Refill ListBox appends to the list

[kdaube]

Dear all,
I want to change the contents of the listbox (in this test by button):

Code: Select all

global wordList := "word-1|word-2"

Gui, Add, ListBox,  x005 y005 w170 h120 multi   vWords,     %wordlist%
Gui, Add, Button,   x200 y005 w120 h020         gChange,    Change content 
Gui, Show,          x800 y300 h150 w350
Return

Change:
  Gui, Submit, noHide 
  wordList := "word-3|word-4"
  GuiControl,, Words, %wordList%
Return

GuiClose:   
ExitApp

But the contents of the box is enlarged with each action of the butt - rather than filled with new content.
Whre is my error?

Thank You for any help

Just start the new list with a | so wordList := "|word-3|word-4"

Hello Guest: Thank You very much - but how could I know?

Tab/DropDownList/ComboBox/ListBox: Param3 should contain a pipe-delimited list of entries to be appended at the end of the control's list. To replace (overwrite) the list instead, include a pipe as the first character (e.g. |Red|Green|Blue).
