Calling C# click event without actually clicking the button not working - forms

Question

I have below code written inside C# Form application where I am trying to get x,y and z co-ordinates from Leap Motion device.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
//controller.EventContext = WindowsFormsSynchronizationContext.Current;
button1.Click += new EventHandler(button1_Click);
}
private void button2_Click(object sender, EventArgs e)
{
Application.Exit();
}
private void button1_Click(object sender, EventArgs e)
{
// Initialize the Controller object which connects to the Leap motion service
// and captures the hand tracking data
Controller controller = new Controller();
//Get the most recent tracking data using the Frame object
Frame frame = controller.Frame();
for (int h = 0; h < frame.Hands.Count; h++)
{
// Initialize the Hand in the given frame
Hand leapHand = frame.Hands[h];
// Get the "Pointer" finger of current hand which refers to where a person is pointing
Finger leapFinger = leapHand.Fingers[1];
// Prepare a vector which will store the co-ordinate values of the tip of the pointer
Vector currentPosition = leapFinger.StabilizedTipPosition;
textBox1.Text = Convert.ToString(currentPosition.x);
textBox2.Text = Convert.ToString(currentPosition.y);
textBox3.Text = Convert.ToString(currentPosition.z);
}
}
}
However, I need to explicitly click the button1 to display.
Any idea what's wrong ?

Here is an overly simple example of one way to do it. I'm not saying it's the best way, but you should be able to modify this sample code with your code.
In this example, there is a simple "HelloWorld" method that is called when the form is initialized as well as whenever you press the button. Let me know if this gets you close to what you're after.
namespace WindowsFormsApp1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
button1.Click += new EventHandler(button1_Click);
HelloWorldTest();
}
private void button1_Click(object sender, EventArgs e)
{
HelloWorldTest();
}
private void HelloWorldTest()
{
MessageBox.Show("Hello World!");
}
}
}
For what it's worth, I didn't use your code because I don't have the Leap libraries installed and if there was a typo, I wouldn't be much help to resolve it. Nonetheless, hopefully it gets you going down the right path.
