Title: What is the difference between PAGE_EXECUTE and PAGE_EXECUTE_READ?
I found that the page with "PAGE_EXECUTE" attribute can be read, not any different between "PAGE_EXECUTE_READ".

[BuFF]

PAGE_EXECUTE > Enables execute access to the committed region of pages. An attempt to write to the committed region results in an access violation.

PAGE_EXECUTE_READ > Enables execute or read-only access to the committed region of pages. An attempt to write to the committed region results in an access violation.

Aslo what are you doing to need this?

Hi, I have read the MSDN.
But a page with PAGE_EXECUTE attribute (NO "READ" attribute) CAN BE READ.
If I use memcpy to copy a page with PAGE_EXECUTE attribute, it is OK, NO access violation.

There is a (NO "READ") attribute there is the PAGE_NOACCESS attribute which Disables all access to the committed region of pages. An attempt to read from, write to, or execute the committed region results in an access violation. Also if your using the CreateFileMapping Function this will not work
