hey ppl, in my project which is actually developing a COM addin to ms excel
using c#.net, I am creating my UDFs which are working fine.

But now, I want to be able to show tooltips to these UDFs whenever some one
starts using them in an excel cell in the form of '=my_udf(......)'. I want
to display a tooltip that talks about the number and type of the arguments
'my_udf( )' takes.

Can anyone guide me through this?

Regards,
