Asp.net - IIS7 Automatically Redirect To Null (in IE)?
May 10, 2009
I'm developing an ASP.NET web site with VB. My web site is work perfectly with Firefox. But, with IE, it's redirect automatically to null.
When I try http:[url]....
IE6/IE7 automatically redirect to
http://localhost/mysite/null
But, there is no problem with pages inside sub folders. When I try with http:[url]....It's work perfect. I just can't browse pages in root folder. What should I do? I'm using IIS7 and .net framework 2.0.
I get the following error when I try to access a asp.net application on my local machine.HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid.
Module IIS Web Core Notification BeginRequest Handler Not yet determined Error Code 0x80070021
I need blog software for IIS7 and a SQL Server 2008 backend. I don't know if this is required, but the application (website) I'm hosting is in asp.net (vb.net). I checked out das blog, and graffiticms and they're very old.
I have written a generic file serving handler in asp.net/vb.net..I recently moved to a windows 7 box and am now debugging under IIS7, and this is where the problems occure.Whenever I serve a file to either FireFox or Chrome (IE8 works fine) from IIS 7, the download will fail.
- In FireFox the error is "[some file name and path].part could not be saved, because the source file could not be read."
- In Chrome the error is "Error 330 (net::ERR_CONTENT_DECODING_FAILED): Unknown error."
- In IE8 it works fine
If I run the same code in IIS6, it works fine.If I run the same code in the Visual Studio virtual web server, it works fine (on windows 7 or XP).I am rather concerned about this as our production web server will soon be IIS7; which I'm starting to really love, and would hate to revert to IIS6 just because this won't work in IIS7.I've tried a number of different patterns.It seems to always fail on the Flush() line with the error "System. Web.HttpException = {"The remote host closed the connection. The error code is 0x8007 0040."}"One thing I have noticed, if I move the flush statment to the finally clause or remove it all together; firefox will attempt to read the entire file - it appears to be looping through the entire block of code just fine, until it hits the flush statement.If I remove the flush statment I still get an error and it still tries to read the entire file before asking me to save it.[code]
Every time I start a new session of Internet Explorer, the web application prompts me for my Active Directory Username and Password instead of automatically retrieving that information from the currently logged in Active Directory profile.
How do I setup Single Sign On in the web config or default.aspx.vb file code-behind so that it doesn't prompt me for my active directory credentials? [code]....
I'm trying to write a simple load tester for one of our web services, which is served through IIS7. I'm launching a load of threads (as Tasks) that call the web service as a Web Reference.Despite the threads all starting, only 2 concurrent connections from the app can be handled by the web service. I'm aware that by specification simultaneous connections are limited to 2 per user. For the sake of this load tester, which I guess is one user, I would like to open many simultaneous connections.I have tried to add the following to the web.config of the web service.
The web service is located at [URL], where MyWebServiceApp is configured as an application.The webmethod can be viewed as something trivial that simply waits for, say, 20 seconds before returning a response (making it easy to see that only 2 connections are open at any one time).The simplest form of the load tester code is ass follows:
Imports System.Threading.Tasks Module SuperBasicLoadTester Sub Main()
[code]....
I've tried pointing other load testing software (e.g. soapUI) at the web service and have observed the same issue.
Edits: I should add that the web service box is running Windows 2008 R2.Also I have run SoapUI and my loadtester simultaneously and each is only able to request 2 connections each (i.e. 4 in total).
Background: I have an application that loads marketing companies into a drop down list if the currently logged in user is a member of that marketing group in active directory. The Group ACOMP_USER_BIG is compared to MarketingCompanyShortName Big in the database records via a web service. Problem: I have 3 Newly added AD Groups that won't load in production but load fine in the drop down on my local dev server. The deployment guy already tried doing an IISReset and that didnt fix the issue. All the AD groups have read access only and no write access. We need to find out more information on why the marketing company AD groups are not loading. How do I get the groups to load correctly or prove that the problem is not a programming issue and a deployment or AD issue? H*ere's the VB.NET Code behind that populates the marketing company drop down list.
Private _PurchaseDelivery as PurchaseDelivery Protected Overrides Sub InsertItem(ByVal index As Integer, ByVal item As PurchaseDeliveryItem)
[Code]....
Which is inside a class which overrides a custom list base. The code is occassionaly throwing an unhandled exception, System.NullReferenceException, on this line when used in production:
If _PurchaseDelivery IsNot Nothing AndAlso _PurchaseDelivery.DefaultSKUBinID.HasValue Then
DeafultSKUBinID is declared as an Integer? (Nullable Int) in the PurchaseDelivery class. I cannot see what might be causing this error, why would this be returning an error?
When I put a break point to the last if clause in the sub ("If (backOrder < 0) Then", see below) it runs until the break point, if I put the break point further below, I get the following error:
Cannot insert the value NULL into column 'OrderID', table 'WHM.dbo.OrderDetails'; column does not allow nulls. INSERT fails. The statement has been terminated.
I've discovered first hand that it only happens when prodqty is bigger then qtyOnStock, thus executing the if clause.
The code:
Private Sub NCOSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NCOSubmit.Click Dim sqlText As String = ""
I am trying to create a treeview in VB.net, the data has to be loaded from MSAccess 2010 database. When I try to run this program I get error : Argument Null Exception was unhandled, 'column' argument cannot be null and the program crashes. I have pasted the code as under:
Imports System.Data.OleDb Public Class frmRating Private Sub frmRating_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles
I need to redirect my page based off of the ID that was just created.This is my insert statement that generates the ID that I will need to fetch for the redirect.
'SQL Insert: Product table Dim sqlInsertProduct As String = "INSERT INTO Product (ProductName, Status, CreateDate, ModifyDate, CreateUser, ModifyUser, Price) VALUES (@ProductName, @Status ,getdate(), getdate(), @CreateUser, @ModifyUser, @Price)
[Code]...
The Response.Redirect is all the way at the bottom of the page after 3 other inserts into 3 different tables. The only thing I can think of to make this work is to put the redirect into that using, but I can't because I need the other tables to get inserted into and it wouldn't make sense to redirect before the rest of the inserts.
Protected Sub Login1_Authenticate(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.AuthenticateEventArgs) Handles Login1.Authenticate Dim Uname As String Dim pwd As String
[code].....
the code kis working without any errors . It is not redirecting to another page.
I havea a UserControl1 (in witch I have an Label1) in Form1. I want to catch the MouseDown event from Label and send it like it was from UserControl.I do:
Public Class UserControl1 Shadows Custom Event MouseDown As MouseEventHandler AddHandler(ByVal value As MouseEventHandler) AddHandler Label1.MouseDown, value
[code]....
One detail.. I want that the event should be only on the label, not on the whole userControl.
I have a GUI that contains several components (combo boxes, textboxes, etc) with their associated labels. When a button is pressed, the selection in each input component is validated, and if found to contain an invalid value, the label color changes to red and an error message appears. This works fine on its own.The problem arises when invalid values are provided and then later fixed. When the user presses the button and the inputs are valid, I redirect the response to an asp using Response.Redirect, which then runs and opens a PDF report. When this happens, none of the code to change the labels back to their original color or to remove the error message runs. If I change Response.Redirect() to Server.Transfer() and the user goes back, it returns the page to its original state (removing the error messages), but I want to keep the valid data in each component.
What can I do to either remove the error messages when the user goes back or to retain the valid input from the user?Most of the controls are non-standard .NET controls and I'm working with VB.NET 2003.
Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs) Dim exc As Exception Dim readdInfo As New NameValueCollection
[Code]....
But when i try to run above program i am getting Context.CurrentHandler is null exception. If i keep Response.Redirect in place of Server.Transfer I am getting 301 header. I've used [URL] for header checking
My loging page in root/Account/Login.aspx page when I click on contact us i need to redirect to root/contactus.aspx page. I used Response.Redirect("~/contactus.aspx") in Master page (Site.Master) Protected Sub lbContactUs_Click(sender As Object, e As EventArgs) Handles lbContactUs.Click
In my ASP.NET page I have a thread that runs for a while (sometimes up to 2 mins). How could I reload/ redirect the page after the thread is done? I know I can't use Response.Redirect() because the page is already done loading.
Im trying to set my homepage on my browser , i know i can do it in properties but that seens to revert back to the hompage that im using on IE.Heres my home button click
Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).GoHome() End Sub
What code do i need to add to redirect it to a certain webpage?
I am using the following code to try and redirect to https, it is not working.

What I can check, using fiddler now to look at traffic. SSL is set in IIS 6, cert is correctly installed on site.
I am using VB in VS 2008. I am tring to call an external process and redirect the input, and pars the output back to my code.I started with the useal
Dim myProcess As New Process() Dim StringFromProcess As String myProcess.StartInfo.WorkingDirectory = (path & "in")
[code]....
but I will need 4 of them to get to the data and it seem to me its messy coding. Is there a way to get ReadToEnd to work when reading data over TCPIP? Or perhaps a different/better way to read back from my process?
i'm creating a simple wpf browser application in vb.net.. my current problem is i don't know how to redirect a page using a hyperlink, being a newbie in the language.[code]
