write a subrountine that
1. opens the file
2. reads the contents and add it to the listbox line by line
You can either add the row contents direct to the listbox using
dim ReadLineFromFile as string = file.readline
listbox1.items.add(ReadLineFromFile)
or you can create either a datatable / generic list to store the details in from all the files and then add it to the the listbox1's datasource
3. close the file
and repeat for the remaining files that you want to import.
