Hacking calc.exe

[jrsanz1]

Need help hacking into calc.exe. What I need to accomplish is to grab data, functions, events from calc.exe. Mainly what I want right now is to create an application to run calc.exe grab the data that is displayed on the text box of calc.exe and display it on a label in my application.

I have been studying hooks, but I still do not have a clear understanding of how I can do this with hooks, if I can get an example or suggestions of how I can accomplish this task I would greatly appreciate it.

Thanks

I understand that “grab data” means to get a copy of the Calc’s display. But what is “grab functions”?
Also, before attempting hacking of any kind, please consider automation.
