Hello I'm writting an apllication and i like to display and offscreen image.
However my code doesn't seem to work.
It compiles and runs properly but What i want is to associate the button of
the menu to switch an image (actually to add rectangels offscreen and bring
it to the front).
The following codes runs properly. You just need to create a file
images.properties and put some images in a folder called images.

I'd like to convert a double to a binary representation. I can use the
"&" bit operation with a bit mask to convert *non* float types to binary
representations, but I can't use "&" on doubles.
To get around this limitation on double, I'd like to keep the bits of
the double the *same* but change its interpretation to long. I can use
"&" on longs. I tried to use reinterpret_cast for this purpose, but it
returned zero every time.

I have read plenty about applying double buffering for animation and self
drawn forms. Is there a way to apply it to a form with many standard
controls on it (textboxes, labels etc) ?? I have tried using
myForm.SetStyles(ControlStyles.DoubleBuffer, True) however it has made no
impact on the drawing operation. Any clarification would be greatly
appreciated

Gents/Ladies, I'm doing (at least plan on ) lots of Reads and Writes
across a communication channel. I'm told that for the 'receive side'
it'd be prudent to implement a double buffering scheme to handle all
the asnychronous inputs.
Someone mentioned Herb Shutters book as frame of reference,
nonetheless, could someone provide sample code or - in effect an
outline of double buffering? I've perused the web but most references
are to...

I'm trying to convert a binary data feed into something more friendly. Some of the data is Int (and extracts successfully), but some is Double and doesn't. The below line of code gives harsh compilier warnings and then doesn't work correctly. I don't understand the warnings, sizeof(double) = 8. An integer has size 4 and it works fine.
// THIS Works!!!
unsigned int x_int = buffer<<24 | buffer<<16 | buffer<<8 | buffer;

hi
I need to do this (convert double to string) fast, safe and
portable. Is there any way to do this ?
Except the ways following:
1. C++ I/O stream, stringstream (and boost::lexical_cast)
2. sprintf (and its brothers)
3. any nonstandard C/C++ functions

I use a simple double array plus a variable to store the row size to
represent two dimensional data. I need to quickly copy this data to a
two dimensional array: double.
Currently I iterate through the double, one by one and place it into
the preallocated double. The arrays are large, and I'm doing a lot
of these. Thus it has become a significant bottleneck.
Can anyone suggest a faster way to convert a double + row size info
to a...

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...

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,...

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...
