tclODBC + tclhttpd  edit

JM 22 Jul 2011 - I was just playing a little bit with tclhttpd by putting the following code on the file: \htdocs\cgi-bin\test.cgi
 package require tclodbc
 set driver "Microsoft Access Driver (*.mdb)"
 set dbfile "C:\\Program Files\\Microsoft Office\\office11\\samples\\Northwind.mdb"

 puts [html::h3 "getting info from Access through tclODBC..."]
 puts "<table border=1 cellpadding=4>"
 database connect db "DRIVER=$driver;DBQ=$dbfile"

 foreach rec [db "select EmployeeID,LastName,FirstName FROM Employees;"] {
   puts "<tr>"
   foreach field $rec {
     puts "<td>$field</td>"
   }
     puts "</tr>"
 }
 puts "</table>"
 db disconnect

just after the following existing lines:
 puts [html::h1 "Hello, World!"]
 puts [html::h2 [clock format [clock seconds]]]

and I got a dynamic page that queries the database that comes as a sample with the Microsoft Access installation.

you can get there by means of the CGI link on the home page, then through the Sample form posted to test.cgi and finally hitting the "Submit Query" button.

gnuplot and the tkcanvas terminal type  edit

JM 26 Oct 2013 - I dont know why, but I had to put some puts commands after the source command to make it work, if not, I was getting an error saying that the gnuplot commmand did not exist
 console show
 #set gpexe C:/gnuplot-4.0/bin/pgnuplot.exe
 set gpexe "C:/Program Files (x86)/gnuplot/bin/pgnuplot.exe"
 #set outfile C:/data/resultat.tk
 set outfile "C:/Users/jmoreno/Documents/code/gnuplot/resultat.tk"

 set gp [open "|\"$gpexe\"" r+]
 puts $gp "set term tk"
 puts $gp "set output '$outfile'"
 puts $gp "set noborder\nset zeroaxis"
 puts $gp "set xtics 1\nset ytics .5"
 puts $gp "plot \[-2:2\] atan(x)"
 close $gp

 pack [canvas .c]
 source $outfile
 puts $outfile
 puts [info commands gnu*]
 update
 gnuplot .c

JM 7 Nov 2014 - Looks like the real fix is this (just waiting a little, to let pgnuplot.exe to completely close):
 console show
 #set gpexe C:/gnuplot-4.0/bin/pgnuplot.exe
 set gpexe "C:/Program Files (x86)/gnuplot/bin/pgnuplot.exe"
 #set outfile C:/data/resultat.tk
 set outfile "C:/Users/jmoreno/Documents/code/gnuplot/resultat.tk"

 set gp [open "|\"$gpexe\"" r+]
 puts $gp "set term tk"
 puts $gp "set output '$outfile'"
 puts $gp "set noborder\nset zeroaxis"
 puts $gp "set xtics 1\nset ytics .5"
 puts $gp "plot \[-2:2\] atan(x)"
 close $gp
 after 1000
 pack [canvas .c]
 source $outfile
 #puts "we are at: [pwd]"
 #puts $outfile
 #puts [info commands gnu*]
 #update
 gnuplot .c
