盘符

查找所有的盘符，并且只显示可移动磁盘，也就是U盘

/*** find all drivers and show removeable drivers*/void CUkeyKitDlg::FindAllDrivers(){        CComboBox* Driver=(CComboBox*)GetDlgItem(IDC_COMBO1);        Driver->ResetContent();        DWORD dwNumBytesForDriveStrings;//实际存储驱动器号的字符串长度        HANDLE hHeap;        LPSTR lp;        CString strLogdrive;       //获得实际存储驱动器号的字符串长度        dwNumBytesForDriveStrings=GetLogicalDriveStrings(0,NULL)*sizeof(TCHAR);       //如果字符串不为空，则表示有正常的驱动器存在        if (dwNumBytesForDriveStrings!=0) {        //分配字符串空间        hHeap=GetProcessHeap();        lp=(LPSTR)HeapAlloc(hHeap,HEAP_ZERO_MEMORY,dwNumBytesForDriveStrings);       //获得标明所有驱动器的字符串        GetLogicalDriveStrings(HeapSize(hHeap,0,lp),lp);        //将驱动器一个个放到下拉框中          char s[40];        while (*lp!=0) {            UINT nDriveType = GetDriveType(lp);            if (nDriveType == DRIVE_REMOVABLE){               sprintf(s, "%s (%c:) %d MB", "可移动驱动器", lp[0],getTotalSpace(lp) );               //驱动器是这样的 c:\ d:\ 所以只取第一个字符               Driver->AddString(s);            }            lp=_tcschr(lp,0)+1;        }    }}

磁盘号

通过盘符，获取磁盘号

自己写的grubist.exe 的界面

由于使用的是1.1版本，所以属于一次开发，使用的可以去这里下载想http://download.csdn.net/detail/li740207611/9595323
