Hi,
I'm trying to use python to create GUI wizards, i.e. sequences of dialog
boxes with <BACK and NEXT> buttons. Since I want to re-use some of the
dialog boxes in different wizards, I want to have a main function which
calls each dialog box, much like this:
def select_item():
"""runs GUI wizard to select item"""

Hello all. I have been given mock-ups (in static HTML) of some pages
for a site I am working on. The client would like these pages to look
exactly as they do now. The problem is that the content is dynamic, it
comes from a database.
My question -- with CSS (because with HTML tables I don't think it's
possible) how can I make my text "flow" in two columns? eg. If there
are 100 lines of content, I would like 50 to be in the 1st column, and...

Hi. I'm working with an app that uses exceptions for control flow.
These are code blocks where exceptions are thrown/caught regularly. A
couple hundred exceptions occur per hour and they're caught close to
the point of origination. I'm trying to decide whether to refactor...
What is the cost of throwing an exception in the CLR - relative to,
say, a conditional statement? Are we taking talking 1+ orders of
magnitude? Is there...

Exceptions must not be used to control program flow. I intend to show that
this statement is flawed.
In some instances, exceptions may be used to control program flow in ways
that can lead to improved code readability and performance.
Consider an application that must eliminate duplicates in a list.

Hi,
I've read a few contradictory statements on how to do flow control between
methods. Main problem is that I've seen recommendations (or "standards") to
*not* use exceptions for flow control, but also that exceptions now replace
the need to pass return codes between methods.
So whats best to use?
Thanks.

a user control, and a module:

Hello, friends,
We created a drop-down menu bar and a show/hide calendar web user controls
mainly using javaScript and html.
However, they both have the problem that they are not dispaly as the top
controls in IE browser. Rather, text box, file field, and etc. are on the
top. As a result, our calendar and drop-down menu bar were "cut" here and
there wherever there is one of those boxes.

Hi,
I have been looking for a good way to convert python code into a
control flow graph.
I know of Python functions that will convert an expression into an
abstract syntax tree (i.e. ast = parser.expr('(x+5)*5') then t =
ast.totuple() then t), but I am not sure how to obtain a CFG.
I've gone through the compiler and it has code that converts the AST

Howdy,
I have a datalist which is displaying a list of categories and their
associated sub categories in secondary datalists. Works great in a single
column. Unfortunaly when i switch it to repeatcolumn = 2 (or three or
anything over 1) , the data is displayed quite erratically, for example
category 1 category 3
sub 1 sub 1
sub 2

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
