Hi Guys, I'm really stuck on this problem and I am hoping somone has a quick fix, only because I'll have to write my own hack if required. So, what I'm doing is simply calling the google web service. I've been stuck on this problem for a while. I receive a "Specified Cast Exception". When I investigate further, the type returned is an XmlTreeNode, where it should be a GoogleSearchResult. I programmed a seperate .NET application that calls the web service and it works no problem. My application dynamically loads an assembly which invokes the Google web service proxy. What I have done is captured the SOAP calls, the following is what happens when I call it from my test application:

Now, the first one worked and the second one didn't. Why, your guess is as good as mine. However, what I have noticed is that there is no content length attatched, which leaved the soap proxy guessing when the call is finished. However, it manages the first call ok but falls over on the second one. Is this possibly something to do with threading? Is there a thread waiting and it never fires back? I've notified Google, but I don't think they really care since everyone else is ok.
