Can i use Table.Concat like this ?

[qwerty]

i find myself in the situation where i want to loop through a table reading the data from every other line in the table into a list box, so i was thinking to try using Table.Concat with no separator declared, and a matching index for the start and stop points.... would this effectively allow me to read just that one line ?


here is what i have so far


-- Transfer from chunkTable to List Box --
item_count = Table.Count(chunkTable);
ind = 1;
ListBox.DeleteItem("FileSizeList", LB_ALLITEMS);
for x = 1, (item_count/2) do
ListBox.InsertItem("FileSizeList", x, "Piece ".. x, Table.Concat(chunkTable, "", ind, ind));
ind = ind+2;
ListBox.SetUpdate("FileSizeList", true);
end



i'm not entirely sure if i need to use the SetUpdate thing or not, i only really need it to update at the end of the loop, but if it takes a while to populate then updating on each step could be handy

i also have the same data in a text file, but thought it might be easier to do it this way from the table

FYI, in the for statement, you can use step. Wouldn't that be easier?

sorry, you lost me i'm afraid .... but i did find an alternitive way of doing it...

in the original table, when it was created, there was a number of aditional characters and things in each index which i did not need, or wanted to change, so when i was creating the original table in the function i use for that, i make it create a second table with only the data i needed in each element plus the aditional text i wanted, so now i can use this

-- Transfer Data from chunkSizeTable to List Box --
item_count = Table.Count(chunkSizeTable);
ListBox.DeleteItem("FileSizeList", LB_ALLITEMS);
for j,k in chunkSizeTable do
ListBox.InsertItem("FileSizeList", j, "Piece ".. j, k);
ListBox.SetUpdate("FileSizeList", true);
end

Use a loop with a step is what yosik was suggesting

-- A for loop that counts from 1 to 10 in 2's
min = 0; -- The number to start at
max = 10; -- The number to stop at
step = 2; -- The number to count by (in this case 0, 2, 4, ...)
for count = min, max, step do
-- Do something here
end

and yes, that would have worked better than what i had, but writing a second table on the fly with the first one has actually allowed me to alter the way i display the data which is better for me :) live and learn as they say


ok, so thats this one solved ... appreciate the help guys, and i will certainly remember this for next time :)


now to find out why my File.GetSize action is returning a value lower than 250mb when applied to a 4.09gb img file :(... back to the search engine i go !
