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.

i want to convert Byte array into hex string
now i am using for loop to convert byte to hex and append to string
but it takes very long time for large file.
plz give me solution for fast conversion.

Hi,
show your code and we could tell you if and how it could be improved.
it takes very long time for large file
What is large?
did you:
- keep concatenating to a string (instead of using a StringBuilder)?
- run in release mode?

You can't append anything to a string. Strings are immutable, so if you add something to the end of a string, a completely new string object is created and the data is copied to the new object. If you do this in a loop, it scales very badly. Each iteration roughly doubles the execution time, so it gets very bad very fast.
Use a StringBuilder to create the string:
StringBuilder builder = new StringBuilder(someArray.Length * 2);
foreach (byte b in someArray) {
builder.Append(b.ToString("x2"));
}
string hexString = builder.ToString();
Experience is the sum of all the mistakes you have done.

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.

Have you looked at DataTable.Merge ?

Not yet...but I will. I am still learning.

First, don't ask for URGENT help, it may be urgent to you, but not to the rest of us.
Second, don't ask for homework help unless you have actually attempted it and have a specific coding related question.

Don't say urgent, it is considered very rude around here.

Hy there..I still can't figure out how to do this. I have a control that has a public Brush property, but I can't get it to be serialized in InitializeComponent()
What have I done wrong? I know that Brush is an abstract class..but Image is to..and that doesn't stop, for ex, the BackgroundImage property to get serialized..
|
|
|
|

If you use Reflector, you can see that the Image class declares that ImageConverter should be used as it's TypeConverter. As shown here:
[Serializable,
...,
TypeConverter(typeof(ImageConverter))]
public abstract class Image : MarshalByRefObject,
ISerializable, ICloneable, IDisposable
{
}
ImageConverter is what is used by Visual Studio to "serialize" the Image for use by InitializeComponent. There is no TypeConverter defined for the Brush class (nor SolidBrush, TextureBrush, etc). So these types cannot be serialized as you want.
Typically, controls would expose other properties and build the Brush when needed. So you could define a Color property, then build a SolidBrush when you are performing your drawing. Or if you want a TextureBrush, you would have a Image property.
Take care,
Tom

Hmm,thanks for the answer,it makes sense. But..I can't figure out why visual studio doesn't use my custom type converter for that property. I use it like this:
<br />
[TypeConverter(typeof(BrushConverter))]<br />
public Brush Brush<br />
{<br />
get<br />
{<br />
...<br />
I mean..it uses the BrushConverter to convert from Brush to string and back..but it doesn't use it to convert from Brush to InstanceDescriptor(i.e the class that tells it how to serialize the code).
I want the developers to choose the type of brush they want to use. What if I make the property if type string..and parse the string in the OnPaint() ? That is kind of weird..but it might work.
Any ideea why can't I use a custom converter for the property?
