之前接了个单，需求是对一个炒股软件使用pywin32库自动化输入股票代码，速度要快，考虑到是软件自动化便答应了下来，开始遇到的难度是如何运行代码后自动切换到对应的软件窗口，对于多窗口，如何指定窗口输入指令，尝试了很多方法后都没有实现，后面通过获取子窗口句柄，然后将该句柄置顶并最大化即可实现，具体代码如下

import win32api
import win32con
import win32gui
import win32com.client
import re
import time


def huiche():  # 回车操作
    win32api.keybd_event(13, 0, 0, 0)  # enter键位码

    win32api.keybd_event(13, 0, win32con.KEYEVENTF_KEYUP, 0)  # 释放按键
def anjian(num):
    win32api.keybd_event(num, 0, 0, 0)  #

    win32api.keybd_event(num, 0, win32con.KEYEVENTF_KEYUP, 0)  # 释放按键

class cWindow:
    def __init__(self):
        self._hwnd = None
        self.shell = win32com.client.Dispatch("WScript.Shell")

    def BringToTop(self):
        win32gui.BringWindowToTop(self._hwnd)

    def SetAsForegroundWindow(self):
        self.shell.SendKeys('%')
        win32gui.SetForegroundWindow(self._hwnd)

    def Maximize(self):
        win32gui.ShowWindow(self._hwnd, win32con.SW_MAXIMIZE)

    def setActWin(self):
        win32gui.SetActiveWindow(self._hwnd)

    def _window_enum_callback(self, hwnd, wildcard):
        '''Pass to win32gui.EnumWindows() to check all the opened windows'''
        if re.match(wildcard, str(win32gui.GetWindowText(hwnd))) is not None:
            self._hwnd = hwnd

    def find_window_wildcard(self, wildcard):
        self._hwnd = None
        win32gui.EnumWindows(self._window_enum_callback, wildcard)

    def kill_task_manager(self):
        wildcard = 'Gestionnaire des t.+ches de Windows'
        self.find_window_wildcard(wildcard)
        if self._hwnd:
            win32gui.PostMessage(self._hwnd, win32con.WM_CLOSE, 0, 0)
if __name__ == '__main__':
    jianma_zd = {}
    for i,j in zip(range(0,10),range(96,106)):
        jianma_zd[str(i)] = j
    print(jianma_zd)
    code = input('输入代码:')
    first_num = code[0]
    last_num = code[1:]
    wildcard = ".*通达信金融终端.*"

    cW = cWindow()
    cW.kill_task_manager()
    cW.find_window_wildcard(wildcard)
    cW.BringToTop()
    cW.Maximize()
    cW.SetAsForegroundWindow()
    time.sleep(0.5)
    print(first_num)
    anjian(jianma_zd.get(first_num))
    time.sleep(0.3)
    for num in last_num:
        anjian(jianma_zd.get(num))
        time.sleep(0.1)
    huiche()

如果上述代码帮助您很多，可以打赏下以减少服务器的开支吗，万分感谢！
