How can I inject this into the process? It needs to be loaded when the user wants, and the patchmydata won't load if these patches are in the exe eg. i open it and in olly do save to exe with patches then load it crashes. There is no other solution except to do it at a random time. I also want to make sure to have it as a separate exe, as thats what I need to pm them. SO... can anyone make an example? Or is this impossible? Thanks in advance and thanks for reading!

Import WriteProcessMemory and write the array to the target process:

You can get a valid handle to use from the Process namespace rather then bothering with OpenProcess:

So how would I for example change the function at 0045B87 to NOP?
