Beginner's question re: List GUI

4 posts in this topic

If the question has been asked and answered here, I apologize: I couldn't find it anywhere.

A complete beginner's question; I hope it's easy to answer.

Scenario:

1) I have a text file, C:\FILE.TXT.

2) The text file contains three lines:

ONE

TWO

THREE

3) I wish to read the content of the text file into a variable and display each line in a list box to enable the user to choose between "ONE", "TWO", or "THREE" by clicking on the relevant entry in the list box.

I have no trouble reading from the text file. Placing the variable into a message box also provides the list, as in the file, in three lines.

However, the list box, while showing the complete contents of the text file, removes all carriage returns / line feeds. Thus, the list box contains only one item:

ONETWOTHREE

when of course I want the list to display each line of the text file as a distinct item.

I do this sort of thing in Macro Express all the time, where you can easily create a multiple choice window by reading in the contents of a text file; at each CRLF, a new item is added to the array.

I'm sure this is simplicity itself in AutoIt... except not for me.

Thank you for your patience!

Please check function "GUICtrlCreateListView" in the help file. You'll find an example explaining how to use it in a script.

OneManInThisWorld,

Welcome to the Autoit forum. :)

If you add data to a List control, the separate items need to be separated by the "DataSeparatorCharacter", not @CRLF, as explained in the Help file ;)

So you need to replace the @CRLF by that character (| by default in AutoIt):

#include <GUIConstantsEx.au3>

$sText = StringReplace(FileRead("List.txt"), @CRLF, "|")

$hGUI = GUICreate("Test", 500, 500)

$hList = GUICtrlCreateList("", 10, 10, 480, 200)
GUICtrlSetData($hList, $sText)

GUISetState()

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

And now you get your 3 lines - all clear? ;)

water and melba23,

thank you for the friendly welcome; and thank you for the solution to my query. I'm quite proficient with Macro Express, but AutoIt is a slightly different animal, and it will take me a while to hone my instincts.

Your solution worked for me instantly; thanks a lot.

Cheers,
