List boxes in dialog boxes

In TPW 1.5 I need to know how to put data (ie null strings) into list boxes which are in dialog boxes made in the resource workshop. I have tried setdlgitemtext with no luck, and the addstring command is a mystery. Thanks.

Hi, it's that Rat again.
The long way round is to send the control a message LB_ADDSTRING
with SendDlgItemMessage :-
    SendDlgItemMessage(hDlg,IDD_LISTBOX,LB_ADDSTRING,0,
                   LongInt(Pchar(@CharArray)));
and that for each string (which here is in CharArray). The Message is LB_ADDSTRING, the wParam is zero and the lParam is the address of the string.

The AddString method to which you refer is when you have a TListBox *object*. You can create one of these with New
in a TDialog derivitive :-
    ListBox : PListBox;
    ListBox:=New(PListBox,InitResource(@self,IDD_LISTBOX));

The InitResource constructor takes the TDialog object (here as self) and the ID of the box. You can now call the AddString method :-
    ListBox^.AddString(String);
OK? or do you want further details?
