Make VS2008 show value of object in tooltip while debugging

Not sure if this should have been posted here or not. Hope it is good enough here.

Have you ever noticed (if you use VS2008 -don't remember about earlier versions-) how you get the value of a CComVariant object (I think VARIANT's too) nicely presented in a tooltip whenever you debug and hover over the variable holding the object? If the VARIANT is VT_DATE, the tooltip shows the date and time nicely formatted; if it is VT_BSTR, you get to see the string contained, etc.

In C#, this tooltip pretty much contains the returned string from the ToString() method. Does anybody know what controls this in C++? I mean, can I make my classes output its value in the tooltip in such a nice way?
