• Infopath - changing sql servers

  - by ScottStonehouse

  I have an InfoPath form which has sort of a master-detail pattern, with two tables in the underlying main datasource. I am trying to migrate this to a new SQL Server - same database, just moved from a SQL2005 machine to a SQL2008 machine. If I change the servername, it also wants me to change the database and tables. If I select the same database and master table, the bindings are maintains for the master table. But there doesn't appear to be a way to select multiple tables when you change the datasource, so you lose the detail bindings. Am I missing something - I'm pretty new to InfoPath.

• Managing SQL Server users via Active directory groups

  - by hyty

  I'm building SQL Server instance for reporting purposes. My plan is to use AD groups for server and database logins. I have several groups with different roles (admin, developer, user etc.), and I would like to map these roles into SQL Server database roles (db_owner, db_datawriter etc.). What are the pros and cons of using AD groups for logins? What kind of problems you have noticed?

• Snow Leopard not reading NTFS

  - by dtmunir

  I just upgraded a brand new Macbook Pro that I bought with 10.5 installed to Snow Leopard. After doing the upgrade I am trying to access NTFS partitions on my external hard drive but they are just not showing up. I went ahead and installed Windows 7 using Parallels, and I can access the NTFS partitions from within Windows, but not from Mac OS X. I know that Snow Leopard should be able to at least read NTFS drives, so what is going on here?

• using nested arrays by php http_build_query() and recieve them in flash AS3

  - by Mahmoud

  hi, i am having this hard time figuring what is needed to do, i am using URLVariables to send/recieve values between flash and PHP the problem is, i am unable to access nested arrays ( array inside an array ) with flash heres an example: $dgresult = array("total" = $results); echo http_build_query($dgresult,"flf_"); in flash, all i need to do is to use: var variables:URLVariables = new URLVariables(e.target.data); then i can access it with : variables.total the problem now is when i have nested arrays: $dgresult = array("total" = $results); array_push($dgresult,$another_array); http_build_query($dgresult,"flf_"); i can still access variables.total but what about anything that has flf_ ? how is that possible?

• Running Sybase ISQL scripts from windows batch file

  - by user1328709

  I have already researched on this site as well as on google extensively for this. I have created a number of batch files that perform certain automated transactions(backups etc) on our production database. i want to further simplify my end of day processes by taking the dumps using a script that accepts input of some parameters. the script is able to login the isql prompt but unable to do the execution of the commands. @ECHO ***Started*** @ECHO Enter MonthDay(MMDD) SET /p md= @ECHO %md% mkdir \\10.20.1.17\arch\212%md%_banking set run=isql -Uuser -SORBITS -Ppass %run% @echo dump database banking to '/media/newArch/212%md%_banking/212%md%EOD_banking.dmp' with compression=5 @echo dump database master to '/media/newArch/212%md%_banking/212%md%EOD_master.dmp' @echo go pause I have been unsuccessful at putting these in a separate script file because the script itself uses a passed parameter. Please give me hints and links to Thanks

• 2 large databases - worth merging into 1?

  - by Ardman

  I have 2 large databases that were sharded before. I now have removed the sharding and have created a new database with all of the data except for the tables that were originally sharded. Is it worth importing this data into the new database, or keeping them as seperate entities that I can just scan through? We are talking around 60million records in each sharded table, of which there are 2 tables. Also, whilst I have an empty table, should I be adding indexes which weren't thought of when the database was originally constructed and now too large to add them?

  - by Jack Marchetti

  Here's my query. var query = from g in dc.Group join gm in dc.GroupMembers on g.ID equals gm.GroupID where gm.UserID == UserID select new { id = g.ID, name = g.Name, pools = (from pool in g.Pool // more stuff to populate pools So I have to perform some filtering, but when I attempt to filter var filter = query.Where(f => f.pools.[no access to list of columns] I can't access any of the items within "pools".

What I'd like to do is this: var filterbyGame = query.Where(f = > f.pools.GameName == "TestGame"); Let me know if that's even possible with thew ay I have this setup. Thanks guys.

• Strange behaviour of code inside TransactionScope?

  - by Krishna

  We are facing a very complex issue in our production application. We have a WCF method which creates a complex Entity in the database with all its relation. public void InsertEntity(Entity entity) { using(TransactionScope scope = new TransactionScope()) { EntityDao.Create(entity); } } EntityDao.Create(entity) method is very complex and has huge pieces of logic. During the entire process of creation it creates several child entities and also have several queries to database. During the entire WCF request of entity creation usually Connection is maintained in a ThreadStatic variable and reused by the DAOs. Although some of the queries in DAO described in step 2 uses a new connection and closes it after use. Overall we have seen that the above process behaviour is erratic. Some of the queries in the inner DAO does not even return actual data from the database? The same query when run to the actaul data store gives correct result. What can be possible reason of this behaviour?

• Hashes vs Numeric id's

  - by Karan Bhangui

  When creating a web application that some how displays the display of a unique identifier for a recurring entity (videos on YouTube, or book section on a site like mine), would it be better to use a uniform length identifier like a hash or the unique key of the item in the database (1, 2, 3, etc). Besides revealing a little, what I think is immaterial, information about the internals of your app, why would using a hash be better than just using the unique id? In short: Which is better to use as a publicly displayed unique identifier - a hash value, or a unique key from the database? Edit: I'm opening up this question again because Dmitriy brought up the good point of not tying down the naming to db specific property. Will this sort of tie down prevent me from optimizing/normalizing the database in the future? The platform uses php/python with ISAM /w MySQL.

• SQL Azure and VS 2010B2 or SSMSE 2008

  - by Vulgrin

  Ok, I see that people have asked this question before, but I'm seeing some conflicting statements. Can I, or can I not, connect directly to my SQL Azure database from SSMSE 2008? I see posts from before November that the SSMS 2008 RC would be able to connect directly - so I don't understand why the newest SSMSE cannot connect. Is it just a problem with the Express version of SSMS? Where can I find the "non-Express" version, if there is one? I can connect to the database via the cancel and connect method - however, you don't get object explorer that way. I see that there are add-ons for VS.Net to allow you to explore the database but I wanted to do it with the base apps if possible. Thanks

• How far does Dependency Injection reach?

  - by Baddie

  My web app solution consists of 3 projects: Web App (ASP.NET MVC) Business Logic Layer (Class Library) Database Layer (Entity Framework) I want to use Ninject to manage the lifetime of the DataContext generated by the Entity Framework in the Database Layer. The Business Logic layer consists of classes which reference repositories (located in the database layer) and my ASP.NET MVC app references the business logic layer's service classes to run code. Each repository creates an instance of the MyDataContext object from the Entity Framework Repository public class MyRepository { private MyDataContext db; public MyRepository { this.db = new MyDataContext(); } // methods } Business Logic Classes public class BizLogicClass { private MyRepository repos; public MyRepository { this.repos = new MyRepository(); } // do stuff with the repos } Will Ninject handle the lifetime of MyDataContext despite the lengthy dependency chain from the Web App to the Data Layer?

• Passing data with Rails' link_to helper

  - by mathee

  I am implementing a question-and-answer application with Ruby on Rails. I have MVCs for Questions and Answers. In the home view (index.haml), I list the Questions like this: - @questions.each do |q| %tr %td =link_to q.title, q Next to each of those, I want to add a link that will create a new Answer and pass the id of the Question in that row (continued from the above Haml code) : %td #{link_to 'answer me!', new_answer_path, pass q.id here somehow?} I don't know how to properly pass it and then access it in AnswersController. I tried #{link_to 'answer me!', new_answer_path, :question_id => q.id}, but that was just a guess, and I don't know how to access that in AnswersController. I read the Rails API docs, and I know you can add query, too, but I still don't know how to access the value in AnswersController.

• UnauthorizedAccessException cannot resolve Directory.GetFiles failure

  - by Ric Coles

  Hi all, Directory.GetFiles method fails on the first encounter with a folder it has no access rights to. The method throws an UnauthorizedAccessException (which can be caught) but by the time this is done, the method has already failed/terminated. The code I am using is listed below: try { // looks in stated directory and returns the path of all files found getFiles = Directory.GetFiles(@directoryToSearch, filetype, SearchOption.AllDirectories); } catch (UnauthorizedAccessException) { } As far as I am aware, there is no way to check beforehand whether a certain folder has access rights defined. In my example, I'm searching on a disk across a network and when I come across a root access only folder, my program fails. I have searched for a few days now for any sort of resolve, but this problem doesn't seem to be very prevalent on here or Google. I look forward to any suggestions you may have, Regards

• Dealing with XML in ASP.NET MVC

  - by Matt W

  I have a block of XML in a database which is easy enough to pull out using ASP.NET MVC, however I would like to access and modify the XML in an way more consistent with class instances. Is there a way to get the MVC (or any other model) to generate a data access (or perhaps Entity) class set from the DB-stored XML? If the above is rather obtuse, the question could be summarised as; What method would you use to best access and modify XML stored in a database from an ASP.NET MVC application? Thanks, Matt.

• Why does headless PDE Build omit directories I've specified in build.properties's bin.includes?

  - by Woody Zenfell III

  One of my Eclipse plug-ins (OSGi bundles) is supposed to contain a directory (Database Elements) of .sql files. My build.properties shows: bin.includes = META-INF/,\ .,\ Database Elements/ (...which looks right to me.) When I build and run from within my interactive Eclipse IDE, everything works fine: calls to Bundle.getEntry(String) and Bundle.findEntries(String, String, bool) return valid URL objects; my tests are happy; my code is happy. When I build via headless ant script (using PDE Build), those same calls end up returning null. My tests break; my code breaks. I find that Database Elements is quietly but simply missing from my plug-in's JAR package. (META-INF and the built classes still make it in there fine.) I scoured the build log (even eventually invoking ant -verbose on the relevant portion of the build script) but saw no mention of anything helpful. What gives?

• Amazon AWS s3fs mount problem on Fedora 14

  - by Alex

  I successfully compiled and installed s3fs (http://code.google.com/p/s3fs/) on my Fedora 14 machine. I included the password credentials in /etc/ as specified in the guide. When I run: sudo /usr/bin/s3fs bucket_name /mnt/bucket_name/ it runs successfully. (note: the bucket name is the same as the folder name in /mnt/). When I run ls in /mnt/ I get the error "ls: cannot access bucket_name: Permission denied". When I run sudo chmod 640 /mnt/bucket_name I get "chmod: changing permissions of `bucket_name': Input/output error". When I reboot the machine I can access the folder /mnt/bucket_name normally but it is not mapped to the s3 bucket. So, basically I have two questions. 1) How do I access the folder (/mnt/bucket_name) as usual after I mount it to the s3 bucket and 2) How can I keep it mounted even after machine restart. Regards

• How can I stop sorl thumbnail from breaking with very long filenames?

  - by bitbutter

  I've noticed that when working with SORL thumbnail, sometimes a user will upload an image with a very long filename, longer than the varfield in the database can hold. The name gets truncated in the database and the project gives errors whenever the image is requested. Is there a smart and safe way to have django automatically truncate long filenames in sorl uploads (prior to saving them in the database) to prevent this sort of thing? As reference, here's how the relevant model from my current project looks: class ArtistImage(models.Model): artist = models.ForeignKey(Artist) position = models.IntegerField() image = ThumbnailField( thumbnail_tag='<span class="artistimagewrapper"><img class="artistimage" src="%(src)s" width="%(width)s" height="%(height)s"></span>', upload_to='uploaded_images/artistimages', size=(900,900), quality=100, options={'crop': 'center'}, extra_thumbnails={ 'small':{ 'size':(92,92), 'quality':100, 'options':{'crop': 'center'}, } } ) class Meta: ordering = ('image',) def __unicode__(self): return (u"%s" % self.image)
