View 1 RepliesVS 2008 : Add A "resume Download" Feature To A Program?
Apr 21, 2011its possible to add a "resume download" feature to my program as something doesn't seem to be right when I want to download the latest videos from my server.The application will download most of the video, but will then stop at random times. After the download has stopped, no more data will be received. Thats why I need a "download resume" feature in my application, so the whole file will be downloaded and corrupt files aren't being saved.
Here's my so far
Private WithEvents wClient As New WebClient
Private Sub wClient_DownloadProgressChanged(ByVal sender As Object, ByVal e As System.Net.DownloadProgressChangedEventArgs) Handles wClient.DownloadProgressChanged
[code].....
I was thinking of adding a timer to my project, and if data has not been received for more than "x" seconds, the file will in a "paused" state.The next step would be "resuming" the download so the file is downloading again.
Other Notes:The files download fine in IE and chrome.The files are around 5MB to 30MB in size and upto 10 minutes in length.

Detecting Resume From Standby And Reboots?
Aug 13, 2009I need something that will log the time the computer came out of standby, or the user logs in the first time from a reboot.
Basically, I want to time computer usage but in simple terms where computer is being used after waking or after rebooting.
So, All I need is a detection scheme. Does windows provide that? I am probably targeting .NET but can do Win32 API. Or do I have to do anything like that all?
I am thinking if I make a service, windows will handle the launching of the service and that way I can detect usage. But is that the most efficient way?
I am using XP Pro and Visual Studio 2005

Thread Do Not Resume When The Delegate Returns?
Jun 2, 2010It seems that there is a glitch in Vb, While having some tasks ( Thread ) queued using Tasks if you try to use Invoke, the thread do not resume when the delegate returns.If BeginInvoke is used, it works but the problem is that it become impossible to execute a delegate synchronously.This does force the use of the AutoResetEvent to control the thread.The problem comes when the thread execute some code in a other classes, using a single AutoResetEvent within many classes just give a very dirty code.
