ejecting cdrom

is there any tutorial that explains how eject cdrom? can you help me thanks

The mciSendString is a good way to open a cdrom.......you can find examples on this board if you look..... dont forget the winmm.lib when linking...

Also the DeviceIoControl() API can open these drives....

Here's something I was messing with a while back..its not as good as using mciSendString(), but it kept me entertained for a little while :).........it works on Win2000 and probably therefore XP, but I dont think it will work on Win98.....anyway...it uses an API to give a bitmask of all drives available, and then tests them to see if they are CDROMs....then it opens a handle to the drive (I think this is where it would fail with Win98) and uses DeviceIoControl() to open the drive. Its not very good, but I thought I'd post it anyway :) ...have a look

That's sweet!! haha!! Why is it the stupid stuff that makes me so damn happy?

I dunno, but bumping threads makes me unhappy
