  • 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 ?

  • Is SQL server the best DB for Storing and comparing images in database for a small ecommerce applica

    - by iecut
    I have been trying to create a small e-commerce web based application using MS Dot Net framework. The application will let the user allow to store the image of their product that they want to sell or purchase, then they will have the option to upload the image of a particular product and compare that image with the similar images in the database. So my two main concerns are: - Is MS SQL a good option to store and compare the images. - Is the any other better database that can do the same work with less complexity of work and that is also easy to integrate with MS dot net framework.

  • What is the return type for a anonymous linq query select? What is the best way to send this data ba

    - by punkouter
    This is a basic question. I have the basic SL4/RIA project set up and I want to create a new method in the domain service and return some data from it. I am unsure the proper easiest way to do this.. Should I wrap it up in a ToList()? I am unclear how to handle this anonymous type that was create.. what is the easiest way to return this data? public IQueryable<ApplicationLog> GetApplicationLogsGrouped() { var x = from c in ObjectContext.ApplicationLogs let dt = c.LogDate group c by new { y = dt.Value.Year, m = dt.Value.Month, d = dt.Value.Day } into mygroup select new { aaa = mygroup.Key, ProductCount = mygroup.Count() }; return x; // return this.ObjectContext.ApplicationLogs.Where(r => r.ApplicationID < 50); } Cannot implicitly convert type 'System.Linq.IQueryable<AnonymousType#1>' to 'System.Linq.IQueryable<CapRep4.Web.ApplicationLog>'. An explicit conversion exists (are you missing a cast?) 58 20 CapRep4.Web

  • How to best deal with photos passed to IFilter?

    - by sharptooth
    I'm implementing an IFilter for indexing image formats. One problem is photos - many users have tons of photos, photos are huge and loading and searching for text on them is time consuming. Yes, sometimes people use cameras instead of scanners for digitizing documents, but the potential problems IMO far outweight the possibility of encountering a document digitized with a photo camera. So my implementation will not extract text from photos at all. What should the IFilter do once it detects that a given file is a photo image - indicate an error or return empty text?

  • What's the best way to access Neo4j from Django?

    - by abdel
    it seems that i found something that let me confused; i've found two Neo4j to download to python, the first one is: http://pypi.python.org/pypi/neo4j-embedded and the second one is: https://svn.neo4j.org/components/neo4j.py/trunk/ what's the difference between the two? the first one seems to be big (size), so does this mean that if i use it i'll not need the neo4j community release (milestone)? when i've installed the first one, and tried to test a django example, it seems that the directory named "model" https://svn.neo4j.org/components/neo4j.py/trunk/src/main/python/neo4j/model/ is missing? so what's the difference, and who will be better to use with Django? and what about that one? http://pypi.python.org/pypi/neo4django/

  • What .NET reporting tools are best for dynamic report generation?

    - by bvanderw
    Perhaps I need to define "dynamic generation". By this I mean using graphics primitives to draw on the page (such as DrawText or DrawLine, etc) This is what System.Drawing.Printing provides. I often need to create forms and reports for Windows applications that either require dynamic generation or where I need control over the formatting that stretches or goes beyond the capabilities of most report designers. Essentially, I need to ability to create my own pages using graphics primitives like you can do with System.Drawing.Printing that are part of package that also provides a report designer, exporting to PDF, etc. In my Delphi days, I used Rave Reports (along with the exporting add-ons from Gnostice) because it was the only Delphi reporting tool that gave you that kind of fine control. I've been struggling with the reporting tools provided by Developer Express and I have given up trying to make them do what I need to do. I downloaded a trial of ActiveReports and was able to completely create one of my dynamic reports (using their Page class) in a few hours one afternoon. It's likely I will buy their product, but it's a bit frustrating to have to do so after investing in the Developer Express tools. Before I do so, are there any other products that offer this functionality that I should investigate? As far as I can tell, Crystal Reports does not - is this correct? Thanks.... --Bruce

  • Which sector in IT industry best suites my career needs?

    - by Shailesh Tainwala
    I am a student of software engineering and will be graduating in a years time. I want to get a few years of work experience before considering further studies. I like the idea of working on projects developing end-to-end systems for medium/large enterprises in different domains. My area of special interest is AI and data-mining.

  • What is the best IDE to use with the Symfony framework?

    - by Failpunk
    I'm looking for an IDE with use with the Symfony Framework. I have a bit of experience using the NetBeans 6.5 IDE but it does not always seem to complete the class methods, plus it doesn't seem to have any PHP code snippets built in. Here are the features I would ideally like to have, in order of importance, from an IDE: Code completion of all the Symfony and Propel class methods (I can never remember them) Code templates,(class skeletons, HTML structures, Symfony templates?) Straight-forward code debugging Source Control

  • How to best future proof my application that needs to connect to Outlook?

    - by Troy
    I have a contact management application written in Delphi which has a “Sync with Outlook” feature that I developed 10 years ago. Now, I’m going back to add some features and fix some bugs. This sync feature uses the Outlook object model to get started, but it has an optional mode called “Use MAPI Enhancements” where it uses pure MAPI to speed up how it looks for changes, and it allows notes to be synced w/ RTF instead of just plain text. I'm wondering if supporting two parallel paths of execution is a good idea or not. If I went with all MAPI, I believe I'd avoid some security prompts, and I'd avoid situations where anti-virus has "script-blocking" features which block my app from connecting to Outlook. But I believe that on the down side, my 32-bit app would not be able to to connect with 64-bit Outlook 2010 using MAPI. And I wonder about the future of MAPI in general. If I stick with the Outlook object model, will my 32-bit app be able to connect to the Outlook object model (since it's out of process COM)? If so, this is a compelling reason to keep my Outlook object model execution path in place. But if not, and if my app needs to be compiled for x64, then why not just go with pure MAPI?

  • How do I best implement my Windows desktop and service C# applications automatic updates?

    - by Ivan
    My project contains WinForms, WPF, and Windows Service programs running on users' office desktop PCs. I want these applications to periodically check for new versions available at specific URL, automatically download new versions and replace themselves with new versions without attracting any user attention (keeping in mind that users may run Windows from XP to 7 and work using non-privileged account (which can be part of active directory)). Alternatively the whole update package has to be able to be distributed as an unattended-installed MSI package. Any recommendations on implementing this?

  • What's the best way to tell if the mouse is over a form or not?

    - by cyclotis04
    I figured out how to capture mouse clicks over the entire form, but this method doesn't translate well for MouseEnter and MouseLeave. My form layout is made up from many Panels and TableLayoutPanels so there's no all-encompassing control I can monitor events for, and obviously a MouseLeave event for a button doesn't mean the cursor left the entire form. Has anyone figured out a good way to get around this?

  • Best way to implement refusing a value change by the user in Swing?

    - by Michael Borgwardt
    I have a JCheckBox that should not be checked by the user when a certain other field is empty. So now I want to have an error popup and then reset the checkbox (I've considered disabling the checkbox, but the connection to the other field is non-obvious, and a tooltip text IMO not visible enough). What's the correct way to do that in Swing? Through a PropertyVetoException? Where do I throw it and where do I catch it? My first (probably ugly) idea would be to add a ChangeListener that itself shows the popup and resets the value.

  • What is the best logging solution for a C# .NET 3.5 project?

    - by Odd
    My team is about to start a new enterprise wide ASP.NET development project, quite possibly the largest undertaken by my department so far and the largest project that I've ever worked on. I'm looking for a good logging solution for the system. Firstly, what logging tools are currently available and widely used? Secondly, for an ASP.NET (probably MVC) enterprise applicaiton, which tool is most appropriate based on your experience? So far I've used Log4net almost exclusively for all my previous projects. It's a fantastic tool, however I would like to see if there is anything I've not used out there before I start a project of this magnitude or if there is any reason I would not want to use Log4net for a project of this size.

  • ZipArchive php Class, would this be the best approach??

    - by SoLoGHoST
    Ok, just wondering on the versions of PHP that this class is built into. And if they are built into all platforms (OS's). I'm wanting an approach to search through a zip file and place files using file_put_contents in different filepaths within the webroot. In any case, I'm familiar with how to do this with the ZipArchive class, but I'm wondering if using this class would be a good solution and support MOST, if not ALL servers?? I mean, I'd rather not use a method that requires the Server to have it installed. I'm looking for a solution to this that will support at least MOST servers without having to install the class... Thanks :) Also, I'd like to support opening tar.gz and/or .tgz files if possible, but I don't think the ZipArchive class supports this, but perhaps a different built-in php class does??

  • How do I best do balanced quoting with Perl's Regexp::Grammars?

    - by Evan Carroll
    Using Damian Conway's Regexp::Grammars, I'm trying to match different balanced quoting ('foo', "foo", but not 'foo") mechanisms -- such as parens, quotes, double quotes, and double dollars. This is the code I'm currently using. <token: pair> \'<literal>\'|\"<literal>\"|\$\$<literal>\$\$ <token: literal> [\S]+ This generally works fine and allows me to say something like: <rule: quote> QUOTE <.as>? <pair> My question is how do I reform the output, to exclude the needles notation for the pair token? { '' => 'QUOTE AS \',\'', 'quote' => { '' => 'QUOTE AS \',\'', 'pair' => { 'literal' => ',', '' => '\',\'' } } }, Here, there is obviously no desire to have pair in between, quote, and the literal value of it. Is there a better way to match 'foo', "foo", and $$foo$$, and maybe sometimes ( foo ) without each time creating a needless pair token? Can I preprocess-out that token or fold it into the above? Or, write a better construct entirely that eliminates the need for it?

  • What is the best way to interoperably serialize a message?

    - by iwein
    I'm considering message serialization support for spring-integration. This would be useful for various wire level transports to implement guaranteed delivery, but also to allow interoperability with other messaging systems (e.g. through AMQP). The fundamental problem that arises is that a message containing Java object in it's payload and headers should be converted to a byte[] and/or written to a stream. Java's own serialization is clearly not going to cut it because that is not interoperable. My preference would be to create an interface that allows the user to implement the needed logic for all Objects that take part in serialization. Is this a sensible idea and what would the interface look like? Is there a standard interoperable way to serialize Objects that would make sense in this context?

  • How best to calculate derived currency rate conversions using C#/LINQ?

    - by chillitom
    class FxRate { string Base { get; set; } string Target { get; set; } double Rate { get; set; } } private IList<FxRate> rates = new List<FxRate> { new FxRate {Base = "EUR", Target = "USD", Rate = 1.3668}, new FxRate {Base = "GBP", Target = "USD", Rate = 1.5039}, new FxRate {Base = "USD", Target = "CHF", Rate = 1.0694}, new FxRate {Base = "CHF", Target = "SEK", Rate = 8.12} // ... }; Given a large yet incomplete list of exchange rates where all currencies appear at least once (either as a target or base currency): What algorithm would I use to be able to derive rates for exchanges that aren't directly listed? I'm looking for a general purpose algorithm of the form: public double Rate(string baseCode, string targetCode, double currency) { return ... } In the example above a derived rate would be GBP-CHF or EUR-SEK (which would require using the conversions for EUR-USD, USD-CHF, CHF-SEK) Whilst I know how to do the conversions by hand I'm looking for a tidy way (perhaps using LINQ) to perform these derived conversions perhaps involving multiple currency hops, what's the nicest way to go about this?

  • What is the best way to access Google Calendar from ruby?

    - by Jakub Hampl
    I'm writing an app for a company that uses Google Calendar internally and would need to use events they already have in their calendar in the app. So I need to get read only access to their calendars from the app (namely I need the events title, start and end dates and attendee emails for all future events). What is the simplest way to do this in ruby (I would need it to work relatively seamlessly on Heroku)? I tried using the GCal4Ruby gem which seemed the least outdated of the ones I found but I'm unable to even authenticate through the library (HTTPRequestFailed - Captcha required error) let alone get the info I need.
