Using VisualBasic

I have currently created alot of PolyPolygon regions which i use to fill and outline alot of reservation, now what i need is to add text to these. I figured that by using the CreateFont, SelectObject and SetTextColor, i can print different types of font and colors on my grid.
Then by using DrawText API i can select a rectangle to clip the text within. So this is where iam stuck i now need to get the largest Rectangle from within a PolyPolygon area, actually what i need is to find the largest horizontal rectangle within every part of the PolyPolygon region which are not connected.

Can someone give me an example of doing both or just the first ?
