用python怎么查看syslistview32的内容如题用c++的话，SendMessage(hwnd, LVM_GETITEMTEXT, i, (LPARAM)plvi

用python怎么查看syslistview32的内容
如题
用c++的话，SendMessage(hwnd, LVM_GETITEMTEXT, i, (LPARAM)plvitem)可以获得，但是(LPARAM)plvitem这个在python里面怎么获取？
谢谢~

参考一下Notepad的

# encoding: cp936
import win32gui,win32api,win32con

def MsgBox(text, title="Python"):
    win32api.MessageBox(0, text, title, 0)

def ShellExecute(file="", option="", dir=""):
    win32api.ShellExecute(0, "open", file, option, dir, win32con.SW_SHOWNORMAL)

def SetForegroundWindow(whnd):
    win32gui.SetForegroundWindow(whnd)

def FindWindow(classname=None, title=None):
    whnd = win32gui.FindWindow(classname, None)
    return whnd

def FindWindowEx(handle=None, classname=None):
    ehnd = win32gui.FindWindowEx(handle,0,classname,None)
    return ehnd

def SetText(ehnd, text):
    win32gui.SendMessage(ehnd, win32con.WM_SETTEXT, 0, text)

def SetSelText(ehnd, text):
    win32gui.SendMessage(ehnd, win32con.EM_REPLACESEL, 0, text)

def GetText(ehnd):
    buf_size = 1 + win32gui.SendMessage(ehnd, win32con.WM_GETTEXTLENGTH, 0, 0)
    buffer = win32gui.PyMakeBuffer(buf_size)
    win32gui.SendMessage(ehnd, win32con.WM_GETTEXT, buf_size, buffer)
    return buffer[:buf_size]

if __name__=='__main__':
    whnd = FindWindow("Notepad", None)
    ehnd = FindWindowEx(whnd, "Edit")
    print whnd,ehnd
    SetForegroundWindow(whnd)
    SetText(ehnd, "xyz")
    print GetText(ehnd)

能查看notepad的，但是syslistview32控件中的内容看不到

自己顶一下；
我看了一下c++的，plvitem好像要从进程里面分配一块内存区域，然后把数据读入到这个区域里面，我通过ctypes.windll.kernel32.VirtualAllocEx(hProcess,0,4096,win32con.MEM_COMMIT,win32con.PAGE_READWRITE)创建了一个内存区域，但是还是得不到syslistview32里面的内容

from win32con import PAGE_READWRITE, MEM_COMMIT, MEM_RESERVE, MEM_RELEASE,\
PROCESS_ALL_ACCESS
from commctrl import LVM_GETITEMTEXT, LVM_GETITEMCOUNT

import struct
import ctypes
import win32api
import win32gui

GetWindowThreadProcessId = ctypes.windll.user32.GetWindowThreadProcessId
VirtualAllocEx = ctypes.windll.kernel32.VirtualAllocEx
VirtualFreeEx = ctypes.windll.kernel32.VirtualFreeEx
OpenProcess = ctypes.windll.kernel32.OpenProcess
WriteProcessMemory = ctypes.windll.kernel32.WriteProcessMemory

ReadProcessMemory = ctypes.windll.kernel32.ReadProcessMemory
memcpy = ctypes.cdll.msvcrt.memcpy

def readListViewItems(hwnd, column_index=0):

    # Allocate virtual memory inside target process
    pid = ctypes.create_string_buffer(4)
    p_pid = ctypes.addressof(pid)
    GetWindowThreadProcessId(hwnd, p_pid) # process owning the given hwnd
    hProcHnd = OpenProcess(PROCESS_ALL_ACCESS, False, struct.unpack("i",pid)[0])
    pLVI = VirtualAllocEx(hProcHnd, 0, 4096, MEM_RESERVE
