Just out of curiosity what's wrong with using ReadProcessMemory and WriteProcessMemory in windows.h other than the fact it alerts some security software? I'm using it to pass all types of data currently, and it works better than using DX8 and globalPtr IMO..under Devc++

Passes strings from my DLL in just two lines of c++ code. Not even using pointers, just a global.

What's wrong is that you are bypassing the OS memory security - once you gain access to the memory of another process, then all memory security is gone for that process.

Take a look at using shared memory instead - it's a way of sharing a region of memory between 2 or more processes but it stays within the security model.

I also figured it eats up resources too because it's going through the kernel directly. It's only useful for game trainers and security stuff I guess.

I'll go look at shared memory or whatever. Just looking for a easy way around using directx and bulky 3rd party MS VC++ and/or .NET libraries to pass strings from a dll.
