Click on the My.Settings link in my signature for more info. Change the scope to User and then add code that is something to the extent of:

Code:
My.Settings.History1 = "File1.txt"
My.Settings.History2 = "File2.txt"
My.Settings.History3 = "File3.txt"
My.Settings.History4 = "File4.txt"
My.Settings.Save()
