判斷驅動器屬性(十三)

本文講述如何獲取系統盤符，然後判斷其屬性。

1.      創建一個對話框工程：DriverAttri

2.      添加一個下拉列表框，響應SelectChange消息，如下：

       CStringitemstr;

       inticursel=m_drivercomb.GetCurSel();

       m_drivercomb.GetLBText(icursel,itemstr);

       switch(::GetDriveType(itemstr))

       {

       case 2:

              m_type.SetWindowText("軟驅");

              break;

       case 3:

              m_type.SetWindowText("固定硬盤");

              break;

       case 5:

              m_type.SetWindowText("光驅");

              break;

       case 4:

              m_type.SetWindowText("網絡驅動器");

              break;

       case 6:

              m_type.SetWindowText("RAM");

              break;   

       default:

              m_type.SetWindowText("未知");

              break;

       }

3.      OnInitDialog()中添加代碼如下：

       size_talldriver = ::GetLogicalDriveStrings(0,NULL);

       _TCHAR *driverstr;

       driverstr = new_TCHAR[alldriver+sizeof(_T(""))];

       if(GetLogicalDriveStrings(alldriver,driverstr) != alldriver-1)

              returnFALSE;

       _TCHAR *pdriverstr = driverstr;

       size_tdriversize = strlen(pdriverstr);

       while(driversize>0)

       {

              m_drivercomb.AddString(pdriverstr);

              pdriverstr+=driversize+1;

              driversize=strlen(pdriverstr);

       }

完成。
