[zmud 4.62] DDE 问题

nyrang

我有一个python的DDE test server

import win32ui
from pywin.mfc import object
import dde
class MySystemTopic(object.Object):
def __init__(self):
  object.Object.__init__(self, dde.CreateServerSystemTopic())
def Exec(self, cmd):
  print "System Topic asked to exec", cmd
class MyOtherTopic(object.Object):
def __init__(self, topicName):
  object.Object.__init__(self, dde.CreateTopic(topicName))
def Exec(self, cmd):
  print "Other Topic asked to exec", cmd
class MyRequestTopic(object.Object):
def __init__(self, topicName):
  topic = dde.CreateTopic(topicName)
  topic.AddItem(dde.CreateStringItem(""))
  object.Object.__init__(self, topic)
def Request(self, aString):
  print "Request Topic asked to compute length of:", aString
  return(str(len(aString)))
server = dde.CreateServer()
server.AddTopic(MySystemTopic())
server.AddTopic(MyOtherTopic("RunAnyCommand"))
server.AddTopic(MyRequestTopic("ComputeStringLength"))
server.Create('RunAny')
while 1:
win32ui.PumpWaitingMessages(0, -1)


在zmud 4.62 里面执行#DDE RunAny RunAnyCommand hihihi ，能够看到python里面print出来"Other Topic asked to exec hihihi".

用函数%dde, %ddeopen, %ddepoke，在mud里面都只显示“什么？”。显然是函数无法调用。

谁能告诉一下到底应该怎么用dde函数从一个dde server里面获取值?

#dde相当于subroutine，%dde是函数所以要返回字符串值，你直接在命令行里执行%dde，返回的字符串就回送到mud，是没有意义的指令，所以有“什么”，你试试看#say %dde(..)

谢谢，#show #say 我昨天都试过了，今天发现问题在于调用错了，%dde是要返回值的，调用上面的RunAnyCommand是不行的，换成#say %dde(RunAny,ComputeStringLength,hihdfljaljfdlafd)就work了，thanks!
