我目前有第三方ActiveX控件，旨在用于VB6。我想将控件迁移到python。我得到了win32com，然后我跑了'makepy.py -i＆＃39;在类型库文件上。我了解如何使用win32com.client.Dispatch（）方法调度可执行容器，然后调用子类。容器被称为Sterling，并且在调用对象时将运行，但我不会在VB代码中专门提到容器，所以我认为这里也不需要它。我从那些COMM对象获得的只是类型库，但是，它似乎都适用于VB6。这是我添加对Sterling.tlb类型库的引用后工作和访问COM对象的VB6代码：
' Declare ActiveX type library class
Public WithEvents m_STIQuote As STIQuote
Private Sub Form_Load()
......................................
' Create an instance of type library class
Set m_STIQuote = New STIQuote
......................................
End Sub
Private Sub Form_Unload(Cancel As Integer)
......................................
' destroy type library class
Set m_STIQuote = Nothing
......................................
End Sub
Private Sub btnMDX_Click()
' structSTIMdxRegEx is a structure that comes with ActiveX type library
Dim inMDXInfo As structSTIMdxRegEx
inMDXInfo.bstrExchanges = "N"
inMDXInfo.bstrMsgTypes = ""
inMDXInfo.bReg = True
inMDXInfo.bAllSyms = True
inMDXInfo.bNewOnly = False
'Call method in ActiveX class with the structure provided as an input
m_STIQuote.RegisterMdxEx inMDXInfo
End Sub
' Event handler provided by the library that receives class with data as an argument.
Private Sub m_STIQuote_OnSTIQuoteUpdate(structQuoteUpdate As SterlingLib.structSTIQuoteUpdate)
LogMsg "MDX|" & structQuoteUpdate.bstrSymbol & "|" & structQuoteUpdate.nMdxMsgType
End Sub
这是我到目前为止在python中所拥有的，它无法从Record map中找到_ISTIQuoteEvents类和结构：
import win32com.client
from win32com.client import gencache
gencache.EnsureModule('{C418ADDA-61CC-4854-B69E-87F8BF6D7A0E}', 0, 1, 0)
class myQuoteEvents(_ISTIQuoteEvents):
def OnSTIQuoteUpdate(self, structQuoteUpdate=defaultNamedNotOptArg):
print_str = "MDX|" + structQuoteUpdate.bstrSymbol + "|" + structQuoteUpdate.nMdxMsgType
print print_str
myQuote = win32com.client.DispatchWithEvents("STIQuote.STIQuote_ctrl.1", myQuoteEvents)
inMDXInfo = structSTIMdxRegEx()
inMDXInfo.bstrExchanges = "N"
inMDXInfo.bstrMsgTypes = ""
inMDXInfo.bReg = True
inMDXInfo.bAllSyms = True
inMDXInfo.bNewOnly = False
myQuote.RegisterMdxEx(inMDXInfo)
_ISTIQuoteEvents 是makepy生成包装器中的一个类，但由于某些原因，它在脚本中不可见。我打电话给gencache，所以我觉得我应该可以看到它，但这个名字不被识别。 ISTIQuote 是一个派生自DispatchBaseClass的类，是一个接口类。 STIQuote 是包装器中的CoClassBaseClass派生类，它包含ISTIQuote作为接口＆amp; _ISTIQuoteEvents作为事件。容器应用程序是在计算机上运行的第三方程序，因此此代码仅在容器运行时执行。在COMM术语中它的英镑。应该是英镑。所以STIQuote是Sterling的子类。 structQuoteUpdate 和 structSTIMdxRegEx 都只有带有CLSID的RecordMap条目，但我知道它们包含在VB6环境中的字段。我想知道如何从包装器中提取它们以访问它们的数据结构。
这是python包装器，只有makepy.py中的相关信息：
