教你如何编写U盘 查杀程序

是一个抢先删除autorun.inf文件的例子，比360快，其实知道这个东西其他的就基本知道了，可以自己查SDK
UINT GetDriveFromMask(ULONG unitmask)
{
char i;
for (i = 0; i < 26; ++i)
{
if (unitmask & 0x1)
break;
unitmask = unitmask >> 1;
}
return (i + 'A');
}

LRESULT CHotkeyDlg::DefWindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
if(message == WM_DEVICECHANGE)
{
CString str;
DEV_BROADCAST_HDR* dhr = (DEV_BROADCAST_HDR *)lParam;
switch(wParam)
{
case DBT_DEVICEARRIVAL:
if(dhr->dbch_devicetype == DBT_DEVTYP_VOLUME)
{
PDEV_BROADCAST_VOLUME lpdbv = (PDEV_BROADCAST_VOLUME)dhr;
str.Format("%c:\\autorun.inf",GetDriveFromMask(lpdbv->dbcv_unitmask));
DeleteFile(str);
AfxMessageBox(str);
}
break;
default:break;
}
}
return CDialog::DefWindowProc(message, wParam, lParam);
}
