How to log activated windows?

[stax76]

I've a very annoying defect on my system, sometimes there is a window popping up, and I don't know what it is because it can only be seen for a few milliseconds, I don't see much more than the blinking of the title bar of the currently active application. First I thought it was Anki because I use that a lot, but later I also noticed it in Sublime Text and MusicBee.

If I remember correctly, a Win32 hooking API exists for window activation, or I try to record the screen until it happens. I need to find out which crappy process is the culprit, any ideas for a simple solution?

Code: Select all

#SingleInstance Force
Loop {
 WinWaitNotActive, A
 SoundBeep, 1500
 WinGet, proc, ProcessName, A
 ToolTip, % list := proc (list ? "`n" : "") list
}

Thanks for helping. I was not able to fix the issue. Meanwhile, I recorded the screen with OBS, and this showed the title bar changes color a few milliseconds indicating that the application loses focus shortly, but there didn't appear another window on screen or in the taskbar, at least not in the recording.

Did mikeyww’s script indicate any changes in the active window? You haven’t mentioned that you used it.

that script relies on the window actually becoming the foreground window. if it doesnt do that, then nothing gets logged obviously
if that is the case, u can monitor window creation using a WinEventHook

Maybe this will work?

Code: Select all

#SingleInstance Force
Loop {
 oldActive := WinExist("A")	
 WinWaitNotActive, A
 while !(newActive := WinExist("A")) || (newActive = oldActive)
	Sleep 0
 WinGet, proc, ProcessName, A
 ToolTip, % list := proc (list ? "`n" : "") list
}
