DoubleClick (ListBox)
Hello there!
Whenever a user DoubleClicks an entry in a ListBox I am trying to call a function.
Searching the documentation and this forum did not help me: found nothing concerning DoubleClicks ...
I tried intercepting LBN_DBLCLK (--> http://msdn.microsoft.com/en-us/library/ms997541.aspx) with NSD_OnNotify but it never fires ...
(NSD_OnClick is not working for me either ...)
At the moment I am using NSD_OnChange to simulate a very slow and bad 'Double'Click.
Is there any way to call a function if someone doubleclicks an entry in a ListBox?
(... Am I doing something stupid?)
