Calling function from another process

I have injected a dll into a process and I have a seperate process, which is my program, that I want to call a function that is in the dll (which is now injected into a seperate process). I am very confused as to how I would go about doing this.

Edit: Just realized this probably belongs in the Windows forum.

There's absolutely no simple way that you can do that.

Edit: thinking about it, you could of course fake a call to your process by stopping the process, and by modifying the stopped process's debug info, insert a call to your function [stuff your arguments on the stack, then the current instruction pointer, and then set the instruction pointer to the start address of your function].

It may help us if you explain what you actually are trying to do... But of course, it's probably making an auto-player for some game or some such.

That's what I thought. Well off to do it some other way, thanks.

See my edit above.

You can always VirtualAllocEx & CreateRemoteThread a new function into that process but I don't see the use of it since you already have your buddy (DLL) infecting that process, why not just call the function from DLL?
