Ruby win32 api interface

Answer 1

SHAppBarMessage takes two parameters: a DWORD and a pointer to APPBARDATA,
so it shuold be declared thus:

app_bar_msg = Win32API.new('shell32', 'SHAppBarMessage', ['L', 'P'], 'L')

then called:

msg_id = 1
app_bar_data = "properly initalized binary string" #should have sizeof(APPBARDATA) bytes
app_bar_msg.call(msg_id, app_bar_data)

But I don't know Ruby, so maybe I am mistaken...
