Thank you for your easy solution. I'll give it a try.

It does not seem to work as required. However the biggest problem here is that executions won't suspend at breakpoints. Debugging is very troublesome!

Your solution sets hidden permanently. As I already have hidden slides, I don't want to mix with them or by accident unhide a slide I have originally set to hidden. A better solution for my application would be to set the next active slide to i+2. I suppose I'd better use App_SlideShowNextSlide instead but then, how I set the next slide number to ActiveSlide + 2?
