yes, every pass. sorry, but I don't understand what you mean...... maybe I have to explain my project better.. at the begining, I have 3 slideshows, 3 files "*.exe". the first have only one picture, with two links (button) included. the links open 2 differents big slideshows. From them, I want to make only on file "*.exe". so, I like to have in my unique file "MySlideShow.exe": 1) the first slide (page 1) contain two button with two links. one to slideshow A, one to slideshow B. 2) page 2, this slide is the first of the slideshow A. End of slideshow A at slide n° 30. 3) page 31, this slide is the first of the slideshow B. End at slide n°48. 4) I want when user push button to go on slideshow A, the slideshow have to run slides from n° 2 to n° 30 (this is easy to make) and at slide n°30, the slideshow comeback everytime automaticaly ( without any manual action) to slide n°2. the user don't have to do anything. 5)when user push button to go on slideshow B, the slideshow have to run slides from n° 31 to n° 48 (this is easy to make) and at slide n°48, the slideshow comeback everytime automaticaly ( without any manual action) to slide n°31. the user don't have to do anything. .................... is it ok? I want to make that because I want the user have only on file, the file could be launched by autorun. many thanks for all .... eric.
