Code
`My first attempt at an SEH overwrite exploit. Anyhow, I first   
posted about this issue regarding version 7 of this control, Will   
Dormann of the CERT/CC discovered versions 6 and 6.5 are vulnerable   
too, see http://www.kb.cert.org/vuls/id/963889. Dwa7w.dll and   
inotes6w.dll are unicode, thats my next project. Code is inline and   
attached.
