// Function: PromptUserForPassword
//
// Purpose:
//   This function prompts the user with a password dialog and returns the
// results to the caller.
//
// Arguments:
//   LPINETSERVER pInetServer [in/out] - provides default values for username
//     and password, and allows us to save password to account if user asks us
//     to. User-supplied username and password are saved to this structure
//     for return to the caller.
//   HWND hwnd [in] - parent hwnd to be used for password dialog.
//
// Returns:
//   TRUE if user pressed  TEXT("OK") on dialog, FALSE if user pressed  TEXT("CANCEL").
