This event is raised each time an asynchronous operation to open a stream that is used to send data to a resource completes. These operations are started by calling the OpenWriteAsync methods.
For more information about handling events, see Consuming Events.
The following code example demonstrates setting an event handler for this event.
Public Shared Sub OpenResourceForWriting2(ByVal address As String) Dim client As WebClient = New WebClient() ' Specify that the OpenWriteCallback method gets called ' when the writeable stream is available. AddHandler client.OpenWriteCompleted, AddressOf OpenWriteCallback2 Dim uri as Uri = New Uri(address) client.OpenWriteAsync(uri, "POST") ' Applications can perform other tasks ' while waiting for the upload to complete. End Sub
