I'm is process to make an application in VFP 6.0. The requirement of the client is to make the software with top level form having two panes. the left pane shows the icons which are linked with some prime modules and the right pane is for displaying the actual entry screen (exactly same as the Microsoft Outlook)

Dbi Tech make a set of activeX controls that includes an Outlook style list bar. I have used this control with great success and it should work well for you.
