Here we go again! Many thanks to all who
answered my request for information about random numbers. I now have
another query. I have a program that generates a rectangular grid some of
which are coloured black and some of which are coloured white. When the
grid is generated, I want to choose one of the black ones and manipulate it in a
certain way. The problem I have is that the program tries to choose the
cell before the cells are coloured. I need to know how to make the program
wait until after the grid is drawn and coloured before selecting the cell to
manipulate. I'm sure this is easy but I don't seem to get it to
work. I either get a cell before the colouring is completed or nothing or
an error telling me there is a missing } at line2 col 0.
I know you people will know the answer to this and
I'm sure it's somewhere in the documentation but I'm unable to find
it.
