Can a Session Variable have multiple values?

[howardtlcc]

I want to have a Session variable that has multiple values that can be read from a script. Can this be done? I could always create my own separator and parse it out but I want to find the easiest way...

Related question... Can the combobox or listbox choices be populated via Script? I need to present a list of choices to the user and these choices are not known until the user runs the program and script determines the valid values?

thanks,

you can always change the value of a session variable, but I doubt you can have an array as a session variable. Not sure though.
Why not normal variables?

As for filling list/combo boxes with a script, that's possible.
See for example the help file about DlgListBox.AddItem or .InsertItem

I want to be able to have a session variable that has a variable number of version numbers (like 6.5,5.0,4.0). Then I need to parse these into a table (array). I got something going in script to do the parsing but was hoping there was a more native way to do this. Such as:

Suppose I had a session variable called %versions% and then in code I could declare a table like:

sessionvar = get the value of the session variable...
myversions = { .. sessionvar .. }

Is there some way to evaluate the string as code at runtime?

I think it should be done with some scripting, don't see a direct way.
If versions are like 6.5,5.0,4.0, a simple way would be to replace comma with CR+LF, save to txt file and read that file to a table with TextFile.ReadToTable()

BTW it's amazing that there is no built-in function to create a table from a string but only from a txt file, and that it's not possible to specify another separator.

ok, thanks, I just parsed the string into an array.

I agree, a way to split a string into a table would be great...

Well, we have DelimitedStringToTable() for this, kindly made by the Indigo Rose staff...

--[[
Function: DelimitedStringToTable
Purpose: Breaks up a string given a delimiter into a table
Arguments: DelimitedString - The string to parse
           Delimiter - The delimiter
Returns: A numerically indexed table with the string elements
Example:

string = "Brett,Mark,Darryl,Lorne,Adam";
tbResults = DelimitedStringToTable(string,",");
for i, name in tbResults do
    Dialog.Message("Name",name);
end

]]--
function DelimitedStringToTable(DelimitedString, Delimiter)
	tbReturn = {};
	local strWorking;
	local nPos = nil;
	local strData;
	local nTableIndex = 1;
	local nDelimiterLength = String.Length(Delimiter);
	
	if(nDelimiterLength < 1)then
		tbReturn[nTableIndex] = DelimitedString;
		return tbReturn;
	end
	
	strWorking = DelimitedString;
	nPos = String.Find(strWorking,Delimiter);
	while(nPos ~= -1)do
		strData = String.Left(strWorking,nPos-1);
		tbReturn[nTableIndex] = strData;
		nTableIndex = nTableIndex + 1;
		local nLength = String.Length(strWorking);
		strWorking = String.Right(strWorking,nLength - (nPos + (nDelimiterLength-1)));
		nPos = String.Find(strWorking,Delimiter);
	end
	if(strWorking ~= "")then
		tbReturn[nTableIndex] = strWorking;
	end
	
	return tbReturn;
end

--[[
Function: TableToDelimitedString
Purpose: Makes a table into a delimited string
Arguments: Table - The table to make into a string
           Delimiter - The delimiter
Returns: A delimited string of the table elements
Example:

tbNames = {};
tbNames[1] = "Brett";
tbNames[2] = "Mark";
tbNames[3] = "Darryl";
tbNames[4] = "Lorne";
tbNames[5] = "Adam";

strOutput = TableToDelimitedString(tbNames,",");
Dialog.Message("Result",strOutput);

]]--
function TableToDelimitedString(Table, Delimiter)
	strReturn = "";
	for i, item in Table do
		strReturn = strReturn..item..Delimiter;
	end
	strReturn = String.TrimRight(strReturn,Delimiter);
	return strReturn;
end
