I am developing a form for the user Interface and I want to give user an ability to browse file/dir/drive list box to choose the file as an input. I don't know how to synchronise all three controls to work together on the form. I have following three controls on my form.
1) DriveListBox
2) DirListBox and
3) FileListBox
If I get the code sample from somebody for this, I will really apreciate it.

Thanks,
Pshah
