import wx
from md5 import md5
from binascii import b2a_hex
from Debug import error

class Tool(object):
    __slots__ = ['checker', 'key', 'file']

        self.key = b2a_hex(md5(key).digest())
        self.file = os.path.join(wx.GetHomeDir(), self.key)

    def IsAnotherRunning(self):

    def recvdata(self):

        checker =  wx.SingleInstanceChecker(self.key)
        while checker.IsAnotherRunning():

        file.write(data)

tool = Tool()
