[Dev-C++] ListBox selections

[Nathan S. <str...@ho...>]

I have created a child window with WM_NOTIFY. Is there a way to have a
message sent to my app? LBN_SELCHANGE isn't sent? I don't want to sent it,
just receive some message. I am sure something like this has been posted
somewhere but I haven't found it yet.

  hChildPB=CreateWindow("LISTBOX","",WS_CHILD | WS_CLIPSIBLINGS | LBS_NOTIFY
 | WS_VSCROLL, 10,40,148,180,hwnd,NULL,g_hInst,0);

 above is how I create it.


      case WM_COMMAND:
   switch( wParam )
   {
   case LBN_SELCHANGE:
        MessageBox(hwnd,"it worked","I wish :(",MB_OK);
          break;

 then rest of my WM_COMMAND case which all works.

but the messagebox is never displayed.

Well, this is the problem. According to the Win32 API docs, the
WM_COMMAND has the following parameters:

wNotifyCode = HIWORD(wParam); // notification code
wID = LOWORD(wParam);         // control identifier
hwndCtl = (HWND) lParam;      // handle of control

Just replace wParam by HIWORD(wParam) and everything should work.

>>WM_NOTIFY. ??

This notification message applies only to a list box that has the
LBS_NOTIFY style.

Opps, I do have the LBS_NOTIFY style but I never receive the message. I am
processing it as a part of WM_COMMAND message

any know how?

I have a listbox with LBS_NOTIFY style but my app receives no messages when
a user selects an item in the listbox.

For me, a WM_COMMAND message is sent to the window procedure, with the
LBN_SELCHANGE notification code. So, to get more help, you will have
to post the part of the code where you process the WM_COMMAND message,
and maybe the code which creates the listbox. Somewhere there must be
a bug in your code.

above is how I create it.


     case WM_COMMAND:
  switch( wParam )
  {
  case LBN_SELCHANGE:
       itoa(10,TempText,10);
       MessageBox(hwnd,TempText,TempText,MB_OK);
         break;

then rest of my WM_COMMAND case which all works.
