Handling non-aspx pages 404 error

Posted By:      Posted Date: September 24, 2010    Points: 0   Category :ASP.Net


I have enabled customError in my web.config file and it handles 'Page not found' error for aspx pages or any other files types handled by ASP runtime. My problem is my application is on a remote host and when a user tries a url on my website that ends with something other than those files types handled by ASP run time, for example http://mywesites.com/sdkdhiufuhief.hei, it displays a detailed error page by the IIS which I really don't like the malicious users to see. It contains a lot of information like the physical path of the application.

How can I handle all 404 html error regardless of the file type and URL in my ASP.NET application?

Error: Access Denied on default.aspx and other pages of existing and new sites

Hi, since today we can't access the project portals of all our projects (Visual Studio TFS 2008/sharepoint admin 3.0 running on esx 4.0). I already checked every possible security settings, they're all OK. I also tried creating a new site but I can't access the site. I can however access all the settings. For example when I try to access: http://server/Sites/Profel I get the "Error: Access Denied" message and the browser is redirected to http://server/Sites/Profel/_layouts/AccessDenied.aspx?Source=http%3A%2F%2Fserver%2FSites%2FProfel%2Fdefault%2Easpx I have no problem navigating to: http://server/sites/Profel/_layouts/settings.aspx and I can go to al lot of pages, but when I want to create something like a calendar I can specify the parameters but when I click the create button I get the same error. http://server/Sites/Profel/_layouts/AccessDenied.aspx?Source=http%3A%2F%2Fserver%2FSites%2FProfel%2FLists%2Ftest%2Fcalendar%2Easpx&Type=list&name=%7B46CB3B46%2DD0F6%2D47F5%2DBA1A%2D3C9654A24A8E%7D I already tried this: http://support.microsoft.com/kb/926642  http://support.microsoft.com/kb/896861/en-us but no success Any help is welcome, Greetz, Peter

Error while using exception handling block el 4.1


Hi Folks,


i am trying to use tyhe exception handling block of Enterprise library 4.1.


I just createda polisy and used IndexOutOfRangeException and added a replace handler and a logging handler to it.

I am using the NotifyRethrow PostHandlingAction to the exception.


During runtime I am getting an exception on the HandleException event, The exception is added below:



Object reference not set to an instance of an object.

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.NullReferenceException: Object reference not set to an instance of an object.

Foundations: Error Handling In Workflows


Workflows often define long-running processes and an unhandled failure usually means termination. Avoid this scenario by handling exceptions properly.

Error Handling: Throwing Custom Exception Types from a Managed COM+ Server Application


Exception handling semantics in .NET are based on type, so you can create custom exceptions that have their own properties and methods. In .NET, exceptions are first-class citizens, and since they're the built-in error handling mechanism, all .NET-compliant languages must support exceptions. In addition, COM+ services are available to .NET code as Enterprise Services, so you can leverage exceptions in your Enterprise Services design.In this article the author describes custom exceptions, throwing exceptions across COM interop boundaries, and working with Enterprise Services.

.NET Exceptions: Make the Transition from Traditional Visual Basic Error Handling to the Object-Orie


If you're used to Visual Basic 6.0 and you're making the transition to Microsoft .NET, you will find that error handling is quite different from what you've used for years. Visual Basic .NET uses a more object-oriented solution to signaling and responding to unexpected problems while your program is running. This approach, called structured exception handling, has a number of advantages over the On Error statements provided in previous versions of Visual Basic. For instance, exceptions give you lots more information about exactly what went wrong in your app. To help you take advantage of this modern error handling paradigm, this article will show you how to raise and respond to exceptions, as well as how to create your own custom exception classes.

Propagate Error Info: Use ATL and C++ to Implement Error-Handling COM Objects


Predefined error codes returned from HRESULT aren't always much help for debugging COM C++ code. The C++ macros provided with this article produce an XML file listing the error and its context to make debugging easier. This article begins with an overview of error handling in COM, then discusses the COM interfaces used in the macros. It explains how C++ exceptions are caught and converted to COM-compatible error information, how events are logged with the event viewer, and how context is reported in the description string of IErrorInfo. The macros handle logic errors and errors returned by an object or API.

Web Part working fine on the top-level page but 'Not Safe' error on lower-level pages.


I have created a Web Part which reads and parses the SharePoint logs in order to display usage information of the page it resides on.  The Web Part works perfectly on the top page, reading and displaying the information desired.  However, once the Web Part is added to any page lower in the site heirarchy (sub-page) the same Web Part throws the following error:

Web Part Error: A Web Part or Web Form Control on this Page cannot be displayed or imported. The type could not be found or it is not registered as safe.

Of course the current version of the Web Part is in the SafeControls list on the web.config.

The Web Part was originally designed to return site activity only for the top default.aspx page and worked fine but started to fail in the manner described above once I added the following line of code to return a SPCo

Person.aspx 404 error

Hello all, New Sharepoint admin here, so please be gentle.  I'm trying to get the "My Profile" link to work in the upper-right drop down menu in our newly-installed Sharepoint 2010 site. I'm receiving a 404 error, likely due to the fact it's going to https://siteurl/Person.aspx?accountname whereas I'm trying to set it to go to https://siteurl/my/Person.aspx?accountname... I've followed a few guides on the internet regarding setting the MySite info in the "My Site Settings" of the User Profile Service Application. Currently I've got "my" in the Location field for "Personal Site Location," is this the proper place to change the url?  If I manually navigate to https://siteurl/my/Person.asx?accountname=domain\account the page loads without issue, the problem just seems to be getting sharepoint to go to that proper url. Any assistance would be much appreciated.  Pete

SharePoint ASPX Web Service Call Error

What is the correct error handling in custom model binding?

Hello,I am working on a Custom Model Binder where a certain error can occur.When this happens it returns null and a error is added to the ModelState.The problem is that in some projects I am using Fluent Validation and the errors messages I am adding through FV are not taking effect.The message added by the Model Binder always prevails.Should the Model Binder add error messages or just bind the field and return null if some problem happened?What would be the correct implementation for this?Thanks,Miguel

How to : Generic error handling function. Passing GridViewUpdatedEventArgs as EventArgs

Hi, I want to build a generic error handling function for handling inseted, updated, deleted events from formview, gridview and detail view. I am still a bit new to C# so I have encoutered a simple problem that I cannot resolve and cannot find an answer while searching google.Right now I handle error with validator for generic validation but I need to catch BLL error.I have different event handler for the different type of event : protected void FormView_AjoutCompte_ItemInserted(object sender, FormViewInsertedEventArgs e) { if (e.Exception != null) { Afficher_Erreur(e.Exception); e.ExceptionHandled = true; } } protected void GridView_ListeUtilisateurs_RowUpdated(object sender, GridViewUpdatedEventArgs e) { if (e.Exception != null) { Afficher_Erreur(e.Exception); e.ExceptionHandled = true; } } protected void GridView_ListeUtilisateurs_RowDeleted(object sender, GridViewDeletedEventArgs e) { if (e.Exception != null) { Afficher_Erreur(e.Exception); e.ExceptionHandled = true; } } I want to create a generic function that will handle them all, a function such as : private void GestionDerreur(EventArgs e) { if (e.Exception != null) { Afficher_Erreur(e.Exception); e.Exc

Modifying Customizing EditForm.aspx of Doc lib breaks Upload function - Unknown Error

Part of a bigger design issue really. But does anybody know why customizing EditForm.aspx of a Doc lib breaks the Upload function? and how to fix it so it does not. My version of the editform works great, but after an upload I get Unknown Error the resulting url looks like this: https://xxxxx.edu/sites/xxxx/_layouts/Upload.aspx?List=%7b0404432B-91A3-4E18-9202-5954E3A7E0D2%7d&RootFolder=%2fsites%2fmcpharm%2ftest3&Source=https%3a%2f%2fxxxxx.edu%2fsites%2fmcpharm%2ftest3%2fForms%2fAllItems.aspx --- The bigger design issue - disregard if you like: That said, the bigger design issue is we are trying to relate one list row to many documents, but don't want to seperate the docs into seperate folders and would like the solutoin to be seamless. We are going to add a look up from the doc lib to the list, but did not want to use anythng but the List's ID column. However, we do not want users to have to manually look up List row IDs in that form, and we did not want to use a list column that can be edited, even if we can add a unique column policy. My design and thinking is to build a few custom pages with dataviews to show row level details in both lists (1 to many) and a dataview to drive list level functions like edit, delete and upload docs. I think all the pieces are there except for the less than graceful upload function that fist uploads the file and then asks the

A customized EditForm.aspx page giving error because it has a "People and Group" field with a "Allow

My customized EditForm.aspx which has a "People and Group" column with the "Allow multiple selections" property as "Yes" was working fine until the Agusust cumulative update was applied into the MOSS server. Now it's giving me the error: "An unexpected error has occurred". Needless to say, when I change the "Allow multiple selections" property to "No", the customized EditForm.aspx page works fine.Forgetting whyMicrosoft introduced this error for now, is there a workaround that you are awre of?
