發送一些密鑰到非活動窗口與python

Question

我試着發送一些密鑰到非活動窗口/進程/程序（win32/64）使用python。已經閱讀了pywinauto和SendKeys，但是它們都在發送密鑰之前激活了窗口。

有沒有任何方式使用不活動窗口而不激活它？

如果有人發佈簡單的示例/代碼片段，那將會很棒。

謝謝。

Answer 1

嘗試使用的SendKeys庫之一：

Answer 2

這是一個很老的文章，但還沒有在這裏的答案，我一直在尋找這樣的東西，而我花了6個小時才通過Stackoverflow，最後只讀了所有的C文檔，因爲它更有用。

<python> 
#you will need the win32 libraries for this snippet of code to work, Links below 
import win32gui 
import win32con 
import win32api 
from time import sleep 

#[hwnd] No matter what people tell you, this is the handle meaning unique ID, 
#["Notepad"] This is the application main/parent name, an easy way to check for examples is in Task Manager 
#["test - Notepad"] This is the application sub/child name, an easy way to check for examples is in Task Manager clicking dropdown arrow 
#hwndMain = win32gui.FindWindow("Notepad", "test - Notepad") this returns the main/parent Unique ID 
hwndMain = win32gui.FindWindow("Notepad", "test - Notepad") 

#["hwndMain"] this is the main/parent Unique ID used to get the sub/child Unique ID 
#[win32con.GW_CHILD] I havent tested it full, but this DOES get a sub/child Unique ID, if there are multiple you'd have too loop through it, or look for other documention, or i may edit this at some point ;) 
#hwndChild = win32gui.GetWindow(hwndMain, win32con.GW_CHILD) this returns the sub/child Unique ID 
hwndChild = win32gui.GetWindow(hwndMain, win32con.GW_CHILD) 

#print(hwndMain) #you can use this to see main/parent Unique ID 
#print(hwndChild) #you can use this to see sub/child Unique ID 

#While(True) Will always run and continue to run indefinitely 
while(True): 
    #[hwndChild] this is the Unique ID of the sub/child application/proccess 
    #[win32con.WM_CHAR] This sets what PostMessage Expects for input theres KeyDown and KeyUp as well 
    #[0x44] hex code for D 
    #[0]No clue, good luck! 
    #temp = win32api.PostMessage(hwndChild, win32con.WM_CHAR, 0x44, 0) returns key sent 
    temp = win32api.PostMessage(hwndChild, win32con.WM_CHAR, 0x44, 0) 

    #print(temp) prints the returned value of temp, into the console 
    print(temp) 
    #sleep(1) this waits 1 second before looping through again 
    sleep(1) 
</python> 

我見過的帖子遍佈使用

hwndEdit = win32gui.FindWindowEx(hwndMain, hwndChild, "Edit", "test - Notepad"); 

，但我永遠無法弄清楚。除此之外，微軟網站上的所有文檔都有不同的含義，因此我添加了自己的理解。

這應該讓你開始，應該對別人有幫助。如果其他人有修改讓我知道。
