Hello out there! I was wondering if anyone would please help me with
a little problem that I have in developping a PM application.

I am developping an application in PM which is to have the look and feel
similar to a spread sheet with rows and columns of data. The rows and columns
should be similar to text entry fields where the user can type in data.
Now, what I want to do is to be able to select an entire row, or column
or, groups of rows or columns at a time. Additionally, I would like to
be able to display the selected rows or columns of the "spread sheet"
as being highlighted, say, in reverse video.

I have been thinking of a number of different possibilites:

1) A conventional PM list box with text fields.
   - Selected items in a list box do get highlighted in reverse video,
     but can one make a 2-D grid in a list box? (None of the literature
     mentions 2-D grids in list boxes).

2) A dialog window with a 2-D grid of text entry fields.
   - PM does not seem to allow you to set the colors of an individual
     (or many for that matter) text entry field object(s).

3) Defining my own object class (similar to what Petzold does with
   the square button)
   - Probably the best and only way of doing this, but I haven't jumped
     into the details yet.

My question is, has anyone ever tried any of these ideas or have
any further information? Any input is welcome.

Thanks!

Marco...
