I can gain access to a tape drive with createfile - then can load, unload, position tape, rewind - all work fine - everything except Read. I have tried both BackUpRead and ReadFile with no success - also tried the standard example by Ethan from this forum - same problem.
( I can read the tape via ASPI- but its way too slow )

Does anyone have ideas ?

Thanks

ps OS is Win 2K SP5, language is VB6

Do you get any error(s) when trying to read using ReadFile?

Make sure you specify the last parameter as ByVal 0& if you didn't use FILE_FLAG_OVERLAPPED in CreateFile...

Post your code...

I was working on a PowerPoint add-in the other day and a client asked me "can you implement a feature which processes a chart when it's pasted into a slide from another deck?". It got me wondering how to hook into built-in ribbon events in Office.
