I want to protect a piece of memory that contains PAGE_READWRITE but not PAGE_EXECUTE.

So I do this:
VirtualProtect(pointer($00401000),5,PAGE_READWRITE,op);

But it still has the PAGE_EXECUTE flag on it. Is it possible to remove the EXECUTE flag while keeping the READWRITE flag?

It's actually because, without PAE, or DEP enabled on the process, there are only two memory types: READ/EXECUTE and WRITE/EXECUTE. If you want to be able to remove the EXECUTE flag, launch the program under DEP, or go into your boot.ini file and change /noexecute=optin (the default) to /noexecute=optout.

Alternatively you could just use PAGE_NOACCESS, but then you'd have to handle all the reads/writes as well.

Granted, I just woke up, so I probably missed something here.

So is there a way of launching a program with DEP w/o changing Boot.ini.

Google won't give me an answer...

Right click on 'My Computer'.
Click on 'Change Settings'.
Click on the 'Advanced' tab.
Click on the 'Settings' button under 'Performance.'
Click on the 'Data Execution Prevention' tab.
Choose the second radio button.

I know that... But is it possible to enable it for 1 program. Though code? Not manual user settings?
