How to Know what Caused an Error

Jonathan Wood

Greetings,

I have a Website that emails me any time an error occurs. I have debugging
on so that it can include page and line number information.

So I got a ton of the email below. Unfortunately, while I see it has
something to do with having "unsafe" characters in the query string, it
doesn't tell me on which page. Line 0 of App_Web_3uw3mai 2.5.cs means
absolutely nothing to me. And it's too big a site to try and guess.

Is there no way to figure out what caused this error?

Thanks.

Jonathan

You obviously should include all related information like

Request.RawUrl, Request.Post.To String()...
into you report logging...

PS: That error happens usually when HTML tags are tried to be submitted
through the input box. By default ASP.NET prevents that.

You can set validateRequest ="false" in web.config to disable validation.
<pages validateRequest ="false">

I didn't see a Request.Post property. Did you mean something else?

Thanks.

Yea, but usually you have tested the code. So it's not easy to guess were
problem is unless you can replicate the problem or simply ignore the error
message.
There are a lot of (spamming) robots that trying to submit the form with bad
information.
Or hacking attempts looking like this (taken from real site)

Yeah, most of the users I'm dealing with are not technical, and my site's
available only to paying customers. So, as far as I know, I'm just dealing
with things like the user hitting the back button and so a page is loaded in
the incorrect context, or in this case putting invalid characters in an
input string.

But I'm updating my reporting routines as suggested.

Thanks.

BTW, the hacking attempt you posted shouldn't cause any problems as long as
the page uses parameterized arguments, right.

>>You obviously should include all related information like

Request.RawUr l, Request.Post.To String()...
into you report logging...

I guess. Virtually all errors occur in my code so I can look at it. I
guess this is a rare exception.

>>PS: That error happens usually when HTML tags are tried to be submitted
through the input box. By default ASP.NET prevents that.

You can set validateRequest ="false" in web.config to disable
validation.
<pages validateRequest ="false">

I'm not certain how comfortable I am with that, but that's good
information to know.

Thanks.

Greetings,

I have a Website that emails me any time an error occurs. I have
debugging on so that it can include page and line number information.

So I got a ton of the email below. Unfortunately, while I see it has
something to do with having "unsafe" characters in the query string, it
doesn't tell me on which page. Line 0 of App_Web_3uw3mai 2.5.cs means
absolutely nothing to me. And it's too big a site to try and guess.

Is there no way to figure out what caused this error?

Thanks.

Jonathan

strange runtime error caused by enum

Hi, I've been trying to debug a strange runtime error for the last 5 hours... I'm hoping someone might have an insight about it. I have an application that creates a vector of MyDisplay objects (MyDisplay is a custom class) and then uses them in various ways. The application has been compiling and running fine. Then I added a member variable of type enum to MyDisplay. So my class def now looks like this:

The easy way to turn off automatic updates for Windows 10/11

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
