button of tool bar

HI,
i add a button to the internet explorer tool-bar with vbscript and register keys.

when i press the button it open a menu in the left side like the favorite button for example.
when pressing the new button it open an html file.

now my question:
i want to interact with the left side menu (not a part of the frame) and the main window. i try target = _main but its doesnt work.

how can i do that???

You might try posting this in the Classic VB forum, I think it might be more directed at them, but this thread kinda should be here as well.
