Re: [Gambas-user] String[] in Sub, what is going wrong
I would guess somewhere in your code there is line, which make fntexc and
fontliste to point same memory address.
IE "fontliste = fntexc" or perhaps setFontNameList is called twice and that
time with fntexc as parameter.
Can you try to isolate the problem into small demonstration project? If
that is not error in the code (mostly that is the case!), it's bug in
Gambas.

Well, thank you. I will answer here to avoid double explanations. Thank
you all for your answers!
You are right, fntexc is declared upstairs in the module where this
function is. The problem is, however, not fntexc but fontliste. The
function is called from another module. Fontliste is declared PUBLIC
there, and when the function is called, fontliste contains the items.
But when fontliste shall be used within the function, it appears to be
empty.
So it is module 1 which has a string array named FontListe:
Public FontListe As New String[]
.
.
.
Public Sub btnOK_Click()
.
.
ini.setFontNameList(FontListe)
.
.
End
And in module 2 ("ini") the contents is to be copied into the string
array which is there:
Private fntexc As New String[]
.
.
.
Public Sub setFontNameList(fontliste As String[])
'Dim i As Integer
fntexc.Clear'When I stop here, fontliste is filled
fntexc.Insert(fontliste) 'When I stop here, fontliste is empty
' For i = 0 To fntliste.count - 1 'Thanks to Christof for the tip,
but it doesn't run with Insert either
' fntexc.Add(fntliste[i])
' Next
End
So my explanation is that I might need another string array which I
declare within the calling Sub in module 1. But I cannot remember I have
ever had a similar issue before. What confuses me most is that I can see
the contents of the array when I enter the function, but it appears
empty when I want to access it there.

Re: [Gambas-user] String[] in Sub, what is going wrong
I ran the code and I was able to populate fntexc with the array, but I didn't see how you declared fntexc so I am unsure what the difference is between our implementations. For testing sake, I merely made fntexc a public variable . If you were to provide more of the code, it would be a lot easier to get a complete picture. How are you declaring fntexc? If it is a locally scoped variable you will need to either pass a reference to the sub or turn the sub into a function to return data to fntexc.
