>Less code justify My.App use. :)
>But something that I still not understand is why doesn't provide a way to show operation progress status (for example in My.Computer.FileSystem.CopyFolder) even using other approachs to accomplish this feature (an event where you put some code to show the progress, for example).
>This feature is very usefull!
