Open file by dragging and dropping on toolbar button

Hi,

I've added buttons for MS Office and Textpad to my toolbar. How do I open a file by dragging and dropping it on one of these newly added toolbar buttons?

Thanks,
Ben

Edit the button like this (done by clicking on the icon while holding down the Alt key):

"C:\Program Files...\YourEditor.exe" "%1"

Of course the path has to be the right one, depending on where you have your Microsoft Office installed.
