For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
tcl/tk & C++

Hi all! I wrote small programm that combine tcl/tk & C++. But window of wish-interpretor is blocked (entry field & button is disabled). Please take a look at my source and fix it...(as it posible).

#include <tcl.h>
#include <tk.h>
#include <iostream.h>
#include <string.h>
#include <stdio.h>
int Tcl_AppInit(Tcl_Interp *interp);
int main(int argc, char *argv[])
Tk_Main(0, argv, Tcl_AppInit);
int Tcl_AppInit(Tcl_Interp *interp) {
     char inbuf[100];
     char tcl_expr[256];
     int error_code;
cout << "Expr? ";
cin >> inbuf;
if (Tk_Init(interp) == TCL_ERROR)
sprintf(tcl_expr, "set answer [expr %s]", inbuf);
error_code = Tcl_Eval(interp, tcl_expr);
char mas[] =
     "entry .e -textvariable answer\n"
     "button .b -text \"Exit\" -command {Exit}\n"
     "pack .e .b\n";
error_code = Tcl_Eval(interp, mas);
return TCL_OK;
return TCL_OK;

I suspect that you have to do something different to a normal embedded Tcl program to allow your C program to deal with the main even handling loop of Tk ... but it's not something I do every day and my reference book that would tell me (do you by any chance have John Ousterhout's book?) is thousands of miles away this week.  Hopefully my thoughts will set you off in the right direction, and you'll find something in the documentation that you've already used to get this far!
