重新启动后删除注册表项

Question

I save directory path to registry with this code:

HKEY hKey;
RegCreateKeyEx(HKEY_CURRENT_USER, L"Software\\BArtWell\\MyApp", 0, NULL, REG_OPTION_VOLATILE, KEY_WRITE, NULL, &hKey, NULL);
RegSetValueEx(hKey,L"Directory",0,REG_SZ,(LPBYTE)sz,(DWORD)wcslen(sz)*sizeof(wchar_t));
RegCloseKey(hKey);

And it is working fine before reboot. But after reboot path HKCU\\Software\\BArtWell\\MyApp doesn't exists. Tested on XP and Windows7 with same result. What I do wrong?

Answer 1

Read the documentation for REG_OPTION_VOLATILE . Then replace it with 0.
