Hi,
I'm using Python with pygtk and have this problem - I have read the
contents of a file into the text buffer with this code,
infile = open("mytextfil e", "r")
if infile:
string = infile.read()
infile.close()
textbuffer.set_ text(string)
As a test, I tried to write the buffer back to a file with this code
but did not work,
outfile = open("newbanned sitelist", "w")
outfile.write(t extbuffer.get_t ext(0, 1000,
include_hidden_ chars=True))
outfile.close()
What I want to know is how do I write the contents of the text buffer
back to a file?
Thanks 7 5302

Oooh, guessing games! I love guessing games!
Let me see... did it reboot your PC?
Did Python crash?
Did you get an exception? Maybe something about not being able to open
the file for reading? Or perhaps disk full?
Did you get something unexpected in the file? Maybe an empty file?
I'm guessing... it erased your hard disk. Do I win?

Note that "if infile" does nothing: either the open succeeds and you get a
file object which is *always* True, or the open fails and raises an
exception and the code below never executes.

I just included file opening code just to show how i read the file
into the text buffer - I have no issues with this as such. Problem is
only with the writing of the text buffer back to a file. When I try to
write the buffer to a file it gave the following,
<gtk.TextBuff er object (GtkTextBuffer) at 0xb7cff284>
Traceback (most recent call last):
File "./configbox.py", line 78, in ?
TextViewExample ()
File "./configbox.py", line 53, in __init__
outfile.write(t extbuffer.get_t ext(0,1000,
include_hidden_ chars=True))
TypeError: start should be a GtkTextIter
How can I use outfile.write() to wite the contents of the text buffer
correctly?
Thanks

No

No - it runs on nix

File read ok for input, its the file write thats the problem

Yes, a rabbit popped out of the floppy slot - amazing!

Sorry, you lose....are you a Windows user?

Well, duh. I know that -- that's what your first email said.
Don't tell us there's a problem. Tell us what the problem is. Duh.
>Did you get something unexpected in the file? Maybe an empty file?

You know how your teachers said "there are no stupid questions, only
stupid answers?" They lied.
Perhaps you should go away and read this before asking any further
questions. http://catb.org/esr/faqs/smart-questions.html
>I'm guessing... it erased your hard disk. Do I win?

Sorry, you lose.
I really don't know why you're casting aspersions on the intelligence of
Windows users, when you're the one posting a stupid question. Do I really
need to spell it out?
We can't tell you what the solution to the problem is if you won't tell us
what the problem is. If you get an exception, post the exception. If
something unexpected happens, tell us what it was. We're not mind-readers.

Ah, well there's your problem. start should be a GtkTextIter, just like
the exception says.
Question for you: in the line of code in the traceback, which function
takes an argument called "start"?
How can I use outfile.write() to wite the contents of the text buffer

Your problem isn't with outfile.write() .

Solved!
# Output file
outfile = open("newbanned sitelist", "w")
outfile.write(t extbuffer.get_t ext(textbuffer. get_start_iter( ),
textbuffer.get_ end_iter(), include_hidden_ chars=True))
outfile.close()
I'm new to Python and GTK and may not be asking the right type of
questions initially. I programmed with C many many years ago and my
programming instincts are very rusty so still feeling my way again
with this stuff. Apologies for the sarcastic reply earlier but i felt
your initial reply to be sarcastic. I also did research this problem
but seemed to be getting nowhere - thats why I asked for the groups
help.
Anyway, thanks to all that replied via emailed and in this group.

<?
$fp = fopen ("binary.dat", "wb");
$buffer = 12345;
fwrite ($fp, $buffer);
fclose($fp);
?>
That creates a file 5 bytes long that contains the text data "12345", but I
need it to save that value as 32-bits instead (so the file would just be 4
bytes, with the contents being 0x39300000).
