Hi all

See this from the API definition:

LBN_DBLCLK

idListBox = (int) LOWORD(wParam);  // identifier of list box
hwndListBox = (HWND) lParam;      // handle of list box

I want to check whether a list box entry has been double clicked, but I don't understand how to implement this.  I know how to check the low word for the correct value, but where do I specify the idListBox?

At the moment I am checking (under WM_COMMAND) whether the listbox id is stored in eax, then checking the low word for LBN_DBLCLK.

Am I going about it the correct way, or do I have it all wrong?

ps In fact I have noticed that LBN_DBLCLK is not defined in any of the include files, so how can it be checked?

LBN_DBLCLK      equ 2

In Windows.inc - well, in mine at least :-/

.IF uMsg == WM_COMMAND
mov eax, wParam
movzx edx, ax ; edx has LOWORD == ID of ListBox
shr eax, 16 ; eax has now a notification value.
   .IF edx == IDListBox && eax == LBN_DBLCLK
           ;someone doubleclicked
   .ENDIF
.ENDIF

;untested code - should work. Good luck.
