DWORD和unsigned int

Question

我收到此錯誤，無法更正它。任何幫助表示讚賞。謝謝。 錯誤C2440：「=」：不能從「DWORD *」轉換爲「無符號整型」 智能感知：類型「DWORD *」不能被分配給類型「無符號整型」的實體

using namespace std; 
typedef vector<WIN32_FIND_DATA> tFoundFilesVector; 
std::wstring LastWriteTime; 
int getFileList(wstring filespec, tFoundFilesVector &foundFiles) 
{ 
WIN32_FIND_DATA findData; 
HANDLE h; 
int validResult=true; 

int numFoundFiles = 0; 
h = FindFirstFile(filespec.c_str(), &findData); 

if (h == INVALID_HANDLE_VALUE) 
    return 0; 

while (validResult) 
{ 
    numFoundFiles++; 
    foundFiles.push_back(findData); 
    validResult = FindNextFile(h, &findData); 
} 
return numFoundFiles; 
} 

void showFileAge(tFoundFilesVector &fileList) 
{ 
    unsigned int fileTime,curTime, age; 
    tFoundFilesVector::iterator iter; 
FILETIME ftNow; 
__int64 nFileSize; 
    LARGE_INTEGER li;  
li.LowPart = ftNow.dwLowDateTime; 
li.HighPart = ftNow.dwHighDateTime; 

CoFileTimeNow(&ftNow); 
    curTime = ((_int64) &ftNow.dwHighDateTime << 32) + &ftNow.dwLowDateTime; 

    for (iter=fileList.begin(); iter<fileList.end(); iter++) 
    { 
    fileTime = ((_int64)iter->ftLastWriteTime.dwHighDateTime << 32) + iter-      >ftLastWriteTime.dwLowDateTime; 

    age = curTime - fileTime; 

    cout << "FILE: '" << iter->cFileName << "', AGE: " << (INT64)age/10000000UL << " seconds" <<  endl; 
    } 
} 

int main() 
{ 
string fileSpec = "*.*"; 
tFoundFilesVector foundFiles; 
tFoundFilesVector::iterator iter; 

int foundCount = 0; 

getFileList(L"*.c??", foundFiles); 
getFileList(L"*.h", foundFiles); 

foundCount = foundFiles.size(); 
if (foundCount) 
{ 
    cout << "Found "<<foundCount<<" matching files.\n"; 
    showFileAge(foundFiles); 
} 
return 0; 
} 

的值它在這條線.....

Answer 1

的錯誤是在這裏：

curTime = ((_int64) &ftNow.dwHighDateTime << 32) + &ftNow.dwLowDateTime; 

dwHighDateTime和dwLowDateTime已經int類型。然而，你正在考慮他們的地址。因此，分配到curTime變成int指針。

你想是什麼：

curTime = ((_int64) ftNow.dwHighDateTime << 32) + ftNow.dwLowDateTime; 

第二期：

curTime和fileTime只有32位。你需要使他們成爲64位整數。
