StreamReader sr = File.OpenText(pth);
str = sr.ReadToEnd();
byte[] m_abyData = new byte[str.Length];
int iPos = (0 / 3);
int iLen = (str.Length < (str.Length - iPos)) ? str.Length : (str.Length - iPos);
for (int i = 0; i < iLen; i++)
{
m_abyData[i] = (byte)str[i];
sbVar.Append(string.Format("{0:X2}", m_abyData[i]));
}
this is my actual code.
but it takes very long time for large file.(large in size).
e.g 70,000 kb it takes very long time.
give me solution for fast conversion.

Don't double post. People have already answered on your other thread[^]. You should post follow-up messages to that thread, not start a new one.

Some ideas that might make your code work more efficiently.
piyush1230 wrote: str = sr.ReadToEnd();
So, you need to reserve a large block of memory to read the file. It is more efficient to read smaller chunks of the file, say a kilobyte or two, at a time.
piyush1230 wrote: m_abyData[i] = (byte)str[i];
You convert the string you have read form the file into a string, then convert it (badly) to binary again. Why not just read the file as a binary file in the first place? Then you won't have a double conversion. (i.e. .NET reads the file as binary then converts it to a string because that is what you asked for, then you convert it back to binary)
piyush1230 wrote: sbVar.Append(string.Format("{0:X2}", m_abyData[i]));
sbVar is not declared anywhere in the code you've provided so I'm guessing that it is a StringBuilder object. Do you need to build this in memory? Can it be written to a file as you go?

sbVar is StringBuilder.
I want solution for ( for loop ).
I want to eliminate for loop.
Plz. give me Instead of for loop any other function.
or give me code for using memory buffer ect. instead of array.
this code is for win ce mobile.

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).

Try reading up on how an ftp server works, the protocols, the standards, and then if you have a specific question about building an FTP server, post it up.

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?
