Yes it's difficult and the first goal is not to make a very powerfull tool
in a first step.

The switch is not done ... i know that but i've less time in this last days.

I think you will not be able at term to do program page switching... a
gambas report is a static desingned system... but i will explain to you how
to do that.




Take a look at  the Jasper reports engine! It really is complicated, works
