Dear Programmers

i have been commited for developing a vedio compression program using logitech webcam. when i install the logitech a dll will be included in the system for compress the avi file.

in that dll when i try to use the compress function it ask for 3 arguments.

1. inputfilename as string
2. outputfilename as string
3. eProgressCallBack as IProgressCallBack

any one will help me to know about the iprogresscallBack

thanks in advance

It's is almost certainly an class event interface, which raises an event against an API callback function. Sadly, however, you will need to get some documentation from Logitech on how it might be used, as it is not a standard (i.e. known) WIN32 callback.
