I performed wsdl on SQL2000 reporting service and have a question regarding
the following proxy class. Right before render procedure declaration you
have code that looks like html or xml. What is this, how does compiler and
application interpret at run time, and how do I read it and understand what
I should specify if I were to write something similar.
Also, the public function declaration has a return value of
As <System.Xml.Serialization.XmlElementAttribute("Res ult",
DataType:="base64Binary")> Byte().
What does this mean? Thank you.
