Checking items in a list

[tupac]

how do you check if an item in a list is the same as another item in the same list?
ex:
_____________
|item1 < same |
|item2 |
|item3 |
|item1 < same |
| |
|____________|

o, and also, if the 2 items are the same, how do you get rid of the latest one that showed up.

[pavol]

well you could use a for loop to cycle through the data in the list like this;

code:

For i = 0 To lstList.ListCount - 1     For j = i + 1 To lstListCount         If lstList.List (i) = lstList.List (j) Then             lstList.RemoveItem (j)         End If     Next j Next i

i only hope this code works cuz i just thought it up. if it doesn't it should be something like what i just wrote.
anyways, i hope it helps

well... that didnt help much... but i do get where ure comin from. may-b im duin it worng... i setup a timer w/ an interval of 1, and put ure code in the Private Sub Timer2_Timer()... is that how its supposed to work?? anyway, thnx for what u gave me so far... just tell me if wat im duin is rite (puttin it into a timer), and if so then ill try 2 tweak some more with it...

i should think that's pretty much right to put it in a timer. makes sense, but you don't really need to check it that often. try putting the code after your code that adds an item to the list
so, something like this:

code:

lstList.AddItem whatever For i = 0 To lstList.ListCount - 1     For j = i + 1 To lstListCount         If lstList.List (i) = lstList.List (j) Then             lstList.RemoveItem (j)         End If     Next j Next i

so taht means as soon as the user adds an item that's the same as another item in the list it should be taken away

[cool dude]

yes pavol has the right idea! NO do not use a timer there is absolutely no point at all to use a timer in this case

[tupac]

well, actually there is a point... cuz im workin on a multi-user chat program, and i need to check if new users are loggin on very frequently.

[pavol]

well if you need it to be checked every so often then put the code in a timer, but i still think that you could do without it

[tupac]

well, wat i did is after i send the msg (name) i do the code:

code:

For i = 0 To lstNames.ListCount - 1         For j = i + i To lstNames.ListCount             If lstNames.List(i) = lstNames.List(j) Then                 lstNames.RemoveItem (j)             End If         Next j     Next i

and now it doesnt clogg up the list... but the words continue on down for about 4 - 5 lines... and they go in a line like so:

code:

____________ |ddkddkddk....| |ddkddkddk....| |ddkddkddk....| |ddkddlkddk...| |___________|
