Hi all,
Like the subject says. I want to allow a user to clear out a config
setting. The problem is when my app hits the code:
ConfigurationManager.Write(configData);
I get:
System.InvalidOperationException: There was an error generating the XML
document. ---> System.InvalidOperationException: System.DBNull cannot be
serialized because it does not have a default public constructor.

I was just looking at an article about using nullable value types. (value
types that can effectively have no value and not be set).
The syntax is to append a question-mark to the value type in the
declaration, eg:
int? age;
I don't like that much, I think it would be much more consistent to use a
new keyword, such as "nullable". But anyways...

I have been getting this message and can't resolve the problem. I have
checked the AntiVirus software and added the application directory to
the exculsion list. The application is on a web farm, using SANS for
file storage. It seemed to start once we installed the SSL cert. But,
that could be just when we noticed the problem. Any ideas would be
greatly appreciated.
Thanks

message. When I try to run any webmethod from the webservice locally in the
browser I first get a "This page cannot be display IE error...

System.InvalidOperationException: WebServiceBindingAttribute is required on

My environment: Visual Studio 2005, targeting FX 2.0; I've developed a Web
Service which uses DIME to transfer file attachments to and from the server.
I'm using WSE 2.0 SP3 which is supposed to support FX 2.0, as far as I know.
(We will soon move on to MTOM, however I'm stuck with DIME for now; the
solution was originally written for FX 1.1, and I...

I have a web service application which uses 3rd party assemblies. I recently
upgraded my solution to use .NET Framework 2.0 instead of .NET Framework

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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
