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.


pscp

JM 7 Sep 2013 - pscp from the putty family of tools, see also plink

  • The following script runs on a windows machine
  • Getting a file from an ubuntu machine
  • The file will be copied to c:\putty in this case
 console show
 proc action {} {
   cd c:/putty
   set f [open "|\"pscp.exe\" -l jorge -pw yourpwd [.from get]:[.path get] ."]
   puts done
 }
 entry .from
 entry .path -width 50
 button .button -text get -command action

 .from insert 0 [email protected]
 .path insert 0 /home/jorge/sample.txt

 pack .from .path .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 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

Expect

JM 18 Feb 2014 - The following example was good for me to try the basics
Remote input-output with Expect

XML Post HTTP

JM 26 Feb 2017 - from:
https://groups.google.com/forum/#!topic/comp.lang.tcl/B6afDJQg8LA

 package require http
 console show

 set organism_name "nipah"
 set xml "

 "
 set url "http://www.rcsb.org/pdb/rest/search"

 set tok [::http::geturl $url -query $xml -type application/x-www-form-urlencoded]
 set rep [::http::data $tok]
 puts "[::http::status $tok]"
 puts $rep

 ::http::cleanup $tok
