and there is about 20 records per second

..and what is the time-resolution of the chart? Does it show the measurements of the last 100 seconds, of everything that's measured since last week? If the user is looking at the last 100 seconds, do you really need 2000 items in that graph, would it be "well enough" to have the average's of the last 100 seconds?

Why is there a Thread.Sleep(50) in there?

The main question would be how many points are displayed at once. For any relatively large number of points, you need to uses charts designed for real-time use if you want to update it a lot.

If not all data is displayed, you should remove data that is not visible.

WPF graph might give better performance also as they are typically hardware accelerated.

And between different vendors graphs, technologies or versions, there might be a huge difference of performance. You have to try many of them and see which one you want to buy.

If you have problem when using multiple graphs, then it might be something wrong with how you have setup your data source.

The Game:
The game consists of randomly generating numbers 1-80 1 at a time until 20 buttons backcolor is changed to a different color.

The Problem:
Currently, the game is picking the numbers way to fast and it appears to be picking them from bottom (button80)to top(button1). The numbers do however seem to be random but I need it to pick the numbers from different parts on the form.

Any help I would greatly appreciate.

Picking a random number is nearly instant. Can you explain what the computer should be waiting for?

Which different parts, and what do they contain?

Can you post the code that you are using to generate the numbers and assing the colors?

In Keno, the numbers are selected at random and at a slow speed one by one until 20 numbers are selected.

Also in Keno, there are 80 numbers represented in my program by buttons. Right now it chooses random numbers starting at button80 and working backwards. I need it to pick from a random spot on the form 1 at a time.

Here is the code:

private void button81_Click(object sender, EventArgs e)
    {
        tokenChecking();
        resetColors();
        timer1.Enabled = true;
        timer1.Tick += new          EventHandler(timer2_Tick);
    Random random = new Random();
    Byte[] randArray = new Byte[20];

    random.NextBytes(randArray);

    tokenTextBox.Text = "" + tokenTracker;
    textBox1.Clear();

    for (int i = 0; i <= randArray.Length; i++)
    {

        returnValue = random.Next(1, 80);

        if (returnValue < 0)
        {
            returnValue = returnValue * -1;
            ++tracker;
        }

        if (returnValue == 1)
        {
            button1.BackColor = Color.Orange;
            ++tracker;
        }

        if (returnValue == 2)
        {
            button2.BackColor = Color.Orange;
            ++tracker;
        }

        if (returnValue == 3)
        {
            button3.BackColor = Color.Orange;
            ++tracker;
        }

Thank you so much for taking the time to do that. I learnt A LOT from that little bit of info. I am going to mess with my code now =)

Hi people I am using 3 panels in a windows form along with 3 buttons. I want to display the panels when I click the buttons respectively. i.e;

When I click button1,panel1 will display and when I click button2,panel2 will display and so on. And if I want to see any panel randomly i should be able to see it.

Please Help people

With what exactly?

Drag three buttons to yer form
Drag three panels to the same form
Right-click on a panel, go to the properties, set Visible to false.
Doubleclick on the first button

Add this code;

Panel1.Visible=true;
Panel2.Visible=false;
Panel3.Visible=false;

Hit F5

Find yourself a good introductory book on programming.

I have tried doing that also on all three buttons. keeping a particular panel visible on clicking a particular button its not working.

What does "it's not working" mean exactly?

Can you paste your code?

..and all three panels are located on the form?

    panelUpdate.Parent = this;
    panelReport.Parent = this;
    panelDetail.Parent = this;

What does "not work" mean? Does anything happen at all if you click the button?

Bastard Programmer from Hell Suspicious | :suss:

Dexter Arora24-Mar-12 9:17

24-Mar-12 9:17

Yes all the panels are on 1 form only.

"Not Work" : When I click on the buttons once,they shows the panels accordingly but when I click them again they don`t perform the desired task. i.e; they don`t show the required panel.

have you considered using JQuery to load all three panels, but show only the that is desired?

Dexter Arora26-Mar-12 7:46

Can read 64bit Reg_Sz, but not 64bit D_Word

26-Mar-12 7:46

Frankly speaking I am not familiar with JQuery so that`s why I didn`t use that. I tried making the panels as the parent. Its showing the panels acording to the click of the button but not in proper position.

I wrote a class to read 64 bit registry keys (server) from a 32bit os (workstation) but I cannot get it to read D_Word values, however it will read Reg_Sz values. The D_Word values it returns are gibberish and symbols and I'm just not sure why? I thought it might be because the function that uses RegQueryValueEx is writing the answer to a stringbuilder type and the value of the regword I was testing on was hex, but I couldn't seem to make it work.

Sorry I don't have a better way to post the class without it being so long, I thought there used to be a 'code block' button ... either way thanks for reading.

I wrote a class to read 64 bit registry keys (server) from a 32bit os (workstation) but I cannot get it to read D_Word values

How large would a DWORD be in a 64-bit environment? And in what datatype would you fit it in a 32-bit environment?

Well, you'd think it would be a long ... but I'm really not sure? They have Q_Words which should equate to a double long.

If you test my class, it will read Reg_Sz keys, but not d_words, so it makes sense to me that it'd be a data type issue?

What do you think?

I think that a dword is (in both cases) a long that maps to Int32. I guess that what you're fetching is an uint64.

Having a QWord doesn't mean that there's also a Q-datatype. We've been manipulating very large numbers in the days before the BigInt that would only fit in a string.
