I have a VB project that opens PowerPoint presentations and runs the chosen slides in slide show mode on a dual-monitor system (the VB application on one and the slide show on the other). When a slide is clicked on the VB monitor, it's highlighted (with a black rectangle around it) and when Page up and Page down are pressed on the keyboard the next/previous slide are shown on the slide show monitor. I need the slide to be highlighted that is up on the slide show monitor when page up and down are pressed. Does anybody know how I could do this (if this makes any sense to anybody!)? Thanks in advance.
