I managed to run files....I placed a MessageBox to check what the path was of the SelectedNode....It turned out not to be the Full Path but a Folder in the tree. So I added also the string of the rootpath to that Folder.... Anyway it is running files now....however only known filetypes....when a filetype is not associated to a program by windows I get an error...is it difficult to solve that? also folders are listed in the ListView.....when I double click them....an external explorer window of the selected item is opened outside my application....but the ListView should work like an explorer too....so it must browse when a folder is double clicked and it should run when a file is selected... What is the difference between: ListView1.FocusedItem and ListView1.SelectedItems[0] ? Thanx for helping me out sofar....I am a beginner in programming. -- modified at 6:33 Tuesday 30th October, 2007
