Re: [Gambas-user] A random sort of listview
Hi yourself! Here is the problem in the code: FOR i = 0 TO ListView1.Count - 1 ' write items in listview2 TRY PRINT myArray[i] listview1.MoveTo(myArray[i]) TRY c = listview1.Item.Key TRY PRINT myArray[i], listview1.item.key , c, counter i: , i, total count: , listview1.Count TRY listview2.add(c, listview1.item.text) NEXT When the counter i reaches Listview1.Count -1 it gives an error and does not write the last record!

Re: [Gambas-user] A random sort of listview
You were correct! There was a extra comma in the data file that was breaking the loop! BTW to you an everyone else if you celebrate it, Happy Easter! If not ignore me. ;) JB SKaggs Simonart Dominique wrote: Hi again :) May be you did not see the last sentence of my answer wich is written in 3 places? Your code is just fine and I don't have any problem with the ListViews. Of course, I had to initialize the ListView1 with my own data like this: FOR i = 0 to 21 ListView1.Add(Str(i), number Str(i)) NEXT After that, I run your code and all is fine! If you have problem, this is therefore with the content of your Listview1. I think it is not correct to have identical keys in a ListView because if I attempt to do it the program stop immediatly. I even don't understand how you could get this situation! Here is what I tried: FOR i = 0 to 21 SELECT CASE i CASE 0 ListView1.Add(5, number Str(i)) CASE 1 ListView1.Add(13, number Str(i)) CASE ELSE ListView1.Add(Str(i), number Str(i)) END SELECT NEXT this code stop with i=5 and say that the key is already used!

And perhaps, as the algorthm is different, it could solve the problem of missing records (which I didn't understand...). Cheers, = I resend my message because it seems the text is missing?! :-\ This is not really a problem. The Randomizing process could be explained like this: 1) You align a sorted card deck in front of you on a table 2) then, from all the cards on the table you take a random card in your hand so there is a place without card on the table 3) you put the last card on the table in this hole, so the hole is now at the last place 4) you continue by returning to 2 until you got all the cards in your hand Now you have a randomized deck of cards in your hand 5) you put the first card you got in the last place on the table and continue to do that until you have no card in your hand. Now the randomized deck of cards is on the table. If you examine carefully this process, you will remark that each time you filled a hole with the last remaining card on the table, you could place the card you got just before in the last place, because it is free! You only have to remember to not take these cards already selected. So you could do the 5) between 3) and 4) and this is exactly which is done by the SWAP instruction! It is true that some places will be selected several times, but their content change each time (there is another card on these places each time). In no way you could loose a card in this process!!. The JBskaggs' problem, I think, is that, before he starts the process, there are twice 2 identical cards in his deck and Gambas does not admit that, so when Gambas encounters the duplicated cards it reject them, (but since TRY is used, you don't see the error!!) and finally, 2 cards are missing.
