  • Could the UIHint attribute accept a property of the current class ?

    - by user252160
    I found the follwing code in MSDN . How can I change this "UnitsInStock" with a value that my Product class has. For instance, Product has a FieldType property which has a string property called Name. I'd like to use that FieldType.Name property instead of hardcoding with a string. However, I cannot specify "this", or the current instance as an argument of the UIHint attribute . Please, help using System; using System.Web.DynamicData; using System.ComponentModel.DataAnnotations; [MetadataType(typeof(ProductMetadata))] public partial class Product { } public partial class ProductMetadata { [UIHint("UnitsInStock")] [Range(100, 10000, ErrorMessage = "Units in stock should be between {1} and {2}.")] public object UnitsInStock; }

  • Deliver files from a web server from outside the web app

    - by Ankur
    Is there anyway to serve a file from a web server through the web, that is not within the web application. I am using Tomcat and a Java servlets based application. I don't want to put the files within the webapp because they are several 100GB and I will have to replace them every time I update the WAR if I put them inside it.

  • Best practices for developing simple ASP.NET sites (built in controls or JQuery + scripts)

    - by Nix
    I was recently reviewing some code written by two different contractors, both were basic ASP.NET management sites. The sites allowed the user to view and edit data. Pretty much simple CRUD gateways. One group did their best to use built in ASP + AJAX Toolkit controls and did their best to use as many built in controls as possible. I found the code much easier to read and maintain. The other used jQuery and the code is heavily marked up with script blocks which are then used to build pages from javascript files. Which one is more common? The one that basically leveraged embedded HTML markup in scripts controled by javascript files screams readability and maintenance issues? Is this just the way of doing asp dev with jQuery? Assuming the second example happens a lot, are there tools that help facilitate jQuery development with visual studio? Do you think they generated the html somewhere else and just copied it in? Example Script block: <script id="HRPanel" type="text/html"> <table cellpadding='0' cellspacing='0' class="atable"><thead class="mHeader"><tr><th>Name</th><th>Description</th><th>Other</th></thead><tbody> <# for(var i=0; i < hrRows.length; i++) { var r = HRRows[i]; #> <tr><td><#=r.Name#></td><td><#=r.Description#></td><td class="taRight"><#=r.Other#></td></tr> <#}#> </tbody><tfoot><th></th><th></th><th></th></tfoot></table> </script> Then in a separate location (js file) you would see something like this. $("#HRPanel").html($("#HRPanel").parseTemplate({ HRRows: response.something.bah.bah }));

  • MVC2: "File not found" after view is painted

    - by Dave Hanna
    This is wierd. First, I'm building a site based on someone else's framework (Piers Lawson: Creating a RESTful Web Service using MVC ), so I'm not entirely sure what's going on under the covers. But when I run it in VS 2010 by pressing F5, it brings up the Home page, and THEN traps an error in Application_Error. The error is "File does not exist" exception. But I have no idea what file it's looking for. Where does flow control go after the View is finished displaying? How can I break to find out what it's looking for?

  • ASP.NET Development Server - Empty webResource.axd after conversion from 2.0 to 3.5

    - by David Casey
    I have moved a project from asp.net 2.0 to 3.5. The original project was using the atlas ajax extensions so I have modified the code to use the built in ajax features in 3.5. When running the project within the dev environemnt (VS2008 on Vista Business SP1) and using the asp.net dev server I receive javascript errors such as WebForm_PostBackOptions which point to a missing handler/module. If I deploy the project and run it stand alone within IIS or if I use Fiddler2 while running in VS2008 I do not see the errors and fiddler shows that the axd files are being downloaded correctly. Also deploying to a 2003 server does not show any issues. I could just carry on and forget this as it works when deployed but I would like to understand what is happening. Has anyone got an ideas as to what is going on here and how to get the same results accross all environments?

  • Using Python and Mechanize with ASP Forms

    - by tchaymore
    I'm trying to submit a form on an .asp page but Mechanize does not recognize the name of the control. The form code is: <form id="form1" name="frmSearchQuick" method="post"> .... <input type="button" name="btSearchTop" value="SEARCH" class="buttonctl" onClick="uf_Browse('dledir_search_quick.asp');" > My code is as follows: br = mechanize.Browser() br.open(BASE_URL) br.select_form(name='frmSearchQuick') resp = br.click(name='btSearchTop') I've also tried the last line as: resp = br.submit(name='btSearchTop') The error I get is: raise ControlNotFoundError("no control matching "+description) ControlNotFoundError: no control matching name 'btSearchTop', kind 'clickable' If I print br I get this: IgnoreControl(btSearchTop=) But I don't see that anywhere in the HTML. Any advice on how to submit this form?

  • SQL CLR Stored Procedure and Web Service

    - by Nathan
    I am current working on a task in which I am needing to call a method in a web service from a CLR stored procedure. A bit of background: Basically, I have a task that requires ALOT of crunching. If done strictly in SQL, it takes somewhere around 30-45 mins to process. If I pull the same process into code, I can get it complete in seconds due to being able to optimize the processing so much more efficiently. The only problem is that I have to have this process set as an automated task in SQL Server. In that vein, I have exposed the process as a web service (I use it for other things as well) and want the SQL CLR sproc to consume the service and execute the code. This allows me to have my automated task. The problem: I have read quite a few different topics regarding how to consume a web service in a CLR Sproc and have done so effectivly. Here is an example of what I have followed. http://blog.hoegaerden.be/2008/11/11/calling-a-web-service-from-sql-server-2005/ I can get this example working without any issues. However, whenever I pair this process w/ a Web Service method that involves a database call, I get the following exceptions (depending upon whether or not I wrap in a try / catch): Msg 10312, Level 16, State 49, Procedure usp_CLRRunDirectSimulationAndWriteResults, Line 0 .NET Framework execution was aborted. The UDP/UDF/UDT did not revert thread token. or Msg 6522, Level 16, State 1, Procedure MyStoredProc , Line 0 A .NET Framework error occurred during execution of user defined routine or aggregate 'MyStoredProc': System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.EnvironmentPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. System.Security.SecurityException: at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.CodeAccessPermission.Demand() at System.Net.CredentialCache.get_DefaultCredentials() at System.Web.Services.Protocols.WebClientProtocol.set_UseDefaultCredentials(Boolean value) at MyStoredProc.localhost.MPWebService.set_UseDefaultCredentials(Boolean Value) at MyStoredProclocalhost.MPWebService..ctor() at MyStoredProc.StoredProcedures.MyStoredProc(String FromPostCode, String ToPostCode) I am sure this is a permission issue, but I can't, for the life of me get it working. I have attempted using impersonation in the CLR sproc and a few other things. Any suggestions? What am I missing?

  • asp.net: deploying local resources - is embedding possible?

    - by chris
    I have an asp.net app with some local resources. These resources are used in the aspx and code-behind files: aspx: <asp:TextBox ID="TextBox1" runat="server" Text="<%$ Resources:testTag %>" /> .vb: TextBox1.Text = GetLocalResourceObject("testTag").ToString If I deploy the .resx files with the app, there are no problems. However, if I change the build action on the resx file to "Embedded Resource", the resources aren't available, even though they're in the DLL that gets built. Is it possible to deploy resources in a DLL, or am I stuck with managing & deploying resx files on the server?

  • Facebook canvas app ASP.NET MVC HttpException: Invalid Model

    - by zznq
    I am working on a Facebook tab application. I am using asp.net MVC 2 with the "official" Microsoft Facebook SDK. Most of my views are working just fine. However, I have one that is causing a huge mess. I am simply returning a List<Tags> to the view and as my ViewModel. This problematic view is simply displaying the list in a foreach loop. Whenever navigate to this view I get a "System.Web.HttpException: Invalid Model" exception. The most puzzling part of all this is that the same code is running without fail on our regular(non-Facebook) app that works just fine with the same code. Any insight into why Facebook and asp.net MVC 2 would be causing this behavior would be much appreciated.

I want skills that will enable me to write apps for <--insert hottest web trend here-- (Facebook & iphone apps for example) This is one of my goals as far as Tech. is concerned. I'd also like to have a brod knowledge of different areas of IT. I'm looking into majoring in "Computing & Security Technology". The program is offered by Drexel in conjunction with my CC. It's a 4 year degree. Can someone take a look @ the pdf below. It outlines every course I must take. http://www.drexelatbcc.org/academics/PDF/CST_CT.pdf For degree requirments w/ links to course descriptiongs see drexel.edu/catalog/degree/ct.htm With electives I can go up to Web Development 4. Based on my goals of Web development & wanting a well rounding education in information technology, what do you think of the curriculum? How will I fare entering the job market with this degree?

  • Recursive TreeView in C# ASP.NET

    - by waqasahmed
    I have an object of type list from which I wish to use to populate a treeview in asp.net c#. Each object item has: id | Name | ParentId so for example: id | Name | ParentId 1 | Alice | 0 2 | Bob | 1 3 | Charlie | 1 4 | David | 2 In the above example, the parent would be Alice having two children Bob and Charlie. David is the child of Bob. I have had many problems trying to dynamically populate the treeview recursively in c# ASP.NET Does any one have a simple solution? Btw: you can use People.Id, People.Name and People.ParentId to access the members since it is an object belonging to list. I can post you my code so far (many attempts made) but not sure how useful it will be.

  • Web Hosting Plan

    - by Laith J
    I'm looking for a new web hosting service, currently I'm using GoDaddy's Economy plan but it offers only PHP server-side scripting. For my next project it looks like I'm gonna need to use Java. Currently I pay ~60 USD per year for both the domain and the web hosting plan. Anyone knows of a web hosting service that supports Java and isn't much more expensive than this? Thanks, God bless

  • Problems with WiX and Visual Studio web deployment project

    - by Valeriu
    Hello, I want to create an .MSI package from a web deployment project in Visual Studio 2008. Now we want to use continuous integration and we would need the .MSI package build in the nightly builds. Till now we used standard Visual Studio Web Setup project, but this is not compatible with the MSBuild. So we decided to use WiX. The problem is that I have not found any good tutorial/documentation about this. Is there a way to do a WiX installer package from a web deployment project? If yes, how? Also, I tried to use heat.exe to create the XML for the WiX project .wxs file, but it seems that heat.exe doesn't recognize the web deployment project format. Thank you for your responses. Regards, V.

  • 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.

  • Putting CAPTCHAs on their own page?

    - by mnemosyn
    We need to put a captcha image on our ASP.NET MVC 2 based website. We chose reCaptcha and built it in using the way described by Derik Whittaker. The idea there is baiscally to build some abstractions and all you need to do is decorate your Controller with a [ValidateCaptcha] attribute. This works all fine. However, we have a lot of form-widgets in different pages and I don't want to have the captcha floating around everywhere. So I'd like to implement it the way StackOverflow does: Submit a Form -> Challenge Captcha -> Submit Captcha -> Perform Action on original form data. Now, how do I redirect the user to the captcha page while keeping the originally submitted information? I thought of some very ugly hacks (hidden fields w/ base64 encoded form data, etc.) but I think I'm missing something obvious. On the other hand, this sounds as if I wanted to do something in a stateful manner, and I shouldn't?

  • ASP.NET variable scope

    - by c11ada
    hey all, im really new to ASP.Net and still havnt got my head round most of the concepts, im really having problems with variable, when creating a desktop application, any variable created in code for example int n = 10; this variable will be there until the program is running right. but in asp iv created variables which are supposed to last until the user gets of that page, so for example say i have a page which takes the users value ( call this variable n say the user type in 10) and every time the user presses the next button the code add 10 to this value. so the first time the user presses the next button n= n + 10; what i have found is no matter how many times i press the next button n will always equal 20, because the previous value is not saved !! these values are populated the first time the user enters that page, once the user clicks the next button the content of these values disappear! how can stop this from happening ?? hope this makes sense !! thanks

  • ASP.NET Asynchronous Tasks - Worker Thread Not Releasing?

    - by user296752
    I am having an issue with testing asynchronous tasks in ASP.NET & IIS7. From what I have read, the worker thread should be released back into the thread pool while the I/O thread performs the async work, allowing ASP.NET to server other incoming requests. But when I simulate heavy load on the web application by making 20 simultaneous requests to a page (async.aspx) that performs long running async tasks, I am unable to browse to some other normal aspx page until the requests are just about done. Am I misunderstanding or missing something here? I am running Vista Biz x64, VS2008 + IIS7. I have the Async attribute applied to the Page directive.

  • Accessing and binding events to an ASP.NET Grid view using Jquery

    - by Sayem Ahmed
    I have an ASP page which displays a text box when it loads. It takes an input number, send it to the server through post back, and then displays some record in a grid view. After a number is input into the box, the server fetches some data from a database and add records to the grid view. It also contains a link column, whose URL is set to "#", so that the page isn't redirected when it is clicked. Now I want to bind a jquery "click" event to that link. How can I do that ? I have tried that to do myself but failed, because it is not available when the DOM is loaded (since it only contains rows when a number is input through the box), and is being modified through ASP.NET Ajax post back.
