ASP.Net problem
Hello,
I am new'ish to asp.net and I'm trying to connect to a MS SQL database with my provider who is 1and1.com.
When running my very simple asp page I get this error:
------------------------ BEGIN
Server Error in '/' Application.
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not load type 'HelloWebForms._Default'.
Source Error:
Line 1: <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.v b" Inherits="HelloWebForms._D efault" %>
Line 2:
Line 3: <!DOCTYPE html>
-------------------------- --------- END
the code in the default.aspx is like this:
Any ideas why this is happening and how I resolve it?
If you have a working example from 1and1 then I'd gladly take that as well.
Thanks

It's in the web.config file:
<connectionStrings>
<add name="FriendsConnectionStr ing1" connectionString="Data Source=dbxxxxx.db.1and1.co m;Initial Catalog=dbxxxxx;user id=dboxxxxx;password=xxxxx x" providerName="System.Data. SqlClient" />
</connectionStrings>

<connectionStrings>
<add name="FriendsConnectionStr
</connectionStrings>

Please post your code behind page or at least the top of it as the error seems to be referring to the fact it can't load the partial class defined in your Page declaration :
Inherits="HelloWebForms._D efault
Inherits="HelloWebForms._D
ASKER
Imports System.Data.OleDb
Imports System.Data.SqlClient
Imports System.EventArgs
Public Class _Default
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
End Sub
End Class
OK it is in the web.config however does your program read and sets it?
specifying connection string in the web.config is not enough. Your code should read it.

using ConnectionStrings:FriendsC onnectionS tring1 is how you read a connectionstring setup in the web.config.

Same error...

Is this a website or web application project, if it's a website project in your page declaration try changing :
CodeBehind="Default.aspx.v b"
to :
CodeFile="Default.aspx.vb"
CodeBehind="Default.aspx.v
to :

It's developed in visual studio 2012, I'm not sure I understand the difference between a web-app and a website?
I thought it was kind of the same, except a webapp typically connects to a database.
Please correct me...
I thought it was kind of the same, except a webapp typically connects to a database.

the main difference between web site projects and web application projects is that web application projects are precompiled before being published to the server whereas web site projects require all code files to be copied to the server which are then compiled by the server when they first get requested.
If it is a web application the project icon is rectangular window like icon and in the solution explorer just under the project folder should be a my project folder with an icon like a spanner.
If it is a web site project the project icon looks like a globe and in the solution explorer there will be a bin folder.
A web site project is created by selecting from the File menu in Visual studio, the New Web Site option.
A web application project is created by selecting from the File menu in Visual Studio, the New Project option and then selecting the appropriate Web Application template.
Both types of project can connect to a database and are very similar other than the fact the one is pre-compiled (web application) and the other is compiled on demand.
Web site projects where originally the only type of web project that was available prior to .net 2.0 framework, web application projects became available after the release of .net 2.0 framework.
To refer to the code-behind file in web applications use :
CodeBehind =
in web sites use :
CodeFile =

It seems I'm actually unable to connect using a web.config file with 1and1... POS :)
I'll do a little more research and reward points shortly.
tnx

Seems my internet provider doesn't let me fiddle with it...
thanks anyway!

Do that by testing in in code behind(VB file) instead of HTML file.
So:
1: put a button on the form
2: Add code the button so it defines a Sqlconnection and connection string and then open the connections.
Make sure above works. If it does work then you can add it to the HTML.
Also in your html you have:
ConnectionStrings:FriendsC
I don't see anywhere you have defined FriendsConnectionString1.
