On OnInitDialog() of the parent dialog I used the Create() to create the child dialog and i am hiding it initially and calling this child dialog at a later use

if (my_variable & 1)
{
   // Drive A: available
}
if (my_variable & 2)
{
   // Drive B: available
}
if (my_variable & 4)
{
   // Drive C: available
}

cout << "Available drives -\n";
for (DWORD i = 0; i < 26; ++i)
{
   if (my_variable & (1 << i))
   {
      cout << char(65 + i) << ":\n";
   }
