Hi,
two comments:
1.
a StringBuilder object acts like an array with some length (it's "Capacity").
When you append something and exceed the capacity, a new array is allocated and
all data is copied; this has a quadratic cost. It is better to allocate a
StringBuilder with sufficient initial capacity (twice the byte count of your file!).
I suggest you read up on StringBuilder documentation.
2.
I don't know what you intend to do with the entire hex stuff. Maybe you don't need
it all at once; if e.g. you want to write the data to another file, you can do the
read-convert-write process in chunks without ever needing a big array/string/StringBuilder
(and without wasting the memory).

How can I get DateTime.now in this format: "Wed, 05 Apr 2006 21:12:00 GMT" ?
/\ |_ E X E GG

For instance, you can use:
string const MY_LONG_FORMAT = "MM/dd/yy HH:mm:ss:ffff"
string output = DateTime.Now(MY_LONG_FORMAT);
Note that the above format is NOT the one you want; you'll need to look at the link I provided in the earlier post to see how to build your format string.

string output = DateTime.Now.ToString("MM/dd/yy HH:mm:ss:ffff");
it will also work

Thanks to everybody I've found the solution 
using System.Globalization;
2)i decalre two CultureInfo one for the Deafult Language and the other to the second language (Arabic in my case)
CultureInfo arabic = new CultureInfo("ar-QA", false);
CultureInfo english = new CultureInfo("en-US", false);
2) in the focus enter event of the desired textbox i added the following code
private void txtName_Enter(object sender, EventArgs e)
{
InputLanguage.CurrentInputLanguage = InputLanguage.FromCulture(arabic);
}
so the language change to Arabic .
3) in the focus leave event of the same textbox i added
private void txtName_Leave(object sender, EventArgs e)
{
InputLanguage.CurrentInputLanguage = InputLanguage.FromCulture(english);
}
so the language returned to the default input language.
Thanks and i hope the explanation is enough.

Thanks.
I have been searching for a code snippet like that, because I wanted to have a Google Chrome plugin that indetifies the input field in focus, and changes the windows language.
e.g. switch automatically to Arabic when cursor is at "Name" field, and switch to English when cursor is at "Email" field.
Does anyone know how I can use this code in a Google Chrome plugin?
Does it support activating any windows native (binary) programs as part of plugins?

I have a single PDF file that I would like to split into several separate PDF files.
The main PDF consists of reports with store sales information. Each report may be 1 - 3 pages long, and each one has the word "Studio: " at the top.
I am wondering if I can search the main PDF for the word "Studio: ", grab everything that shows up after it (up to the next occurrance of "Studio: "), and stick it in a separate PDF file. Then I would repeat this process until the end of the file.
I tried opening one of my PDF files up in Notepad to see how it was layed out, but it is completely unreadable. It looks like the file is encrypted in some way. If this wasn't the case, I would just do a simple parse as though it were a TXT file.
Any ideas?
Thanks

It's not encrypted, PDF is a proprietary format so you'll need a third party library to read/write one of them. A quick google turned up this[^] page which might help you find one to fit your needs.
