I think its not good way but he can uses of SetCurrentDirectory check return value if its nonzero it has floppy.
But you have to poll regularly for that.. i don't think thats good design and could present user headache, as if floppy is corrupt, it could hang the system!

Actually Floppy Drive doesn't work the way CD Drive work. I mean, you could simply put Floppy in the drive, but to make Computer aware you have to click on floppy icon, which is not in case of cd drive. thats just my logical conclusion!

PC floppy drives have (or used to have) a active low Disc Change line, which went high (
1) when the drive was empty and was low (0) when a disc was inserted. Not sure if/how you can get direct access to that line on Win32, though... Maybe there is an LVM routine that can be used? Peace!-=- James

Any thing for you sir :) Actaully I tried this for one of my project requirment. I used the
ExecNotificationQueryAsync()function with the following query.HRESULT hres = pSvc->ExecNotificationQueryAsync( _bstr_t("WQL"), _bstr_t("SELECT *" "FROM __InstanceOperationEvent WITHIN 1 " "WHERE TargetInstance ISA 'Win32_LogicalDisk'"), WBEM_FLAG_SEND_STATUS, NULL, pStubSink );And in the notification handler we can check the instance is __InstanceCreationEvent and __InstanceDeletionEvent for any drive arrival or removal. But if you want disk arrival or removal you may need to handle the __InstanceModificationEvent( this one i didnt check ).nave [OpenedFileFinder]
