This code may be extreamly inefficient and/or VERY POOR coding, because I don't know what to do :'( and like I want a Main window to come up and then a selection, button inputs that selection then a second window comes up and then a combobox and button (combobox to choose the drive) and then hit the button to input the selection, and then that selection is carried out... (NOTE: The 1==0 and 1==1 is just so it can run for now... yes... ghetto) SO any help?
Code:
