Alt-F4 | Alternative Factorio Friday Fan Facts, also known as Alt-F4 | Bot library

I have a pyqt5 project. I am starting the window in full screen mode. It is working but because it full screen so I cannot click on x button to close it so I have to press alt-f4 to close it. It works fine but now I have another class running in the project due to which when I press alt-f4, it closes the window but still looks the thread didnt closed due to which it stays in the terminal. Below is the code:

Source code

My App (Windows 7, Visual C++, Release-Build) needs to write some data when windows is shutting down (restarting, user logs off). After all I want to do the same stuff as on receiving WM_CLOSE-Message which gets called during a regular close of my App (Alt-f4, Closing the window,...)

I don't need any User-Input, Dialogs and so on. Just silent writing. The writing itself should last less than a second.

To do so I do the following:

I'm trying my hand at Pynput, and I'm starting off with creating a simple program to record the movements of a mouse, and then replay those movements once a button is clicked.

However, every time I click the mouse, it just starts to freak out and endlessly loop. I think it's going through the movements at a super high speed, but I eventually have to Alt-F4 the shell to stop it.

Any help would be appreciated.

Situation:

I am unable to return focus to the Excel application after initiating a file download.

My usual tricks of AppActivate and Application.hwnd , when working between applications, don't seem to be working this time. I haven't had a problem doing this before so don't know if I am being particularly dense today, or, it is because I am involving a browser for the first time. I suspect it is the former.

Questions:

1) Can any one see where I am going wrong (why focus does not shift back to Excel)?

2) More importantly: Is there a way to download files in the background, using the default browser, keeping the focus on ThisWorkbook and thereby avoiding the issue altogether?

I am using a workaround of SendKeys "%{F4}" immediately after the download, at present, to close the browser and so am defaulting back to Excel.

Note: The default browser in my case is Google Chrome but clearly could be any browser.

What I have tried:

1) From @user1452705; focus didn't shift:

I created a form to handle login to my app, and I'm trying to make the application exit if the login form is closed without logging in (for example, Alt-F4-ing). To do this I call Close() on the main form when DialogResult.OK is not returned but get an exception thrown in Main by Application.Run.

This is for a project I'm working on. Have tried searching for answers and found some saying to call Application.Exit() in the main form but that just makes my form reappear.

The main form's constructor:

I spent a long time reading through past posts and didn't find quite what I need.

I'm making a kiosk-type window using tkinter. I set it to open fullscreen. I want to override the standard alt-f4 command to close it. I don't want it completely uncloseable though. I'd like to instead make up my own keyboard shortcut (alt-ctrl-g-3 or something like that).

I tried some of the suggestions for overriding alt-f4 and couldn't get them to work. In my init function I included:

I have made a custom MessageBox under my main Form.

And have set "Aight" button click listener as:

I have a utility that has a function called by Alt-F4 but I can't because it closes the window. How can I trap Alt-F4 in QB64?
