I use this function like this:

  LPCSTR lpszKey = "SOFTWARE\\MyProgram";
  HKEY hKey = NULL;
  LONG lResult = RegOpenKeyEx(HKEY_LOCAL_MACHINE, lpszKey, 0, KEY_READ,
                              &hKey);
  if (lResult != ERROR_SUCCESS)
  {
    AfxMessageBox("Failed to access registry!");
    AfxAbort();
  }

  DWORD nEntryType = 0;
  DWORD nDataSize = 255;
  BYTE szPath [255];
  lResult = RegQueryValueEx(hKey, "Path", NULL,
                            &nEntryType, szPath, &nDataSize);
  if (lResult != ERROR_SUCCESS)
  {
    AfxMessageBox("Failed to access registry!");
    AfxAbort();
  }
  else
  {
    strcpy(Path, (const char*) szPath);
  }
