I tried this and it doesn't detect any CD inserted or removed.

Is it complete?

Thanks.


threadomancy; 2.) I've fixed your quote/code tags.

Hi

This example Detect USB device insertion
It is the same function DBT_DEVICE

Or your can make with IO_Ctl and a Timer

.const
IOCTL_STORAGE_CHECK_VERIFY  equ 002d4800h
IOCTL_STORAGE_CHECK_VERIFY2 equ 002d0800h

invoke GetCDHandle,CTEXT ("\\.\F:")
.if eax !=0
invoke VerifyMedia,hDevice
.if eax==TRUE
invoke SetDlgItemText,hWnd,1003,CTEXT ("CD Found!")
	.else
	invoke SetDlgItemText,hWnd,1003,CTEXT ("No CD Found!")
	jmp @F
.endif

GetCDHandle  proc lpszDevice:DWORD
	invoke CreateFile,lpszDevice,GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, 0, NULL
    .if	eax != INVALID_HANDLE_VALUE
        mov  hDevice,eax
      .else
        mov eax,FALSE
    .endif      
	ret
GetCDHandle endp

VerifyMedia Proc _hDevice:DWORD
LOCAL dwBytes:DWORD	
	invoke DeviceIoControl,_hDevice, IOCTL_STORAGE_CHECK_VERIFY2, NULL, 0,0, 0, addr dwBytes, 0
	.if eax!=0
         mov eax,1
	  .else
           mov eax,0
    .endif
    ret
VerifyMedia endp

This is a part of my CD ripper project and is tested.
