void ctrl_cdrom_door(

LPCTSTR drivename ,//光驱的盘符,如f:等.

bool fOpen//弹出时用true,弹入时用false

)

{

TCHAR devstr[128],ctrlstr[128];

wsprintf(devstr,_T("open %s type cdaudio alias mycd wait"),drivename);

wsprintf(ctrlstr,_T("set mycd door %s wait"),fOpen?_T("open"):_T("closed"));

mciSendString(devstr,NULL,0,NULL);

mciSendString(ctrlstr,NULL,0,NULL);

mciSendString(_T("close mycd wait"),NULL,0,NULL);

}


ctrl_cdrom_door("L:",true); //打开光驱
ctrl_cdrom_door("L:",false); //关闭光驱

这个是打开指定盘符的,在上面的基础上,下面的可以打开第几个光驱,不用指定光驱盘符

void Cdopen(int cdn) //打开第cdn个光驱
{
// TODO: Add your control notification handler code here
int i,cdnum=0;
char str[3];
for(i=0;i<10;i++)
{
    str[0]='A'+i;
    str[1]=':';
    str[2]='\0';
    if(DRIVE_CDROM==GetDriveType(str))
     cdnum++;
    if(cdnum==cdn)
    {
     ctrl_cdrom_door(str,true);    //打开光驱
     break;
    }
}

}

void Cdclose(int cdn) //关闭第cdn个光驱

{
// TODO: Add your control notification handler code here
int i,cdnum=0;
char str[3];
for(i=0;i<10;i++)
{
    str[0]='A'+i;
    str[1]=':';
    str[2]='\0';
    if(DRIVE_CDROM==GetDriveType(str))
     cdnum++;
    if(cdnum==cdn)
    {
     ctrl_cdrom_door(str,false);    //关闭光驱
     break;
    }
}

}
