In Autohotkey Format the output of a ListBox? - autohotkey

Question

In Autohotkey, I have the following code :
^r::
Gui, Add, ListBox, Multi vMyListBox r10, Strawberries|Pears|Oranges|`r|Beans|Peas|Tomatoes|Turnips|
Gui, Add, Button, Default, OK
Gui, Show
return
ButtonOK:
Gui, Submit
MsgBox % MyListBox
send, % MyListBox
return
The output is, e.g. :
Strawberries|Beans|Turnips
But I would like it to be :
Strawberries, Beans, Turnips,
How should I proceed ?
Thanks in advance

Sounds like a job for RegEx.
Using RegExReplace() with the MyListBox variable as the haystack and "\|" as the needle. See this interactive for an explanation of this particular RegEx needle.
Saving the replaced version of the String in a variable called NewStr gives us this line of code:
NewStr := RegExReplace(MyListBox, "\|" , Replacement := ", ")
Current Code:
^r::
Gui, Add, ListBox, Multi vMyListBox r10, Strawberries|Pears|Oranges|`r|Beans|Peas|Tomatoes|Turnips|
Gui, Add, Button, Default, OK
Gui, Show
return
ButtonOK:
Gui, Submit
MsgBox % MyListBox
NewStr := RegExReplace(MyListBox, "\|" , Replacement := ", ")
MsgBox % NewStr
send, % NewStr
return
However, this version does not add a trailing ", ". In order to add this, let's just append a ", " to the NewStr variable we just created with NewStr.=", "
Final Code:
^r::
Gui, Add, ListBox, Multi vMyListBox r10, Strawberries|Pears|Oranges|`r|Beans|Peas|Tomatoes|Turnips|
Gui, Add, Button, Default, OK
Gui, Show
return
ButtonOK:
Gui, Submit
MsgBox % MyListBox
NewStr := RegExReplace(MyListBox, "\|" , Replacement := ", ")
NewStr.=", "
MsgBox % NewStr
send, % NewStr
return
