C/C++注册表【5】其他类型的键值设置

1、DWORD 类型键值的设置

void CTestDlg::OnBnClickedButton1()
{
  // TODO: 在此添加控件通知处理程序代码
  HKEY hKey = NULL;
  TCHAR *lpszSubKey = _T("Console");
  LONG lRet = RegOpenKeyEx(HKEY_CURRENT_USER, lpszSubKey, 0, KEY_ALL_ACCESS, &hKey);
  if (lRet == ERROR_SUCCESS) {
    DWORD dwValue = 10;
    RegSetValueEx(hKey, _T("TestDWORD"), 0, REG_DWORD, (LPBYTE)&dwValue, sizeof(DWORD));

    DWORD dwBuffLen = sizeof(DWORD);
    BYTE *lpByte = new BYTE[dwBuffLen];
    ZeroMemory(lpByte, dwBuffLen);
    memcpy(lpByte, &dwValue, dwBuffLen);
    RegSetValueEx(hKey, _T("BYTEDWORD"), 0, REG_DWORD, lpByte, dwBuffLen);
    delete[] lpByte;

    DWORD dwRealValue = 0;
    dwBuffLen = sizeof(DWORD);
    RegQueryValueEx(hKey, _T("TestDWORD"), NULL, NULL, (LPBYTE)&dwRealValue, &dwBuffLen);

    RegCloseKey(hKey);
  }
}

2、子键下默认键值的设置

void CTestDlg::OnBnClickedButton1()
{
  // TODO: 在此添加控件通知处理程序代码
  HKEY hKey = NULL;
  TCHAR *lpszSubKey = _T("Console");
  LONG lRet = RegOpenKeyEx(HKEY_CURRENT_USER, lpszSubKey, 0, KEY_ALL_ACCESS, &hKey);
  if (lRet == ERROR_SUCCESS) {
    CString strValue = _T("cctry.com");
    RegSetValueEx(hKey, NULL, 0, REG_SZ, (LPBYTE)strValue.GetBuffer(), strValue.GetLength() * sizeof(TCHAR));
    strValue.ReleaseBuffer();

    BYTE szBuf[20] = { 0 };
    DWORD dwBuffLen = 20;
    RegQueryValueEx(hKey, NULL, NULL, NULL, szBuf, &dwBuffLen);

    CString strByte;
    strByte.Format(_T("%s"), szBuf);
    MessageBox(strByte);
    RegCloseKey(hKey);
  }
}
