Yes it is, but you can use Spy++ to retrieve it's value. With Spy++ Scan
messages sent to the Window which has created TrayIcon ( "Title
TrayIconWindow" in my sample application), then move your mouse on the
TrayIcon for which you want to retrieve the ID, then you'will see in the
scan Messages window of Spy++ a message like
"WM_COMMAND wNotifyCode:0000 wID:130 hwndCtl:00000200"
wID is the value of the TrayIcon (130 in my sample).
