>         {
>             public Form1()
>             {
>                 InitializeComponent();
>             }

>             private void button1_Click(System.Object sender, System.EventArgs e)
>             {
>                 try
>                 {

>                     //Create a file vault interface and log into a vault
>                     IEdmVault5 vault = new EdmVault5();
>                     vault.LoginAuto("MyVaultName", this.Handle.ToInt32());

>                     //Get the vault's root folder interface
>                     string message = "";
>                     IEdmFile5 file = null;
>                     IEdmFolder5 folder = null;
>                     folder = vault.RootFolder;

>                     //Get position of first file in the root folder
>                     IEdmPos5 pos = null;
>                     pos = folder.GetFirstFilePosition();
>                     if (pos.IsNull)
>                     {
>                         message = ("The root folder of your vault does not contain any files.");
>                         MessageBox.Show(message);
>                         return;
>                     }
>                     message = ("The root folder of your vault contains these files: " + "\n");
>                     while (!pos.IsNull)
>                     {
>                         file = folder.GetNextFile(pos);
>                         message = message + file.Name + "\n";
>                     }

>                     //Show the names of all files in the root folder
>                     MessageBox.Show(message);

>                 }

>                 catch (System.Runtime.InteropServices.COMException ex)
>                 {
>                     MessageBox.Show("HRESULT = 0x" + ex.ErrorCode.ToString("X") + "\n" + ex.Message);
>                 }
>                 catch (Exception ex)
>                 {
