like this i wrote still it is getting error

Value = (Salary / 100) * percentage;
Value would the the variable that you want to store the result in
Salary would be the variable / object that stores the salary value
percentage would be the variable / object that stores the percentage that you want to do the multiplication by.
The answer I gave you was a formula to find out the what a percentage of X would be.

Out of the 46,298 errors that you could be getting you seriously expect us to guess with is the one error that you are getting? Do you realize that it's Friday and most of us have used up all of our mind reading credits for the week.

What? No mention of how much you are going to pay us to do your work for you? Or, how you intend to pay?

Out of memory...... Good luck!
Best error ever!

Why?
None of us is getting paid or a qualification for it. I don't think it is up to us to let you breeze through life hiding your own inability to code through the work of others.
What you want is a fairly easy thing to do, I certainly could have done this aged 11 (probably younger).
You have two real options:
1. Learn at least the basics of programming and debugging. We will help if we aren't be expected to write your code for you or taken advantage of.
2. Leave development as a career. This is a sane option for many people, most of the population just doesn't have the correct type of thought processes for coding.
If you are a beginner at coding, then you need to state what your problem is - you say you have an error but do not state what it is. At the very least I can see from skimming your code you aren't updating anything on the form. Again, asking for you code to be written for you won't get a helpful response.

For real?
Pro tip: replace placeholders when copy&pasting code.
Epic pro tip: please learn enough C# to at least understand the compilation errors you're getting.
It's obvious that you put exactly zero effort in this.

private void btnCalc_Click(object sender, EventArgs e)
{
int Value;
int percentage = 10;
int sal = 99999;
Value = (sal / 100) * percentage;
btnCalc.Text = Value.ToString();
}
I fixed it!
had to assume a lot here.

There are a lot of problems here, some of which will prevent it compiling.
Assuming that you have declared Value as a class level field or property:
1) Salary does not exist - I suspect you also want this as a class level field or property.
2) percentage does not exists, I assume that the variable you declared on the line above should be called percentage, not sal
That should cure your compiler errors, but I suspect it won't give you the right result unless you have been careful about the variable types, which it doesn't appear you have so far!

I am assuming the problem is "I want to copy your work and paste it in as my homework"?

Tell you what? You have not given any information on where or how you want to create this. If it's in a database then you need to study database tables and how to populate them. If it is somewhere else then you need to expalin your problem in proper detail.

OK, go ahead and create it. And when and if you have a technical problem come back here and explain it in proper detail.

Yes you did, you clicked the Reply link at the bottom of my message, which means that I got notified, but the OP will not see it. You should open the original poster's message, and reply to that.

YOu have to start with the basics.
Pick up a book on .Net and start reading.

How in the hell do you expect to be able to understand the (very long) answer to this question when you can't even understand the very simple answer to your other question, directly above this post?
You REALLY need to drop this project and pickup a beginners book on C# and work through it. Then you need to go back to elementary school and learn simple math. Asking how to calculate a percentage is something you're taught when you're 10 years old!

Hi,
Can someone send me a code snippet for a hand detection based on skin color. Precisely, how can i model the distribution of the color to do a segmentation based on it.
Note: this is for a real time use.
Thanx

No, because we do not do your work for you.
If you want other people to do your job, you have to pay. I suggest you go to vWorker (or whatever it is called this week) and try there. But be aware: pay peanuts, get monkeys...

I think that's normal: helping others if we can, i don't ask to do my job.
I asked for suggestion, for real time application.
private void DoMainLoop(Image<Bgr, Byte> frame)
{
try
{
Stopwatch watch = Stopwatch.StartNew();
Image<Gray, Byte> img1 = frame.Convert<Gray, Byte>();
if (traiter)
{
img1 = img1.SmoothBlur(smooth, smooth);
img1 = img1.Dilate(dilate);
img1 = img1.Erode(erode);
}
imgBin = img1.ThresholdBinaryInv(new Gray(threshold), new Gray(255));
handrectangle = HandsFromContours(imgBin);
......
......
......
}
}
what i want is a suggestion of a segmentation in real time in place of getting the hand from contour.

No, you asked for the code, not a suggestion.

Perhaps you need to phrase things differently?
