Can't access App_Code class in Code Behind file

  

I have a class defined in the App_Code subdirectory:

namespace WebApplication9_App_Code
{
  public class Class1
  {
  }
}

And I have a code behind class default.aspx.cs:

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

namespace WebApplication9
{
  public partial class _Default : System.Web.UI.Page
  {
    protected void Page_Load(object sender, EventArgs e)
    {
      WebApplication9_App_Code.Class1 cls1;
    }
  }
}

I get the following compilation error:

The type or namespace name 'WebApplication9_App_Code' could not be found (are you missing a using directive or an assembly reference?)

What am I doing wrong? 

Thanks very much for your help.


Access to report file denied. Another program may be using it.

  

Migrated from Windows 2000 ASP.NET 1.1 to Windows 2003, ASP.NET 2.0 and had this error. All the forums/MSDN/Blogs says to give Read/Write Access to C:\Windows\Temp folder. Why should we give Full Access to some folder in Production server?? In windows 2000, ASP.NET 2.0 development machine, no files are created when we run crystal reports from aspx pages. Then why in Windows 2003 servers, we need to give rights to temp folder?? It is a simple code

crReportDocument.Load(Server.MapPath("Project.rpt"));

And the code is not storing anything on the disk. Then why should it store the GUID.rpt file in Temp file in Windows 2003 server?? Any alternative is there not to store anything on the disk when Crystal Reports are opened in aspx page??

 


Make sure that the class defined in this code file matches the 'inherits' attribute, and that it e

  

Here is the page directive for the page that throws the error:

<%
@ Page language="c#" Inherits="University.AspNet.Index" CodeFile="Index.aspx.cs" %>

The code behind file Index.aspx.cs starts like this:

using University.Framework.UI;

namespace University.AspNet

{
      
public partial class Index : University.Framework.UI.HomePage

The code behind is extending this HomePage class, which is in turn an extenstion of another class University.Framework.UI.Page, which extends the System.Web.UI.Page class.

Asp.Net upload file access denied

  

Hi,

I have the problem below, if anyone can help me, appreciate it.

Server Error in '/' Application.


Access to the path 'c:\Inetpub\EnewsAttFiles\employ-e-header2.jpg' is denied.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: Access to the path 'c:\Inetpub\EnewsAttFiles\employ-e-header2.jpg' is denied.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Hig

How do I find the file path from a namespace.class name?

  

I'm programatically looking ito a .aspx file and getting the file class name declared in its CodeBehind. For example, when analyzing myFile.aspx I read in its Page Directive and found its CodeBehind equals "myApplication\myPage.aspx.vb". Then I use the code below:

 

Dim Assm As System.Reflection.Assembly = System.Reflection.Assembly.LoadFrom("myApplication\bin\myApplication.dll")
Dim ClassType As Type = Assm.GetType("myApplication\myPage.aspx.vb")
    
' myBaseType = "myApplication.Forms.BasePage"
Dim myBaseType As System.Type = ClassType.BaseType

 

Now I want to read the BaseFile (class = myApplication.Forms.BasePage). However, to read in this file, I need I need to get its full path instead of its namespace.class hiearchy. In this case, the BasePage is wrapped in a different namespace declaration thus I cannot just change the '.' to '\' in order to get the path.

How can I get the path of BasePage so I can read it? Thank you - Frank

How can I retrieve the correct resouce file (according to the current culture) from the business layer, and returning a List of KeyValue pair from it?

Thank you.

File Stream Class

  
 I am trying to write to a text file while protecting it from concurrent access. What is the advantage of fileStream.lock ? (when I created a filestream in the code below, the file seemed to be protected from other processes using it). I am not sure if I need to use filestream.lock below. Please advise ..            Public Shared Sub writeToLogFile(ByVal logMessage As String)         Try             Dim strLogMessage As String = String.Empty             Dim strLogFile As String = System.Web.HttpContext.Current.Server.MapPath("~/Log.txt")             Dim swLog As StreamWriter             strLogMessage =  DateTime.Now.ToLongTimeString().ToString() & " ==> " & logMessage             Dim fileStream As New FileStream(strLogFile, FileMode.Append)            ' Lock all of the file after creating the filestream object             fileStream.Lock(0, fileStream.Length)      &nb

Access to path xxx denied when uploading a file using c#

  
Hi I have a file upload app written in c#. The app runs on IIS on a Windows 2003 Server OS. I want the app to upload the file onto the server (The app and the server are on the same machine). This code has been working fine for a long time running on Windows Server 2000, and Windows XP Professional. Now when I moved onto Windows Server 2003, it stopped working. I have given ASPNET account full access to the folder on the server, and it still gives this error. Is this a bug in 2003, and can anybody assist me? Thanks Shane

How to get a file path in a class library used by asp.net

  
 Hello,   I have an asp.net application which employs a class project to process xml files. I have an xsd file within the class project. To load the xsd file, I am not sure which path I should use. The following code snippet loads the xsd, and reads the xsd using the StreamReader. I am not sure how to set the value for xsdPath variable.// 2- Read Schema file content StreamReader SR = new StreamReader(xsdPath); // 3- Create a new instance of XmlSchema object XmlSchema Schema = new XmlSchema(); // 4- Set Schema object by calling XmlSchema.Read() method Schema = XmlSchema.Read(SR, new ValidationEventHandler(ReaderSettings_ValidationEventHandler)); Thanks
