  • VisualBasic.net Database Boiler Plate

    - by Shiftbit
    Is there any built in .net Classes to assist in the reduction of boiler plate code? I have numerous database operations going on and I find that I am reproducing the connection, command, transaction and occassianlly data set. I am aware of the Java Related Question, however, the solutions pertain to Java. I was wondering if anyone was aware of a .net solution? http://stackoverflow.com/questions/1072925/remove-boilerplate-from-db-code Public Sub ReadData(ByVal connectionString As String) Dim queryString As String = "SELECT EmpNo, EName FROM Emp" Using connection As New OracleConnection(connectionString) Dim command As New OracleCommand(queryString, connection) connection.Open() Using reader As OracleDataReader = command.ExecuteReader() ' Always call Read before accessing data. While reader.Read() Console.WriteLine(reader.GetInt32(0).ToString() + ", " _ + reader.GetString(1)) End While End Using End Using End Sub MSDN

  • Where Are the Release Versions of ASP.Net AJAX 4.0 Templating Files?

    - by Lee Richardson
    I'm trying to get the production version of ASP.Net AJAX 4.0 Templating working and can't find the JavaScript files. With the beta version I needed to reference MicrosoftAjaxTemplates.js, MicrosoftAjaxAdoNet.js, and MicrosoftAjaxDataContext.js. I can get everything to work with the beta CDN versions (e.g. http://ajax.microsoft.com/ajax/beta/0911/MicrosoftAjaxTemplates.js). But for the life of me I can't find 1. The release CDN versions of these files or 2. Where to download the whole Release ASP.Net AJAX 4.0 JavaScript package. The files certainly are not listed on the ASP.Net AJAX 4.0 CDN at http://www.asp.net/ajaxlibrary/CDNAjax4.ashx. Maybe the files have been renamed? Theoretically this should be a rediculously easy question and I'm a little embarrased to even ask it on StackOverflow, but I've had no luck finding an answer on my own. Any help would be much appreciated. Thanks, - Lee

  • Exposing warnings\errors from data objects (that are also list returned)

    - by Oren Schwartz
    I'm exposing Data objects via service oriented assembly (which on future usages might become a WCF service). The data object is tree designed, as well as formed from allot of properties.Moreover, some services return one objects, others retrieve a list of them (thus disables throwing exceptions). I now want to expose data flow warnings and wondering what's the best way to do it having to things to consider: (1) seperation (2) ease of access. On the one hand, i want the UI team to be able to access a fields warnings (or errors) without having them mapping the field names to an external source but on the other hand, i don't want the warnings "hanged" on the object itself (as i don't see it a correct design). I tought of creating a new type of wrapper for each field, that'll expose events and they'll have to register the one's they care about (but totally not sure) I'll be happy to hear your thoughts. Could you please direct me to a respectful design pattern ? what dp will do best here ? Thank you very much!

  • Determine which mouse was clicked (multiple mice devices) in .NET

    - by Morten K
    Hi, I want to detect when my touchpad is clicked! I normally use a usb mouse, so I don't use the touchpad for anything. Instead I'd like to make it possible to perform an action in .NET, when the touchpad is clicked. This way I can use it as a shortcut: One tap and something cool happens. Is this possible, and if yes, any clue how? I'd prefer if it could be working in VB.NET or C#. My theory is that I'd have to make a mousehook, which then somehow determines which device the click is coming from. If the click is determined to be from the touchpad, then cancel the click and doWhatever(). Thanks!

  • What is your favorite convention for organizing a ASP.NET project?

    - by Michael Rosario
    Hello world. My team is starting a brand new ASP.NET solution which will probably become large. Inspired by ASP.NET MVC, we currently express all data access objects in a model project. We, however, do not have good conventions for organizing ASP.NET ascx's and aspx's. We have already reviewed DotNetNuke and want to avoid the complexity of driving the whole application through a single default.aspx . What is the best way to organize a non-MVC ASP.NET solution? Your tips, links, and advice are greatly appreciated!

  • Quickly generate/publish RSS feeds from ASP.NET projects?

    - by jdk
    Under a timeline, therefore the salient point is "quickly" and willing to throw some $ at it too (doesn't have to be a free solution). Looking for an RSS feed generator usuable in .NET framework 2.0. Ideally it would be easy to use (inferred quick) but flexible enough to support the multiple standards (shown part way down this page). We have the business classes in .NET and want to publish RSS feeds on the ASP.NET website. Any software that's good? Doesn't have to be free. Must support .NET framework 2.0 Thanks.

  • Is it better to define all routes in the Global.asax than to define separately in the areas?

    - by Matthew Patrick Cashatt
    I am working on a MVC 4 project that will serve as an API layer of a larger application. The developers that came before me set up separate Areas to separate different API requests (i.e Search, Customers, Products, and so forth). I am noticing that each Area has separate Area registration classes that define routes for that area. However, the routes defined are not area-specific (i.e. {controller}/{action}/{id} might be defined redundantly in a couple of areas). My instinct would be to move all of these route definitions to a common place like the Global.asax to avoid redundancy and collisions, but I am not sure if I am correct about that.

  • Is PluralSight worth the cost [closed]

    - by B Woods
    I am an looking at a few different supplemental learning courses to help me beef up my skills but unsure which one to use. I am interested in PluralSight because I work for the government and they use all Microsoft technologies for the most part. I like the courses on PluralSight but the price tag is pretty hefty. I am not sure how good the courses are because I cannot view the ones I want so I am a tad bit skeptical. I am sure some of you have PluralSight, do you think its a good investment for your learning or should I just stick with books/internet? Any suggestions?

  • Admin Panel like Custom Framework

    - by bhuvin
    I want to Create a Framework , like Admin panel , which can rule almost all the aspects of what is shown on the frontend. For an (most basic) example: If suppose the links which are to be shown in a navigation area is passed from the server, with the order and the url , etc. The whole aim is to save the time on the tedious tasks. You can just start creating menus and start assigning pages to it. Give a url, actual files which are to be rendered (in case of static files.), in case of dynamic files, giving the file accordingly. And all this is fully server side manageable using different portlets, sort of things. So basic Roadmap is having : Areas like: Header Area - Which can contain logos, links etc. Navigation Area - Which can contains links and submenus. Content Area - Now this is where the tricky part is that that it has zones like: left, center & right. It contains Order in which it has to be displayed. So, when someday we want to change the way the articles appear on the page, we can do so easily, without any deployments. Now these zones can have n number of internal elements, like the word cloud, or the advertisement area. Footer Area: Again similar as Header Area. Currently there is a preexisting custom framework, which uses XSLT files for pulling out data from the server side. And it has the above capabilities. For example: If there's a grid it will be having a <table> tag embedded in the XSLT file. Now whatever might be the source of the data, we serialize this as XML and give it to the XSLT file and the html is derived from this and is appended to the layer in a page. The problem with this approach is: The XSLT conversion is occurring on the server side, so the server is responsible for getting the data, running XSLT transform, and append the html generated to the layer div. So, according to me, firstly this isn't the server's concern to do so. Secondly for larger applications this might be slower. Debugging isn't possible for XSLT transformation. So, whenever we face problems with data its always a bit of a trial & error method. Maintaining it is a bit of an eerie job i.e. styling changes, and other stuff. Adding dynamic values. Like JavaScript can't actually be very easily used in this. Secondly, we can't use JQuery or any other libraries with this since this is all occurring on the server. For now what I have thought about is using Templating - Javascript - JSON combination in place of XSLT, this will be offloaded to the client and the rendering will take place accordingly. This could solve the above problems and also could add mobile support for the same. Only problem which I could think of is that: It is much work and adding new portlets on the go needs to be looked into. What could be the alternatives for this? What kind of problems are there with the JavaScript approach? What are the different ways to implement the same? Are there any existing frameworks for similar usage?

  • Is MochaHost as good as it sounds?

    - by gilly3
    It's time for me to find a new web host, and I'm a bit overwhelmed by the selection. I need a Windows host. One provider that seems to stand out is MochaHost. Here are a few of the things that look amazing to me: 2 free domains for life. 2!! MS SQL Support - Unlimited Databases 5,000 sites $3.33/month Unlimited everything (traffic, storage, domains, etc.) Is MochaHost too good to be true? Maybe it is notoriously unreliable (despite their 100% uptime guarantee)? Are there other considerations I may be forgetting?

  • Which is the "best" data access framework/approach for C# and .NET?

    - by Frans
    (EDIT: I made it a community wiki as it is more suited to a collaborative format.) There are a plethora of ways to access SQL Server and other databases from .NET. All have their pros and cons and it will never be a simple question of which is "best" - the answer will always be "it depends". However, I am looking for a comparison at a high level of the different approaches and frameworks in the context of different levels of systems. For example, I would imagine that for a quick-and-dirty Web 2.0 application the answer would be very different from an in-house Enterprise-level CRUD application. I am aware that there are numerous questions on Stack Overflow dealing with subsets of this question, but I think it would be useful to try to build a summary comparison. I will endeavour to update the question with corrections and clarifications as we go. So far, this is my understanding at a high level - but I am sure it is wrong... I am primarily focusing on the Microsoft approaches to keep this focused. ADO.NET Entity Framework Database agnostic Good because it allows swapping backends in and out Bad because it can hit performance and database vendors are not too happy about it Seems to be MS's preferred route for the future Complicated to learn (though, see 267357) It is accessed through LINQ to Entities so provides ORM, thus allowing abstraction in your code LINQ to SQL Uncertain future (see Is LINQ to SQL truly dead?) Easy to learn (?) Only works with MS SQL Server See also Pros and cons of LINQ "Standard" ADO.NET No ORM No abstraction so you are back to "roll your own" and play with dynamically generated SQL Direct access, allows potentially better performance This ties in to the age-old debate of whether to focus on objects or relational data, to which the answer of course is "it depends on where the bulk of the work is" and since that is an unanswerable question hopefully we don't have to go in to that too much. IMHO, if your application is primarily manipulating large amounts of data, it does not make sense to abstract it too much into objects in the front-end code, you are better off using stored procedures and dynamic SQL to do as much of the work as possible on the back-end. Whereas, if you primarily have user interaction which causes database interaction at the level of tens or hundreds of rows then ORM makes complete sense. So, I guess my argument for good old-fashioned ADO.NET would be in the case where you manipulate and modify large datasets, in which case you will benefit from the direct access to the backend. Another case, of course, is where you have to access a legacy database that is already guarded by stored procedures. ASP.NET Data Source Controls Are these something altogether different or just a layer over standard ADO.NET? - Would you really use these if you had a DAL or if you implemented LINQ or Entities? NHibernate Seems to be a very powerful and powerful ORM? Open source Some other relevant links; NHibernate or LINQ to SQL Entity Framework vs LINQ to SQL

  • Storing images in file system and returning URLs or virtually resizing and returning byte arrays?

    - by ismaelf
    I need to create a REST web service to manage user submitted images and displaying them all in a website. There are multiple websites that are going to use this service to manage and display images. The requirements are to have 5 pre-defined image sizes available. The 2 options I see are the following: The web service will create the 5 images, store them in the file system and and store the URL's in the database when the user submits the image. When the image is requested, the web service will return an array of URLs. I see this option to be a little hard on the hard drive. The estimates are 10,000 users per site, and lets say, 100 sites. The heavy processing will be done when the user submits the image and each image is going to be pulled from the File System. The web service will store just the image that the user submits in the file system and it's URL in the database. When the user request images, the web service will get the info from the DB, load the image on memory, create its 5 instances and return an object with 5 image arrays (I will probably cache the arrays). This option is harder on the processor and memory. The heavy processing will be done when the images get requested. A plus I see for option 2 is that it will give me the option to rewrite the URL of the image and make them site dependent (prettier) than having a image repository for all websites. But this is not a big deal. What do you think of these options? Do you have any other suggestions?

  • New to VS.net (VB.net) 2008. Windows 7 aero glass stuff.

    - by StealthRT
    Hey all, i have been using VB.net 2008 for a few months and i have a question. I compiled my program and ran it in a VM running windows 7. However, the progress bar looks like it does in XP. It doesn't have that cool look to it like I've seen in many other programs running in windows 7. I have downloaded the 3.5 .net framework with sp1 and also the sdk for windows 7 (1.4+ gb dvd) but i still see nothing. Is there a check-box i am missing in VS 2008 to enable these types of features? Maybe some type of code i need to place in the program? Thanks! David

  • Best way to reuse common functions between ASPX pages ?

    - by DFord
    I have a bunch of functions that are used across multiple ASPX files. I want to condense these down to one file to be used for all the ASPX files. I have a few ideas but I want to know what the accepted method to doing this would be. I have an idea to just create a class to put them in. However, I was wondering if i could put them in a ascx page, but that does not look like the solution I'm looking for. Is there a accepted method for this type of situation?
