Hopefully it's just something silly I'm doing causing this crash.. Using this code if I click on a header a few times (the number of times seems random) it bombs the entire application. OnError isn't much help as from what I understand it can report some crazy stuff with code in callbacks (and does, in this case!).

Hopefully someone can give me a hand! Thanks!

Code: Select all

  If Message = #WM_NOTIFY        ; these events are send as notification messages
    
    *pnmh.NMHDR = lParam  ; lParam points to a structure with more info
    
    Select *pnmh\hwndFrom
    
      ;
      ; See if it is the right gadget
      ;
      Case GadgetID(#Gadget_main_lst_c_search_results) 
        
        ;
        ; This code contains actual message
        ;
        Select *pnmh\code  
          
          ;
          ; User clicked on the Header of a column
          ;
          Case #LVN_COLUMNCLICK 
            
            *pnmv.NMLISTVIEW = lParam ; another info structure
            
            Column.l = *pnmv\iSubItem ; clicked column
            
            ;
            ; Column starts at 0
            ;
            header_text.s = GetColumnHeaderText(#Gadget_main_lst_c_search_results, Column)
            
            If Right(header_text,1) = "<"

              order_dir.s = "ASC"
              
              order_char.s = ">"

              order_char.s = "<"

Hi Karbon,

may be a bug in my Lib MoreListIconGadget. I have to take a closer look.

Please, send-me all your code by e-mail (Denislabarre@Free.fr) and wich OS you are using to.

Tks

Denis
