Hooking Troubles

[Brent113]

I am using a JournalRecord hook to monitor the keyboard and mouse, and a GetMessage hook to monitor if that hook gets removed with ctrl-esc or ctrl-alt-del so I can reinstall it. Everything works great except:

Small problem: hit the volume key on the keyboard and the entire system freezes, and you have to use some clever ctrl-alt-deleting to close the program. The mouse and keyboard are unresponsive until you "refresh" with a ctrl-alt-del or ctrl-esc.

Any ideas as to what might cause this or how I can prevent this from happening?

Difficult to say without seeing some of you code.

BTW, I'm not sure why you need the GetMessage hook

 

[Brent113]

You do need the getmessage hook or there is no way of detecting if the journal gets removed. If you'd like me to paste the code, I can, but it's nothing special, just standard hook code

I've actually used this same code in other programs just fine. The procedure it's in is kind of long, I wonder if that could have anything to do with it. But why only the volume keys?

Fair enough, although I think I'd probably try subclassing the top-level window rather than putting in another hook. But I guess that's just splitting hairs.

I guess for the record I'll state the workaround I used, and it works, becuase it uses equivalent functions.

Instead of using the JournalRecord hook with a GetMessage, I used a Keyboard and a Mouse hook separately. I had to change the code a smidge, but now it doesn't kill windows
