I already have a piece of code that do almost all of the work, what i miss / unable to make it work is setting correctly the "Data Source".
The CSV file that I want to load is located on different server in the network (path is " d47vcpublicJoeASPTest").
Here is the code I wrote:

I get the following error:
'd47vcpublicJoeASPTest' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.

I have a ASP.NET (C#) web page in which I want to enumerate a dictionary in a code render block:

How do I import System.Collections.Generic into the page itself? Here is my page directive:

I have a C# web forms ASP.NET 4.0 web application that uses Routing for URLs for some reason custom errors defined in the system.web section of my web.config is entirely ignored and it will fall back the IIS errors.
This gets entirely ignored

This would be a minor inconvenience except that by the fact it falls back to IIS native instead of my application it completely circumvents Elmah logging my 404 exceptions correctly.

My base class file is a file called BaseClass.cs in my App_Code directory. Other functions in there work without errors. Why?
When I build my program, if there's one error that prevents it from running, instead of just getting the one error I'll get around 50 additional errors in addition to the real one such as:
Error 27 Validation (XHTML 1.0 Transitional): This name contains uppercase characters, which is not allowed.
Is there any way to not show these?

I am trying to publish an MVC 2 site in Visual Studio 2010 on Windows Server 2008 R2.
As I read to do, I expand References and select:
- System.Web.MVC
- System.Web.Routing
- System.Web.Abstractions and set Copy Local to True.
Then I right click the MVC Web Project and select Publish. I select Publish Method of File System. This publishes to the local file directory I specified in a compiled down version. My first question is this: The MVC specific references whose Copy Local I set to true do not show up in the published bin file like I thought they were supposed to do. Now when I copy the files over to production it does not work.
For the top level [URL] I get: 403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied.
For [URL] I get: 404 - File or directory not found. The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.
For [URL] I get: 500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed. Can someone point me to the right way to do this?

View 10 RepliesI have an application where I use the AJAX Tabpanel. It works 99 times out of 100. But sometimes a JavaScript error appears on the site saying that the Tabpanel cannot be found.
What I want is to check the site for JS errors and if JS errors appear then I will reload the site. In Pseudo-code:
Code:
If noJavaScriptErrorsAppear then
Ok
Else
reloadTheSite
Endif
Is that possible to implement in the serverside code e.g. in the page events?
I've developed a fairly simple web service which receives an xml string, validates it and passes it on to our internal database. This has been written to enable one of our clients to send us idocs from their SAP system. The trouble is that, although the web service works fine from a .net program, over the internet, the client's SAP system can't access it. They either get just an http 200 back (rather than the status code that the web service should supply) or they get http 500 'Internal Server Error'. I was wondering if anyone else has had issue's with ASP.NET web services from non 1qs`asp.net applications, or whether anyone can give me any advice on debugging http 500 errors.

View 2 RepliesWe are Running Windows 7 or Windows 2008 using integrated pipeline (not classic) and we are Getting 404 Errors when mixing MVC with Website and / or WebApplication ProjectsHowever, this problem doesn't exist when I run off the web server locally in visual studio, only when I use IIS 7.5. Is there anything special you need to configure in IIS 7.5 in order for website and webapplication projects to use MVC? I wouldn't think so, but when I run mvcapplication on IIS 7.5
