Sometimes Crash with 0xC0000005 #57

Closed ZhuangQu closed 1 year ago

ZhuangQu commented 1 year ago

My system is Windows 11. I wrote an AutoHotkey script which executes GetDesktopCount, GetCurrentDesktopNumber and GetDesktopName for 16 consecutive times every 100 ms. After running for about 1 hour, AutoHotkey crashes with 0xC0000005 and then loses response.

Why are you calling it every 100ms for an hour? There is event listener which triggers when you change desktop.

I've even gotten explorer.exe to crash if I call some of the functions too many times, something goes wrong somewhere.

ZhuangQu commented 1 year ago

I call the DLL so frequently to know whether the desktop has changed. The listener will crash when I add a desktop in taskview, so I dare not use it.

ZhuangQu commented 1 year ago

I add

ProcessSetPriority("Realtime")

to my AutoHotkey script and it doesn't crash anymore. I don't know why so.

Ciantic commented 1 year ago

Do you add and remove a lot of desktops every day?

Listener is a way to go here, but I do need to find the crash and fix it.

I have 16 desktops at all times, I don't add and remove these practically ever so it's a rare occasion for me.

Yes! And I found that raising the process priority can solve the problem, so I close it.
