Manipulating Menus in Windows Forms

[The_Mega_ZZTer]

Hey, I'm trying to use AutoIt to add tabbed functionality to Notepad. My attachment has what I've got so far... "dumb" tabs. It requires the latest AutoIt beta.

To use the script I've attached to see what I've done so far, run it and it will launch notepad and add it's tabbar. It's designed for and was tested on Windows XP Notepad but hopefully it should work on earlier versions too.

Of course, Notepad isn't "tab aware" so I have to write my own load/save functions in AutoIt, and then the problem is how to supress Notepad's load/save functions and use my own.

What I want to do is disable/hide Notepad's menus, in whole or in part, and replace it with my own menus which I can then catch events for. If this proves to be impossible I'll probably have to settle for making a toolbar with open/save buttons.

Anyone have any ideas?
