HI there!
I am trying to consume a web service implemented in Perl (SOAP::Lite)
using VS Express 2008. I already implemented a client in java without
problems.
I succeeded in calling the web service, but the SOAP-Call returns a
complex type which is not handled correctly.
Invoke() throws an exception stating that an object of type
system.String can not be assigned to type RetDataType. Debugging shows
that the deserializer seems to handle the first return variable only
(string), ignoring the second (int), completely unaware of the complex
return type.
I would be glad if anybody could give me a hint.
Excerpt from WSDL-proxy:

I have 2 web services. Web service "Main" and a Web Service "Proxy". I also
have a shared libary of complex types.
The "Proxy" web service simply calles methods of the "Main" web service.
When I invoke a method in the "Main" web service directly it returns an xml
document that lists all the "type" information of each element and they
appear to be correctly reflecting my complex type.
However, when I invoke the "Main" web service...

I want to be able to reset a complex property in a PropertyGrid. I know that for properties that are ValueTypes you can include System.ComponentModel.DefaultValue in the declaration of the property. But, for complex property types (e.g., instance types) this does not work because System.ComponentModel.DefaultValue requires a constant value
In order to indicate if a property should be serialized you can include a boolean function named...

Hello,
I'd like to understand why the following code does not compile. It
looks like a strangeness in connection with overload resolution for the

The conversion operator double() of class B is called for the member
complex::operator*=(double) as expected, but not for operator*(complex,
double).
The effect is, that the template matching (or overload resolution)

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.

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.
