我有一個函數WINAPI C++獲取當前物理驅動器號
DWORD GetPhysicalDriveSerialNumber(UINT nDriveNumber, CString& strSerialNumber)
{
DWORD dwResult = NO_ERROR;
strSerialNumber.Empty();
// Format physical drive path (may be '\\.\PhysicalDrive0', '\\.\PhysicalDrive1' and so on).
CString strDrivePath;
strDrivePath.Format(_T("\\\\.\\PhysicalDrive%u"), nDriveNumber);
// call CreateFile to get a handle to physical drive
HANDLE hDevice = ::CreateFile(strDrivePath, 0, FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL, OPEN_EXISTING, 0, NULL);
if (INVALID_HANDLE_VALUE == hDevice)
return ::GetLastError();
// set the input STORAGE_PROPERTY_QUERY data structure
STORAGE_PROPERTY_QUERY storagePropertyQuery;
ZeroMemory(&storagePropertyQuery, sizeof(STORAGE_PROPERTY_QUERY));
storagePropertyQuery.PropertyId = StorageDeviceProperty;
storagePropertyQuery.QueryType = PropertyStandardQuery;
// get the necessary output buffer size
STORAGE_DESCRIPTOR_HEADER storageDescriptorHeader = { 0 };
DWORD dwBytesReturned = 0;
if (!::DeviceIoControl(hDevice, IOCTL_STORAGE_QUERY_PROPERTY,
&storagePropertyQuery, sizeof(STORAGE_PROPERTY_QUERY),
&storageDescriptorHeader, sizeof(STORAGE_DESCRIPTOR_HEADER),
&dwBytesReturned, NULL))
{
dwResult = ::GetLastError();
::CloseHandle(hDevice);
return dwResult;
}
// allocate the necessary memory for the output buffer
const DWORD dwOutBufferSize = storageDescriptorHeader.Size;
BYTE* pOutBuffer = new BYTE[dwOutBufferSize];
ZeroMemory(pOutBuffer, dwOutBufferSize);
// get the storage device descriptor
if (!::DeviceIoControl(hDevice, IOCTL_STORAGE_QUERY_PROPERTY,
&storagePropertyQuery, sizeof(STORAGE_PROPERTY_QUERY),
pOutBuffer, dwOutBufferSize,
&dwBytesReturned, NULL))
{
dwResult = ::GetLastError();
delete[]pOutBuffer;
::CloseHandle(hDevice);
return dwResult;
}
// Now, the output buffer points to a STORAGE_DEVICE_DESCRIPTOR structure
// followed by additional info like vendor ID, product ID, serial number, and so on.
STORAGE_DEVICE_DESCRIPTOR* pDeviceDescriptor = (STORAGE_DEVICE_DESCRIPTOR*)pOutBuffer;
const DWORD dwSerialNumberOffset = pDeviceDescriptor->SerialNumberOffset;
if (dwSerialNumberOffset != 0)
{
// finally, get the serial number
strSerialNumber = CString(pOutBuffer + dwSerialNumberOffset);
}
// perform cleanup and return
delete[]pOutBuffer;
::CloseHandle(hDevice);
return dwResult;
}
我想目前的驅動器號 示例(位於程序的驅動器號)(我的系統): 如果我將運行porgram在磁盤c它必須返回0(hdd 0) 如果我將在磁盤d或e上運行progrman它必須返回1(hdd 1) 閃存驅動器2等 我該怎麼做?
這是相當多的代碼...你能更具體問題出在哪裏?這將增加的機率會有人能夠提供一個有用的答案(不像這一個) – Jaap
我剛纔的情況下添加該代碼爲人們理解我爲什麼要發在功能驅動器號(要獲取驅動器ID序列號)理想我願做這樣的事情GetPhysicalDriveSerialNumber(驅動器號GETED前FUNCCCALLED,Str_to_save_hhd_serial_numb) –
如果你的程序在運行位置與此類似'\\服務器\ sharename'? – milevyo
