i want to create a dropdownlist to store information of the scene, like objects names, and delete selected object name when i want.
the main idea of this is to save this data to a file in order to read that again when open 3dsmax .
i hope some one can help me with this
I write this to a file from the dropdownlist
items=#(“Item 1”, “Item 2”, “Item 3”, “Item 4”)
but when I read this back, I have as result
“Item 1”
when i want to have only
Item 1
I don’t want to have the “” in the name
please help me with this, iam using this to write
format ” %
” (“ITEMS=” + (ddlst.items) as string) to:newTXT
It will always return a string, no way around it. However, it appears that is what you need as strings are the only thing that can be written out to a file. I am not sure what the problem is from what you posted.
If you really need to remove the values from the string use execute.

the problem is when I read the info back, the dropdownlist have item like this
Item2
when save the data, the data in the txt have this
“Item 2”
so when i red the data from the txt i have this back in the dropdownlist
“Item 2”
and the problem is when I save the data again because, save
““Item 2″”
is there any form to take back the data from the txt without the “” to have this clean
thanks
You could use something like:
str = "\"Item 2\""
(filterstring str "\"")[1]

finally I do that I want with this, i know that maybe there is a better and optimized form to, so if someone show me how I appreciate the help
the only problem that i have is, that i only can store items previously made in the write part of the txt
– READ THE INFO
in_text = openfile “C:\TEMP\ObjectSelection.txt”
skipToString in_text “,”
while not eof in_text do
(
str = readDelimitedString in_text ","
(filterstring str ")")[1]
destino.items = append destino.items ((str) as string)
)
close in_text
–WRITE THE INFO
if (newTXT = createFile "C:\\TEMP\\ObjectSelection.txt") != undefined do
(
(
format "%
” ((“,” + destino.items[1]) + (“,” + destino.items[2]) + (“,” + destino.items[3]) + (“,” + destino.items[4]) + (“,” + destino.items[5]) + (“,” + destino.items[6]) + (“,” + destino.items[7]) + (“,” + destino.items[8]) + (“,” + destino.items[9]) + (“,” + destino.items[10]) as STRING) To:newTXT
flush newTXT
)
close newTXT
)
)
-- READ THE INFO
if (ss = openfile "C:\\TEMP\\ObjectSelection.txt") != undefined do
(
destino.items = execute (readline ss)
close ss
)
--WRITE THE INFO
if (ss = createFile "C:\\TEMP\\ObjectSelection.txt") != undefined do
(
format "%
" (with printAllElements on destino.items as string) to:ss
flush ss
close ss
)
that is really optimized thanks, but i have only a problem with that i need something like this
in my script i write the TXT file like this
,ITEM1,ITEM2,ITEM3,ITEM4
and in the optimized script I have this in the TXT
#(“ITEM1”, “ITEM2”,“ITEM3”,“ITEM4”)
I need to write the dropdownlist without the “” to have a clean data to put it back in the dropdownlist
What Denis posted will work. When you read the array you’ll get a string:
“#(“ITEM1”, “ITEM2”,“ITEM3”,“ITEM4”)”
Then you use the execute() method to convert the string to an array:
#(“ITEM1”, “ITEM2”,“ITEM3”,“ITEM4”)
At that point you can just add the strings to the drop down list.
the problem is when I read the data back, the drop list take the items back but like this “ITEM 1”
and I need to have ITEM 1
Yes… it’s a string. When you add it as an item to the drop down list it will display as Item 1, NOT “Item 1”
If that’s not the case then post your script, because you’re either reading or writing it wrong.
you are right, I am doing bad the script, thanks for all denisT, PiXeL_MoNKeY and labbejason
this site is full of genius XD
only two question
-how can I select an item from the dropdownlistm for example, if I add a new item to the dropdownlist, how can I set the dropdownlist in that item.
-and if the item exist select the item istead of adding one new
thanks for al guys
From the maxscript help on dropdownlist:
<dropdownlist>.selection Integer
The currently selected item number, 1-based. If the items list is an empty array, this value is 0.
<dropdownlist>.selected String
The text of the currently selected item. Can be set to replace individual items without resetting the entire items array. If the items list is an empty array, this value is undefined.
I would look at working with arrays in the maxscript help. There are all kinds of ways to search and filter items.
findItem <array> <value>
Does a MAXScript ‘==’ comparison between elements in the array and the target object and then returns the index of the first occurrence of the given value in the array or zero if the value is not in the array.
Values such as Point3s and Strings match if they have the same contents.
So put a finditems in an if loop where if != 0 set the .selection to the found value.
