Sugestion:

Re: List Box Object

From another post:

What you could do in this case is read the text file using a TEXT FILE->READ action which would read the text file into a variable. Just make sure that it is formatted correctly with the proper delimiters.

Then you could use a LISTBOX OBJECT->ADD action and place the variable in the "Items to add" field. This should accomplish what you are looking to do.
Hope that helps.

Re: List Box Object

Ok, it work´s, but in my txt file I have one item per line and the delimiter is a carriage return ( enter ).

Re: List Box Object

Is that meaning it doesnt work properly?

Format for txt file (if yurs doesnt work) is more likely to be:

Item1;;Item2;;Item3 etc etc

Re: List Box Object

I can´t change the TXT file. This file is generated by another program.

Re: List Box Object

Load the file into a variable, then do a search and replace on the text in that variable to replace every carriage return/line feed combination with ;; (or whatever delimiter you intend to use).

You'll need to set up a pair of design-time constants to represent the carriage return and line feed. Something like this:

#ASC_CR# <-- assign "13" to this one
#ASC_LF# <-- assign "10" to this one

(I may have those ASCII values reversed -- I can never remember which one is which -- but you get the idea.)

Then replace every "#ASC_CR##ASC_LF#" with ";;" in the string.

That will convert every newline to a ;;.

Re: List Box Object

Hi,

If you wanted, you could parse the Text file line by line using our Text File actions.

Re: List Box Object

There may be a way to get all of the information to show properly in a ListBox Object.

Try making a script that does something like:

%Count% = "0"
%LineCount% = TextFile.CountLines("c:\....")
WHILE (%Count% < %LineCount%)
. %TextLine% = TextFile.GetLine ("C:\.....",%Count%)
. ListBoxObject[ListBox1].Add (End,"%TextLine%")
. %Count% = Evaluate (%Count% + 1)
END WHILE

I have not actually tested this script but I think that it will work.

Re: List Box Object

Heh, my way only needs 2 actions, and it's faster:

%TextFile% = TextFile.Read("filename")
%NewString% = String.Replace("%TextFile%", "#ASC_CR##ASC_LF#", ";;")

Or just copy and paste this (make sure you change the name of the text file).

Make sure you add the two design-time constants on the Configurations tab of the Project Settings dialog, too:

Name: #ASC_CR#
Value: 13

Name: #ASC_LF#
Value: 10
