Hi! I´m a newcomer with 10 years working in VB6 and MySql and very happy of finding jabaco. I want to create an inteface like the one I have in vb6. (see images). Any tips on how to work with MDI forms. And how put a TreeView in the main form. Thanks. http://imageshack.us/photo/my-images/31/pic02sc.jpg http://imageshack.us/photo/my-images/9/pic01ym.jpg
