Question

I created a Windows Application with a form and few buttons on it. I need to fire the button click event automatically some times based on the parameter value passed to the application.

static class SensexPrediction
{
    static void Main(string[] Args)  <---- Modified this so accepting arguments.
    {
       Application.Run(new Sensex_Prediction_Form(Args)); <--- Passing Args to Form.
    }
}

Below is the Code for Sensex_Prediction_Form method.

public Sensex_Prediction_Form(String[] Args)
    {
        InitializeComponent();
        if (Args.Length != 0) //There is atleast one argument.
        {
            this.Invoker = Args[0];  <-----Invoker is the name of the data member of the class.
        }


    }

Now on form load if Invoker == “X” i need to perform button1_Click event code. For that i wrote the following…

private void Sensex_Prediction_Form_Load(object sender, EventArgs e)
    {
      if(Inovker == "x")
        {
          predict_butn.performclick();
        }
    }

But click is not happening automatically even though argument passed is X.

What i couldn’t understand is the button name in the solution explorer is predict_butn but when i click on the button the event code is in a function named button1_click. Is this the reason?
Please help. Thanks.

After the suggestions i separated the event code and actual logic in a separate method named prediction.

private void Sensex_Prediction_Form_Load(object sender, EventArgs e)
    {
        if (Invoker == "Scheduler")
        {
            prediction();
        }

    }

And i initialized the data variable of the class with Scheduler as below..

public string Invoker = "Scheduler";

Even then when i load the form the method is not being invoked.
As suggested i corrected the connection between button name and even method name etc.
thank q

Suprisingly..(for me :-))

if (Invoker == "Scheduler")
        {
            MessageBox.Show("Testing");
            prediction();
            MessageBox.Show("OK");
        }

Testing message is getting executed but after that it just displays the form. so what could be the reason?

Understood the issue..I am getting an exception object reference not set..because i have a line that says

ActiveForm.Text = "Sensex Prediction System ";

At this point form has not been loaded so it can’t set the text.

——> Now the issue is how to call a method automatically after loading the form? because the method will have code that will modify the form while executing.

Got it…using the “shown” event for the form able to do what i wanted. Thanks.

Promote the code within button1_click to a method. Then once the form is loaded and if the parameter match your filter, call the method.

private void Button1_Click(object sender, EventArgs e)
{
    DoSomething();
}

private void Sensex_Prediction_Form_Load(object sender, EventArgs e)
{
    if(Inovker == "X")
    {
        DoSomething();
    }
}

private void DoSomething()
{
    ...
}
