Property Value

Type: System::String^

A String representing the name of the file group.

You can initiate multiple calls to DownloadFileGroupAsync and download multiple file groups simultaneously. Use Group to determine which event callbacks correspond to which group.

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.");
    }
