Create a callback method that will be used to retrieve the results of the asynchronous message call. This method needs to accept a parameter of type IAsyncResult: Public Sub LogReadCallBack(ByVal ar As IAsyncResult) . . . End Sub 5. At the top of the code editor, in the right object drop-down list, choose btnAsyncRead. In the left drop-down list, choose the click event. Add code that declares a variable of type AsyncCallback and instantiate it, passing in the address of the LogReadCallBack method you created. On the next line of code, call the BeginInvoke method of the LogReader delegate, passing in the file path and the AsyncCallback variable. Capture the return value in a variable of type IAsyncResult. Private Sub btnAsyncRead_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles btnAsyncRead.Click Dim aCallBack As AsyncCallback = New AsyncCallback _ (AddressOf Me.LogReadCallBack) Dim ar As IAsyncResult = LogReader.BeginInvoke _ (txtLogPath.Text, aCallBack, Nothing) End Sub 6. Add code to the LogReadCallBack method that calls the EndInvoke method of the LogReader delegate, passing in the file path and the IAsyncResult parameter. Display the results in a message box. Public Sub LogReadCallBack(ByVal ar As IAsyncResult) MessageBox.Show(LogReader.EndInvoke(ar)) End Sub 7. Select Build Build Solution. Make sure there are no build errors in the Error List window. If there are, fix them, and then rebuild. 8. Select Debug Run. When the form launches, click the Async Read button. After clicking the Async Read button, click the Message button. This time, you should get a response, because you called the ReadLog method asynchronously. 9. When you have finished testing, close the form. 10.
