In web project application just created I added some class to App_Code folder by means of Solution explorer.
It resides in the same namespace as the web project one.
But from default.aspx.cs I can not access that class reporting error that the object is not defined? but it is in the same namespace and should be visible as in C# projects.

App_Code\SomeClass.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IO;
namespace SomeNameSpace
{
        [Serializable]
        public class SomeClass
        {
                public SomeMethod { ... }
        }
}

default.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IO;
namespace SomeNameSpace
{
        public partial class _Default : System.Web.UI.Page
        {
                protected void Page_Load(object sender, EventArgs e)
                {
                        SomeClass sc = new SomeClass(); //<-- error
                  
                }
        }
}

Error: The type or namespace name 'SomeClass' could not be found (are you missing a using directive or an assembly reference?)

Try this.

First Create a class in App_Code,like the below

using System;
using System.Data;
using System.Configuration;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;

/// <summary>
/// Summary description for Class1
/// </summary>
public class Class1
{
	public Class1()
	{
		//
		// TODO: Add constructor logic here
		//
	}

    public string test()
    {
        return "Test";
    }
}

and create the object for that class in default.aspx.cs, like

Class1 cls = new Class1();

and call the function "Test" in default.aspx.cs

string str = cls.test();

Without any contructors when you type in SomeClass inside default.aspx.cs it is absent in the list of objects available.
Adding constructor does not help. Still the simple declaration of object is forbidden. It is not visible from .aspx.cs

Problem with membership provider DB created using ASP.NET configuration

14-Jul-09 21:01

I am using membership provider DB created using ASP.NET configuration. working fine on my machine.
I after deploying I get the below error when I click login button

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

I get Error 26 when I try to run a SqlCommand object referencing the same connection string, but the membership provider works properly.

Is that I need to install sql server on the server or .NET frame work will takcare of it,
I am new to ASP.NET programming/ deploying please help me

The membership provider DB will be stored in SQL Server. Therefore you need to have SQL Server in the deployed server. Also change your membership provdier connection string details accordingly in the web.config.

Hi,

calling SmtpMail.Send just passes the message to your smtp-server (localhost in your case). This doesn't say anything about if the mail was "physically" send to gmail. You have to check if your smtp-server has trouble sending the mail to gmail. Have a look in the queues of your smtp-server (can be found under inetpub). Then check for errors in the event log. It could also be that gmail doesn't allow that messages are sent to them by your smtp-server (for security reasons).

Let me know if you need some further help.

Regards
Sebastian

It's not a bug, it's a feature!

Hi All

I have a web application in asp.net 1.1 and sql server 2000, it was running alright previously, but for some weeks users are reporting that they are facing error.
In the application whenever any error comes , user is being redirected to an error page and the actual error message comes to our(the programmers) email.

The error message is very long but I'll mention the important part:-

In the email :-
System.NullReferenceException: Object reference not set to an instance of an object. at CBSolutions.ETH.Web.newlook.VSPage.LoadPageStateFromPersistenceMedium() at System.Web.UI.Page.LoadAllState() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

The code for function CBSolutions.ETH.Web.newlook.VSPage.LoadPageStateFromPersistenceMedium() is :-

protected override object LoadPageStateFromPersistenceMedium()
{
if (ConfigurationSettings.AppSettings["ServerSideViewState"].ToUpper() == "TRUE")
{
string VSKey;
VSKey = Request.Form["__VIEWSTATE_KEY"];
if (!(VSKey.StartsWith("VIEWSTATE_")))
{
throw new Exception("Invalid VIEWSTATE Key: " + VSKey);
}
if (ConfigurationSettings.AppSettings["ViewStateStore"].ToUpper() == "CACHE")
{
return Cache[VSKey];
}
else
{
DataTable VsDataTable;
DataRow DbRow;

VsDataTable = ((DataTable) Session["__VSDataTable"]);
DbRow = VsDataTable.Rows.Find(VSKey);
// if (DbRow!=null)
// {
// throw new Exception("VIEWStateKey not Found. Consider increasing the ViewStateTableSize parameter on Web.Config file.");
// }
return DbRow["VsData"];
}
}
else
{
return base.LoadPageStateFromPersistenceMedium();
}
}

Also in the Event Viewer application log, the following warning appears:-

Event code: 3005
Event message: An unhandled exception has occurred.
.
.
.
.
.
Thread information:
Thread ID: 6
Thread account name: NT AUTHORITY\NETWORK SERVICE
Is impersonating: False
Stack trace: at System.Web.HttpServerUtility.MapPath(String path)
at ETH.Global.Session_End(Object sender, EventArgs e)

Here ETH.Global.Session_End(Object sender, EventArgs e) is written in Global.asax which is as follows:-

protected void Session_End(Object sender, EventArgs e)
{
//clean up temporary files
string[] files = System.IO.Directory.GetFiles(Server.MapPath("Files/"),"WF-" + Session.SessionID + "*.*");
for(int i=0;i<files.Length;i++)
System.IO.File.Delete(files[i]);

Response.Redirect("default.aspx");
}

Also, the server has Windows Server 2003.Also some weeks back server was updated to Sql Server SP4.
Any help is appreciated.

Thanks
Raj

As the exception says,you must be eccesing some object that is not instantiated properly.So debug it and find which object is not getting created properly.

Cheers!!

Few companies that installed computers to reduce the employment of clerks have realized their expectations.... They now need more and more expensive clerks even though they call them "Developers" or "Programmers."
