Clickonce install from CDI generated the deployment files into a local directory with specified installation URL. My prolbems: - If there is an internet connection on the client machine, it skips the files on the local hard drive, immediately start downloading from the web. - if there is no internet connection, the setup.exe fails (which is the startup program from a CD), but the application icon installs the software well. I implemented a custom async update. When I call the CheckUpdateAsync method I have got an exception in the Application.ThreadException event, not in the AsyncCompleted event as the MSDN says (in the e.Error)... Why? Thanks. lelez ------------ Here it is the code: try { ApplicationDeployment dep = ApplicationDeployment.CurrentDeployment; dep.CheckForUpdateCompleted += checkHandler; dep.CheckForUpdateAsync(); } catch (System.Net.WebException) { // never runs! System.Windows.Forms.MessageBox.Show("There is no internet connection."); } catch (Exception ex) { xxxx.Common.Util.Logger.LogException(ex); } Here it is the handler: private static void dep_CheckCompleted(object sender, CheckForUpdateCompletedEventArgs e) { if (e.Error is System.Net.WebException) { System.Windows.Forms.MessageBox.Show("There is no internet connection."); return; } ApplicationDeployment dep = ApplicationDeployment.CurrentDeployment; dep.CheckForUpdateCompleted -= checkHandler; try { if (e.UpdateAvailable) { ContinueQuestionEventArgs ce = new ContinueQuestionEventArgs(e.AvailableVersion.ToString()); // Ask the user about continue... if (updateIsAvailable != null) updateIsAvailable(null, ce); if (ce.Continue) { dep.UpdateCompleted += updateHandler; dep.UpdateAsync(); } } } catch(InvalidOperationException ex) { xxxxx.Common.Util.Logger.LogException(ex); } } // dep_CheckCompleted... ClickOnce is designed as an Internet technology. If you want to play outside
of that box, you have to be a bit creative. One option is to setup the Cassini web server to load on the CD and then have it open a browser window to the drive in question.You can then "click once" install. If you are putting the software on a CD, however, it seems wiser to just have an install. If you need to update, bootstrap the startup to check for newer files and allow it to die gracefully if there is no Internet connection. -- Show quoteGregory A.

So I think It is not a question of creativity... Anyway thanks your answer. My bigger problem is the second one, that I have got an exception in the main thread when I try to get update information with no internet connection. MSDN promises that I will get exceptions in the Completed event handler in the params (e.Error). Instead this behaviour I have got the exception in the main thread and I could catch only here... lelez ----------------------------------- http://www.lelez.hu ICQ: 177465172 I will have to look at the final bits because it appears things have changed
a bit since I have last played with this. :-) After a quick search, I fond something that might help: http://winfx.msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_fxdeploy/html/ccee6551-a1b9-4ca2-8845-9c1cf4ac2560.asp -- Show quoteGregory A.
