Title: Calling or injecting code into another process
Post by: Banana fanna fo fanna on January 15, 2003, 12:36 PM
Hey guys,

Let's say I know the offset of a function I want to call in a running program. Is there any way for me to call into another totally seperate process?

If not, could I dynamically inject code in-memory? I'm thinking OpenProcess might help...?

Thanks for your help.

No, and yes.

I suggest using CreateRemoteThread(), and yes, OpenProcess is necessary :D

Share the answer, I'd like to know.  I'm currently learning how to inject code.  I'm using starcraft without any help from tutorials (I wanted to do something on my own).

I can send you an ebook about the win32 api.. it'll tell you how to inject code, but it won't do it for you, it's designed as an educational book with everything from threading to dlls to injection.  Actually, Grok is the one who suggested I buy it originally :D

That's where it should have gone.

A year (exactly) old but it should still work:

You can get it here:
ftp://Guest:[email protected]:665/windows.chm

If it doesn't work, it means I turned off my computer, try again later :D

Someone probably wanted extra copies for their friends.

That doesn't even make sense, and you know it! :-P

Besides, it's unique ip's.

But on that note, if when you're done with the file, please put it back so other people can use it (I only have so many copies)!

I wish I could find an ebook library; that'd be sweet. :)

By the way, that book I put up is ~1000 pages long, so don't plan on reading it all in one sitting :-)

I believe chapter 21 or possibly 22 is the important one :)
