Hi, I'm trying to figure out a way to open a dialog box in the process I am trying to cheat on.

Inside the Dialog Box, I want to create some buttons that have the same IDs as some of the menuitems in the process. So, when I click on the 'Explorer' button in my dialog box, Explorer will show in my process.

I already know the menuitem IDs, but how do I create the dialog box?

Hitler, please help me!

Define "same IDs as some of the menuitems in the process"
A process can have multiple windows and each window can have the same ID's for menu items as another window yet be completely unrelated

anyhow, what specifically do you want to do?
Show a dialogbox when you click an existing menuitem in the process?
Show a dialogbox unrelated to the rest of the game
Add a menu item to an existing window ?
Add a button to the gui of an existing window ?

It would be nice if I could add a menuitem to the window.. Razz

I found the IDs of some of the menuitems in the program when I opened it with ResHack. I even edited one of the dialog boxes with ResHack, and added some buttons that have the same IDs as the menuitems. When I opened a game with the program, I was able to open the dialog box by pressing the screenshot button. The buttons I had added earlier with ResHack inside of the screenshot dialog box worked! The only problem, is that before I join a game, the game doesn't load because it checks to see if the resources have been edited. I'm trying to edit (or create) a dialog box while the program is running, after the check that looks to see if the resources have been modified.

I have no experience with resources, but try a dll injection. In the dll use setWindowLong to override the wndproc so you get full control over the message handler

Then find and modify the menu (or just replace it with the same id's) and when it's the ID you want handle it accordingly.
Also, you might be able to use resource specific functions once you have the wndproc, but I have no clue

first originalfunc=GetWindowLongPtr(handle, GWLP_WNDPROC) to get the original wndproc
Then SetWindowLongPtr(handle, GWLP_WNDPROC, (LONG_PTR)newwndproc))

and in newwndproc handle message and do stuff and when you're done do a CallWindowProc(originalfunc, handle, msg, wparam, lparam)

(I notice there is a DWLP_DLGPROC as well, if you're more confortable with that, look into it)

But yeah, you'll need to know how to do GUI in C first
