AsyncCallback

Question

I can't get this to work

voidcrawlForInformation() {

String^ fileName =

"http://en.wikipedia.org/wiki/Law_of_cosines";

String^ url =

"http://en.wikipedia.org/wiki/Law_of_cosines";

String^ query =

"http://en.wikipedia.org/wiki/Law_of_cosines";

System::Web::

HttpRequest^ httpStream =

gcnewSystem::Web::HttpRequest(fileName, url, query);

System::IO::

Stream^ stream =

httpStream->GetBufferlessInputStream();

// array<unsigned char^> buffer

// int System32

// int count

// System::AsyncCallback callback

// Type System::Object

array<unsignedchar^, 1> *arrayList = newarray<unsignedchar^, 1>();

// IntelliSense: a delegate type is not allowed here      on AsyncCallback

// IntelliSense: identifier "MyTaskIsCallback" is undefined    

AsyncCallbackwebSearch = gcnewAsyncCallback(MyTaskIsCallback);

stream->BeginRead(arrayList, 0, 4294967296.0f, webSearch, stream);

// IntelliSense: function "System::IO::Stream::BeginRead" cannot be called with the given argument list
//            argument types are: (std::array<System::Byte ^, 1U> *, int, float, <error-type>, // System::IO::Stream ^)
//            object type is: System::IO::Stream ^

}

// The delegate must have the same signature as the method

// it will call asynchronously.

publicvoidMyTaskIsCaller(IAsyncResultresult) {

// IAsynResult - IntelliSense: a parameter cannot have a C++/CLI interface class type

}

};

with errors :

 6 IntelliSense: identifier "MyTaskIsCallback" is undefined                                                                    IntelliSense: a delegate type is not allowed here                                                               9 IntelliSense: a parameter cannot have a C++/CLI interface class type
