Hi there,
I would like to open an existing file that contains some lines of text
in order to append a new line at the end of the content.
My first try was:
>>> f = open('/tmp/myfile', 'w') #create new file for writing
>>> f.writelines('123') #write first line
>>> f.close()

I have a reusable web application (e.g. portal). I often do a project copy
to create new virtual apps. This works fine.
Now I want to take that reusable app (not the solution and it's projects)
and just add a few new user controls to it. I do not want to copy the
entire reusable application (solution, projects, etc) and add my new user
controls.
What is the best practice for taking an existing web application directory

I have one form that has two buttons. I want the first button to exit the
form, and the second button to open a specific file on my C: drive.
I can get the form to close (Woo!), but can anybody tell me the code needed
to open an existing file on my computer. I've spent all morning looking on
the net but have had no luck.
The file, if it makes any difference, is a .pps
Thanks in advance people.

Hi,
I need to output result of my query to txt file. So I'm using -o
parameter, for example:
osql.exe -s (local) -d database1 -U sa -P sa -i 'c:\\queryFile.sql' -o
'c:\\output.txt'
But it clears existing output.txt file first and then outputs the
result, while I need to append the result of my query without clearing
existing file content. Is it possible ?

In my Access database, I have a button on a form that copies a set of existing Word documents to a location (associated with the record on that form).
However, I don't want an existing file to be overwritten (as it currently happens), but rather I want to make a copy (filename + "(2)" or "(3)", etc., as appropriate).
Here's the code as it stands:
Function Public_Copy_Files(strChartNum As String, strAccount As String)

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
