Console::WriteLine( "There are {0} subkeys under Test9999.", test9999->SubKeyCount.ToString() );
array<String^>^subKeyNames = test9999->GetSubKeyNames();
for ( int i = 0; i < subKeyNames->Length; i++ )
{
   RegistryKey ^ tempKey = test9999->OpenSubKey( subKeyNames[ i ] );
   Console::WriteLine( "\nThere are {0} values for {1}.", tempKey->ValueCount.ToString(), tempKey->Name );
   array<String^>^valueNames = tempKey->GetValueNames();
   for ( int j = 0; j < valueNames->Length; j++ )
   {
      Console::WriteLine( "{0,-8}: {1}", valueNames[ j ], tempKey->GetValue( valueNames[ j ] )->ToString() );
