hook broadcastsystemmessage

Post by zcecil »

HI,
I want to prevent some WM_message from sending to other applications,
and I hooked BroadcastSystemMessage, BroadcastSystemMessageA, BroadcastSystemMessageW
in user32.dll, but it doesn't work at all.

Is there any possible way to do this?

Yep, there are more APIs than that. E.g. SendMessageA/W, PostMessageA/W and SendMessageTimeoutA/W.
