Configuration assistent failure

Posted By:      Posted Date: September 13, 2010    Points: 0   Category :SharePoint
Hello, we have a sharepoint 2010 trial installed and it works fine. Additionally I installed the Project 2010 Server on the machine. After installation you have to run the Configuration assistent and i get the following error message at step 8 of 11. I tried to find a solution in the internet but had no luck. "Fehler beim Erstellen von Beispieldaten" (Failed to create sample data) "Eine Ausnahme vom Typ 'System.NullReferenceException' wurde ausgelöst. Weitere Ausnahmeinformationen: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt." (An exception 'System.NullReferenceException' was thrown.

Getting "Provider load failure" from SSRS Configuration Manager (SQL 2008 R2 Hot Fix CU3 did not fix

After upgrading our SQL 2008 cluster to R2, SSRS on one node works fine, but the second node will not allow connection via the Configuration Manager (getting "Provider load failure").  We've done re-installs, repairs and applied Hot Fix CU3, but the issue remains. NOTE: It's understood that SSRS is not a clustered resource.  We have it installed as separate instances on each of the two cluster nodes.

ASP.NET Configuration not opening


I recently upgraded to VS 2010 and downgraded to SQL Server 2005. Now when I go Website > ASP.NET Configuration nothing happens.

It's likely this has to do with the fact that when I was installing SQL Server I got the 'ASP.net Version Registration requirement' warning, as well as the 'Failed to find the ASP.net Version Registration requirement with MS IIS'.

Anyone know what I need to get ASP.NET Configuration working?

An endpoint configuration section for contract 'xxx' could not be loaded because more than one end



I'm trying to test calling a webservice, I've found several free ones on http://webserviceshare.com, but none of them work for me.  Some of them give example calling code in C# which I've translated to VB.NET, they're typically just two to four lines, I don't think I've translated them incorrectly.

On that I've tried is US Zip Validator.  I added a Service Reference to http://www.webservicemart.com/uszip.asmx?WSDL, called ZipService.

I then call it like so:

            Dim myZipService As ZipService.USZipSoapClient = New ZipService.USZipSoapClient()
            Dim myCity As String = myZipService.ValidateZip("27707")

I get the following error on the first line of code:

"An endpoint configuration section for contract 'ZipService.USZipSoap' could not be loaded because more than one endpoint configuration for that contract was found. Please indicate the preferred endpoint configuration section by name."

A page with information on this web service (including C# source code) is at:

Configuration Tool


I'm fairly new to ASP.NET and I'm trying to think of the best way to implement my first dynamic website. I've noticed the ASP.NET Configuration tool and it seems quite useful but I have a few questions:

1. Can this page be accessed when the website goes live or is it best to make your own?

2. Can this tool handle custom SQL databases or must everything be built into the default one?

3. Can this tool be setup for local use initially and then changed for the hosting server details later on?

The website I'm build will have user account features, with a news and articles section which the user will be able to interact with. So I need to create a database to handle this. However I don't know whether to completely ignore this tool and just make everything custom or try and incorporate that into the ASP.NET Configuration tool. Also, if everything is made custom can you still use the membership tool in visual studio? Thanks for any help :) 

Customize failure text for login control


Hi all,

I would like to show the failure text in a client-side alert box for login control in c#. Please help me if there is an easy way to convert it from vb.net to c#.net. Thanks a lot!

Protected Sub Login1_LoginError(ByVal sender As Object, ByVal e As System.EventArgs) Handles Login1.LoginError
'Display the failure message in a client-side alert box
ClientScript.RegisterStartupScript(Me.GetType(), "LoginError", _
String.Format("alert('{0}');", Login1.FailureText.Replace("'", "\'")), True)

 End Sub

 Converted, but it doesn't work.

protected void Login1_LoginError(object sender, System.EventArgs e)
    //Display the failure message in a client-side alert box
    ClientScript.RegisterStartupScript(this.GetType(), "LoginError", string.Format("alert('{0}');", Login1.FailureText.Replace("'", "\\'")), true);

Error with ASP.NET Configuration Tool


I'm trying to make an MVC 2 site, and I've run into a bit of a snag.  I want to add user roles to my system via the configuration tool, but every time I click the Security tab I get the following error:

"There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store.

The following message may help in diagnosing the problem: Could not load type 'HandiGamer.MvcApplication'."

When I click on the 'Choose Data Store' button, it tells me I'm already using AspNetSqlProvider.

I have a .mdf file for the rest of the site's db, but didn't make any tables for membership as I thought all of that would be handled by the configuration tool.

Am I missing a step?
