Hi everyone,

I need to know how to program the following things in the source code (not
setting options or preferences)  with gnumeric fast:

1) How to change the color of a cell?
2) How to get the value in a cell?
3) How to pop up a dialog box?
4) How to grab values user enter in a dialog box?
5) How to use selection of cells for entering the cell locations into a
field?

That is all for now. Any help is GREATLY APPRECIATED. 

REgards, SERNAM
