获取windows程序界面信息的方法

1. 工具：spy++（vs） 模块：win32-api(c++/c#) pywin32(python)
2. 使用SPY.exe/SPY++.exe定位到Window程序界面窗口（重要的是类CLASS和窗口的标题CAPTION信息）

eg : 获取计算器窗口信息

import win32file, win32api, win32con,win32gui
import os,sys

def find_idxSubHandle(pHandle, winClass, index=0):
    """
    已知子窗口的窗体类名
    寻找第index号个同类型的兄弟窗口
    """
    assert type(index) == int and index >= 0
    handle = win32gui.FindWindowEx(pHandle, 0, winClass, None)
    while index > 0:
        handle = win32gui.FindWindowEx(pHandle, handle, winClass, None)
        index -= 1
    return handle
  
def find_subHandle(pHandle, winClassList):
    """
    递归寻找子窗口的句柄
    pHandle是祖父窗口的句柄
    winClassList是各个子窗口的class列表，父辈的list-index小于子辈
    """
    assert type(winClassList) == list
    if len(winClassList) == 1:
        return find_idxSubHandle(pHandle, winClassList[0][0], winClassList[0][1])
    else:
        pHandle = find_idxSubHandle(pHandle, winClassList[0][0], winClassList[0][1])
        return find_subHandle(pHandle, winClassList[1:])

def getdata(handle):
    return win32gui.GetWindowText(handle)

def demo():
    parenthandle = win32gui.FindWindow("CalcFrame", "计算器")
    data=[]
    for i in range(4):
        handle = find_subHandle(parenthandle, [("CalcFrame", 0), ("#32770", 0), ("Static", i)])
        #print("%x" % (handle))
        data.append(getdata(handle))
        #print(i,getdata(handle))
    #print('计算器数据:',data)
    #input()
    #os.system('pause')
    return data

if __name__=='__main__':
    while True:
        demo()
