** tclODBC + tclhttpd **
''[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 **
''[JM] 26 Oct 2013'' - I dont know why, but I had to put some puts commands after the [source] command to make http://wfr.tcl.tk/273%|%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
