Try something like this:
public static IEnumerable<int> ExtractBits(int value)
{
int bit = 1;
while (bit != 0)
{
if ((value & bit) == bit) yield return bit;
bit <<= 1;
}
}
This will also work for negative numbers.

Dear All,
I need to set a property of my custom user control for a windows application (in C#) which define a physical path of a specific folder. When we use that user control, we can change the folder path property
Suppose there is some default property of my user control like: backcolor, forecolor, fontstyle etc. I need to create another property (Folder Path). User can change the value of this property by browsing a specific path.
Please reply soon.
Thanks & Regards,
Arijit Dutta

Something like this perhaps?
public class MyUserControl: UserControl
{
...
public string FilePath { get; set; }
...
}

Please look at the below code :
public partial class MyControl : UserControl
{
public MyControl()
{
InitializeComponent();
}
private string defaultPath = @"C:\ProgramFiles\TestFolder";
[Category("My Settings")]
[DisplayName("MySettings Path")]
[Description("My Settings Path")]
public string MyFilePath
{
get { return defaultPath ; }
set { defaultPath = value; Invalidate(); }
}
--- It is working well.
Now when I use MyControl.dll, I want to change the value of property ("MySettings Path") from properties window. Here I need to get a explorer window to put the path in property.
Can anyone help me?

Thanks for your quick reply.
"System.Windows.Forms.Design.FolderNameEditor" ... It is showing error. I am developing a user control in windows application using C#(Visual Studio 2010). Should I need to add any reference.
Please help me

According to MSDN[^], yes. To "System.Design.dll".

I cant able to download System.Design.dll properly. After downloading the dll, when I am going to add that dll as reference. It is not loaded properly.
Please share me the dll suitable for visual studio 2010

You don't download it. It comes as part of the .NET Framework already. It should already be listed under Framework in the Add Reference dialog.

I have a Menu Strip in my winform. I added items on this.While I take mouse over menu strip items background color changes with a fixed color system color. I want to remove this background. I tried it with on mouse over and hover event with change back color and background image change.But still I am not getting as desired.
you can see my problem in this link

It is the highlight-color; it is not a color determined by the menu strip, but by windows. It needs to be determined by the system because it is part of the accesability-features; go to your display-settings and switch to "high contrast". You'll see that those systemcolors change along in most applications, providing a helpfull alternative for people who can't see that well.
TL,DR; don't muck with systemcolors.

Yes.
1. Figure out the file format. There are multiple sources for that. You must decided on the version DBF that you are targeting of course.
2. Write C# do manipulate it or find and existing library that does so. You mind need to alter the second if it doesn't fully handle what you need.
As for 2, if it is unknown to you, you can write and read 'binary' data from a file. That is different than 'text' data and it involves more care.
You can do the same it many other programming languages also. I have done so in Java.

Hi,
How can i vector based 2D line drawing in C#. I want to get smooth line when i get printout, so i don't want to pixel based drawing. Whats is the easiest way?
many thanks...

Sorry?
You need to explain yourself in a reasonable amount of detail to get any real help - we only get exactly what you type to work from: we can't see your screen, access your HDD, or read your mind.
What are you printing? what are you printing on? when you say "smooth line" what do you mean? Statistically smoothed, antialiased? Approximated to a particular curve?
What have you tried? What did it do that you didn't want, or not do that you did?
What help do you need?
The better your question, the better the help we can give: conversely, the less information you give, the less help we can provide.

Actually I want to draw cross line use with X - Y coordinates and save as PDF format.
For example
FROM
New Point(x: 10, y: 10)
TO
New Point(x: 15, y: 5)
AND DRAW LINE. If I use GDI+ library, this line shown pixel. I want to smooth line.
MS Paint Pixel based drawing program, If I draw cross line on MS Paint, will be shown pixel.
If I use Inkscape (its vector graphics software) and draw cross line after save as PDF file so line will be smooth.

So draw it directly onto the PDF rather than onto a bitmap.
What code are you using at the moment to draw it into the PDF file?

Thanks for reply, bu i dont want to render image, i just;
want to draw line from x-y point to x-y point
GDI+ Sample;
Pen myPen = new Pen(Color.Blue, 2);
Point myStartPoint = new Point(10, 10);
Point myEndPoint = new Point(15, 5);
myGraphics.DrawLine(myPen, myStartPoint, myEndPoint);
But its created pixel by pixel.
Real example;
If I use MS Paint and i draw cross line, line will be shown pixel by pixel
If I use Inkscape (its vector graphics software) and i draw cross line, line will be shown smooth.
thanks...

Aight; do that on a 100x100 pixel canvas. Draw a line from (0,0) to (100,100). Now zoom in. The pixels "grow", yes? Traditionally, we save a picture by describing each pixel*.
If you save a set of drawing-instructions, like "line (0,0) (x-max, y-max)", then you will always get the smoothest line possible. The line itself is still pixels toggeling, because that is what your screen is showing you: pixels that form a screen.
If you look up the resolution of your monitor, then that is expressed in "dots per inch", because dots is what make up your image. As long as we use dots to display stuff, we will have pixels to draw on.
--edit
The "SVG" filetype is a way of saving graphics in said form; it will look "sharp" when importing in PDF. That's the format Inkscape is using too.

Ummm....Unless you have a vector monitor (think arcade games like Asteroids and Tempest), you have no choice. Those games are drawn on screen by directly controlling the electron gun in the display tube using analog signals. That simply isn't possible in modern monitors. They use completely different technology to render (and scan) the entire screen instead of just what's drawn on it.
You're going to use pixel-based display technology no matter what. So, I think what you're looking for is to avoid the "jaggies" when drawing lines. Well, you can minimize the jaggies, but you cannot eliminate them. Commonly, that's done using anti-aliasing techniques, but exactly what you do is dependent on your application and what you're doing in it.
