Answer 2

不行,这个我都下载来试了,就是知道盘符后不知道DEVICEIOCONTROL函数里面的第二个该怎么设置

Answer 3

注册表里不就是有吗？还有SetupDi函数族也可以拿到。

Answer 4

hDevice = CreateFile(szBuf, GENERIC_READ,
FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, NULL, NULL); if (hDevice != INVALID_HANDLE_VALUE)
{ pDevDesc = (PSTORAGE_DEVICE_DESCRIPTOR)new BYTE[sizeof(STORAGE_DEVICE_DESCRIPTOR) + 512 - 1]; pDevDesc->Size = sizeof(STORAGE_DEVICE_DESCRIPTOR) + 512 - 1; if(GetDisksProperty(hDevice, pDevDesc))
{
szMoveDiskName[k] = chFirstDriveFromMask(temp);
szMoveDiskName[0]=k;
k++;
ShowMessage("\r\n找到U盘，名称:\r\n");
p= (char*)pDevDesc;
str = (pDevDesc->VendorIdOffset ? &p[pDevDesc->VendorIdOffset]:"(NULL)");
ShowMessage(str); ShowMessage("\r\n产品ID:\r\n");
str=(pDevDesc->ProductIdOffset ? &p[pDevDesc->ProductIdOffset]:"(NULL)");
ShowMessage(str);
ShowMessage("\r\n产品版本:\r\n");
str = (pDevDesc->ProductRevisionOffset ? &p[pDevDesc->ProductRevisionOffset] : "(NULL)");
ShowMessage(str);
ShowMessage("\r\n序列号:\r\n");
str = (pDevDesc->SerialNumberOffset ? &p[pDevDesc->SerialNumberOffset] : "(NULL)");
ShowMessage(str);
} delete pDevDesc;
CloseHandle(hDevice);
}

BOOL GetDisksProperty(HANDLE hDevice, PSTORAGE_DEVICE_DESCRIPTOR pDevDesc)
{
STORAGE_PROPERTY_QUERY Query;
DWORD dwOutBytes;
BOOL bResult; Query.PropertyId = StorageDeviceProperty;
Query.QueryType = PropertyStandardQuery; bResult = ::DeviceIoControl(hDevice,
IOCTL_STORAGE_QUERY_PROPERTY,
&Query, sizeof(STORAGE_PROPERTY_QUERY),
pDevDesc, pDevDesc->Size,
&dwOutBytes,
(LPOVERLAPPED)NULL); return bResult;
}
