I having a problem reading all characters from a file. What I'm trying to
do is open a file with "for now" a 32bit hex value 0x8FB4902F which I want
to && with a mask 0xFF000000 then >> right shift 24 bits storing in result
then printing the result.
I thing a while or for loop is needed but I'm not quite sure how to go about
it. How do I step through each character in this case and store it for use
and passing to another function.

Hi Everybody!
I have 2 different processes/application. One is writing to a file and
another is reading from it. For some reason the code doesnt seems to
work and gives mscorlib.dll IOException error "This file is being used
by another process".
Both the applications are in C#.
P.S. Even if I try to open the file with NotePad (while my server is
writing data in the file)it gives the same error.

I'm using StreamWriter to write to file and at the same time I'm using the
StreamReader to read from the same file.
Doing that cause an exception when I'm trying to create the StreamReader
when the file is already opened fro writing by the StreamWriter.
How can I write and read at the same time to the same file?

Thanks

I have been playing around with a subclass of dict wrt a recipe for
setting dict items using attribute syntax.
The dict class has some read only attributes that generate an
exception if I try to assign a value to them.
I wanted to trap for this exception in a subclass using super but it
doesn't happen.
I have read Guido's tutorial on new style classes and Shalabh's
tuturial on new style attributes and methods, and thought

What i want actually is that when i right click on an element in my
HTML file, select "properties" and then build the style of that html
element, i want that the details about the position, colors and all
other parameters of the style will be held on the corelated CSS file
and that VS will define a class name automaticly.
what i am doing now is to copy the style properties from the HTML tag
to the CSS file manually.
Thanks.

Hello PHP Group,
I am having trouble setting permissions correctly so that the
magickwand api (php 5.2) can read and
write images. I usually read a file from one directory, create a
magickwand resource from that file,
and transform the image, and save the new image with a new name to a
different directory.
I have seen that my file and folder permissions when set incorrectly,

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:
