  • How do I fix "error 1004, 0, Unable to find property" in an Entity Framework 4 WinForms application?

    - by Ivan
    I've designed an EF4 model (quite complex inheritance, lots of small tables incl. multiple self-referencing), generated (table-per-type) a database and inserted some basic data manually. It works fine in an ASP.Net Dynamic Data Entities web application with full automatic scaffolding. But when in a WinForms application using the same model (I share it as a part of a class library) I construct a query and bind a combo box to it (the way it's shown here), I get an InnerException {"Internal .NET Framework Data Provider error 1004, 0, Unable to find property... I've found a question about the same problem here (incl. a sample to reproduce the error) but no answer. I use final Visual Studio 2010, no beta.

  • Surely there is a better grid than DataGrid for the .NET Compact Framework...

    - by PavelR
    Having spent a couple of days wrestling with DataGrid in .NET CF, especially controlling the look and feel, I'm looking for alternatives. I don't mind purchasing a solution. I'm looking for Redistributable to our enterprise customers. We control the hardware so it doesn't have to work perfectly on every device. Display strings and numbers in columns with headings. Scrollable, but no paging. Don't row editing. Need to add and delete rows. User re-sizable column widths, and a way to persist that. Work with .NET CF 2.0 or 3.5 on Windows CE 6.0 Any suggestions on grids or toolkits?

    - by Glenn
    I'm working on this project and the customer wants it to integrate with a groupware package including bulk email, calendars, and task lists. He has heard about Horde and Horde GroupWare and is interested in using that. Do you have any developer related experience with Horde? If so, then what were your findings? Did you find it to be stable? What about the framework/API? Was it easy to integrate with?

  • ASP.NET + GoDaddy Free Hosting?

    - by Sahat
    Has anyone successfully been able to deploy ASP.NET website to GoDaddy's free hosting? I am talking about free hosting that comes with a domain package from GoDaddy. The catch of the free hosting is having an annoying Google Ads banner in a frame on top of the page. I've searched Google, stackoverflow and GoDaddy forums but I can't find anywhere the solution to my problem. When I upload a ASP.NET website to GoDaddy, it gives me an error - something about TrustLevel. Someone told me that by default asp.net websites have Full Trust Level which GoDaddy doesn't allow. I've even tried changing Trust Level to Medium manually, but with no luck. What may be the problem?

  • ASP.NET and SQL server with huge data sets

    - by Jake Petroules
    I am developing a web application in ASP.NET and on one page I am using a ListView with paging. As a test I populated the table it draws from with 6 million rows. The table and a schema-bound view based off it have all the necessary indexes and executing the query in SQL Server Management Studio with SELECT TOP 5 returned in < 1 second as expected. But on the ASP.NET page, with the same query, it seems to be selecting all 6 million rows without any limit. Shouldn't the paging control limit the query to return only N rows rather than the entire data set? How can I use these ASP.NET controls to handle huge data sets with millions of records? Does SELECT [columns] FROM [tablename] quite literally mean that for the ListView, and it doesn't actually inject a TOP <n> and does all the pagination at the application level rather than the database level?

  • Graph database for .NET

    - by Antonello
    I've been designing an application, based on .NET/Mono framework, which should make an heavy use of the shortest-path in a graph theories and I would like to use a native solution to traverse the nodes of the graph, instead of implementing surrogate solutions which would be hardly maintainable and would massively affect performances. I've found an application which would be perfect for my scope: neo4j. Unfortunately, this application is purely written in Java code and it's not portable to .NET, because of the massive differences between the two architectures. Is anyone out there knows if is it there any port of neo4j or a similar solution for .NET?

  • Converting MS Word Documents to PDF in ASP.NET

    - by glaxaco
    Similar questions have been asked, but nothing exactly like mine, so here goes. We have a collection of Microsoft Word documents on an ASP.NET web server with merge fields whose values are filled in as a result of user form submissions. After the field merge, the server must convert the document to PDF and stream it down to the browser. Our first inclination was to use the Visual Studio Tools for Office API; however, we ran into this warning from Microsoft: Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment. It looks like the field manipulation can be done using the Open XML SDK, but what's the best way to convert Word 2007 documents to PDF without opening Word? The optimal solution would be low-cost, scalable, have a low memory footprint, be easy to deploy, and have a .NET API.

  • Anybody Know of any Tools to help Analysing .NET Trace Log Files?

    - by peter
    I am developing a C# .NET application. In the app.config file I add trace logging as shown, <?xml version="1.0" encoding="UTF-8" ?> <configuration> <system.diagnostics> <trace autoflush="true" /> <sources> <source name="System.Net.Sockets" maxdatasize="1024"> <listeners> <add name="MyTraceFile"/> </listeners> </source> </sources> <sharedListeners> <add name="MyTraceFile" type="System.Diagnostics.TextWriterTraceListener" initializeData="System.Net.trace.log" /> </sharedListeners> <switches> <add name="System.Net" value="Verbose" /> </switches> </system.diagnostics> </configuration> Are there any good tools around to analyse the log file that is output?

  • ASP.NET application stopping event?

    - by Barguast
    I have a ASP.NET application which implements a custom in-memory cache. I'm using this as opposed to ASP.NET's caching mechanism as I needed a more complex way to handle what to drop from the cache. Part of this custom cache is a separate thread which occasionally searches for data to drop from the cache whenever it gets too large. What I need to do is signal this cache maintenance thread to stop whenever the ASP.NET application 'exits'. I guess this basically amounts to when the web site is stopped in IIS. Is there a pre-existing event I can utilise to do this? Thanks.

  • .NET Recaptcha https

    - by TygerKrash
    We've started using the ASP.NET recaptcha control and it works fine. but one of the requirements we have is that all outbound traffic goes over Https. I know that recaptcha supports https, but It's not clear how to configure (or even if it is configurable) when using the ASP.NET plugin option. has anyone got any experience of this? I'll expand a little on what I've found so far.... The Recaptcha package contains 3 public classes RecaptchaControl, RecaptchaValidator and RecaptchaResponse RecaptchaControl is an Asp.NET control, the recaptcha specific methods on there seem to be concerning themes/look and feel. An instance of the Validator has a RemoteIP field (which I presume would represent the verification server), but I can't a way of binding that to the control. RecaptchaResponse seems to more or less represent an enum with possible responses (valid/invalid/failed to connect).

  • Porting a PowerBuilder Application to .NET

    - by Justin Ethier
    Does anyone have any advice for migrating a PowerBuilder 10 business application to .NET? My company is considering migrating a legacy PB application to .NET (C#) and I am just wondering if anyone has any experience - good or bad - that you would like to share. The application is rather large with 10 PBL libraries, some PFC as well as custom frameworks. There are a large number of DLL calls being made as well. Finally, it uses a Microsoft SQL Server database. We have discussed porting the "core" application code to .NET and then porting more advanced functionality across as-needed.

  • How can I add a VS 2010 .Net 4.0 build agent to TFS 2008

    - by Mark Arnott
    My company has two development teams using TFS 2008. My team would like to migrate our .Net 3.5 app to the .Net 4.0 framework, but the company is not ready to upgrade TFS to TFS 2010. Can we still use TFS 2008's team build system but with a Visual Studio 2010 solution/project structure that targets the .Net 4.0 framework? I am thinking we would need to add a new build agent to TFS 2008 that would have VS 2010 installed. But I am not finding any information on how to do this. Is this possible? Are there any articles explaining how to do this?

  • Missing Project Template after installing ASP.NET MVC 2

    - by DotNetHacker
    Hi, I have downloaded the ASP.NET MVC 2 Release version (using Web Platform Installer) as well as the downloading the file directly from the link in WPI. No error messages are reported after the install. When I go into Visual Web Developer and select Create New project I only the project reference to ASP.NET MVC version 1.0 and not version 2 (for clarity I have all the other project types, this is just in reference to the MVC projects). I have restarted, uninstalled and restarted and installed my PC multiple times and it still won't play. When clicking add a reference I can see the MVC.dll version 2.0.0.0 and add that no problem, but cannot manually upgrade the project since the ProjectTypeGuid used is not recognized. For reference I am using Visual Web Developer 2008 on Windows XP. ASP.NET MVC version 1.0 is working fine and without issue. Hope someone else can help. DNH

    There are many asp.net web hosting companies which spends lot on advertisement and also gives you very cheaper rate, as low as $5, but when it comes to support they are simply hopeless.

Url Rewriter support GZip support (Dynamic through code) Initial Setup support (If required) SQL Server 2005 or 2008 Allow to access SQL Server DB using SQL Mgmt Studio Environment supporting Backup and Restore of DB on my own, without involving tech support team Full Text Search support FTP support I can able to send atleast 500 Emails daily. 99.9% Up Time (No matter all web hosting say they have 99.9% Up Time, but its not true). Alert Email to be sent when they do any maintenance or during downtime. Hosting Price should be reasonable. Incase you feel i am missing something please add to the list. Can anyone suggest good webhosting company based on above factors?
