Is there an API for VCD?

[Wurzel]

Hi,

I am writing a WPF program that will use VCD to mount ISO's. While I can get the basic's working I would like to add some slightly more advanced functionality including drive checks and error handling.

Thanks

There is the "vcdmount.exe" utility, which lets you mount / unmount / eject / open & close the drive door (of every drive, not only vcd).

type "start vcdmount" from a command prompt for a brief help.

Hi

Thanks for your reply.

This is what I am using at the moment. While it does do the things I want it to do I do run into a few problems.

For example.

The first thing my program does is issue an unmount command regardless of anything being mounted (its easier than trying to work out if something is already mounted). Then it mounts the ISO I am interested in and runs a program on that drive. The trouble is if there is an ISO mounted it unmounts, mounts but shows an error when running the program (Drive not ready, or words to that effect). This only happens if an ISO is already mounted. My program does wait for each of the command to complete before moving on so I assume there is a delay in the drive being ready when I have to do an unmount then mount. I have tried to put a sleep in my program so it waits a while but I still get the same problem. When the error is displayed I get a few buttons. Continue, Retry, Cancel, Abort. If I hit retry it continues as expected.

An API with the right functions would let me query the drives state to see if it is ready for me to move on to the next stage.

Windows offers you an API to detect, if a disc has arrived or has been removed. You'll receive a WM_DEVICECHANGE message, this should be easy to process.

This was the first thing I tried. Unfortunately this gives me a device ready but the error still appears. It is as if there is a slight delay in the OS thinking everything is ready and the drive actually being ready.

I have now got a bit of a work around, its not pretty but it works!
