光碟機拖盤的退出與關閉方法
void __fastcall Tfrm_main::OpenCD()
{
char *rtnstr;
mciSendStringA("set CDAudio door open", rtnstr, 0 ,0);
try_icon->SetIconIndex(1);
ifOpen = true;
//以下加入您的程式碼
} void __fastcall Tfrm_main::CloseCD()
{
char *rtnstr;
mciSendStringA("set CDAudio door closed", rtnstr, 0, 0);
try_icon->SetIconIndex(0);
ifOpen = false;
//以下加入您的程式碼
} 以上在 Win9x/Win2000 下執行無誤 網路志工聯盟----Visita網站http://www.vista.org.tw

axsoft 使用的是呼叫API 中的MCI類方法
我另外提供一種方法，是叫用ASPI Use_EXEC_SCSI_CMD(Select_Device_Count,0x1b,4,2,0);
Use_EXEC_SCSI_CMD(Select_Device_Count,0x1b,4,3,0);
TForm1::Use_EXEC_SCSI_CMD(int PA, int PATAPI_COMMAND, int PSelect_Byte, int PSelect_Byte_Code, int PGet_Data_Byte)
{
memset( &srbExec, 0, sizeof(SRB_ExecSCSICmd) );
srbExec.SRB_BufLen = 0;
srbExec.SRB_BufPointer = 0;
heventSRB = CreateEvent( NULL, TRUE, FALSE, NULL );
srbExec.SRB_Cmd = SC_EXEC_SCSI_CMD;
srbExec.SRB_Flags = SRB_DIR_IN || SRB_EVENT_NOTIFY;
srbExec.SRB_Target = iTarget;
srbExec.SRB_SenseLen = SENSE_LEN;
srbExec.SRB_CDBLen = 12;
srbExec.SRB_PostProc = (LPVOID)heventSRB;
srbExec.CDBByte[0] = PATAPI_COMMAND;
srbExec.CDBByte[PSelect_Byte] = PSelect_Byte_Code;
dwASPIStatus = pfnSendASPI32Command( (LPSRB)&srbExec );
}

To turboted: 您的 ASPI專文準備了如何？何時可發表?我們還在期待喔! 對了ASPI偵測光碟如何使用?(如光碟進片否?/光碟材質/製造廠...),
另一個就是光碟機的機器能力資訊如何偵測?...:) 網路志工聯盟----Visita網站http://www.vista.org.tw

我是個初學者，就算是很簡單的程式，要讓他會動也得弄很久
我將我操作的程式寫下： 一、裏頭很多的變數，可以不要，我根本弄不清楚是用來做什麼的 二、mciSendStringA 使用到 winmm.dll，需要 include mmsystem.h進來 #include

其實用MCI 寫CDROM的動作程式並沒這麼難，只是，功能有限
就您說的mciSendStringA ，其實你可以去看看他的原型
在msdn上面可查..
一共有四個參數，分別是 ByVal lpstrCommand As String String控制命令
可用的String 列表
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/mmcmdstr_4nub.asp
ByVal lpstrReturnString As String String回傳值
ByVal uReturnLength As Long Long回傳長度
ByVal hwndCallback As Long Handle to a callback window if the "notify" flag was specified in the command string 附帶這裏有MCI的爸爸
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/mci_7vvt.asp 再來關於我的ASPI..HMM..目前可愛的小旻正忙著和DMA&PIO MODE For Dos
努力，所以，還要再給他等那麻『一下下』...
