1.如何向注册表中写值

//写入注册表为DWORD类型
bool SetRegValue(LPCTSTR lpSubKey, LPCTSTR lpValueName, DWORD dwValueKey)
{
	bool bRet = false;
	HKEY hKey;
	DWORD dwDispoistion = REG_OPENED_EXISTING_KEY;

	if (ERROR_SUCCESS == ::RegCreateKeyEx(HKEY_LOCAL_MACHINE, lpSubKey, 0, NULL, REG_OPTION_NON_VOLATILE,
		KEY_WRITE, NULL, &hKey, &dwDispoistion))
	{
		if (ERROR_SUCCESS == ::RegSetValueEx(hKey, lpValueName, 0, REG_DWORD, (BYTE*)&dwValueKey, sizeof(DWORD)))
		{
			bRet = true;
		}
	}
	::RegCloseKey(hKey);
	return bRet;
}

// 写入注册表为LPCTSTR 类型
bool SetRegValue(LPCTSTR lpSubKey, LPCTSTR lpValueName, LPCTSTR lpValueKey)
{
	bool bRet = false;
	HKEY hKey;
	DWORD dwDisposition = REG_OPENED_EXISTING_KEY;

	if (ERROR_SUCCESS == ::RegCreateKeyEx(HKEY_LOCAL_MACHINE, lpSubKey, 0, NULL, REG_OPTION_NON_VOLATILE,
		KEY_WRITE, NULL, &hKey, &dwDisposition))
	{
