The following code example downloads a file group named HelpFiles, and displays download progress in a status bar. This example requires that you deploy a Windows Forms application, and that your main form has a StatusStrip control, and a ToolStripStatusLabel control named downloadStatus.
void LaunchAppUpdate() { if (ApplicationDeployment::IsNetworkDeployed) { ApplicationDeployment^ ad = ApplicationDeployment::CurrentDeployment; ad->UpdateCompleted += gcnew AsyncCompletedEventHandler(this, &Form1::LaunchAppUpdate_UpdateCompleted); ad->UpdateAsync(); } } void LaunchAppUpdate_UpdateCompleted(Object^ sender, AsyncCompletedEventArgs^ e) { if (!e->Cancelled) { if (nullptr != e->Error) { System::Windows::Forms::DialogResult dr = MessageBox::Show( "The application has been updated. Restart?", "Restart Application", MessageBoxButtons::OKCancel); if (System::Windows::Forms::DialogResult::OK == dr) { Application::Restart(); } } else { // Replace with your own error reporting or logging. MessageBox::Show( "The application encountered an error in " + "downloading the latest update. Error: {0}", e->Error->Message); } } else { // Replace with your own error reporting or logging. MessageBox::Show( "The update of the application's latest version was " + "cancelled."); } }
