• How to stop .Net HttpWebRequest.GetResponse() raising an exception

  - by James

  Surely, surely, surely there is a way to configure the .Net HttpWebRequest object so that it does not raise an exception when HttpWebRequest.GetResponse() is called and any 300 or 400 status codes are returned? Jon Skeet does not think so, so I almost dare not even ask, but I find it hard to believe there is no way around this. 300 and 400 response codes are valid responses in certain circumstances. Why would we be always forced to incur the overhead of an exception? Perhaps there is some obscure configuration setting that evaded Jon Skeet? Perhaps there is a completely different type of request object that can be used that does not have this behavior? (and yes, I know you can just catch the exception and get the response from that, but I would like to find a way not to have to). Thanks for any help

• How do I locate a particular word in a text file using .NET

  - by cmrhema

  I am sending mails (in asp.net ,c#), having a template in text file (.txt) like below User Name :<User Name> Address : <Address>. I used to replace the words within the angle brackets in the text file using the below code StreamReader sr; sr = File.OpenText(HttpContext.Current.Server.MapPath(txt)); copy = sr.ReadToEnd(); sr.Close(); //close the reader copy = copy.Replace(word.ToUpper(),"#" + word.ToUpper()); //remove the word specified UC //save new copy into existing text file FileInfo newText = new FileInfo(HttpContext.Current.Server.MapPath(txt)); StreamWriter newCopy = newText.CreateText(); newCopy.WriteLine(copy); newCopy.Write(newCopy.NewLine); newCopy.Close(); Now I have a new problem, the user will be adding new words within an angle, say for eg, they will be adding <Salary>. In that case i have to read out and find the word <Salary>. In other words, I have to find all the words, that are located with the angle brackets (<). How do I do that?

• Telesharp – An Application Repository for .NET applications

  - by cibrax

  A year ago, we released SO-Aware as our first product in Tellago Studios. SO-Aware represented a new way to manage web services and all the related artifacts like configuration, tests or monitoring data in the Microsoft stack. It was based on the idea of using a lightweight SOA governance approach with a central repository exposed through RESTful services. At that point, we thought the same idea could be extended to enterprise applications in general by providing a generic repository for many of the runtime or design time artifacts generated during the development like configuration, application description or topology (a high level view of the components that made up a system), logging information or binaries. It took us several months to give a form to that idea and implement it as a product, but it is finally here and I am very proud to announce the release today under the name of “TeleSharp”. Telesharp provides in a nutshell the following features, 1. Configure your application topology in a central repository. Application topology in this context means that you can decompose your application and describe it in terms of components and how they interact each other. For example, you can tell that the CRM system is made up of a couple of WCF services and a ASP.NET MVC front end. 2. Centralize configuration for your applications and components.  You can import existing .NET configuration sections into the repository and associate them to the different components. In addition, environment overrides are supported for the configuration sections. We provide tooling and extensions in Visual Studio for managing all the configuration, and a set of powershell commands for automating the configuration deployment. 3. Browse all the assemblies and types remotely in your application servers in a web browser using an interface similar to any of the existing .NET reflection tools. You can easily determine this way whether the server is running the correct version of your applications. 4. Centralize logging and exception management into the repository. You get different reports and a pivot viewer experience for browsing all the different logging information generated by your applications. In addition, TeleSharp provides different providers for pushing the logging information to the central repository using well-known frameworks like ELMAH, Log4Net, EntLib or even Windows ETW.  The central repository itself is implemented as a set of OData services that any application can easily consume using regular Http. You can read more details in this introductory post If you think this product can be a good fit in your organization, you can request a trial version in our Tellago Studios website.

• Alternatives to CAT.NET for website security analysis

  - by Gavin Miller

  I'm looking for an alternative tool to CAT.NET for performing static security scans on .NET code. Currently the CAT.NET tooling/development is at a somewhat fragile stage and doesn't offer the reliability that I'm looking for. Are there any alternative static code analyzers that you use for detecting security issues?

• .Net User Messaging System

  - by bechbd

  I am wondering if there is a framework out there for .NET to help me with sending messages to users. I would love to be able to write all my messages to a single repository. I would then like to be able to send these messages out to a user based on preferences that they set. e.g. I would like to be able to send a Notification A out to user A via email and text message and send Notification B to user B via SMS and IM. Any thoughts on if something like this exists or would I need to write it?

• Authorize.net CIM or using the module's storage

  - by CQM

  this site is intended to allow users to sign up and pay for a service, they will be able to pay using Paypal and Authorize.net since I am using two different payment gateways, it makes me wonder where I want to keep the user information. Authorize.net offers CIM, but some users will pay with paypal therefore Authorize.net won't have all user's information Would the best solution then be to not use CIM and store everything within my member database module? for the record I am using OSE for Joomla for my subscriber service

• How do I deploy my ASP MVC project to my Win7 system?

  - by MedicineMan

  Hi, I am deploying my first ASP MVC project. The project runs just fine, I would like to take the next step and run this outside of my visual studio environment on my local IIS. I am running Windows7, Visual Studio 2008, and I have created a basic ASP MVC project. On my solution, I find the project I would like to deploy. I right click and select Publish. I have backed up C:\inetpub\wwwroot\ and would like to deploy there. I accept all defaults, and click the "Publish" button. The Output Build window shows 1 project failed. Basically is says that it is unable to add any of the binaries to the site, copy files, create new directories... Access is denied. When I do click "Publish" at work, I don't get these errors. What do I have to do here to publish the website to make the website available to the rest of my home network? Also wwwroot appears to be readonly, but telling the folder to not be read only doesn't seem to help, it still appears to be readonly even after I've unselected this property in the property dialog.

• 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!

  - by Dennis Larsen

  I was looking at this SO question: http://stackoverflow.com/questions/1168215/ado-net-entity-framework-update-only-certian-properties-on-a-detached-entity. This was a big help for me. I know now that I need to attach an entity before making my changes to it. But how can do I do this: I have an MVC website, a Customer Update Page with fields: ID, Name, Address, etc. My MVC is parsing this into a Customer entity. How do I do the following: Update my entity and Save the changes to it. Catch the exception if my changes have been made since I loaded my entity.

• Build an ASP.NET 3.5 Guestbook using MS SQL Server and VB.NET

  One of the most important website features is a guest book. This is particularly useful if you need to know the responses and reactions of your website s visitors. With the release of ASP.NET 3.5 and Visual Web Developer Express 2 8 several web controls make it possible to create an ASP.NET application without the need to hard manually code everything including database scripts server side scripts etc. You can see how that would be helpful to writing a guest book.

• .NET: Control Invoke() in Reflector

  - by sheepsimulator

  So, I was getting back into some .NET programming, and through a new feature in VS.NET 2010, it detected a case where I was trying to modify a control from a thread that didn't create that control, and pointed me to an article on MSDN about how you do this correctly... ' HOW TO WRITE TO A FORM CONTROL FROM A THREAD THAT DIDN'T CREATE THE CONTROL ' =========================================================================== ' Say you need to write to a UI text box that logs stuff... Delegate Sub WriteLogDelegate(ByVal [text] As String) Private Sub WriteLog(ByVal [text] As String) If Me.rtfLog.InvokeRequired Then ' We are not in the same thread! ' Create new WriteLogDelegate and invoke it on the same thread Dim d As New WriteLogDelegate(AddressOf WriteLog) Me.rtfLog.Invoke(d, New Object() {[text]}) Else ' We are totally in the same thread... ' Call AppendText like normal! Me.rtfLog.AppendText([text]) End If End Sub AND I WAS SO EXCITED BECAUSE I HAVE BEEN PUZZLED BY HOW TO DO THIS FOR LIKE 5 YEARS BECAUSE PREVIOUS VERSIONS OF VS.NET DIDN'T FLAG THIS SINCE I WAS AN UNDERGRAD ON A PROJECT AND... Umm... Sorry bout that. Composure regained. Anyway, now that I know this bit of .NET-fu, I'd like to learn more about what's going on and how it works. Where can I find the code for Invoke() in .NET Reflector?

• the best "Simple" CMS system suitable for .Net MVC

  - by Truegilly

  Hello, I'm developing a MVC .Net site and would like to implement a CMS system. So far I have looked at Umbraco, which looks good but the help is poor and the getting started video section is empty, and dotnetnuke, which again looks good but I get the impression its aimed at non developers, plus to has much more than I need and want. In my last job I created a basic custom CMS system that worked by simply adding values into the database, the application called the text from there. it worked fine but I don’t have the source code. what I'm after is a simple CMS system that really just controls text and images, I dont need all the fancy stuff thats in umbraco and dotnetnuke, all the design and CSS i can do myself. also as im working with MVC (which is awesome, and such a breath of fresh air compared to the web forms/telerik crap I have to put up with at work) it needs to be compatible. A simple CMS, can anyone provide any suggestion ? Truegilly

• why MVC instead of good old asp.net? Still not grasping why I should go this route??

  - by RJ

  I know this question has been asked before and I read all the answers but they still don't give me the answers I am looking for. I need something concrete. I volunteered to give a presentation on MVC to other developers in our group which forces me to learn it. The big question everyone has is: "What can MVC bring to the table that we can't do in asp.net or MVC can do faster. I have just gone through Nerd Dinner and actually created a complete website that sort of mimics Nerd Dinner. But as great a job that Scott Guthrie did on it, there are big gaps that aren't answered such as, how do I throw a textbox on the listing page with a button and do a simple search. In asp.net, I would throw a textbox, button and grid on the page and bind it to a sproc and away I go. What is the equivalent in MVC. I guess I need a really good tutorial on how to use MVC without using Linq-to-Sql. I know I am sort of babbling on about this but it is a very serious question that still seems to go unanswered. On a side note, the View page of MVC brings back nightmares of classic asp with all the in-line code that we got away from way back when with code behind pages. Yes, MVC has Controller and Model classes which are great but I still don't like the classic asp tags in the html. Help me out here, I really like the concept of MVC and want it to be successful but I need more!

• .Net 4.0 Is There a Business Layer "Technology" ?

  - by Ronny

  Hi, I have a theoretical question about the .net framework. As I see it Microsoft gave us bunch of technologies for different layers. We have the ADO.NET and with the more improved Entity Framework for Data Access. And ASP.NET for WEB UI. And even WCF for Facade and SOA. But what in the middle, what do we have for the Business Layer? Is it just Referenced DLLs? How do we deal with the Application Pulling this days? I remember using COM+ 10 yeas ago because the IIS couldn't handle the pressure. Is Spring.Net is the best option available for injection? Thanks, Ronny

• Game engine like Unity 3D that allow me to use .NET code

  - by Pking

  I've been looking at Unity 3D for developing a 3D PC game and I really like the scene editor and how it simplifies the process of constructing 3D scenes, managing assets, animations, transitions etc. However, I don't want to restrict myself to using the Unity 3D scripts for handling every bit of game logic in the game. E.g. If I want to construct a RPG dialogue system I don't want to do it with unity 3d scripts - I'd like to use C#/.net. Also, I might want to use e.g. windows azure and sql azure as backend, and use 3rd party .net libraries such as reactive-extensions etc. Is there a .net engine out there that helps me with asset loading, animations, physics, transitions, etc. with a scene editor, but allow me to plug it into a visual studio .net project? Thanks

• Pass Parameter to Subroutine in Codebehind

  - by Sanjubaba

  I'm trying to pass an ID of an activity (RefNum) to a Sub in my codebehind. I know I'm supposed to use parentheses when passing parameters to subroutines and methods, and I've tried a number of ways and keep receiving the following error: BC30203: Identifier expected. I'm hard-coding it on the front-end just to try to get it to pass [ OnDataBound="FillSectorCBList("""WK.002""")" ], but it's obviously wrong. :( Front-end: <asp:DetailsView ID="dvEditActivity" AutoGenerateRows="False" DataKeyNames="RefNum" OnDataBound="dvSectorID_DataBound" OnItemUpdated="dvEditActivity_ItemUpdated" DataSourceID="dsEditActivity" > <Fields> <asp:TemplateField> <ItemTemplate> <br /><span style="color:#0e85c1;font-weight:bold">Sector</span><br /><br /> <asp:CheckBoxList ID="cblistSector" runat="server" DataSourceID="dsGetSectorNames" DataTextField="SectorName" DataValueField="SectorID" OnDataBound="FillSectorCBList("""WK.002""")" ></asp:CheckBoxList> <%-- Datasource to populate cblistSector --%> <asp:SqlDataSource ID="dsGetSectorNames" runat="server" ConnectionString="<%$ ConnectionStrings:dbConn %>" ProviderName="<%$ ConnectionStrings:dbConn.ProviderName %>" SelectCommand="SELECT SectorID, SectorName from Sector ORDER BY SectorID"></asp:SqlDataSource> </ItemTemplate> </asp:TemplateField> </Fields> </asp:DetailsView> Code-behind: Sub FillSectorCBList(ByVal RefNum As String, ByVal sender As Object, ByVal e As System.EventArgs) Dim SectorIDs As New ListItem Dim myConnection As String = ConfigurationManager.ConnectionStrings("dbConn").ConnectionString() Dim objConn As New SqlConnection(myConnection) Dim strSQL As String = "SELECT DISTINCT A.RefNum, AS1.SectorID, S.SectorName FROM Activity A LEFT OUTER JOIN Activity_Sector AS1 ON AS1.RefNum = A.RefNum LEFT OUTER JOIN Sector S ON AS1.SectorID = S.SectorID WHERE A.RefNum = @RefNum ORDER BY A.RefNum" Dim objCommand As New SqlCommand(strSQL, objConn) objCommand.Parameters.AddWithValue("RefNum", RefNum) Dim ad As New SqlDataAdapter(objCommand) Try [Code] Finally [Code] End Try objCommand.Connection.Close() objCommand.Dispose() objConn.Close() End Sub Any advice would be great.

• How do I pitch ASP.NET over PHP to a potential client?

  - by roman m

  I work at a Microsoft shop doing mainly web development. We had a client who asked us to review (improve) the data model for his web app, but said that he wants to develop his app in PHP (he knows "a guy" who can do it). When I asked him why he wants to go with PHP, he gave me the standard set of arguments from the 90's: Microsoft is evil, and PHP is free Writing an ASP.NET app is more expensive (software-wise) Why would Facebook use PHP if it was a bad idea? [classic] He had a few more comments about the costs associated with going .NET. The truth is that "Microsoft is expensive" does not hold water any longer, with their "Express" suite, you can develop an ASP.NET app without paying anything for software. When it comes to hosting, you can save a few bucks with PHP over .NET, but that's a small fraction of the projected development costs (we quoted 10-15k). Going back to my question, what arguments would I give to a client in favor of ASP.NET over PHP? [please provide sources for quantitative claims]

• What tasks aren't easy for PHP, ColdFusion and ASP?

  - by boost

  PHP, ColdFusion, and ASP (among many others) are usually sold on their strengths. What are their weaknesses? If one were to develop a niche product to handle the things that these products weren't so good at, what should it focus on? EDIT I'm trying to figure out what things PHP etc are bad at. They're all good at doing the nuts and bolts stuff, if one is looking with a bottom-to-top mindset. I'm thinking a little more globally, more top-to-bottom; what's difficult to achieve in PHP/ASP/CF without thousands of lines of code and twenty minutes of server time? EDIT Suppose company A comes up to you and says, "We want you to do x in PHP." What values of x will cause you to say, "Forget it, buddy, no one in their right mind would use PHP for that"? (swap PHP in the above quote for your favourite tool) EDIT Have we got to the point where everyone's needs can be met with PHP frameworks, Rails and ... er ... Java?

• ASP.NET design not SOLID

  - by w0051977

  SOLID principles are described here: http://en.wikipedia.org/wiki/SOLID_%28object-oriented_design%29 I am developing a large ASP.NET app. The previous developer created a few very large classes each with lots of different purposes. It is very difficult to maintain and extend. The classes are deployed to the web server along with the code behind files etc. I want to share a small amount of the app with another application. I am considering moving all of the classes of the ASP.NET web app to a DLL, so the small subset of functionality can be shared. I realise it would be better to only share the classes which contain code to be shared but because of the dependencies this is proving to be very difficult e.g. class A contains code that should be shared, however class A contains references to classes B, C, D, E, F, G etc, so class A cannot be shared on its own. I am planning to refactor the code in the future. As a temporary solution I am planning to convert all the classes into a single class library. Is this a bad idea and if so, is there an alternative? as I don't have time to refactor at the moment.

• How can I serialize this .NET Collection item?

• Using an IN clause in Vb.net to save something to the database using SQL
