呵，要用就直接show_msg(标题,内容)就会出现消息提示，注意编码，还有pywin32模块

还有就是ctypes扩展模块要装上（2.5已经是标准模块了，2.4却还不是）。

适用于2.4的版本：

只要改动这几行：
class PyNOTIFYICONDATA:
     _struct_format = (
         "I" # DWORD cbSize;
         "I" # HWND hWnd;
         "I" # UINT uID;
         "I" # UINT uFlags;
         "I" # UINT uCallbackMessage;
         "I" # HICON hIcon;
         "128s" #    TCHAR szTip[128];
         "I" # DWORD dwState;
         "I" # DWORD dwStateMask;
         "256s" # TCHAR szInfo[256];
         "I" #     union {
             #    UINT  uTimeout;
             #    UINT  uVersion;
             #} DUMMYUNIONNAME;
         "64s" #    TCHAR szInfoTitle[64];
         "I" #  DWORD dwInfoFlags;
         #       GUID guidItem;
     )
     #_struct = struct.Struct(_struct_format)

     hWnd = 0
     uID = 0
     uFlags = 0
     uCallbackMessage = 0
     hIcon = 0
     szTip = ''
     dwState = 0
     dwStateMask = 0
     szInfo = ''
     uTimeoutOrVersion = 0
     szInfoTitle = ''
     dwInfoFlags = 0

     def pack(self):
         return struct.pack(self._struct_format,
             struct.calcsize(self._struct_format),
             self.hWnd,
             self.uID,
             self.uFlags,
             self.uCallbackMessage,
             self.hIcon,
             self.szTip,
             self.dwState,
             self.dwStateMask,
             self.szInfo,
             self.uTimeoutOrVersion,
             self.szInfoTitle,
             self.dwInfoFlags)

     def __setattr__(self, name, value):
         # avoid wrong field names
         if not hasattr(self, name):
             raise NameError, name
         self.__dict__[name] = value

哦，那个是python2.4的问题。2.4的struct模块没有Struct类……
引用 删除 3s4d   /   2009-01-09 08:49:07
加载后 提示struct错误
Traceback (most recent call last):

    class PyNOTIFYICONDATA:

    _struct = struct.Struct(_struct_format)

刚刚接触python,看lz的文章也挺有意思的
上边的代码style. = win32con.WS_OVERLAPPED | win32con.WS_SYSMENU多了一个点。去掉就好用了。很好玩~
