Hi,
I am experiencing a strange problem. I am reading and writing xml files via
XmlDocument and XmlTextWriter. In the debugger everything works fine but
outside the debugger I receive the following error: "The
type initializer for "System.Xml.Sch ema.Validator" threw an exception.".
When running from the debugger (debug or release) no exception is thrown.
I wrote a small console app that replicates the problem -- I've just attached
the default class which gets run. Output outside the debugger is as follows
------------------
Creating xml file
Reading xml file
Error reading xml file
The type initializer for "System.Xml.Sch ema.Validator" threw an exception.
Press a key to exit
------------------
I know that this code worked at some point in time and I do not get the
error message when running debug or release from the debugger. Runnning
WinXP SP2 and Visual Studio .Net 2003 (C#). Please feel free to correct me
if I am doing something incorrectly or let me know if it runs error free for
you.
Thanks in advance,
Chris

I ran your code under the debugger, then in release mode. No errors. Set the
debugger to break on all exceptions, No errors.

Hi,
While debugging my application when an explicit exception is thrown by me
(or an implicit exception is thrown internally) which is not handled
anywhere in the stack,
the execution breaks as expected but I can not continue.
I try start the execution and go back to running mode, but it always comes
to the same line
where the exception is first thrown.

Hi there,
I'm just curious as to something. I have just added an exception
handler at the entry point to my application, within the IDE any unhandled
exceptions fallback to this and enable me to disable a dialog of my liking.
Now if I run the application outside of the IDE I recieve the standard
"Unhandled exception" dialog provided by .NET giving me the ability to
continue or quit.
I wasn't actually aware that exception handling...

I have a Windows Forms application (VB.NET 2.0) which uses a Class Library

The application runs fine, but when I run it in debug mode, I get several "A

I want to get rid of these exceptions, but I can(t find where they occur.

Hi,
I have a .NET solution that contains a dll project and a tester application
project which, of course, invokes the dll. The dll project has exception
handling in it. What's happening is that when I run the executable from
within the .NET studio environment, thrown exceptions are caught and handled
correctly (both debug and release mode). However, if I run the executable
from outside the .NET studio, none of the exceptions get caught....

I have a class where I throw a new exception from a method
My calling code (in a different class) is wrapped in a Try/Catch block, but
it's not catching. Instead the IDE is highlighting the ThrowNew Exception
line in the class and saying it was unhandled.
Looking for some help.
Thanks!

I don't like the way every time I write a bad sql query the debugger
takes me to the database access code. It's extremely stable and
reliable and the exceptions being thrown are because of SQL queries
data passed to it. I don't want to handle or supress exceptions at
that point in the application, but rather ignore them so the debugger
handles them in the correct place, further up the call stack.
In java I could normally add a "throws...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
