  • Schema compare with MS Data Tools in VS2008

    - by rdkleine
    When performing a schema compare having db_owner rights on the target database results in the following error: The user does not have permission to perform this action. Using the SQL Server Profiler I figured out this error occurs executing a query targeting the master db view: [sys].[dm_database_encryption_keys] While specifically ignoring all object types but Tables one would presume the SQL Compare doesn't need access to the db encryption keys. Also note: http://social.msdn.microsoft.com/Forums/en-US/vstsdb/thread/c11a5f8a-b9cc-454f-ba77-e1c69141d64b/ One solution would be to GRANT VIEW SERVER STATE to the db user, but in my case I'm not hosting the database services and won't get the rights to the server state. Also tried excluding DatabaseEncryptionKey element in the compare file. <PropertyElementName> <Name>Microsoft.Data.Schema.Sql.SchemaModel.SqlServer.ISql100DatabaseEncryptionKey</Name> <Value>ExcludedType</Value> </PropertyElementName> Anyone has an workaround this?

  • Get Instance from StructureMap by Type Name

    - by JC Grubbs
    Is there any way to request an instance from the StructureMap ObjectFactory by the string name of the type? For example, it would be nice to do something like this: var thing = ObjectFactory.GetInstance("Thing"); The use case here is a messaging scenario in which the message is very generic and contains only the name of a task. The handler receives the message, gets the task name from the message and retrieves the Type of task runner from a configuration database. StructureMap scans all the assemblies in a directory and one of them will contain the Type returned from the config database which then needs to be instantiated. The other possibility is to grab a Type instance by doing the following: var type = Type.GetType("Thing"); But the problem there is the assembly may or may/not be loaded in the AppDomain so that reflection call isn't always possible.

  • Visual Studio 2010: browse the web within VS?

    - by pcampbell
    Consider a developer who spends lots of time in Visual Studio. Hours are spent toiling on source code. Sometimes, he needs to search the web. Can you browse the web right within Visual Studio? Consider all modern versions and SKUs of Visual Studio. If so, are there any easy ways to launch that browser window? Are there any gotchas in terms of: CSS support rendering engine problems session/cookie problems

  • What is JDBC's Connection.isClosed() good for, and why is Snaq DBPool misbehaving on close?

    - by Uri
    I have the following code in Java: if(!conn.isClosed()) { conn.close(); } Instead of working, I am awarded with: java.sql.SQLException: Connection already closed My connection object is a Snaq.db.CacheConnection I checked the JavaDocs for isClosed, and they state that: This method generally cannot be called to determine whether a connection to a database is valid or invalid. A typical client can determine that a connection is invalid by catching any exceptions that might be thrown when an operation is attempted. So my questions are: 1) What good is JDBC's isClosed() anyway? Since when do we use Exceptions in Java to check for validity? 2) What is the correct pattern to close a database? Should I just close and swallow exceptions? 3) Any idea why would SnaqDB be closing the connection? (My backend is a Postgres 8.3)

  • getting count(*) using createSQLQuery in hibernate?

    - by JohnSmith
    I have several sql queries that I simply want to fire at the database. I am using hibernate throughout the whole application, so i would prefer to use hibernate to call this sql queries. In the example below i want to get count + name, but cant figure out how to get that info when i use createSQLQuery(). I have seen workarounds where people only need to get out a single "count()" from the result, but in this case I am using count() + a column as ouput SELECT count(*), a.name as count FROM user a WHERE a.user_id IN (SELECT b.user_id FROM user b) GROUP BY a.name HAVING COUNT(*) BETWEEN 2 AND 5; fyi, the above query would deliver a result like this if i call it directly on the database: 1, John 2, Donald 1, Ralph ...

  • Problem updating BLOB with Hibernate?

    - by JohnSmith
    hi, i am having problem updating a blob with hibernate. (i am using Hiberante 3.3.1-GA) my model have these getters/setters for hibernate, i.e. internally i deal with byte[] so any getter/setter convert the byte[] to blog. I can create an initial object without problem, but if I try to change the content of the blob, the database column is not updated. I do not get any error message, everything looks fine, except that the database is not updated. /** do not use, for hibernate only */ public Blob getLogoBinaryBlob() { if(logoBinary == null){ return null; } return Hibernate.createBlob(logoBinary); } /** do not use, for hibernate only */ public void setLogoBinaryBlob(Blob logoBinaryBlob) { ByteArrayOutputStream baos = new ByteArrayOutputStream(); try { logoBinary = toByteArrayImpl(logoBinaryBlob, baos); } catch (Exception e) { } } my hibernate mapping for the blob looks like <property name="logoBinaryBlob" column="LOGO_BINARY" type="blob" />

  • GWT - ListBox - pre-selecting an item

    - by rgoytacaz
    Hey there Stackoverflow, I got a doubt regarding pre-selecting(setSelectedIndex(index)) an item in a ListBox, Im using Spring + GWT. I got a dialog that contains a painel, this panel has a flexpanel, in which I've put a couple ListBox, this are filled up with data from my database. But this painel is for updates of an entity in my database, thus I wanted it to pre-select the current properties for this items, alowing the user to change at will. I do the filling up in the update method of the widget. I tried setting the selectedItem in the update method, but it gives me an null error. I've searched a few places and it seems that the listbox are only filled at the exact moment of the display. Thus pre-selecting would be impossible. I thought about some event, that is fired when the page is displayed. onLoad() doesnt work.. Anyone have something to help me out in here? Thx in advance, Rodrigo Dellacqua

  • Synchronize model in MySQL Workbench

    - by Álvaro G. Vicario
    After reading the documentation for MySQL Workbench I got the impression that it's possible to alter a database in the server (e.g. add a new column) and later incorporate the DDL changes into your EER diagram. At least, it has a Synchronize Model option in the Database menu. I found it a nice feature because I could use a graphic modelling tool without becoming its prisoner. In practice, when I run such tool I'm offered these options: Model Update Source ================ ====== ====== my_database_name --> ! N/A my_table_name --> ! N/A N/A --> ! my_database_name N/A --> ! my_table_name I can't really understand it, but leaving it as is I basically get: DROP SCHEMA my_database_name CREATE SCHEMA my_database_name CREATE TABLE my_table_name This is dump of the model that overwrites all remote changes in my_table_name. Am I misunderstanding the feature?

  • Creating an Android View with a particular style programmatically

    - by Casebash
    How can I create a view with a particular style programmatically (not in XML)? I tried using this [View (Context context, AttributeSet attrs, int defStyle)][1], but I don't know what to parse in for the second argument. Passing in null results in the View not being displayed [1]: http://developer.android.com/reference/android/view/View.html#View(android.content.Context, android.util.AttributeSet, int)

  • SQL Server 2008 Restore from Backup fails with error 3241 'cannot process this media family'

    - by pearcewg
    I am attempting to backup a database from a SQL Server instance on one machine and restore it to another, and I am encountering the frequently discovered 'SQL Server cannot process this media family' error. Each of my instances are SQL Server 2008, but with different patch levels Restore: 10.0.2531.0 Backup: 10.0.1600.22 ((SQL_PreRelease).080709-1414 ) The restore DB is express. Not sure about the backup version. The backup version is on a virtual private server. The restore is on my development box. When I restore to a different database on the source (backup) server, it restores fine. Lots of stuff on google about this issue, some on stackoverflow about this issue, but nothing which is this exact situation. Any thoughts? It should be straightforward to do a backup and restore from one machine to another (having done this thousands of times in with SQL 6.5,7,2000,2005).

  • DNN redirect Loop

    - by JAllen
    I am trying to duplicate an existing DNN portal that I have for testing purposes by creating a duplicate of the database and duplicating the .net files into a new folder. After I copied the site and changed the webconfig to point to the new site and changed the alias in the database I am getting this error. This webpage has a redirect loop. The webpage at http://xxx.us/xxx/default.aspx has resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer.

  • Naming conventions and field naming question for CakePHP

    - by jphenow
    Okay so two questions very related: 1) Does following the naming convention for classes, controllers, database fields, etc. affect the framework's ability to work the way it was intended? (I'm a little new to working with a framework from the beginning of app development) 2) This question is more important if 1 is a yes. Say I have a table, A, that has 2 foreign keys pointing at the same table, B, but different entries (they're like edges of a graph that point at two vertices) how would I follow the naming convention of their database fields? All I can think to do is something like vertex_1_id and vertex_2_id but I don't know how the framework would handle that if the naming conventions are necessary for its functioning correctly.

  • Yahoo OAuth implementation has no way to work offline

    - by Khash
    I need to download my Delicious bookmarks to a non-web application without constant user interaction. I'm using Delicious's V2 API (using oAuth) but the problem is it seems their access tokens expire after one hour. I don't have any issues with redirecting the user to Yahoo for a one time authorization, but what is described here (http://developer.yahoo.com/oauth/guide/oauth-refreshaccesstoken.html) means I would have to refresh my access tokens all the time before they expire when the user is away. Is this really the way they've done their oAuth implementation?

  • IE8 browser mode vs document mode

    - by mkoryak
    Can someone please explain the difference between IE8 browser mode and document mode in simple terms? What causes the browser mode to change? What causes the document mode to change? If a user changes the mode(s) via developer tools, does the change remain even if the page is refreshed? I am asking this because we are doing some IE8 testing here, and different people have different combinations of the modes, and i want to try to figure out how this is happening.

  • Tactics for using PHP in a high-load site

    - by Ross
    Before you answer this I have never developed anything popular enough to attain high server loads. Treat me as (sigh) an alien that has just landed on the planet, albeit one that knows PHP and a few optimisation techniques. I'm developing a tool in PHP that could attain quite a lot of users, if it works out right. However while I'm fully capable of developing the program I'm pretty much clueless when it comes to making something that can deal with huge traffic. So here's a few questions on it (feel free to turn this question into a resource thread as well). Databases At the moment I plan to use the MySQLi features in PHP5. However how should I setup the databases in relation to users and content? Do I actually need multiple databases? At the moment everything's jumbled into one database - although I've been considering spreading user data to one, actual content to another and finally core site content (template masters etc.) to another. My reasoning behind this is that sending queries to different databases will ease up the load on them as one database = 3 load sources. Also would this still be effective if they were all on the same server? Caching I have a template system that is used to build the pages and swap out variables. Master templates are stored in the database and each time a template is called it's cached copy (a html document) is called. At the moment I have two types of variable in these templates - a static var and a dynamic var. Static vars are usually things like page names, the name of the site - things that don't change often; dynamic vars are things that change on each page load. My question on this: Say I have comments on different articles. Which is a better solution: store the simple comment template and render comments (from a DB call) each time the page is loaded or store a cached copy of the comments page as a html page - each time a comment is added/edited/deleted the page is recached. Finally Does anyone have any tips/pointers for running a high load site on PHP. I'm pretty sure it's a workable language to use - Facebook and Yahoo! give it great precedence - but are there any experiences I should watch out for? Thanks, Ross

  • use of EntityManagerFactory causing duplicate primary key exceptions

    - by bradd
    Hey guys, my goal is create an EntityManager using properties dependent on which database is in use. I've seen something like this done in all my Google searches(I made the code more basic for the purpose of this question): @PersistenceUnit private EntityManagerFactory emf; private EntityManager em; private Properties props; @PostConstruct public void createEntityManager(){ //if oracle set oracle properties else set postgres properties emf = Persistence.createEntityManagerFactory("app-x"); em = emf.createEntityManager(props); } This works and I can load Oracle or Postgres properties successfully and I can Select from either database. HOWEVER, I am running into issues when doing INSERT statements. Whenever an INSERT is done I get a duplicate primary key exception.. every time! Can anyone shed some light on why this may be happening? Thanks -Brad

  • insert a BLOB via a sql script ?

    - by David Michel
    Hi, I have an H2 database (http://www.h2database.com) and I'd like to insert a file into a BLOB field via a plain simple sql script (to populate a test database for instance). I know how to do that via the code but I cannot find how to do the sql script itself. I tried to pass the path , i.e. INSERT INTO mytable (id,name,file) VALUES(1,'file.xml',/my/local/path/file.xml); but this fails. Within the code (java for instance), it's easy to create a File object and pass that in, but directly from a sql script, I'm stuck... Any idea ? David

  • Simple question - XSB Prolog

    - by KP65
    Hello! I'm diving into the world of prolog headfirst but I seem to have hit shallow water! I'm looking at database manipulation in prolog with regards to this tutorial:Learn Prolog Now! It states that I can see my database by entering listing So i tried it and it should basically output everything in my .P file(facts, rules), but this is what i get, here are my sequence of commands: ? consult('D:\Prolog\testfile.P'). [testfile.P loaded] ? listing. library_directory(C:blahblahpathtoXSB) library_directory(C:blahblahXSBpath) {this is listed around 5 times)} shouldn't this command display what is in testfile.P, according to the tutorial? also, after consult testfile.P i should be ableto use assert to add more facts but it doesnt actually change anything in the testfile.P..? any ideas

  • Tridion Installation

    - by Kevin Brydon
    I am currently upgrading an installation of Tridion from 5.3 to 2011 starting almost from scratch (aside from migrating the database), brand new virtual servers. I just want to ask for some advice on my current server setup... a sanity check. All servers are running Windows Server 2008. The pages on our website are all classic ASP. Database SQL Server cluster. The 5.3 database has been migrated using the DatabaseManager. This is pretty standard and works well (in test anyway). Content Manager A single server to run the Content Manager and the Publisher. There are around 10 people using it at any one time so not under a particularly heavy load. Content Data Store Filesystem located somewhere on the network. One directory for live and one for staging. Content Delivery Two servers (cd1 and cd2) each with the the following server roles installed. cd1 writes to a filesystem content data store for the live website, cd2 writes to the content data store for the staging website. Presentation Two public facing web servers (web1 and web2) serving both the live and staging websites. The web servers read directly from the content data store as its a filesystem. Each of the web servers have the Content Delivery Server installed so that I can use dynamic linking (and other features?). I've so far set up everything but the web servers. Any thoughts? edit Thanks to Ram S who linked me to a decent walkthrough, upvoted. I suppose I should have posed some questions as I didn't really ask a question. I guess I'm a little confused over the content deliver aspect. I have the Content Delivery split in two separate parts. cd1 and cd2 do the work of shifting information from the Content Manager to the Staging/Live web directories. web1 and web2 should do the work of serving the web pages to the outside world and will interact with the content data store (file system). Is this a correct setup? I need some parts of the Content Delivery on my web servers right? Theoretically I could get rid of the cd1 and cd2 servers and use web1 and web2 to do the deployment right? But I suspect this will put the web servers under unnecessary strain should there ever be a big publish. I've been reading the 2011 Installation Manual, Content Delivery section, and I'm finding it quite hard to get my head around!

  • Setting The Wallpaper On An IPad

    - by Anirudh
    I think there is no way to set the lock screen wallpaper on the iPhone programmatically (with ref to this question), but with the 3.2 SDK and the ability to set the wallpaper on the home screen on the iPad, does the SDK allow this to be done via APIs now? I looked up the developer reference, but i could not find anything useful.

  • How should one import large amounts of data for FIT/Fitnesse tests?

    - by Lachlan
    We have a scheduling engine with large amounts of test data to test all the scenarios, so test automation is critical. We're currently hoping to use FIT/Fitnesse. However a single test has quite a large table of test data, so it doesn't fit very well into the mould of "two or three inputs, one or more outputs" that Fitnesse uses in its examples. Hopefully the other functionality of Fitnesse makes it worth using it. I hear that there is a way to initialize an application for a FIT test with an Excel spreadsheet - not the Spreadsheet to Fitness function, mind you - but I haven't been able to find it so far. Once the whole spreadsheet is loaded into the application, and the application does its thing, we plan to compare either a number of output rows, or perhaps just the last row, to see if the test passes. The application is currently pulling test data from a database for manual tests, but writing to a database, then initializing from it, is not preferred because of the performance impact. The application is written in C#.
