Software in Visual C# to ZStar3

[dionnecm]

Hi everyone,

I am using the ZStar3 with the development API Zstartlib.dll. I develop a program in Visual C# 2008 Expression Edition, but it does not work correctelly. I search other references in the internetcode but don't exits.
There are some diferences between the demo project and the following ?

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

using Freescale.ZStarLib;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        private ZStar3 theZStar = new ZStar3();
        private ZStarSensor theSensor = null;

        public Form1()
        {
            theSensor = theZStar.GetSensor(0);

            InitializeComponent();

            // Event when new burst data was received
            theZStar.OnBurstDataReceived += new ZStar3.OnBurstDataReceivedHandler(theZStar_OnBurstDataReceived);
            // Event that occur when list of Active sensor was changed
            theZStar.OnActiveSensorsChanged += new ZStar3.OnActiveSensorsChangedHandler(theZStar_OnActiveSensorsChanged);
            // Event that occur if ZStarLib lost Connection on Comport
            theZStar.OnConnectionLost += new ZStar3.OnConnectionLostHandler(theZStar_OnConnectionLost);
        }

        // List Of Active sensor was changed
        void theZStar_OnActiveSensorsChanged(object sender, byte sensor)
        {
            // Is first sensor present???
            if ((theZStar.ActiveSensorsMask & 0x0001) == 0x0001)
            {
                // Enable  Burst Data Receive for this sensor
                theSensor.BurstDataReceiveEnable = true;
                // Enable global Burst mode
                theZStar.BurstModeEnabled = true;
                // Switch status label to Connected
                label1.Text = "Conectado";
            }
            else // Sensor index 0 is not connected

        {
            // Are these data from our sensor 0
            if (sensor == 0)
                while (theSensor.GetBurstData()) // Get all pending data in Burst Data FIFO Buffer
                {
                    // Update labels with values of actual acceleration for all axes
                    richTextBox1.AppendText( String.Format("{0:F2}g", theSensor.RealX) );

Hello dionnecm,

Without knowing the methods or properites in starlib.dll it's nearly impossible to trace through this code.  However, one thing to try first is to makeInitializeComponent() the first statement in Form1's constructor.
