• What is the best solution to do Reporting on Object data for .NET ?

  - by Peter Fox

  Hi, Our projects are using objects as the data source to reports. Our business layer is returning single objects or IEnumerable. Our reports (quite complex) need to display value-type properties of the object, and its related objects. Typical case would be, from a List, display a master report with category data, then a subreport with data for each Product inside each Category, then a subreport for each Part of each Product, and so on. Reporting from the database is not an option for us. We have tried so far - Reporting Services : works but have to mess around with the XML definition of the report to define the datasource classes, very hard to work with if you use an object datasource, architecturally not too clean - Telerik Reports : quite nice (esp., nice architecture) but seems to have problems with complex reports (master/sub), does not give great paging control, rumored to have performance/crash problems (immature product). Does anyone know a good reporting solution that can be integrated in an ASP.NET application and works well with objects as datasources ?

• Entity framework : [Set all the entities with internal access specifier]

  - by Vedaantees

  Hi, By virtue of my application, I need to seperate my business entities from the entities created by EF4. I need to restrict the entities to only access the repository from where they are translated (using translator) to business entities shared at business and service layer. I thought of restricting them by specifying them as internal. Now there are more than 40 entities in my application so manually setting them as internal is a difficult job. In one of the forums the answers suggested using the T4 templates. But even those templates read from the entity framework access specifier. When I try to manually try to specify all the properties and class access specifiers as internal it gives me an error saying that the entity set should also be set to internal, but there is no option for the same. I am using VS 2010 and Entity Framework 4. Any suggestions???

• Why does dojo parsing time depend on css and images availability?

  - by Kniganapolke

  I have been profiling javascript on my page that uses dojo widgets. I don't use explicit parsing - the parser runs on page load. What I noticed is that if I clear browser cache before refreshing the page, dojo parsing takes much more time than if all the files are already cached. Note that we build all the required dojo modules into a layer (a single file), so we don't lazy-load any js files. I wonder if dojo parsing process depends on images and css resources, as far as I know it only instantiates widgets and injects dom nodes. Do you have any ideas why dojo parser runs longer (2-3 times longer in my case) when the cache is cleared?

• Need help in understanding the mapping of user-space send, sendto, sendmsg to kernel-space sendmsg

  - by bala1486

  Hello, I am trying to implement my own transport layer protocol in Linux for an experiment. I am going to use socket interface and add my protocol using sock_register. For the proto_ops i can see that the parameters for the sendmsg and recvmsg are (struct kiocb *iocb, struct socket *sock, struct msghdr *msg, size_t len, int flags). But there are three types of user api's send, sendto, sendmsg. Of these three only sendmsg contains a parameter for msghdr. I find that the other two api's are incompatible with the parameters supplied by the kernel to my kernel-space sendmsg function. So what happens when we use send and sendto user-space api's? Hope i am clear.. Thanks, Bala

• WinForm - WPF integration; Piece by Piece

  - by Refracted Paladin

  I have a medium sized WinForm App (1 Form that hosts 40 user controls) that we use in house. I want to migrate over to WPF but I cannot do a Mass ReRelease. My idea was, for now, to recreate the App 1 User Control at a time in WPF and have that hosted in the existing WinForm App. I would make them look nearly identical, at this point, so there would be no need for mass retraining. My question is more to the point of, has any one else tried this and how does the data portion work. I have recreated one of the WinForms User Controls as a WPF user Control. Do I need to publish that as a User Control Library? How, then, would I access the DAL for that UC? I use a Linq to Sql data layer.

• Best architecture for accessing secondary database

  - by fearofawhackplanet

  I'm currently developing an app which will use a Linq to SQL (or possibly EF) data access layer. We already have a database which holds all our Contacts information, but there is currently no API around this. I need to interact with this DB from the new app to retrieve contact details. I can think of two ways I could do this - 1) Develop a suite of web services against the contacts database 2) Write a Linq to SQL (or EF) DAL and API against the contacts database I will probably be developing several further apps in the future which will also need access to the Contacts data. Which would generally be the prefered method? What are the points I need to consider? Am I even asking a sensible question, or am I missing something obvious?

• Entity Framework VS LINQ to SQL VS ADO.NET with stored procedures?

  - by BritishDeveloper

  How would you rate each of them in terms of: Performance Speed of development Neat, intuitive, maintainable code Flexibility Overall I like my SQL and so have always been a die-hard fan of ADO.NET and stored procedures but I recently had a play with Linq to SQL and was blown away by how quickly I was writing out my DataAccess layer and have decided to spend some time really understanding either Linq to SQL or EF... or neither? I just want to check, that there isn't a great flaw in any of these technologies that would render my research time useless. E.g. performance is terrible, it's cool for simple apps but can only take you so far

• Drupal - Counting data in nodes, creating custom statistics

  - by hfidgen

  Hiya, I'm building some custom content types to capture customer data on a website. Admins will enter the data, users will be able to view it, but I also need to be able to bolt on some statistics and infographics to the data. The problem I have is that I can't see any simple way of doing this within Drupal. Are there modules which can produce simple stats on selected node types or will I have to write a complete custom module using the data abstraction layer? Thanks for any insights!

• animate rotation

  - by Mike

  I'm trying to animate a rotation using CATransform3DMakeRotation, but the problem is once the animation is finished, the image goes back to its initial position, i.e back to zero. But I'd like to keep it where it finished rotating. How would I do that? edit What I'm trying to do is to create the same compass which comes with the new iPhone. Basically the locationmanager gives me new headings every few seconds (or several per second). Using the new heading and the timestamp, I was trying to get a smooth animation of the image but not getting anywhere. The only thing which seems to work is applying the transform directly, e.g. compassimage.layer.transform = CATransform3DMakeRotation(newHeading.trueHeading *M_PI/180,0,0,1.0): but that's not animated...

• What happened to the Windows "Midi Mapper"

  - by interstar

  I wrote a windows program many years ago, which created music by sending notes to the "midi mapper" (and thence to the midi-synth on my sound-card) Today, I have a soft-synth which, allegedly accepts midi information, so I'd assume it should be possible to use today's equivalent of a midi-mapper to route the midi output from my program to the soft-synth. There's clearly no longer a midi-mapper application in windows, but my program still works (on XP) in that it drives the built-in soundcard synth, so there must be some sort of midi handling layer in windows. How can I get at this? And maybe redirect the midi to the soft-synth?

• Is it a good idea to "migrate business logic code into our domain model"?

  - by Bytecode Ninja

  I am reading Hibernate in Action and the author suggests to move business logic into our domain models (p. 306). For instance, in the example presented by the book, we have three entities named Item, Bid, and User and the author suggests to add a placeBid(User bidder, BigDecimal amount) method to the Item class. Considering that usually we have a distinct layer for business logic (e.g. Manager or Service classes in Spring) that among other things control transactions, etc. is this really a good advice? Isn't it better not to add business logic methods to our entities? Thanks in advance.

• Redirect application's graphical output in Windows Vista/7 (with DWM)

  - by puri

  I want to create a desktop manager that takes informations of all running applications including states and screenshots to display and manipulate them in my virtual space (probably in 3D). It can be considered as another layer of abstraction on top of Windows itself. Because many native Windows Vista/7 features like Flip 3D and Live Thumbnails are able to show each window's activities in real-time e.g. video keeps playing in taskbar's thumbnail, I think DWM allows an application to redirect its output to somewhere else or some special processes are able to collect other applications' graphical outputs (maybe of child processes only). Has Microsoft released a set of public APIs to do so? If not, is it technically possible? And is it easier if I limit my scope to just .NET applications with WPF?

• DataReader Behaviour With SQL Server Locking

  - by Graham

  We are having some issues with our data layer when large datasets are returned from a SQL server query via a DataReader. As we use the DataReader to populate business objects and serialize them back to the client, the fetch can take several minutes (we are showing progress to the user :-)), but we've found that there's some pretty hard-core locking going on on the affected tables which is causing other updates to be blocked. So I guess my slightly naive question is, at what point are the locks which are taken out as a result of executing the query actually relinquished? We seem to be finding that the locks are remaining until the last row of the DataReader has been processed and the DataReader is actually closed - does that seem correct? A quick 101 on how the DataReader works behind the scenes would be great as I've struggled to find any decent information on it. I should say that I realise the locking issues are the main concern but I'm just concerned with the behaviour of the DataReader here.

• Disable animation when moving CALayers

  - by Sean Clark Hess

  The following code animates the movement, even though I didn't use beginAnimations:context. How do I get it to move without animating? This is a new iphone view project, and these are the only updates to it. // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; sublayer = [CALayer new]; sublayer.backgroundColor = [[UIColor redColor] CGColor]; sublayer.frame = CGRectMake(0, 0, 100, 100); [self.view.layer addSublayer:sublayer]; } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { sublayer.position = [[touches anyObject] locationInView:self.view]; }

• How to overwrite specific lines on text files

  - by iTayb

  I have two text files. I'd like to copy a specific part in the first text file and replace it with a part of the second text file. This is how I read the files: List<string> PrevEp = File.ReadAllLines(string.Format(@"{0}naruto{1}.ass", url, PrevEpNum)).ToList(); List<string> Ep = File.ReadAllLines(string.Format(@"{0}naruto{1}.ass", url, EpNum)).ToList(); The part in PrevEp that I need: from the start until it meets a line that includes Creditw,,0000,0000,0000. The part I would like to overwrite in Ep: from the start to a line which is exactly Format: Layer, Start, End, Style, Name, MarginL, MarginR, MarginV, Effect, Text. I'm not so sure how may I do it. Could you lend me a hand? Thank you very much, gentlemen.

• Best implementation for MySQL replication with Rails 3?

  - by vonconrad

  We're looking at potentially setting up replication for our primary MySQL database, and while setting up the replication seems pretty straight-forward, the application implementation seems a bit murkier. My first idea would be to set up a master-slave configuration and RW-splitting, with all write queries (CREATE, INSERT, UPDATE) going to master, and all read queries (SELECT) going to slave. Having read up on it, it seems that there are essentially two options for how to implement this with our app: Using an independent middleware layer for all MySQL connections, such as MySQL proxy or DBSlayer. However, the former is in Alpha and the latter has limited documentation. Using a Ruby-based gem/plugin, such as Octopus to achieve RW-splitting in the framework. If we wanted to go with a master-slave setup, what you recommend moving forward? The other thought I've had was to use a master-master configuration, but am unsure about the implementation of such a setup. Thoughts?

• Hibernate or JPA or JDBC or ???

  - by Yatendra Goel

  I am developing a Java Desktop Application but have some confusions in choosing a technology for my persistence layer. Till now, I have been using JDBC for DB operations. Now, Recently I learnt Hibernate and JPA but still I am a novice on these technologies. Now my question is What to use for my Java Desktop Application from the following? JPA Hibernate JDBC DAO any other suggestion from you... I know that there is no best choice from them and it totally depends on the complexity and the requeirements of the project so below are the requirements of my project It's not a complex application. It contains only 5 tables (and 5 entities) I wan't to make my code flexible so that I can change the database later easily The size of the application should remain as small as possible as I will have to distribute it to my clients through internet. It must be free to use in commercial development and distribution.

• SubSonic 3.0 - Save method with all columns as parameters?

  - by Todd Menier

  Hi, Just getting started with SubSonic. I'm using the Repository pattern, so my domain objects are totally seperate, and SubSonic-generated classes are used only in my data access layer. I'm wondering if a template exists that will give me a Save method (Insert/Update) that requires all table column values as parameters. My thinking is that since I need to do the mapping work manually, at least if my database schema changes (ie, a new column is added), I won't forget to add a corresponding mapping, since the auto-generated method signature would change and the compiler would catch it. I've considered messing with the T4 templates to add this feature, but thought I'd check if this already exists somewhere before I head down that path. Thanks in advance.

• Does Ruby on Rails "has_many" array provide data on a "need to know" basis?

  - by Jian Lin

  On Ruby on Rails, say, if the Actor model object is Tom Hanks, and the "has_many" fans is 20,000 Fan objects, then actor.fans gives an Array with 20,000 elements. Probably, the elements are not pre-populated with values? Otherwise, getting each Actor object from the DB can be extremely time consuming. So it is on a "need to know" basis? So does it pull data when I access actor.fans[500], and pull data when I access actor.fans[0]? If it jumps from each record to record, then it won't be able to optimize performance by doing sequential read, which can be faster on the hard disk because those records could be in the nearby sector / platter layer -- for example, if the program touches 2 random elements, then it will be faster just to read those 2 records, but what if it touches all elements in random order, then it may be faster just to read all records in a sequential way, and then process the random elements. But how will RoR know whether I am doing only a few random elements or all elements in random?

• How can one make a web-site accessible only when someone has a dongle?

  - by Brian M. Hunt

  Suppose you want to add an extra layer of credentials on top of a SSL-encrypted login/password, but you don't want to increase complexity to the user. Is there a way to add the requirement of the possession of a dongle to web-server authentication schemes with existing cross-platform browser capabilities? In other words, to get access to the web-site, you would need a username, password, and a USB dongle that has been plugged into the client computer. The dongle would presumably do some sort of challenge/response. It'd be ideal if this dongle solution worked with Firefox automatically or with the simple addition of a plugin. Thoughts and suggestions are appreciated.

• What are the main benefits of implementing a virtual machine as part of an application?

  - by Marplesoft

  Several databases I've been looking at recently implement a virtual machine internally to perform the respective data reads and writes. For an example, check out this article on SQLite's virtual machine they call the 'VDBE'. I'm curious as to what the benefits of such an architecture are. I would assume performance is one but why would a virtual machine like this run faster? In fact, it seems to be that this extra layer could cause it to run slower. So perhaps it's for security? Or portability? Anyway, just curious about this.

• iphone/ipad application - taking screen shot

  - by satyam

  I successfully implemented an application that works on ipad as well as on iphone. In that I provided option to user to send the screen shot of the application as mail attachment. Even that is functioning well. But my code is taking screen shot irrespective of orientation. The image i'm getting is always in portrait mode. I want to take the screen shot depending on the orientation of ipad/iphone and send the image as attachment. I'm using following code to take the screen shot. UIGraphicsBeginImageContext(screenWindow.frame.size); [screenWindow.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *screenshot = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext();
