WM_NOTIFY() and GUICtrlCreateContextMenu()

[Mingre]

Hello!

How do I enable contextmenu for listview without the need to disable WM_NOTIFY()?

Here's my working code

expandcollapse popup

#include

#include 

Opt('GUIOnEventMode', 1)

Opt('TrayIconDebug',1)
$Debug_LV = False ; Check ClassName being passed to ListView functions, set to True and use a handle to another control to see it work
