Procedure

To populate a Combo Box or List Box, simply set its .Choices to a table of values. For example, if you had a combo box called 'myComboBox', the following script would populate it with 3 strings ("value1", "value2", and "value3"):

local exampleTable = {"value1", "value2", "value3"}
Controls.myComboBox.Choices = exampleTable

Another example is to use dir.get() to get all of the audio file names in a directory and then put them into a Combo Box or List Box. You could do this by creating a table of files and then setting the .Choices of the control to that table as seen below:

directory = "media/Audio/Test"
temp = dir.get(directory)
fileTable = {}

for i,v in ipairs(temp) do
  table.insert(fileTable, directory.."/"..v.name)
end

Controls.Files.Choices = fileTable
