Can You get Handle based on Screen Coordinates?

I posted an earlier request but it may have been too in depth for some reason. I only need to know the following?

1) is it possible to get a windows handle via screen coordinates I supply
2) obtain the text data from that window via that handle if it is a scroll bar controlled window within IE.

I can get the Handle and coordinates of the main IE window and can calculate the location of the 2 text windows I need the data from as they are always in the lower left, and lower right corners of the Main IE Windows Client area.

I am used to doing VBA rather than VB and was wondering if I am even able to do this?
