Configuration :: Error When Creating Object From ASP
Apr 15, 2010
We have a website in ASP where we are having a series of errors when creating objects. We've created a number of DLLs with .NET, marked to be compatible with COM+. We have registered them on the system using the "regasm" utility from .NET with the parameter "/codebase". So far everything is fine, the problem comes when creating an object from ASP e.g: set objFoo = CreateObject("DLL.NET_COM_Compatible) That's when the error randomly jumps
Server object
ASP 0177
-2147418113
Server.CreateObject Failed
8000ffff
The error always jumps on any page where you make a "set". At first doesn't give errors but at some point it starts to happen and in order to stop it we have to restart IIS and sometimes even the machine. This has begun to occur more often after a significant increase in visits (last month about a million). We are not sure if the reason of this errors is on some configuration of IIS or the component server or in the code itself. The website is running on IIS 6 and Windows Server 2003 r2.
Excuse me this common error. I´ve found a lot of info in Google but I´ve not found my error. I´m trying to read some data from a custom section in web.config and I don´t know which is my error?
I have a web application written using VS201, ASP pages, .NET 4.0, C# and now that I am getting ready to publish to the clients server I have noticed the following error...
[Code]....
Line 26 is the error I do not understand what or why? At the top of several pages where I use the same code segment several times I declare a new instance of the errorlog class. Now all of a sudden it is reporting it as a Compiler Warning Message it as an error for every instance where I am declaring it.

When I get an Object Ref error, it can sometimes be a real pain to find out which variable is causing the error (when you can't debug). Is there a way for this error to throw the classname that isn't assigned?
We have created a new cname for our subdomain website. The new website is working properly with cname. We do have .net application inside the webiste which is not working with cname. For eg,1. http://servername/_folder1/app/mypage.aspx (Accessing .net application (App) website without cname)2. http://NewDomian.xxxx/app/mypage.aspx (Accessing .net application (App) website with cname)The first case is working perfectly, but when I access the second url, I got the following error.Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. Parser Error Message: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.Source Error:
I have upload my files in domain.after uploading,i run the site.i get the following error The EXECUTE permission was denied on the object 'xxxxxxx', database 'zzzzzzz', schema 'dbo'. what reason for this error raised and how to solve it?.
I've got a web application I've built that makes various database calls to render some charts and datagrids for MI reporting purposes. I've got my database calls initiating on Page_Load within the .vb for each page. The site impersonates identity for database access. Page_Load returns a datatable and populates an HTML table inside an ASP:Repeater. Still with me? Well, everything works fine here. My problem is within the Default.aspx.vb Page_Load sub.
The Page_Load sub (in Default.aspx.vb) returns a datatable the same way as the others but instead of rendering the results to a repeater, the datatable is saved as Session("dt"). The saved session "dt" is then used to populate a couple of charts I've got on the home page(default.aspx):
<script runat="server"> Public Function buildXML(ByVal Product As String, ByVal reportNameStr As String) As String Dim clDB As New clDB Dim clSB...........................
Form open in the iframe as well, but when I click submit button, I m creating a session variable and page redirect to form2.aspx. So when I get that session variable object, asp.net send me "Object reference not set to an instance of an object problem."
I totally do not understand of getting this message. When I run the application from vs2005 or from development machine everything works great, gets records, updates etc and database is on a different server. After deployment to webserver, application and database are on separate servers.

I have written an ASP.NET Web app using C#/ODP.NET, I have deployed my app on Win 2003 Server/IIS 6.0. After some time of operation the applicaion gives the error "Objet reference not set to an instance of the object" On fruther investigation I found that the connection is lost after some time and is restoted again when the cliend refrehes. Is this a but iin ODP.NET, Or something else? Is there any fix avaible to this problem? Is any one else faced this issue?
In the VS2005 environment, when I test my session to make sure the page redirects to the main page (itself) if the session is null, it works. There is no error.
The function I use for this is:

However, when it is in the production environment in IIS 6.0, when the session has timed out, and I then do a postback by doing some slider control, I see the page reload but immediately thereafter, it throws a Server Error exception of : Object reference not set to an instance of object.
however, why is it that the Slider1_TextChanged event fired even even after during page_load, the page was told to do a response.direct ?? shouldn't the entire page have gone through a full-page refresh life cycle ? why did it continue on to attempt to raise the Slider1_TextChanged event?
I'm new to programming in ASP.NET, but I'm making my way through Wrox's Beginning ASP.NET 3.5 in C# and VB.NET.
I'm at a section where I'm creating a BasePage. I successfully created a BasePage by creating a new class file in my App_Code folder called BasePage.cs with the following code:
[Code]....
If I run that code everything works out fine. The page loads and all is well. But, if I try to do the same thing to a page that uses my MasterPage.master file, I get the following error:
Object reference not set to an instance of an object.
Description:
An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Why is that? In the example code from the book (that also uses a MasterPage.master file), everything excutes and runs just fine. But in my test, I get the above error. I've tried comparing my pages to the books included source pages, but I can't find any differences.
We have an applicaiton that was converted to the new framework using the wizard in Visual Studio 2008. When we install the applicaiton in production and change the iis settings to use the 2.0 framework we start to see these errors in the event viewer on the web servers. We are using SQL Server Session State and have 3 web servers in a load balancer. Object reference not set to an instance of an object.</Message><StackTrace> at System.Web.SessionState.SessionStateModule.PollLockedSessionCallback...
I have just recently converted my VB code to C# and now having this error when I try to add an item to my listbox, and the value is coming from the item page. I get the error at this segement:
lstboxCart.Items.Add(cartItem.Display());
My listbox is supposed to add the product's name, quantity, and price onto one row.
Here's what I have so far:

My guess is that the source of the problem could be in the foreach loop from my cart class, shouldn't I be using that for arrays only? If I need to post any markup code or any other class, let me know.
I have the following code in my form load that loads the reports and assigns it to crystalreportviewer control. If Not IsPostBack Then
[Code]....
Following is the ApplyCRLogin Class
[Code]....
Now when I run the site it prompts me for the parameters and when I enter them and click on OK, I get the following error. "Object reference not set to an instance of an object." But the strange thing is if I comment the "If Not IsPostBack Then" condition, my report works fine. The problem is even when I want to go to the next page in report, the code get executed again and this takes time. Is there any other way to fix this?
I am trying to run the 15 minutes movies MVC application but I got the following error:
Object reference not set to an instance of an object.

I have 2 pages in my project (that are causing the problems). My default page has a FormView that for some reason will not let me access page events, such as buttons for instance, in code behind. They show up fine on page but are not visible in the page events drop down in code behind. We are using a work around for that.
The main issue now is that on my ViewTaxes.aspx page I need to get the values of some of the text boxes from the default page by Control Number, i.e. whatever record is being viewed on default page when you click the ViewTaxes link button, much more detailed information about that particular record is displayed on ViewTaxes. If on ViewTaxes I use a SELECT * statement I can access the ViewTaxes page when I click the button. We, of course, need to filter the data displayed by ControlNumber. When I add a WHERE clause to the DS on ViewTaxes page and click linkbutton on the default page I get an Object Reference error. This error seems to have something to do with a group of textboxes that are displayed via Session in codebehind. Values from default page being displayed in one section of ViewTaxes page. The error when thrown always points to Session("Owner1") = txtCust1.Text. If that code is removed then error will go to next Session variable, an so on.
I should also point out that both pages worked fine, no problems at all, using a test MySql table. We recently migrated the actual table that will be used from an Access database and replaced the test table. Can't find any spelling errors or anything of that nature. There are some Null fields in this database but it is set to allow Nulls.
Here I want when click on linkbutton it change text's color so I wrote below code:
protected void c(object sender, EventArgs e) { this.GetCustomersPageWiseMC(1, (sender as LinkButton).CommandArgument); BindDataListD(DLclassC, "classTI_documentry"); DataListItem item = (DataListItem)(sender as LinkButton).NamingContainer; foreach (DataListItem dlItems in DLclass.Items)
[Code] ....
For Linkbtnclass_Click it worked correctly and when I click on linkbutton it change color but for LinkbtnclassC_Click when I click on linkbutton it make this error:
Server Error in '/' Application.
Object reference not set to an instance of an object.
