Hello all,
I'm trying to write a program to be converted into a cgi file using
Network.CGI and Text.Xhtml, and I want to have random numbers in it. Sounds
simple, but I need to call the global random generator (I think) and I can't
do that in the CGI block, i.e.
cgiTMain = do
gen <- g
Hello there,
There's an odd error every time I try to run this code:
import Network.CGI
import Text.XHtml
import qualified Text.Html as H
import Database.HDBC
import Database.HDBC.Sqlite3
import System.Random

sqlReaderIO = do
handle <- connectSqlite3 "table2.db"
scoresSql <- quickQu
How does one change the font and size of text in a cells in a simpleTable?
As in, to change the height, one could state:
x = simpleTable [] [height "5"] exampleTable
Thanks,
Will

Hi All,
I've spent a lot of time trying to write a version of concat, which
concatenates lists of any "depth":
So:
concat'' [[[1,2],[3,4]],[[5]]] would return: [1,2,3,4,5]
The code is:
concat'' :: [a] -> [b]
concat'' ((y:ys):xs) = (concat'' (y:ys)) ++ (concat'' xs)
concat'' []
We were trying to make an addition function that, unlike the library one,
could add numbers of different types from the typeclass 'Num.' We originally
ran into a problem when trying to add (5 :: Integer) + 4.8, and were trying
to define a new function that would be able to get that:
(+') :: (Num a
