HRESULT ImportConfigFromRegistry(IltmsServer* server, HKEY hkeyParent, LPCTSTR pszKeyName, LPCTSTR pszValueName) 
{ 
   HRESULT hr; 
   CRegKey key; 
   LONG result; 
   DWORD dw = 0; 
   CString v; 
   // get the configuration from the registry 
   result = key.Open(hkeyParent, pszKeyName); 
   if(result != ERROR_SUCCESS) 
   { 
      hr = HRESULT_FROM_WIN32(result); 
      goto error; 
   } 
   result = key.QueryStringValue(pszValueName, NULL, &dw); 
   if(result != ERROR_SUCCESS)
