Very intermediate into programming and never done anything with visual
basic, although if anyone could help me better understand the
following I would be very greatful!
In my ruby script I have
user32 = DL.dlopen('user32')
actWindow = DL::CFunc.new(user32['GetActiveWindow'],DL::TYPE_VOID,
which has wrong number of arguments, needs an array passed into it.
actWindow.call() returns type nil
I'm not sure what I should be passing into call method as the function
is of DL::TYPE_VOID?
