What do you call asynchronous web request in VB.NET?

Question

I am currently using the following code to create a web request:

Dim myRequest As WebRequest = WebRequest.Create("http://foo.com/bar")
Dim myResponse As WebResponse = myRequest.GetResponse()

The problem is that it “blocks” the program until the request completes (and the program freezes if the request never completes). How do I change something like this to execute asynchronously so that other tasks can be completed during the completion of the web request?

Answer 1

You will use BeginGetResponse to add AsyncCallback, which basically points to some other method in your code that will be called when WebRequest returns. There is a good example here .

Answer 2

myRequest.BeginGetResponse()

EndGetReponse(), ( WaitHandle, callback ).
