I would like to create a custom copy dialog window
and would need the copy info that is going on (size to copy, copy progress, file location and destination ect)

Is there a way to modify or watch for a windows copy dialog window?

How could i do this?

Thanks,

I think you should have a look into ICopyHook interface. Shell extensions implement that interface.

The shell calls the ICopyHook::CopyCallback method prior to performing one of these operations. This lets you customize the way operations are performed. Also you can prevent the operation.

The hwnd parameter of the only callback function would let you add any user interface elements you need to display.

Other parameters give you information about the source and destination etc and some flags too.

forgot to mention that the operations are move, copy, rename, or remove.

In other words you create a COM dll, that implements ICopyHook interface. You register that dll as an extension using Registry keys, and each time an operation occurs you get notified of it and do whatever you want.

My read of the docs indicates that ICopyHook gets a callback only for attempts to copy, move, etc. FOLDERS, and so I think it would not be too helpful for individual files.
