python win32api.shellexecute_socket send函数

记事本的主窗口中还有一个窗口，您需要向它发送消息。您可以使用Microsoft Spy++工具查看此“隐藏”窗口，也可以获取所有子窗口，如下所示：def callback(hwnd, hwnds):

if win32gui.IsWindowVisible(hwnd) and win32gui.IsWindowEnabled(hwnd):

hwnds[win32gui.GetClassName(hwnd)] = hwnd

return True

hwnds = {}

win32gui.EnumChildWindows(whndl, callback, hwnds)

我们正在查找的窗口具有“Edit”类名，它是记事本唯一启用且可见的子窗口。所以你的代码是这样工作的：import win32api, win32con, win32gui, win32ui, win32service, os, time

def f_click(pycwnd):

x=300

y=300

lParam = y <<15 | x

pycwnd.SendMessage(win32con.WM_LBUTTONDOWN, win32con.MK_LBUTTON, lParam);

pycwnd.SendMessage(win32con.WM_LBUTTONUP, 0, lParam);

def get_whndl():

whndl = win32gui.FindWindowEx(0, 0, None, ‘NB.txt – Notepad’)

return whndl

def make_pycwnd(hwnd):

PyCWnd = win32ui.CreateWindowFromHandle(hwnd)

return PyCWnd

def send_input_hax(pycwnd, msg):

f_click(pycwnd)

for c in msg:

if c == “\n”:

pycwnd.SendMessage(win32con.WM_KEYDOWN, win32con.VK_RETURN, 0)

pycwnd.SendMessage(win32con.WM_KEYUP, win32con.VK_RETURN, 0)

else:

pycwnd.SendMessage(win32con.WM_CHAR, ord(c), 0)

pycwnd.UpdateWindow()

whndl = get_whndl()

def callback(hwnd, hwnds):

if win32gui.IsWindowVisible(hwnd) and win32gui.IsWindowEnabled(hwnd):

hwnds[win32gui.GetClassName(hwnd)] = hwnd

return True

hwnds = {}

win32gui.EnumChildWindows(whndl, callback, hwnds)

whndl = hwnds[‘Edit’]

pycwnd = make_pycwnd(whndl)

msg = “It works !\n”

send_input_hax(pycwnd,msg)

lParam是int，您在这里看到的技巧是允许您通过一个参数传递多个值。假设我们需要将两个数字传递给只接受一个参数的函数。我们可以将它们作为两位数发送，并在函数中进行拆分。同样，按位移位(&lt；&lt；)和按位或(|)操作在您的情况下也可以反转：>>> x = 300

>>> y = 300

>>> lParam = y << 15 | x

>>> lParam & 0x7FFF # x

0: 300

>>> lParam >> 15 # y

1: 300
