Hi guys. I've written code to embed an ICC profile in a TIFF image, and I
think my IO operations are slowing things down. It is taking about a second
to embed each tag in 7-meg TIFF files. Doesn't sound too bad until you try
doing it to 500 files. Basically what I am doing is this:
1. Read header from image, add 12-byte tag to header, and write to a new
TIFF file
2. Update all the offset pointers in other tags in TIFF header to...

Hello,
I wonder if anyone could help me.
I'm using vb.NET and I'd like to read a binary file, byte by byte, and
then write to another file (making a duplicate, identical file).
I'd then like to modify the program to take the integer value of each
byte and say, add or subtract an integer from it, with the result
still being an integer from 0 to 255. Then write another file that is

The following code will enter an infinate loop when in ReadChars. I can only
make it happen when reading a Stream and with this particular XML. If I use
the ReadInnerXml call rather than my own ReadElementBodyAsXml the code works,
but is less efficent. ReadElementBodyAsXml is required by my application
with .Net Framework 1.1.
The code breaks on the second call to ReadElementBodyAsXml with the inner xml:

I've stumbled upon unexpected behavior of the .NET 2.0 System.Xml.XmlWriter
class when using it to write data to a binary stream (System.IO.Stream). If
the amount of data is less than a certain value (which varies depending on
the data being written), characters not available in the encoding specified
in the Encoding property of the XmlWritterSettings instance used to create
the XmlWriter are being written to the resulting XML document as...

I have some .NET 1.1 code that utilizes this technique for encrypting

In .NET 2.0 this approach is not fully supported (a .NET 2.0 build

resulting decrypted file will be corrupted. I tried encrypting a .bmp

When using System.IO.FileStream, I write 8 bytes, then seek to the start of
the file, does the 8 bytes get flushed on seek and the buffer become a
readbuffer at that point instead of being a write buffer?

If the filestream is opened for write access then it still keeps its write
access.
If you seek to the beginning after writing 8 bytes, and write some more
bytes, you overwrite the original bytes.
I don't believe there's any flush occurring on a seek...whether any buffers

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:

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,...
