• .NET Development web service locks up when using an inherited class

  Hi, has anyone seen this I'm using a basic class such as. public class a <XMLElement(type:=gettype(clsTestClass)), _ XMLElement(type:=getType(clsDerivedClass))>_ public a1 as clsTestClass end class DerivedClass inherits TestClass Everything compiles correctly, but when I try to put a clsTestClass object in a1 and then use it to pass to a web service, the soap call freezes up apparently at the  accessorcollection.findaccessor call.  Putting a clsDerivedClass object in works fine.  I'm working around it by getting rid of the derived class and just adding it all to the base class, but it's bad form and a lot ...Show All

• Visual C++ timeval struct incorrect

• Visual Studio 2008 (Pre-release) How do you read a lambda expression?

  Hi All, I am trying to figure out how to read out loud a lambda expression.  For example if I have the following i => (i %2) == 0 or c => c.Age < 50 etc. How would I read them to my children Cheers, Clint personally, i love the lambda expression additions. in school, i used SML most of the time, and it was an amazing language. i know lamba expressions are probably a little foreign for a lot of programmers, but the power of being able to inline functions creates many possibilities for streamlined implementations. give it a chance, and then you probably will wonder where they have been your w ...Show All
