Hi,

Excuse me for my bad english level, i'm french student

I develop a c++ application for move and clic automatically on application's buttons with my cursor who can't support command line, but GUI only.

With windows.h, I tested this:

C#

SetCursorPos(X,Y);
Sleep(500);
Mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
Sleep(500);
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);

This code of my console application work only if is in foreground ( focused )
So if my console application has not focus, my mouse can't move..

Are you solution for resolve this?

Best regards

The mouse belongs the foreground windows, so changes work only there. You can track the mouse with TrackMouseEvent function. For every tracking cycle you must call it again!!!

To get informed when your windows is activated you must handle the WM_ACTIVATE message.

Mouse has nothing to do with focus. Use the function SendInput:
https://msdn.microsoft.com/en-us/library/windows/desktop/ms646310%28v=vs.85%29.aspx[^].

The function is low-level; it works as the raw mouse and keyboad events came from the device driver.
Don't use the functions mouse_event and keybd_event; they have been superseded with SendInput.

This work perfectly! I tested with Microsoft Paint, TeamViewer, Calc.exe, explorer.exe and other..
But, there are a strange problem with some application as CCleaner, ADwcleaner, MalwareBytes, this not work, he don't focus and click.
(There are a hook key on this applications for block my inputs?)

Thank

Sure. And if it did not work in some cases, it means that your implementation was not 100% accurate. You need to reproduce all the sequence of events happening when a human user uses the mouse. It should be pretty easy.

Okay, I see :-)

Keep the idea that I must reproduce a human sequence, for begin, I test this
( I forget the website source :/ )
================================================
INPUT Input={0};
// left down
Input.type = INPUT_MOUSE;
Input.mi.dwFlags = MOUSEEVENTF_LEFTDOWN;
::SendInput(1, &Input, sizeof(INPUT));

/* /!\ I must Sleep some ms?? /!\ */

// left up
::ZeroMemory(&Input, sizeof(INPUT));
Input.type = INPUT_MOUSE;
Input.mi.dwFlags = MOUSEEVENTF_LEFTUP;
::SendInput(1, &Input, sizeof(INPUT));
================================================

The first "Clic" MOUSEEVENTF_LEFTDOWN (0x02) do not give window focus or clic in a button for some applications that I've quoted.

I must reproduce all the sequence of humain events, but with SendInput(), how I can do this?
