AJAX :: Exception Error With Slideshow Service
Feb 1, 2010I have the following problem with a slideshow in Ajax. Hope I have put it in the right Ajax forum. Some info: I do use MS Access and in the 'autos table' i do have the following fields:
field 1: nummer (text field) - this is the name of the image
field 2: cat (integer) - this is the category of the cars
field 3: naam (text field) - this is the name of the car
field 4: model (text field - this is the model of the car
In my masterpage i do have a menu where you can make the choice of a certain category of cars. This is done by a call to: slideshow.aspx?cat=100 In Slideshow.aspx a panel is setup and also buttons to manipulate the found images. Also the AjaxToolkit:Slideshowextender is defined as follows:
<ajaxToolkit:SlideShowExtender ID="SlideShowExtender1" runat="server"
TargetControlID="Image1"
SlideShowServicePath="slideservice.asmx"
SlideShowServiceMethod="Getslides"
AutoPlay="true"
ImageTitleLabelID="Name"
ImageDescriptionLabelID="Desc"
NextButtonID="NextButton"
PlayButtonID="PlayButton"
PlayButtonText="Play"
StopButtonText="Stop"
PreviousButtonID="PrevButton"
PlayInterval="4000"
Loop="true"
ContextKey="catid" />
As you can see the contactkey is also defined.
Inside the codebehind of slideshow.aspx.vb their is a sub defined:
Partial Class Slideshow
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
SlideShowExtender1.ContextKey = Request.QueryString("catid")
End Sub
End Class
The call from slideshow.aspx is to a slideservice.asmx which contains:
<%@ WebService Language="VB" CodeBehind="~/App_Code/SlideService.vb" %>
Here we call slideservice.vb.
The coding of the slideservice.vb file is:

Dim sCatid As String = ""

cmd.Parameters.AddWithValue("@catid", sCatid)
Dim thisReader As OleDbDataReader = cmd.ExecuteReader()
Dim photoCounter As Integer
While thisReader.Read()
photoCounter = photoCounter + 1
End While
If (photoCounter > 0) Then
'we now know how many pictures there are in this category of the database
Dim MySlides(photoCounter - 1) As AjaxControlToolkit.Slide
'set up the command string
Dim photoLookupCmd As New OleDbCommand(SQLStr, cn)
'and add the parameters to it for the category
photoLookupCmd.Parameters.AddWithValue("@catid", sCatid)
thisReader = photoLookupCmd.ExecuteReader()
Dim i As Integer
For i = 0 To photoCounter - 1
thisReader.Read()
Dim number As String = thisReader.GetString(0)
Dim name As String = thisReader.GetString(1) + " - " + thisReader.GetString(2)
MySlides(i) = New AjaxControlToolkit.Slide(("pictures" + number + ".jpg"), name, "")
Next
thisReader.Close()
Return MySlides
Else
Dim MySlides(0) As AjaxControlToolkit.Slide
MySlides(0) = New AjaxControlToolkit.Slide("pictures99999.jpg", "sorry - not available", "pls. mail us to report")
thisReader.Close()
Return MySlides
End If
Catch x As Exception
Dim MySlides(0) As AjaxControlToolkit.Slide
MySlides(0) = New AjaxControlToolkit.Slide("pictures99999.jpg", "Exception error", "pls. mail us to report")
Return MySlides
Finally
cn.Close()
End Try
End Function
End Class
When i run the code i will get an exception error and when following the code in debug mode i do see that inside the first loop in FOR i = 0 to photocounter - 1 : The first loop gets the right info from the database inside Myslide(1) fields. Going into the second loop i will get after dim name as string .....
the program goes to catch x as exception. I did see that number was found correctly during the previuous line. During an other debug session i noticed that the Parameter.item has the following error (which I do not understand), saying: Overload resolution failed because no accessible 'Item´ accepts this number of arguments.

View 1 RepliesError - Module Not Found Exception From 2.0 Web Service On Windows Server 2008 R2
Sep 14, 2010We have an issue with a .NET 2.0 web service application that is generating a module not found exception when we try to load on server 2008. A second server running the same 2008 version loads the service fine.As part of the investigation we have taken the default hello world .NET 2.0 web service and deployed to both servers and have exactly the same issue with it running fine on one but not the other. The issue is trying to track down the module in question. Running process explorer and dependency walker doesn't seem to give us a clue.

Web Forms :: Redirect Custom Page While Error No 401.2 Occur
Nov 10, 2010I have developed .net web application. When i change the page name(Which is not exist) in URL, it throws following error msg. I could not redirect the error page for respected error no(401.2..) Through IIS Admin and web config. Could anybody give appropriate solution. It is urgent. Access is denied. Description:
An error occurred while accessing the resources required to serve this request. The server may not be configured for access to the requested URL. Error message 401.2.: You do not have permission to view this directory or page using the credentials you supplied.

Convert Exception Into HTTP 404 Response In Application Error
May 11, 2010First of all, quickly what exactly I want to achieve: translate particular exception into the HTTP 404 so the ASP.NET can handle it further. I am handling exceptions in the ASP.NET (MVC2) this way:
protected void Application_Error(object sender, EventArgs e) {
var err = Server.GetLastError();
if (err == null)
return;
err = err.GetBaseException();
var noObject = err as ObjectNotFoundException;
if (noObject != null)
HandleObjectNotFound();
var handled = noObject != null;
if (!handled)
Logger.Fatal("Unhandled exception has occured in application.", err);
}
private void HandleObjectNotFound() {
Server.ClearError();
Response.Clear();
// new HttpExcepton(404, "Not Found"); // Throw or not to throw?
Response.StatusCode = 404;
Response.StatusDescription = "Not Found";
Response.StatusDescription = "Not Found";
Response.Write("The whole HTML body explaining whata 404 is??");
}
The problem is that I cannot configure default customErrors to work with it. When it is on then it never redirects to the page specified in customErrors: <error statusCode="404" redirect="404.html"/>. I also tried to raise new HttpExcepton(404, "Not Found") from the handler but then the response code is 200 which I don't understand why. So the questions are:
1-What is the proper way of translating AnException into HTTP 404 response?
2- How does customErrors section work when handling exceptions in Application_Error?
3- Why throwing HttpException(404) renders (blank) page with success (200) status?
SQL Server ::error Occur Paste The Generated Query Into Sql Management Studio?
Aug 4, 2010I have been using a function that replaces some characters from my editor in asp.net with '+CHAR(x)+' to chain together a string with characters such as single quote that would otherwise break the query, i know how to escape the character using double single quote but i was wondering why i get this problem.The problem is that when the string gets too long about 7kb to 8kb its gets cut off for no reason, no error message gets displayed, the query is successful only the string cuts off at a point. When i escape the character without using '+CHAR(x)+' to add the character i can add a very long string that does not cut off,i am using Varchar(max) for my field, (have also tried text).I am using sql 2008 express edition, and encounter this problem when i paste the generated query into sql management studio, and when i execute the query fromasp.net code.

WCF / ASMX :: Return Dynamic / When Returns To Aspx Error At Aspx(no Exception Gets Caught At @ Service)?
Feb 9, 2011In our project WCF service is acting as our BLL.
i had scenario where i had to fill list of object class without knowing its type see code:
Added contract
[OperationContract]
dynamic GetReferenceTableData(string tableName);
method in service:
public dynamic GetReferenceTableData(string tableName)
{
try
{
dynamic tableData = ReferenceTableDAL.GetReferenceTableData(tableName);
return tableData;
}
catch (Exception ex)
{
throw;
}
}
method at DAL(ReferenceTableDAL):
public static dynamic GetReferenceTableData(string tableName)
{
Database db = DatabaseFactory.CreateDatabase(Flags.ConnectionStringKey);
DbCommand dbCommand = db.GetStoredProcCommand("USP_GETTABLEDATA");
dynamic objDynamic = null;
if (tableName.ToLower() == "a")
{
objDynamic = new List<A>();
}
else if (tableName.ToLower() == "b")
{
objDynamic = new List<B>();
}
else if (tableName.ToLower() == "c")
{
objDynamic = new List<C>();
}
try
{
db.DiscoverParameters(dbCommand);
dbCommand.Parameters["IN_TABLENAME"].Value = tableName;
DataSet dsTableData = db.ExecuteDataSet(dbCommand);
if (tableName.ToLower() == "a")
{
foreach (DataRow dataRow in dsTableData.Tables[0].Rows)
{
objDynamic.Add((A)dataRow);
}
}
else if (tableName.ToLower() == "b")
{
foreach (DataRow dataRow in dsTableData.Tables[0].Rows)
{
objDynamic.Add((B)dataRow);
}
}
else if (tableName.ToLower() == "c")
{
foreach (DataRow dataRow in dsTableData.Tables[0].Rows)
{
objDynamic.Add((C)dataRow);
}
}
}
catch (Exception ex)
{
throw;
}
return objDynamic;
}
@ Aspx
try
{
using (DataServiceRef.DataServiceClient petService = new DataServiceRef.DataServiceClient())
{
dynamic tableData = petService.GetReferenceTableData(tableName);
//tableData is null ,exception
}
}
catch (Exception ex)
{
throw;
}
There is no exception at dal or service end when i debug list gets filled ok but when returns to aspx error at aspx(no exception gets caught at @ service) but exception at aspx i.e:
Message:The underlying connection was closed: The connection was closed unexpectedly.

Show Authorization Error Message In MVC 2 Application?
Jul 10, 2010I'm using the Authorize attribute to filter controller actions based on user roles, but if an unauthorized action is attempted, the user is redirected back to the login page. As I user I would find this confusing and irritating. How can I instead show an error message informing the user they need certain roles, and remain on the view where they attempted an action?

Console Application Calling Datalayer Throws An Exception "The Type Initializer For Threw An Exception."
Aug 17, 2010I have simple 3 tier web application and have mostly CRUDE functionalities. Recently I required to add new console application to the existing solution in which I call data layer methods for retrieving data from DB but I get an exception "The type initializer for threw an exception."When I debugged I found that the exception is thrown at datalayer on first line of class where I get connectionstring from
web.config, the code is public static readonly string CONNECT_STRING =
ConfigurationManager.ConnectionStrings["DbConnectString"].ConnectionString;
Now if I hardcode the connection string value like public static readonly string CONNECT_STRING = "Data Source=XYZ;uid=sa;password=XXX;initial catalog=ABC;"
it works fine.I don't understand what is the issue here as web application works fine with this datalayer.
