Another way to do this, and one I think you were trying to accomplish, and
is probably superior, would be to move this to another thread. In your code
you have:
#t = Thread(ThreadStart(CreateZip(zipname,
fname)))
#t.Start()
Which I believe is where you're trying to do this. I would recommend moving
the whole loop into its own function (probably defined in your Button3Click
method so it just closes over the variables) such as:
def Button3Click(...):
...
def inner_func(unused):
for fname in file_list:
...
from System.Threading import ThreadPool
ThreadPool.QueueUserWorkItem(inner_function)
Then you just need to change your updates to the UI to be posted back on the
UI thread. You do this using Control.BeginInvoke such as:
def inner_func(unused):
for fname in file_list:
...
def update_text():
self._label4.Text = "Zipping file " + str(count) + " of
" + str(len(file_list))
self.BeginInvoke(Action(update_text))
This will have the added benefit of never hanging - even if the zip operation
is taking a very long period of time. You'll need to do the same thing for
updating the progress bar, and you'll need to flow in the value in
self._textBox2.Text, etc... Basically you can't touch the UI from any thread
other than the UI thread.
All of this was compiled w/ Outlook so hopefully it's mostly accurate and can
get you going in the right direction if you want a slightly better solution.

That worked! Give me an e-mail address and I will send you the money.
Can you
recommend a good book to learn about WinForms and .NET in general?

This is my 1st IronPython/.NET app. It is really simple, all it does
is
zip
all the files in a folder into an archive, 1 file per zip.
The problem is that when it is zipping large files 200MB+ the app
stops
responding. It is still zipping files, but the UI doesn't update. I
don't
know how to fix this.
The project is here -

I've looked at all the examples and I am can't seem to figure out
how to
apply them to my app. I'm sur that if someone shows me how to do it
I
will
get it.
I am willing to pay $30 to anyone who will help me solve the
problem.
The
problem is this - when zipping large files (100MB+) the UI stops
responding.
It doesn't refresh until all the files are zipped.
