Have a think about what 1D means. How would you want to represent that?
A string is one dimensional. An image is not.

What would an image of a string be?

Two dimensional. Like your browser window... 
Heres a one-dimensional image library:
class OneDeeImage
{
private Color[] data;
public OneDeeImage(int width)
{
data = new Color[width];
}
}

I am developing an window application in C#.NET and i need to save data in image format so i am using Draw To Bitmap method to do that my code is
Bitmap bi = new Bitmap(panel1.Width, panel1.Height);
bi.SetResolution(3000, 3000);
panel1.DrawToBitmap(bi, new Rectangle(0, 0, panel1.Width, panel1.Height));
bi.Save(@"c:\abc.bmp", ImageFormat.Bmp);
But using this code i am able to get image but that image is not clear can any on help me so i can get clear image..

What do you mean when you say that the image "is not clear"?
Why are you specifying the resolution for the image? What are you going to use it for?
Despite everything, the person most likely to be fooling you next is yourself.

In my experience - all barcode scanners act purely as a keyboard once installed. As far as I'm aware, multiple keyboards(which is effecively your scenario) CAN be used but there is no way of telling which device sent what.
There may be a way if the manufacturer(s) have provided something in the drivers than you can interact with - you need to contact them / read any documentation that came with them.

Dear Dave....thanks for your nice suggestion...but i have tried with all manuals came along with device..no such type of feature is mentioned....but this is the requirement and the way should be universal...means it should work with all scanners(different company's scanners).

What you require is probably impossible unless you write your own generic driver though I haven't a clue where you should start. C++ time for you I think - Good luck!

Ever tried the BackColor property?? 
dataGridView1[2,3].Style.BackColor = Color.Red;
Will change the cell in row 2 column 3 BackColor to Red funnily enough.

Hi All,
how to identify when the current window is inactive and get it back to active.( other than using Form1_deactivate() event)?
Please help me in this task.
Thanks in Advance,

Why can't you use myForm.Deactivate event? Sounds like thats exactly what you need and when it fires you could call myForm.Activate();
