I have a file I'm writing to and then changing the size of it to the size of text written to it something like:
FILE * file...
I get all the data from the file and change the file's size to the data's size but it differs. The string's size is smaller ...

On most ....
The reason is because "r" or "w" will translate CRLF, while "rb" or "wb" will treat the data as binary .
Perhaps it's CRLF? Beware of:
fopen(filename, "r") vs fopen(filename, "rb") ,
and likewise
fopen(filename, "w") vs fopen(filename, "wb") .

It won't get smaller than the initial heap size by the parameters -XX:MinHeapFreeRatio= and -XX:MaxHeapFreeRatio=, and the total size is bounded below by -Xms and above by -Xmx....
The initial heap size is the minimum heap size.

I'm wondering if there's a difference in using size_t and container::size_type?
What I understand is size_t is more generic and can be used for any size_types..
Is container::size_type more optimized for a specific container though?

So for the standard case container::size_type is preferable....
The standard containers define size_type as a typedef to Allocator::size_type (Allocator is a template parameter), which for std::allocator is defined to be size_t .

Can we change the size of size_t in C?

Answer Snippets (Read the full thread at stackoverflow):
It probably is typedef unsigned long long size_t; and....
size_t is defined in <stddef.h> (and other headers).
It is a typedef for a suitable unsigned integer type .
But why would you even want to do it?
size_t is not a macro.

A byte is a byte is a byte -- 8 bits, no more, no less .
The size of numeric types is generally a multiple of the machine word size.
Of depends on what you mean by relation.

Looking at the properties for a windows file I get two attributes, Size & Size on disk and Size on disk is always larger.
What do these two metrics mean?

In "CSS: The missing manual" the author says that font-size: medium (or other size keywords) sets the font relative to the browser's base font size.
But what I'm seeing in FF2 and IE6 is that it sets the font size to what I specified in the .CSS HTML ...

Only if you don't specify a font-size 2.1 specification :
The 'medium' value....
I think if you set a default size to a element like a container or the body, then any relative font-sizes in the children are based on the parent elements.

On both pages,the font-size is 10pt,
but on one page the font size looks obviously bigger than on the other page,
what can be the reason for this?

It will tell you the actually font size with the 'Display element information' option.

I used a class which derives from CListBox, and create it with following style:WS_CHILD|WS_VISIBLE |LBS_OWNERDRAWFIXED | WS_VSCROLL | WS_HSCROLL
I expect the ListBox's item to be have a fixed size, not affected by the size of the list box. So I override...

Also, have you considered the points made in MFC Technical Note 14 .
The control's size changes.

Hi, Is there a way to make te size of a font relative to the size of the page? Applying % as size measure refers to the standard font size (like 90% of 12px, not 90% of the page!). This is different from the behaviour of most of the other tags.
Any way...

When you say "relative to the size of the page", what exactly do you mean with "size of the page"?
The browser window? Then your fonts would change size....
After this you can rely on your fonts to display correctly .
