  • Incorrect syntax near ''. Unclosed quotation mark after the character string ' '.

    - by Mattec
    I'm just wondering if someone could point me in the right direction here, I think i've been looking at it for too long so can't see the mistake. The following code: SqlCommand updateStyle = new SqlCommand("UPDATE [Lorenz].[dbo].[Layout] SET [bgColour] = '" + bgColour + "' , [textColour] = '" + txtColour + "WHERE <[LoweredUserName] ='" + currentUser + "' ", connection); updateStyle.ExecuteNonQuery(); Is giving the error: Incorrect syntax near 'admin'. Unclosed quotation mark after the character string ' '.

  • Castle ActiveRecord optimistic locking on properties

    - by Daniel T.
    Can Castle ActiveRecord do optimistic locking on properties? I found optimistic locking for the entire class, but not for an individual property. In my case, I need to make it so that adding/removing elements in a collection does not update the version number of the entity (so for example, adding a Product to a Store without changing any of Store's properties will not increment the version number).

  • How convert a string into a ActiveSupport::TimeWithZone?

    - by Nisanio
    How convert a string into a ActiveSupport::TimeWithZone? My dilemma is this. I need to update a field (called updated_at). The field in mysql is datetime, and the class is ActiveSupport::TimeWithZone. But the dates are strings like "10/17/2008". I used "10/17/2008".to_date (And I intend .to_time and to_datetime), and even if in console the ActiveRecord class save succesfully, the field in the database still is the current date... Thanks in advanced.

    - by andrecarlucci
    Hello, The problem started after installing RiaServices Toolkit Dec 2010. If I unload the project and reload it again, I get this message, even on an empty Silverlight project (no changes made to the project file). "error : A project with that name is already opened in the solution." The solution has only 2 projects: the host (web) and the silverlight one. Any help is appreciated :) UPDATE: It only happens if I give the Silverlight project the same name as the solution.

  • How do I use SVN effectively?

    - by Tim Rogers
    I have an SVN repository that I've set up on my VPS, and I know all the basics (update, commit), but I don't know what all the other options mean. I am running TortoiseSVN on Windows (which is great!) and can see all these features like branching, locking, merging and patching! What do all these things mean? Is there anywhere with a good guide about how all the little bits and pieces in SVN work? Thanks, Tim

  • Offline backup synchronization

    - by Pavan Kumar
    There is a Central Server running Windows Server 2003 and SQL Server 2005 and there are 7 client machines situated in various places and has XP Pro & SQL Server 2005 installed in all of them. They are not interconnected so they are physically seperate. One person goes to each of these centers maybe twice a month and takes the backup (Full database consisting of mdf and ldf files) with a pen drive and brings it to the Central server which contains the central database holding same schema as all the other client databases. I need to synchronize each backup database (belonging to different centers) one by one to update the existing data or inserting new data in the central database . The solution i got was Replication. The pendrive is brought to central server consisting of 7 instances of the databases and then the databases is attached to the central server one by one to the same SQL Server where the central database exists. Then my idea was to replicate the backup database one by one i.e using single subscription (Central Database) and multiple publication ( i.e 7 instances of databases in my case) toplogy by performing replication locally (i.e in the same machine). So i tried to develop a UI in C# .Net to programatically run the Transactional Replication with push subscription using RMO Programming (which is incomplete as of now because there is no point in developing when you already know it is not the solution). Transactional Replication can either be set to initialize with a snapshot or without a snapshot. If i go for the first option i.e with a snapshot , the data whatever is present in Central Database is overwritten by the new data . So the data present initially in the central database is lost. If i try to initialize without snapshot , no data (the data already has the updated and new data) will be sent from the backup database to server. The replication will work in a scenario where any incremental changes is done only after you set the replication . So the initial data whatever was present in the backup database when setting up the replication will not be replicated when running the snapshot agent for the first time to synchronize. Only changes in the backup database thereafter will be reflected to the central database .(Remember I am not going to insert new data or make any changes to the backup database after i attach it to the Central Server. ) So this solution is not feasible. I want a solution for synchronizing from one client database to central database present in the same machine using C#.NET. If you can provide me small example maybe with two databases(with same schema) DB1(Client) to DB2(Server) consisting of one or two tables it will be very helpful. The synchronization is not bidirectional.I want to only update existing data or insert new data from DB1 to DB2 (DB2 may contain some data initially). Thanks and Regards Pavan

  • What is the best way to document a system metaphor?

    - by SDReyes
    A metaphor help us to communicate with our project stakeholders, using a shared set of concepts and analogies. we develop them all the time, in one way or another. even the XP- programming highly recommend to get it defined since project start. How do you write such thing down in a document (specially if it already exists)? maybe a dictionary-like approach? UPDATE: perhaps a thesaurus would do it better (synonyms sum).

  • Suggest the best options to me to design the dynamic web interface using PHP MYSQL and AJAX

    - by Krishna
    Hello, I am designing a web interface for a company. I am describing the company's profile: company is currently having 5 branches and planning to extend their branches all over the country. it is an insurance surveying company. they are dealing with 6 Categories in the insurance domain, vide .. Engineering Fire Marine Motor Miscellaneous Risk Inspection and branches named as b1, b2, b3, b4, b5 and Extending. and finally they have contract with 22 companies. For each claim they are assign a unique ID. like contractcompany/category/serialno Ex: take a contracted company names as xxx, sss, zzz. xxx/Engineering/001 sss/Engineering/001 . . . xxx/Enginnering/002 sss/Engineering/002 . . . xxx/Fire/001 sss/Fire/001 . . . xxx/Fire/002 . . . xxx/Fire/002 . . . and so on..... by this way they issue the unique ID for each claim. Finally what i want is developing the interface with PHP mysql and ajax auto generating the unique id for each claim. store full details of the claims with reference to unique id. show all claims in one page, and they can view by branch wise and category wise. send monthly Report (All claims they have given and status of claims) to contract companies. give access to contracted companies, but they can view only their respective claims. Each claim has its own documents. So they can be uploaded by own company users or administrator. these files are associated with unique ID. contracted companies can view files. Give access to branches to enter new claims and update old claims. Administrator can create, update and delete all the claims and their details. Only administrator can grant new users (own company branches / contracted companies) Finally the the panel is completely database driven. Could any body can help. Thanks in advance Kindly do the needful and oblige Thanks and Regards Krishna. P [email protected]
