i have 2 lists which are filled with filenames

now the 2 lists are never filled with the same amount of items
but what i have to do is compare the 2 lists and find out if any items match and then remove them from the 2nd list

sorry if this has already been covered but i couldn't find any posts in the forum

my brain is on holiday today and i can't figure it out Embarassed

thankyou!

Code:

rem A couple of lists
  list create,1
  list loadtext,1
"Item 1
"Item 2
"Item A
"Item B
"Item 3
"Item 4

  list create,2
  list loadtext,2
"Item A
"Item B
"Item C
"Item D

rem A loop to compare list items
  %x = @count(1)
  %c  = 0
  repeat
    list seek,2,0
    %M = @match(2, @item(1,%c))
    if %M
      rem If we have a match in list 2 from list 1, delete the item in list 2
      list seek,2,@index(2)
      list delete,2
    end
    %c = @succ(%c)
  until @equal(%c,%x)

  rem Clean up
  list clear,2
  list clear,1
  list close,2
  list close,1



This might help. It's a very simple demo, so if you get more advanced
with this than it is, you need to add more error handling.

Happy coding... Cool

Take a look in the "Visual DialogScript Open Source Projects" section of this Forum. I had posted a "Benchmark" program some time back which has similar functionality to what you may be looking for.

It uses lists to store all the file names on a disk drive and shows you what files have been added since you last ran it. (Used to detect the installation of unwanted/Unauthorized software).
