Here's the code ;
CODE:
I have converted this parallel extension c# code sample to VB.NET

using the Developerfusion tool here but I am getting multiple errors that I cannot resolve with my limited C# experience.
1) After getting errors I converted System.Runtime.CompilerServices.Extension to Global.System.Runtime.CompilerServices.ExtensionAttribute which is the closest I could come up with, and I get errors on the line (26)
Return SendTaskCore(ping, userToken, Function(tcs) ping.SendAsync(address, tcs))saying that ping.SendAsync(address, timeout, tcs) does not produce a value
2) Around line 196 handler = Function(sender, e) EAPCommon.HandleCompletion(tcs, e, Function() e.Reply, Function() ping.PingCompleted -= handler)
I get an error on 'ping.PingCompleted' saying'Public Event PingCompleted(sender As Object, e As System.Net.NetworkInformation.PingCompletedEventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.

View 1 RepliesI'm using the book titled "Database Programming with Visual Basic .NET and ADO.NET: Tips, Tutorials, and Code".
I'm going through the chapter that has me do data binding by setting the properties of a DataGrid and TextBoxes.
It had me drag a DataAdapter onto the form and had me generate a DataSet. This part works fine. It also had me set the binding through the Text propert of each TextBox. This also works fine as it displays the correct data as the user navigates through the DataGrid.
I think there may be something missing from the code samples in the book because saving the data back to the database is not working and even no errors are reported.[code]...
