thank you for reply but I dont want to download external software .

this coded by atoms
I want to use something like that but to send key press to the window can we use sendMessage(hWnd ..

sorry I am still beginner
Code:
local hWndNotepad = findWindow('Notepad');
local hWndChild = getWindow(hWndNotepad, 5); -- Get the child edit control..

sendMessage(hWndChild, 0x0100, 0x48, 0); -- Send WM_KEYDOWN
sendMessage(hWndChild, 0x0101, 0x48, 0); -- Send WM_KEYUP
sendMessage(hWndChild, 0x0102, 0x48, 0); -- Send WM_CHAR


Can I edit this code to send key presses to the game I need something that

Hm, I hadn't expected sendMessage to work based on something I'd found when googling before but that does. Presumably because it uses the child window

Since I'm not sure how atom0s found the number 5 all I can tell you is to test random numbers with your game and see if you can get it to work. While CE does have a "dissect windows" tool accessed from the memory browser for notepad it only shows the main window not the children for notepad so not sure if that'll be any use here...

You can read up on how getWindow works here:
https://msdn.microsoft.com/en-us/library/windows/desktop/ms633515(v=vs.85).aspx

It is just a wrapper around the normal Win32 API 'GetWindow'. The second param 5 means 'GW_CHILD', which means:

Quote:
The retrieved handle identifies the child window at the top of the Z order, if the specified window is a parent window; otherwise, the retrieved handle is NULL. The function examines only child windows of the specified window. It does not examine descendant windows.


In the example you mentioned that I wrote, it was just a hard-coded method to show a basic jist of sending keys to a child control of another window. I wouldn't recommend relying on using '5' all the time in other situations as the Z-order of controls is not guaranteed to be the same on all machines or on all launches of a process.

Instead, you should iterate over the controls and look for the specific one you want via using the GW_HWNDFIRST / GW_HWNDLAST / GW_HWNDNEXT commands.
