Why don't you just change the page protection and make the code continue.


Hello,

i was not aware that i can change the DEP setting inside my application.
Or do i missunderstand your mail?

i have a DLL with a function that does some HW analysis and some crypting and generate a 256bit number based on the HW found. i have no source from the DLL.
This DLL works fine since about 10 years. but it traps in any MS-OS running in MS Virtual PC when DEP is enabled in the guest.
I want my app to report this scenario (when my app is started in a virtual PC with DEP enabled) and terminate.

thats all i want.
