Hello all,

I'm trying to get this sample code to work (so I can figure out how it works). I'm fairly new to C# (As in I don't know anything).

The error I'm getting is: "The name 'label' is does not exist in the current context"

What am I doing wrong?

Also, is this the correct way to calculate frames per second?

using System;

using System.Collections.Generic;

using System.Text;


namespace VirtualRealm.Mdx.Common

{

    public class Utility

    {

        #region Basic Frame Counter

        private static int lastTick;

        private static int lastFrameRate;

        private static int frameRate;


        public static int CalculateFrameRate()

        {

            label.Text = CalculateFrameRate().ToString();

            if (System.Environment.TickCount - lastTick >= 1000)

            {

                lastFrameRate = frameRate;

                frameRate = 0;

                lastTick = System.Environment.TickCount;

            }

            frameRate++;

            return lastFrameRate;

        }


        #endregion


    }

}

You need to have a Label control on your Form named 'label'. If you drag a label from the toolbox it will automatically be given the name 'label1' so you may need to change the code like so:

label1.Text = CalculateFrameRate().ToString();

As far being the right method I'm not exactly sure, but this could help.

Good luck ~ Committed.

Your method will result in a stack overflow. Reconsider the first line of the method.

Forgot to mention this, I have the label control on the form and it is named correctly.

If the label is on the same form as the coding you should not get that error if it is named the same,Right Click on your label check under properties the ID

field make sure that name is the same as the name you use in your coding with ".Text =" Also what are you using a Web application or normal windows forms?

Because if you are using a web application you need to add the property runat="server" so the code behind can read your control
