如何用VC读取注册表二进制值，比如ShutdownTime？求助~

Question

用RegQueryValueEx读取数据，应该放在哪种数据类型中呢，求有效代码~
下面这段是自己的提取TypedURLsTime的代码。不知问题在哪。。
int main()
{
HKEY hKey;
DWORD lpType = REG_BINARY;
BYTE time[64];
DWORD timeSize = sizeof(time);
RegOpenKeyEx(HKEY_CURRENT_USER, "Software\Microsoft\Internet Explorer\TypedURLsTime", 0, KEY_ALL_ACCESS, &hKey);//打开键。
RegQueryValueEx(hKey, "url1", NULL, &lpType, (LPBYTE)time, &timeSize);//提取内容。
printf("%s", time);
system("pause");
}

Answer 1

#include
#include
#include //调用FILIETIME等函数。
int main()
{
HKEY hKey;
DWORD lpType = REG_BINARY;
DWORD timeSize;
if (RegOpenKeyEx(HKEY_CURRENT_USER, "Software\Microsoft\Internet Explorer\TypedURLsTime", 0, KEY_ALL_ACCESS, &hKey) == 0)//打开键。
{
RegQueryValueEx(hKey, "url1", NULL, &lpType, NULL, &timeSize);
DWORD time = new DWORD[timeSize];
if (RegQueryValueEx(hKey, "url1", NULL, &lpType, (LPBYTE)time, &timeSize) == 0)
{
LONGLONG *t = (LONGLONG)time;//强制类型转换将地址赋给LONGLONG型。
LONGLONG time1 = *t;//time1为注册表中存储的二进制时间。
FILETIME filetime;//filetime为UTC。
filetime.dwHighDateTime = time1 >> 32;//filetime的前半段。
filetime.dwLowDateTime = time1 & 0xffff;//filetime的后半段。
FILETIME localfiletime;//localfiletime为UTC+8。

FileTimeToLocalFileTime(&filetime, &localfiletime);
SYSTEMTIME systemtime;
FileTimeToSystemTime(&localfiletime, &systemtime);
printf("时间为：\n%d年%d月%d日%d时%d分%d秒\n", systemtime.wYear, systemtime.wMonth, systemtime.wDay, systemtime.wHour, systemtime.wMinute, systemtime.wSecond);
}
}
system("pause");
}
