I have a vendor web service that I have created a web application to
interact with. The service works fine in VS 2003 but fails in VS 2005. I
have implemented a proxy between the web client and web service to capture
the soap calls and both the request and response are identical. The problem
occurs in VS 2005 when the .net runtime attempts to de-serialize the soap
response into the custom type defined in the wsdl. The exact error message
is
Unable to cast object of type 'System.Xml.Xml Text' to type
'System.Xml.Xml Element'.
Stack Trace:
[InvalidCastExce ption: Unable to cast object of type 'System.Xml.Xml Text' to

My first thought was to look at the type definitions generated when I set
the web reference in VS 2005, but it appears from the stack trace that this
is not available in the IDE at design time as it is dynamically compiled.
How can I see the Xml serialization attributes that were applied when the
web reference was set?
Any help is most appreciated.

Hi all and thanks in advance for your help,
I am having problems deserializing an object which seems to be serializing just fine. I save the byte array of the serialized object in the database (when I check the database the field that holds the binary data seems populated), but when I want to deserialize this same byte array the application fails and gives me the following error:

Summary:
I have been trying to make requests of a web service provided by Axis using
a dotnet client with code generated by wsdl.exe and have
been getting exceptions when trying to process the response.
As a result of seraching news groups I guessed that the SOAP response
defines an array element in a way that causes the dotnet deserialization
routines to put the content in a generic object array (object) BUT the
content is supposed to...

I tried to post this question before, but there was an error when posting.
I case it did get posted and in order to avoid duplication, I'll just repost
a summary.
I have written a dotnet client that accesses a Axis provided web service.
The client uses the code generated, using wsdl.exe, from the wsdl file
provided by the web service provider.
The web response has the following schema (roughly):

Hi,
I was wondering how I would go about deserializing a file that was serialized from a different project. I've tried a couple things, but I can't really seem to figure it out. When looking it up, it seemed like it would be solved by just including a class project that did the actual serializing and deserializing, but when I tried this, I still couldn't get it to work. I created a DLL that was referenced by both of my projects, the server...

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.
