Setting up a hook procedure? - Forums

Home » Forums » MAIN » Setting up a hook procedure?

I have looked at iczelions example and i think i have it right but doesnt seem to work.
What I'm trying to do is to intercept the message WM_QUERYENDSESSION
when it is sent to any app currently running. I'm Using the WH_CALLWNDPROC hookid, with a null value for the thread ID.
eg.



invoke SetWindowsHookEx,WH_CALLWNDPROC,addr CallWndProc,hInstance,NULL 

[\CODE]



but the problem is it doesnt seem to redirect all messages thru my hook procedure. only messages from my window that installs the hook. I am using the same method as the example with a DLL. 

Thanks

    Did you remember to make the datasections shared when you link?

    David,

Yes it is shared....just not sure if this is the best way to check if a machine is attempting a reboot. and then to abort it.
