試圖用紅寶石顯示一個氣球通知

Question

我想在ruby中做一個小班，允許我製作一個系統托盤圖標並使用通知氣球。但我在使用Win32API調用結構時遇到問題。

http://www.ruby-forum.com/topic/18102
Shell_NotifyIcon Function
NOTIFYICONDATA Struct

繼承人現在我的代碼，它是所有的圖標添加到系統托盤：

require 'Win32API' 

NIF_MESSAGE = 1 
NIF_ICON = 2 
NIF_TIP  = 4 
NIF_STATE = 8 
NIF_INFO = 10 

NIM_ADD  = 0 
NIM_MODIFY = 1 
NIM_DELETE = 2 

NIS_HIDDEN  = 1 
NIS_SHAREDICON = 2 

class NotifyIconData < Struct.new(:cbsize, :hwnd, :uid, :uflags, :ucallbackmessage, :hicon)#, :sztip, :dwstate, :dwstatemask, :szinfo, :utimeout, :uversion, :szinfotitle, :dwinfoflags, :guiditem, :hballoonicon) 
    def pack 
     values.pack('LLIIIL') 
    end 
    # def self.unpack(s) 
     # new(*s.unpack('LLIIIL')) 
    # end 
end 

#===--- 

ExtractIcon  = Win32API.new('shell32', 'ExtractIcon',  'LPI', 'L') 
Shell_NotifyIcon = Win32API.new('shell32', 'Shell_NotifyIconA', 'LP', 'I') 

hicoY = ExtractIcon.call(0, 'C:\WINDOWS\SYSTEM32\INETCPL.CPL', 21) # Green tick 
hicoN = ExtractIcon.call(0, 'C:\WINDOWS\SYSTEM32\INETCPL.CPL', 22) # Red minus 

#===--- 

tiptxt = "hai" 

nid = NotifyIconData.new 
nid.cbsize   = Marshal.dump(NotifyIconData).size#6*4+64 
nid.hwnd    = 0 
nid.uid    = 'ruby'.hash 
nid.uflags   = NIF_INFO 
nid.ucallbackmessage = 0 
nid.hicon    = hicoY 

ret = Shell_NotifyIcon.call(NIM_ADD, nid.pack << tiptxt << "\0"*(64 - tiptxt.size)) 
p 'Err: NIM_ADD' if ret == 0 

     sleep(3) # <----<< 

# pnid = [6*4+64, 0, 'ruby'.hash, NIF_ICON | NIF_TIP, 0, hicoN].pack('LLIIIL') << tiptxt << "\0"*(64 - tiptxt.size) 
# ret = Shell_NotifyIcon.call(NIM_MODIFY, pnid) 
# p 'Err: NIM_MODIFY' if ret == 0 

     # sleep(6) # <----<< 
nid.uflags = 0 

ret = Shell_NotifyIcon.call(NIM_DELETE, nid.pack << "\0") 
p 'Err: NIM_DELETE' if ret == 0

退房visualuruby和演示/示例文件。他們很容易地給了我一些氣球。
