VirtualProtectEx

[AlaXul]

Battlefield 2 uses VirtualProtectEx api to protect it's memory from modifications. Writing memory using WriteProcessMemory will not work. Applications such as MHS does not allow the area to be modified either. I have notice thought that Tsearch does work, and once Tsearch has modified it, then other applications can modify it as well. I assume it does something to defeat VirtualProtectEx, perhaps you could add this to MHS. Cheers!

It is easy to fix, however I primarily worry about the speed loss caused by having to call VirtualProtectEx() for each WriteProcessMemory().

I can fix this without VirtualProtectEx() while using kernel-mode, however, using only two instructions, which would cause no slow-down at all.

Of course, this means the feature would be exclusive to kernel-mode functionality, however that should be fine if I get the kernel-mode driver working with 100% stability.
