see the number of new users per day. It works great but takes quite a long time, in reality I should only need to calculate the most recent day and just store the rest of the array somewhere else. Where is the best way to store this array? Creating a database table seems a bit overkill, and i'm not sure that global variables are the correct answer. Is there a best practice for persisting data like this? If anyone has done anything like this before let me know what you did and how it turned out.

  • How to store matrix information in MySQL?

    - by dedalo
    Hi, I'm working on an application that analizes music similarity. In order to do that I proccess audio data and store the results in txt files. For each audio file I create 2 files, 1 containing and 16 values (each value can be like this:2.7000023942731723) and the other file contains 16 rows, each row containing 16 values like the one previously shown. I'd like to store the contents of these 2 file in a table of my MySQL database. My table looks like: Name varchar(100) Author varchar (100) in order to add the content of those 2 file I think I need to use the BLOB data type: file1 blob file2 blob My question is how should I store this info in the data base? I'm working with Java where I have a double array containing the 16 values (for the file1) and a matrix containing the file2 info. Should I process the values as strings and add them to the columns in my database? Thanks

I want to be able to show the number of tickets submitted divided by the number of users in each country. Any ideeas how to do that? Thank you very much, Razvan

  • when using exchange 2010 it complains of not talking to Information Store service on exchange 2007

    - by ChrisMuench
    I am attempting to do an upgrade in my org from exchange 2007 to exchange 2010. I moved all the mailboxes and made sure my certificates were setup in exchange 2010. I then changed my ip forwarding rules to forward mail to my exchange 2010 box. I can receive email. I then powered off my exchange 2007 server. However now when I open my exchange 2010 console it is complaing of not being able to talk to the Information Store service on my exchange 2007 server. What is up? do I have to tell exchange somewhere "who" is the new exchange server? I'm confused. I hate it when software does it automatically. I want to force it to do something.

  • How to browse the iTunes Store without iTunes?

    - by Another Registered User
    Sometimes I just want to see an App description, and when I click on it, my browser goes to a page from Apple which immediately starts to screw up my machine. Reason: Heavy iTunes launches and eats up 95% of my system resources. Beach ball for minutes! And now I want to browse podcasts and it makes me so angry that I can't just have a normal browser. For example, inside iTunes I can't open things in a new window so that I don't get lost from where I came from. It's so limited and memory consuming. Maybe there's a way how to browse the iTunes store contents with a normal web browser?

    - by Carlos
    I just updated to Mac App Store 1.0.2 with the update to 10.6.8. The Mac App Store said I have one update available, for Angry Birds.... I do not have Angry Birds on my system, but when I clicked the update button I got the following message. "You have updates available for other accounts. Sign in to [email protected] to update applications for that account." Needless to say this account does not exist. Any ideas what this is all about?

  • CDN or seperate site to store static content?

    - by marty
    If I understand this correctly, I have two options for static files: Use a CDN and throw all my static files on it. Use a separate domain just to store the static files so users can download it simultaneously. So I assume it is either one to choose or do i need a separate domain then use a CDN to get files from that domain? Because I assume even if I have a CDN I still need to have a local copy of the static content somewhere either on my main site or a static content site like static.domain.com?

  • Skype message sync and notifications - Windows 8

    - by Raykud
    The problem is that my messages don't seem to sync and neither do I get notifications from the Windows Store App. I have both, the desktop program and the Windows Store App, the problem is that whenever someone messages me I do not receive a notification of the App but I get one from the desktop program. The Skype app is running in the background and does not have disabled the notifications neither have turned on sleep notifications. I have to manually open the app and moreover, open the chat window of the one who is talking to me, then wait like 10 minutes and then the chat will get syncronized. in short: Notifications don't work even: if computer unlocked and Skype is running in background if computer unlocked and Skype is running in foreground These doesn't seem to help: Reboot doesn't affects skype. Having only the App opened. Uninstalling/reinstalling Is there a way to fix this? or is this an issue with the Skype app in Windows 8?

    I am currently using Windows 8 on my desktop PC. I want to upgrade to Windows 8.1. I heard that Microsoft provides this update through Microsoft Store for free. But in My home I don't have a faster internet connection. I downloaded a Windows 8.1 ISO from cafe, but when I started installing, it asks for a key. I typed my original Key for windows 8, but it didn't work. Is there any way for me to update to Windows 8.1 without an internet connection and without purchasing another key? Thank you

  • Switching from Amazon EC2 instance-store to EBS Volume

    - by Adam
    Hi, I have an Amazon EC2 instance that is using an instance-store as its root device. It has no EBS volumes attached to it. It has a database and a running web application on it. If I understand correctly this is a bad setup as I would lose all the data on the instance if it were to reboot. I would like to correct this mistake. I'd like to move all the data on the running instance to a new EBS volume and make that new volume the root device. How do I go about doing this? Thanks!

  • Capture RTSP stream from IP Camera and store

    - by Keerthi
    I've got a few IP Cameras which output an RTSP (h264 mpeg4) stream. Hitting the URL locally via VLC: rtsp://192.168.0.21:554/mpeg4 I can stream the camera and dump to disk (on my desktop). I'd like to however store these files on my NAS (FreeNAS). I was looking at ways to capture the RTSP stream and dump them to disk but I'm unable to find anything. Is it possible to capture the stream on FreeBSD or Linux (RaspberryPi) and dump the streamed content to a disk local to Linux or FreeBSD - preferably every 30minutes? EDIT: The NAS is headless (HP N55L or something) and the RaspberryPi's are headless too. I've already looked into ZoneMinder but need something small. I was hoping maybe using Motion to detect motion on the stream but that will come later.

  • Can GnomeKeyring store passwords unencrypted?

    - by antimeme
    I have a Fedora 15 laptop with the root and home partitions encrypted using LUKS. When it boots I have to enter a pass phrase to unlock the master key, so I have it configured to automatically log me in to my account. However, GnomeKeyring remains locked, so I have to enter another pass phrase for that. This is unpleasant and completely pointless since the entire disk is encrypted. I've not been able to find a way to configure GnomeKeyring to store its pass phrases without encryption. For example, I was not able to find an answer here: http://library.gnome.org/users/seahorse-plugins/stable/index.html.en Is there a solution? If not, is there a mailing list where it would be appropriate to plead my case?

  • Where does truecrypt store the backup volume header?

    - by happygolucky
    When using WDE, where does (if anywhere) truecrypt store a backup volume header? As i know there is always a backup header for regular truecrypt volumes, however i am not sure if this applies when system encryption is used. Because if i damage the volume header in track 0, my password won't boot my system anymore. So there is no backup header on the drive? I read somewhere on a forum that truecrypt might have a backup header relative to some position from the END of the HDD, however this doesn't make sense as it could easily be wiped over by programs running in Windows. And how would truecrypt know where this backup is anyway?

  • How can you import a root certificate to a machine level store in Windows 7

    - by ReluctantAdmin01
    I have a service (Running as local system) that uses an SSL connection. Currently this connection fails because the remote host used a private CA to sign it's certificate. For previous operating systems, I used to use the certificate manager to import the CA cert into the local machine's Trusted Root certificates store. Though I can do the steps with a windows 7 machine, it seems after a reboot that the imported certificates are gone. Here are the steps I'm doing in Windows 7: Open mmc Add Certificates Snap-in for Local Machine Navigate to Third-Party Root Certification Authorities/Certificates Import Root CA Cert. The certificate seems to work fine, using internet explorer or the service to test the SSL connection works, but after a reboot it seems like the change is reverted.

  • Can I Store MediaWiki Files on the cloud?

    - by user219048
    I recently got a chromebook, and I've been brainstorming different ways to put mediawiki on it (with localhost, not a server). One way I've read about online is to go into developer mode to download and set up LAMP. I was wondering, wouldn't I be able to store the apache, mysql, php, and mediawiki files on the cloud (google drive)? And if so, would anything prevent me from accessing my wiki on any other computer's localhost, assuming I could just log into Google Drive to access these files? Might there be any reduced performance when operating from the cloud?

  • How to change Fluent NHibernate reference column name on a HasMany relationship using IHasManyConven

    - by snicker
    Currently I'm using Fluent NHibernate to generate my database schema, but I want the entities in a HasMany relationship to point to a different column for the reference. IE, this is what NHibernate will generate in the creation DDL: alter table `Pony` add index (Stable_ID), add constraint Ponies_Stable foreign key (Stable_Id) references `Stable` (Id); This is what I want to have: alter table `Pony` add index (Stable_ID), add constraint Ponies_Stable foreign key (Stable_Id) references `Stable` (EntityId); Where Stable.ID would be the primary key and Stable.EntityId is just another column that I set. I have a class already that looks like this: public class ForeignKeyReferenceConvention : IHasManyConvention { public void Apply(IOneToManyCollectionInstance instance) { instance.Cascade.All(); //What goes here so that I can change the reference column? } } What do I have to do to get the reference column to change?

  • WPF DataGrid ComboBox Column: Propagating Header Combobox throughout column...

    - by LostKaleb
    Hey there! Here's my question: I've got a Datagrid in WPF and I have a first column that is a DataGridComboBoxColumn. What I'd like to do is to have a header for that column also with a combobox: altering the header with propagate throughout the column. I can get this done visually, but when I submit the data, the list that is bound with the Datagrid does not carry the new combobox values. <dg:DataGridComboBoxColumn SelectedItemBinding="{Binding BIBStatus}" ItemsSource="{Binding Source={StaticResource typeStatus}}" Width="0.20*"> <dg:DataGridComboBoxColumn.HeaderTemplate> <DataTemplate> <StackPanel> <TextBlock Text="Built-In Bridge"/> <ComboBox SelectedItem="{Binding BIBStatus}" SelectionChanged="ComboBox_SelectionChanged" ItemsSource="{Binding Source={StaticResource typeStatus}}"/> </StackPanel> </DataTemplate> </dg:DataGridComboBoxColumn.HeaderTemplate> </dg:DataGridComboBoxColumn> In the ComboBox_SelectionChanged I have the following code: DataGridColumn comboCol = this.gridResults.Columns[0]; for (int i = 0; i < this.gridResults.Items.Count; i++) { ComboBox myCmBox = (comboCol.GetCellContent(this.gridResults.Items[i]) as ComboBox); myCmBox.SelectedValue = ((ComboBox)sender).SelectedValue; } When I submit the data, I submit the list that is DataContext to the Datagrid; if I change the value of the first column addressing a row at a time, i.e. clicking the cell with the combobox in each row, the values are propagated to the list in DataContext, however if I change the value of the first column by the header it does not. Can anyone tell me what I'm missing? I'm guessing it's the way I affect each row, but I've tried SelectedValue, SelectedItem and SelectedIndex... all to no avail. Thanks in advance...
