I need to control a command line program via python.
I first tried popen2 and 3 but I couldn't find a way to talk to the
subprocess interactively; that is, read some and then write some, and
read some more again... (suppose controlling an interactive shell
program) When I try this with popen family, it just hangs. I have to
close one pipe before reading from the other.
I know that there is a wonderful thing called Expect, but it's not...

Can someone help me figure out a way to open a form only once in an MDI app.
I have an MDI app that contains several forms. I use each form depending on
the type of document that the user needs to see, i.e. for documents of type
A, I use form A, for type B, form B, etc. Each document has a unique number.
I need the app to only show one document at a time, i.e. ifthe user tries to
open doc. 1 of type A, then open form A and load doc 1....

Hi,
I need to pass information between forms. i.e. a button is clicked on one
form1, form2 opens and has access to the contents of a text box of form1.
Then when the form2 closes it updates the text box on form1. I know this can
be done with global variables, but is there an actual way to pass a variable
from one form to another and then back?
Thanks

Build a stand-alone C# application that asks the user to click in a cell
in an Excel spreadsheet, and then displays the address of that cell in
the C# application. It seems simple enough, but the problem I'm
encountering is as follows:
In order for the user to select the cell from Excel, they must first
click once on the Excel window to give it focus and then their second
click is what changes the cell...

How can I tell via code if a Form is already open.
Each time my forms load I have some initialization code that runs, but if
the form is already open and hidden I don't want that initialization code to
run. Thus, I just want to unhide the form.
My thought is eveyrtime I go to load a form I could scan through all the
open forms in my project and determine whether the one I'm getting ready to
load is open or not.

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

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,...
