Hi Esteban,
If all you need to do is to extract/print the contents of all your TreeView nodes you can do something like this:
DIMENSION aArray[ THISFORM.TreeView.Nodes.Count ]
FOR x = 1 TO THISFORM.TreeView.Nodes.Count
aArray[ x ] = THISFORM.TreeView.Nodes(x).FullPath
ENDFOR
In the above code, all of the nodes values are loaded into an array. You can take this array and maybe place its contents in a table which you can then turn around and run a report from.
