• web.config overrides app.config...why?

  - by vikp

  Hi, I have to DLLs: one with a web.config, another one with app.config I moved the connection strings from web.config to app.config so that it can be used by other DLLs. Now, when I call ConfigurationManager.GetSection("SomeSection") , the application looks for a web.config, when it should be looking for the app.config. It doesn't make sense why it does it because web.config is in a separate DLL. Can anybody explain this please?

• Calling web services from your JSF code

  - by Abel Morelos

  Let's say that you have a presentation tier in JSF, and that your business tier is accessed using web services. How would you call your web services from JSF? I was considering to have my backing beans to call the web services, but I just though I could use Ajax with JSF in order to connect to the web services. What would you choose and why? Any other choice you could recommend? Thanks.

• Web Deployment Projects tool and Web application project

  - by SourceC

  Hello, Q1 - As far as I know, Visual Studio doesn’t use aspnet_compiler.exe when compiling web application projects. And since Web Deployment Projects (WDP) tool is only used for manipulation the output created by aspnet_compiler.exe, I don’t understand how VS 2008 also has an option for using WDP with web application projects?! Q2 - What is a stock project? thanx EDIT: So I was right about the fact that Visual Studio doesn’t use aspnet_compiler.exe when compiling web application projects? much appreciated

• How do I set a single virtual directory of my web app to not inherit web.config?

  - by Ryan

  I have a virtual directory setup in one of my web apps that needs to not inherit the web.config of the main app so it can run on it's own. I am wondering how I can do this because right now when I hit it (mainwebapp.domain.com/virdir) it throws an error saying it can't find some dependencies that are listed in the main apps web.config (shows main app web.config in the error message), this virdir contains it's own little app that needs to just run standalone.

• How to add a reference to my Web Service Proxy from a Custom Class

  - by coffeeaddict

  I'm creating a custom class to abstract out some of the repeated SOAP header work. I want to reference a Web Service Reference I just created in my custom class so I can create an instance of it. How do I reference it? Notice I said I am trying to reference a Web Service "reference" (right click in VS and I added a "Web Service Reference" not a "Web Service"). So I'm trying to create an instance of that Proxy class that was created in MyCustomClass.cs

• Restoring web reference in Visual Studio 2008

  - by Mark Cheeseborough

  I had a web reference set in my VS2008 ASP.NET project, but due to some source control weirdness it is no longer listed in the project. I have the set of files in the Web References folder under my project. There's a .wsdl, .disco and several .datasource files. Is there any way to re-add this web reference through the existing files rather than using the "Add Web Reference" dialog?

• Designing a web service to be called by another language

  - by CollegeProgrammer

  This will sound naive (but then I am a junior programmer), but if I write a web service say in Python (standard WSDL web service), I then need to host it so it is reachable from an end point. This will give a URI for the service and then from another language, say Java or VB.NET (any), I can add a web service (this one) and then call the web service's object model, correct? Thanks

• Automatically inserting new fields in a web.config file

  - by MarceloRamires

  I have an ASP.NET project which has already some custom fields in it's web.config file. I've added in it three more fields and used them in my changes, and it's working great. But where it needs to be used, there aren't these thre fields in the web.config (this was expected, I've just added by hand for tests and developing). How do I check the existance of fields in web.config, and in case of not finding it, how do I add it permanently to the web.config ? Thank you

• Got an idea for an application, but part of it is patented, any suggestions?

  - by tekiegreg

  Hi there, so I've been working on developing an idea for an application that I think has the potential to be successful, however after some initial research I've discovered that at least part of my ideas are covered by a patent out there, the patent in particular is held by a really large company (I don't want to give away specifics for fear I'd draw their attention for sure). I'm debating a few options: 1) Develop patents around my ideas that don't conflict and maybe approach the company in question for a license exchange 2) Just approach them for a license outright 3) Just develop around it anyways and hope for the best :-p What have other people done in these situations? Are companies generally willing to grant patent licenses? Are they willing to grant them at reasonable prices? Thoughts?

• Can it be useful to build an application starting with the GUI?

  - by Grant Palin

  The trend in application design and development seems to be starting with the "guts": the domain, then data access, then infrastructure, etc. The GUI seems to usually come later in the process. I wonder if it could ever be useful to build the GUI first... My rationale is that by building at least a prototype GUI, you gain a better idea of what needs to happen behind the scenes, and so are in a better position to start work on the domain and supporting code. I can see an issue with this practice in that if the supporting code is not yet written, there won't be much for the GUI layer to actually do. Perhaps building mock objects or throwaway classes (somewhat like is done in unit testing) would provide just enough of a foundation to build the GUI on initially. Might this be a feasible idea for a real project? Maybe we could add GDD (GUI Driven Development) to the acronym stable...

• Development on Windows 7; Web server on Linux - How to share Apache web root?

  - by TheKeys

  I've got a LAMP server that I want to use as a local web server. I've got a Windows 7 machine that I want to use as my development machine. The machines will be on the same LAN (or the Windows box will be VPNed into the LAN). My questions is, what is the best way of sharing the web root of the LAMP server so that I can edit the files on the remote Windows 7 machine and how do I go about configuring this on the Linux machine? (Fedora 16) I would like the solution to be as easy to use as possible with preferably no extra steps required to save/edit/upload files from my IDE on my Windows 7 machine. I'm thinking either a Samba or NFS share are the way to go but I'm concerned I'm going to run into issues with permissions and unix/windows file handling. Is one better than ther other for my use case or is there a better alternative solution? I'm currently using Windows 7 Professional which doesn't have NFS support but would upgrade to Ultimate which does have NFS support if it's the best solution.

• Tracking down the cause of a web service fault running in IIS

  - by BG100

  I have built a web service in Visual Studio 2008, and deployed it on IIS 7 running on Windows Server 2008 R2. It has been extensively tested, handles all errors gracefully and logs any uncaught errors to a file using log4net. The system normally runs perfectly, but occasionally (2 or 3 times a day) a fault occurs and screws up the application which needs an iisreset to get it working again. When the fault occurs I get some random errors that are caught by my catch-all error log, such as: Value cannot be null. Could not convert from type 'System.Boolean' to type 'System.DateTime'. Sequence contains no elements These errors are raised on every request until I manually do an iisreset, but there is no sight of them when the system is running normally. The web service is a stateless request-response application. Nothing is stored in the session. It could be load related, but I doubt it as there are only around 30 or 40 requests per minute. This is proving very tricky to track down. I can't work out what is putting IIS into this bad state, and why it needs an iisreset to get it working again. Nothing is reported in the event log. Can anyone suggest how to enable more extensive logging that might catch this fault? Also, does anyone know what might be causing the problem?

• Copy a website and preserve the file & folder structure

  - by DrStalker

  I have an old web site running on an ancient version of Oracle Portal that we need to convert to a flat-html structure. Due to damage to the server we are not able to access the administrative interface, and even if we could there is no export functionality that can work with modern software versions. It would be enough to crawl the website and have all the pages & images saved to a folder, but the file structure needs to be preserved; that is, if a page is located at http://www.oldserver.com/foo/bar/baz/mypage.html then it needs to be saved to /foo/bar/baz/mypage.html so that the various Javascript bits will continue to function. None of the web crawlers I've found have been able to do this; they all want to rename the pages (page01.html, page02.html etc) and break the folder structure. Is there any crawler out there that will recreate the site structure as it appears to a user accessing the site? It doesn't need to redo any of teh content of the pages; once rehosted the pages will all have the same names they did originally so links will continue to work.
