Possible to inject new menus into GUIs?

[chants]

Injecting the menu is not so hard it's just a Windows message as long as you have a way of getting the handle and have a way to locate where you want it. You could even use a resource editor to do it if the menu is statically created. But you need a click action handler and the logic in there would require you to know a good deal about the data structures of the underlying program. It's definitely possible but in complex apps can be prohibitively time consuming to figure out. Like adding the save menu back into IDA Pro demo for example. A complex database format like that has a large amount of C code to save with data structures gathered from all over. Sometimes it's very difficult. So it depends on the context if it is worth it or not.
