将击键发送到非活动 window

Question

你好，我正在尝试制作一个发送按键 2 的应用程序 chrome 我的当前代码是：

#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)

但我的问题是我如何找到 chrome seing，因为它将名称更改为活动选项卡并且使用它也不起作用： hwndMain = win32gui.FindWindow("Google Chrome", None)

Answer 1

在类似的帖子中，我看到这对人们有用。并且您的代码通过更改标题名称对我有用，但您需要将标题输入顺序修改为这种格式。

 hwndMain = win32gui.FindWindow( "Google Chrome" , None)

TO

 hwndMain = win32gui.FindWindow( None , "Google Chrome")
