Re: Controlling who can run an executable

Have the program check for a file hidden somewhere on the computer.
For instance, if the file dummyfile.dll doesn't exist in the
windows/system32 folder the program just doesn't start. And when you
install the program on her computer just add this file. And if anyone
copies the program the can't run it on any other computer because they
doesn't know the name of the file that's needed to start the program.

How about that?

Make Tkinter child window active

[Svennglenn]

How do i make a child window "active" like the root window?

from Tkinter import *

def open_child():
c = Toplevel(root)
c.title("Child window")
c.geometry('200x160+230+130')

Label(c, text="Child window").grid()

root = Tk()
root.title("root window")

Button(root, text="Open child window", command=open_child).grid()

When the child windows opens i would like it to be active like the

replace text in unicode string

[Svennglenn]

I'm having problems replacing text in a
unicode string.
Here's the code:

# -*- coding: cp1252 -*-

titel = unicode("ä", "iso-8859-1")
print titel
print type(titel)

titel.replace("ä", "a")


When i run this program I get this error:

titel.replace("ä", "a")
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in position 0:
ordinal not in range(128)


How can i replace text in the Unicode string?

Trouble saving unicode text to file

[Svennglenn]

I'm working on a program that is supposed to save
different information to text files.

Because the program is in swedish i have to use
unicode text for ÅÄÖ letters.

When I run the following testscript I get an error message.

# -*- coding: cp1252 -*-

titel = "åäö"
titel = unicode(titel)

print "Titel type", type(titel)

fil = open("testfil.txt", "w")
fil.write(titel)
fil.close()


Traceback (most recent call last):
  File "D:\Documents and
Settings\Daniel\Desktop\Programmering\aaotest\aaotest2\aaotest2.pyw",
line 5, in ?
titel = unicode(titel)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe5 in position 0:
ordinal not in range(128)


I need to have the titel variable in unicode format because when I
write
åäö in a entry box in Tkinkter it makes the value to a unicode
format
automaticly.

Are there anyone who knows an easy way to save this unicode format text
to a file?

Closing dialog window in Tkinter

[Svennglenn]

Hi

I'm creating a program in Tkinter and I would need
help to create a "close button" for dialog windows.

One of my typical dialog windows look like this:

def show_window(self):
top = Toplevel()

Label(top, text="Some text").pack()
Label(top, text="Some more text").pack()


So what code do i need to insert to create a button that
can close this window? If you need to look at some more
code from the program to be sure please till me.

Problems programming with Tkinter

[Svennglenn]

Hi !

I'm trying to create a graphical program using Tkinter.
The program is supposed to save a string the user defines
as a filename. I've made it work with the the first button
in the program that's named "Spara ett värde i en sträng till ett
filnamn", that's swedish for "Save a value in a string as a file name".
The button "Skriv ett värde till filen" (swedish for "Write a value to
the file")

But, i want the program to open a new dialogue when i press the button
"Visa ruta" and in that dialogue will be a field where you can enter a
value directly in the program, but a can't get it to work because is
don't know how i shall do to open a new dialogue window in the program?
Is there someone who can help me with my problem?

Here's the sourcecode for my program:

from Tkinter import *
class App:


def __init__(self, master):

frame = Frame(master)
frame.pack()


self.hi_there = Button(frame, text="Spara ett värde i en
sträng till ett filnamn", command=self.say_hi)
self.hi_there.pack(side=LEFT)


self.skriv_varde = Button(frame, text="Skriv ett värde till
filen", command=self.skriv_varde)
self.skriv_varde.pack(side=LEFT)

self.visa_ruta = Button(frame, text="Visa ruta",
command=self.visa_ruta)
self.visa_ruta.pack(side=LEFT)

def say_hi(self):
print "Sparar fil"
S = "filen.fil"
output = open(S, 'w')
print "Filen sparad"

def skriv_varde(self):
print "Skriver värde till filen"
myfile = open('filen.fil', 'w')

myfile.write('Ny mening')
myfile.close()
print "Värdet till filen skrivet"


def visa_ruta(self, parent):

top = self.top = Toplevel(parent)

Label(top, text="Value").pack()

self.e = Entry(top)
self.e.pack(padx=5)

b = Button(top, text="OK", command=self.ok)
b.pack(pady=5)


def ok(self):

print "value is", self.e.get()

self.top.destroy()


root = Tk()

app = App(root)
root.mainloop()
