I am developing an application automating excel from vb.net

Rather than use vb win forms with complex calculations, which will be difficult to maintain, I am presenting the user with an Excel spready as his input form. This spready does a lot of work behind the scenes for the user and is working very well

However it would be good if the user could hover the mouse over a cell and a tooltip appear (as if it were a win form) to assist his thoughts with the input

Obviously I could set xl comments on all input forms but this would not be as slick as a tooltip type presentation
Has anybody been here

Yous hopefull
