Adding simple feature to Browser Helper Object written in Delphi

I am writing a very simple IE Browser Helper Object in Delphi 7 and I need some help to add a feature. It is probably a matter of adding only a few lines of code. Here is the point: I first added 5 toolbar buttons to IE and linked them to the COM GUID of my [login to view URL] and then implemented some methods to intercept the events. Now everything works, the Exec method is called when a button is clicked, BUT I DON'T KNOW WHICH OF THE 5 BUTTONS is calling the Exec method. And now that's what I need: A way to know which of the 5 buttons is calling Exec. I am attaching the source code. Search for the string 'Which button was pressed?' to go straight to the point where I need the information. (All the parameters there seem to be 0 and nil...) I also implemented the method SetSite, perhaps that's where this information can be recovered? Thank you!
