  • Simple Windows.Forms binding is failing using framework 4.0.

    - by jyoung
    This works under the .net framework 3.5 client. This fails under the .net framework 4.0 client. Was I doing something that was illegal under 3.5 but just happened to work, or is this a bug? Note that in my project 'PropInt' does not raise change events so using ctx[obj1.PropObj2, "PropInt"] is not an option. public class Obj1 { public Obj2 PropObj2 { get; set; } public Obj1() { PropObj2 = new Obj2(); } } public class Obj2 { public int PropInt { get; set; } } static class Program { [STAThread] static void Main() { var ctx = new BindingContext(); var obj1 = new Obj1(); var x1 = ctx[obj1, "PropObj2.PropInt"]; } }

  • .NET Remoting Client's Problem when running on the machine with Multi NICs

    - by cui chun
    I built a .NET Remoting Client which works quite fine on the machine of single NIC, and lots of testing messages received via remoting event. But when additional NIC was added, the Client seemed to be able to connect the remoting Server, but the testing messages cannot arrive anymore. From debugging, the server end did trigger the event but the client didn't get that. Checking from google and find that a similar problem report: http://www.eggheadcafe.com/community/aspnet/2/10061570/reply.aspx I just wonder if any solutions? Thanks in advance!

  • Optimize loading an XAP file with an asp.net website

    - by theoneawaited
    I've been developing a game using Silverlight 4 and silversprite (http://silversprite.codeplex.com/) This game is HEAVILY content dependent, using a lot of audio and images. My content folder is around 90 mbs worth of stuff. And because of that, my XAP file is around 60 MB, and takes 5 minutes to download from the website before any user can start playing. I am using Visual Web Developer 2010 to create my site and load the XAP. Is there a way where I can take content out of my XAP and put it in my ASP.net site project? Or perhaps upload my content files to the site's storage? This would make my XAP file much quicker to download. Anyone have suggestions? Thanks!

  • Different kinds of doubles in vb.net?

    - by Jonathan
    Hey all- I'm using QBFC to generate invoices in a Quickbooks integrating app. I'm getting an exception thrown for lineItem.Amount.SetValue(val as Double) when I try to enter a programmatically generated double. The following does not work: lineItem = invoice.ORInvoiceLineAddList.Append.InvoiceLineAdd Dim amount as Double amount = summary.dailySold * summary.dailyRate loggingTxtBox.AppendText("Amount is " & amount & vbNewLine) lineItem.Amount.SetValue(amount) The exception I receive is System.Runtime.InteropServices.COMException (0x80040305): Invalid Amount format. at Interop.QBFC8.IQBAmountType.SetValue(Double val) The following works: lineItem.Amount.SetValue(20.3) Any suggestions? Is .NET interpretting a hard-coded double differently than a programmatically calculated one? Thanks- Jonathan

  • Asp.net Site on GoDaddy Loads Slowly

    - by Randy
    I just published a very small site to GoDaddy that I programmed in Microsoft Visual Web Developer 2008. The site only contains 6 sheets, none of which are data intensive. Each has a few small images that serve mostly to navigate to the other sheets. There is no data, no SQL, nothing like that. There is one master page that governs the page layout for all of the pages. Everything works fine, for the most part. I am posting because the site loads quite slowly, particularly considering how little content is being loaded. Can anybody give me any advice about what I should look at to speed this thing up a little bit? Is this an asp.net issue? Use of master pages? Godaddy? Something else? I'm a newbie, so speak slowly. Thanks.

  • How to name an event handler of a private variable in Vb.Net following FxCop rules and Vb.Net standa

    - by SoMoS
    Hello, On one side, in Vb.Net when you add an event handler to an object the created method is named: <NameOfTheObject>_<NameOfTheMethod>. As I like to have consistent syntax I always follow this rule when creating event handlers by hand. On the other side when I create private variables I prefix them with m_ as this is a common thing used by the community, in C# people use to put _ at the beginning of a variable but this is no CLS compliant. At the end, when I create event handlers for events raised by private variables I end with Subs like m_myVariable_MyEvent. Code Analysis (Fx Cop) is complainig about this way of naming because the method does not start with uppercase and because the _, so the question is: What naming standards do you follow when creating event handlers by hand that follow the Fxcop rules if any? Thanks in advance.

  • Obtain stored procedure metadata for a procedure within an Oracle package using ADO.NET

    - by alwayslearning
    Hi, I am trying to obtain the stored procedure metadata (procedure name,parameter types,parameter names etc) for a procedure declared within an Oracle package, using the standard ADO.NET API - DbConnection.GetSchema call. I am using the ODP driver. I see that the Package is listed in the 'Packages' and 'PackageBodies' metadata collections. The procedure parameter appears in the 'Arguments' and 'ProcedureParameters' collections. I do not see a way to get to the procedure information via the package metadata. Even if the procedure does not have any parameters there is a row in the 'ProcedureParameters' collection for this procedure. My question: To obtain the procedure metadata do I have to query the 'ProcedureParameters' collection and search for an entry with the required package name? I can then construct the procedure metadata based on the parameter information. Is there a shorter or quicker way to obtain the same information?

  • MVP - asp.net - passing information via views - confused

    - by ekynox
    Hi, I've just started to play around with MVP in asp.net. One thing I quite cant figure out is how do I pass information, i.e. an integer variable from one view(webform) to another. Let's I have a customerlistView which is mapped to a customerlist.aspx page. From it I select a customer and it's record id. Say I want to display the customer's details in another view (i.e customerDetailView, customerdetail.aspx). How do I achieve that ? Does that mean customerlistView would call the presenter of the customerdetail and cause a page redirect ? Any ideas ? thanks

  • Store previous search criteria using ASP.NET

    - by thatuxguy
    I have created a web application which returns a list of products. On this page it allows users to search for a range of different search criteria. Once a user searches and the results are returned to the table on the page a user can then edit a product. However upon returning to the product listing page the page just reloads, and shows all products again. I would like to know what the best way would be to keep the search results, and upon returning to the search page it keeps the previous criteria. I have found a few posts on stack exchange - Best way to store previous search criteria in ASP.NET - is probaly one of the better ones. Does any one know how i could go about keeping the search criteria, so when a user returns to the search page, the previous search criteria and results stay the same. Many thanks.

  • ASP.NET WebMethod Returns JSON wrapped in quotes

    - by CL4NCY
    Hi, I have an asp.net page with a WebMethod on it to pass JSON back to my javascript. Bellow is the web method: [WebMethod] public static string getData(Dictionary<string, string> d) { string response = "{ \"firstname\": \"John\", \"lastname\": \"Smith\" }"; return response; } When this is returned to the client it is formatted as follows: { \"d\": \"{ \"firstname\": \"John\", \"lastname\": \"Smith\" }\" } The problem is the double quotes wrapping everything under 'd'. Is there something I've missed in the web method or some other means of returning the data without the quotes? I don't really want to be stripping it out on the client everytime. Also I've seen other articles where this doesn't happen. Any help would be appreciated thanks.

  • ASP.NET: CSS friendly calendar control

    - by pbz
    I'm using the built-in Calendar control. It works, but in a few places the way the HTML is rendered is broken or not CSS-friendly and unfortunately cannot be changed (it's hard coded). I was hoping they would fix this in .NET 4.0, but as far as I can tell the Calendar control hasn't been changed at all. Also, as far as I know, there's no CSS adapter for the Calendar control. So, I would need a control that would: Allow me to customize the content of each cell (like OnDayRender works) Allow me to assign CSS classes to any HTML it may render Not render anything automatically that cannot be turned off, except layout code No auto-postback or auto-JS code (I can handle these by hand using simple links or custom JS calls) Basically a simple calendar view control that would give me full rendering control. What would you recommend? Thanks!

  • Using Entity Framework, how do I specify a sort on a navagation property?

    - by Jared
    I have two tables: [Category], [Item]. They are connected by a join table: [CategoryAndItem]. It has two primary key fields: [CategoryKey], [ItemKey]. Foreign keys exist appropriately and Entity has no problem pulling this in and creating the correct navigation properties that connect the entity objects. Basically each category can have multiple items, and items can be in multiple categories. The problem is that the order of items is specified per category, so that a particular item might be third in one category but fifth in another. In the past, I have added a [Sequence] field to the join table and modified the stored procedure to handle it. But since Entity is replacing my stored procedures, I need to figure out how to make Entity handle the sequence. Any suggestions?

  • Accessing NHibernate Repository using ASP.NET Ajax WebMethod

    - by LooDaFunk
    Hi there! on my page I have a save button that gets the values from the form and then saves it in the database using NHibernate. This works using ASP.net postback buttons. I have now added an Ajax WebMethod to make things sleek and quicker. Howver, when trying to access the data in the repository it doesn't seem to get it. I am passing in the correct values, and everything looks the same as when you are using the postback but no Joy! I should point out here that I'm a newbie with NHibernate and I'm working with someone elses code. Here's the code: the main problem is this line: Solution.Entities.Hierarchy.Tag tag = tagRep.Get(tagId); The tagID is fine, but when it does the get no exception is raised it just comes out the method and goes back to the page???? http://pastebin.com/cBTp9pnC Anyone have any ideas? Merry Christmas!

  • ASP.NET OutPutCache VaryByParam and VaryByHeader with AJAX

    - by DennyDotNet
    I'm trying to do some caching using VaryByParam AND VaryByHeader. When an AJAX request comes in I return a partial XHTML. When a regular request comes in I send the partial XHTML page with header / footer. I tried to cache the page by doing: [OutputCache( Duration = 5, VaryByParam = "nickname,page", VaryByHeader = "X-Requested-With" )] However this doesn't work... if I do a regular request first then run the AJAX call I get the full cached page instead of the partial and vice-versa. Seems like VaryByHeader is being ignored. Is it because X-Requested-With is omitted on normal requests? Or perhaps it's doing VaryByParam OR VaryByHeader? My obvious way around this is for AJAX requests to call a different method which only returns partial pages, however I'd like to avoid that if possible. I'm using ASP.NET MVC 1.0 with the OutputCacheAttribute.

  • ASP.NET/AJAX - Timer delay

    - by Julian
    I've got a problem with the timer in asp.net ajax. The timer needs to trigger every second so I put the delay of the timer (don't know the real name atm) at 1000. Now when I put this timer inside an UpdatePanel it doesn't really trigger every second because the timer also gets updated in the UpdatePanel. But when I put the timer outside the update panel it keeps kinda refreshing the page, so whenever I put a button on the same page I need to press and release this button within 1 second else it gets refreshed. Also I saw that even outside of the UpdatePanel the timer isn't a real second. Any solutions?

  • Debugging ASP.NET on a built-in web server suddenly stops

    - by Anton Gogolev
    I have Windows Server 2008 (64-bit), VS 2008 with its built-in webserver and an ASP.NET MVC 1.0 webapp. All I'm trying to do is to debug said app. I have a bunch of breakpoints, but they behave in a very strange way. When I fist start a debugging session with F5 and hit a breakpoint, the debugger stops just fine. However, after serveral F10s/F11s debugging suddenly "stops" (no exceptions at that time), but neither VS detaches from browsers' process, nor webapp execution stops: Visual Studio stays attached, and web request continues executing as usual. I tried various browsers (Chrome, Firefox, IE), but to no avail. What do I do to solve this? It really drives me insane.

  • Programmatically adding a site to the Allowed Sites of the IE Pop-up Blocker (VB.NET)

    - by GlueR
    A few more details. I need to programmatically (Winforms, VB.NET) check if a site is in the Allowed Sites list of the IE Pop-Up Blocker (IE 7 and 8 and Windows XP, Vista and 7) and if not, add it. The application is fully trusted and I don't want to disable the Pop-Up blocker entirely. To clarify some things, this is for a web-automation application with several users across 3 countries. I want to avoid receiving tons of emails and explaining each time how to add the website to the Allowed Sites manually. Also, some of the users have Google Toolbar installed, which also has a Popup Blocker creating trouble to my app. Can this also be done programmatically?
