When the Windows API help talks about null-terminated strings, they really
mean consecutive characters in memory, with a #0 on the end. Keeping that
in mind, a PChar *is* a long pointer to a null-terminated string. So they
just want a PChar.
But on reflection, you don't really need to copy the string. Passing it
into a function as a const parameter will ensure safety. So use this:
uses Consts;
procedure AddStringToCombo(AHandle: HWnd; const AString: string; AIndex:
Integer);
begin
if SendMessage(AHandle, CB_INSERTSTRING, AIndex,
Longint(PChar(AString))) < 0 then
raise EOutOfResources.Create(SInsertLineError);
end;
and
AddStringToComboBox(GetDlgItem(hdlg, DLG_HELPSIZE), p, 0);
And if that doesn't work it's because GetDlgItem didn't.
Cheers,
Carl
