Windows XP SP2 may break certain apps

Hmm... makes ya wonder. :) Jeremy Falcon

Anybody heard about this[^]? Anyone have any apps that this may affect? The short summary is that it would appear to mostly affect code that uses DCOM, RPCs, certain kind of memory access (they mention that .Net runtimes had to be adjusted/revamped due to this), Windows FireWall. ¡El diablo está en mis pantalones! ¡Mire, mire!

This may be of some help Training on sp2[^]

Whats wrong in that ? many non ATL applications do the same thing i suppose.

You quoted the wrong part of my post. Michael Dunn wrote: a bit of code, constructed at runtime It's code put in memory that's allocated at runtime, and then executed... exactly what a buffer overrun attack does. --Mike-- Personal stuff:: Ericahist | Homepage Shareware stuff:: 1ClickPicGrabber | RightClick-Encrypt CP stuff:: CP SearchBar v2.0.2 | C++ Forum FAQ ---- Laugh it up, fuzzball.

FWIW, the article says Visual Studio products will be updated to address the compatibility issues. Of course, it remains to be seen if VS6 is still supported.

Whatever happened to the illusive SP6 for VS6. Regards, Kannan
