C# button's name reference of an action

[dann11]

I am trying to control a a counter with button using c# development. I have set different buttons for different counter and has an access authorization first before the counter starts counting. I have already made the authorization and it works but I have problems with buttons. I used the button name's to identify which button is clicked and which counter must operate.

public void modeOfCounter()
{
//Conditon if button1(main start button) is clicked
if (ss.Name == "button1")
{
counterA.start();
counterB.start();
counterC.start();
counterD.start();
targetSetting.Enabled = false;


button1.Enabled = false;
//disable the rest of the startbutton
aStartBtn.Enabled = false;
bStartBtn.Enabled = false;
cStartBtn.Enabled = false;
//saveButton.Enabled = false;
resetButton.Enabled = false;
}

if (ss.Name == "bc288StartBtn")
{
counterA.start();
targetSetting.Enabled = false;

aStartBtn.Enabled = false;
bStartBtn.Enabled = false;
cStartBtn.Enabled = false;
//saveButton.Enabled = false;
resetButton.Enabled = false;
button1.Enabled = false;	

}
}

I have declared ss as an object. and it keep on giving me error "Object reference not set to an instance of an object."

I believe it has something to do with the object declaration of the ss, how do you think should I declare the button if I will be using its name as a reference of an action?

if you have a number of Buttons which call an event handler when they are clicked you can identify which Button caused the event

        private void ButtonClick(object sender, EventArgs e)
        {
            Button clickedButton = (Button)sender;
            textBox1.Text= clickedButton.Name;

displays the Button Name in the TextBox

        private void ButtonClick(object sender, EventArgs e)
        {
            Button clickedButton = (Button)sender;
            textBox1.Text= clickedButton.Name;

displays the Button Name in the TextBox

yes that is absolutely right, all buttons will call a single event. Does the code means every button will have to be coded as such? or do I have to use an if statement?

you can use an if comparing with the button name

 if (clickedButton.Name == "button1") textBox1.Text = "Button 1 selected";
    else
       if (clickedButton.Name == "button2") textBox1.Text = "Button 2 selected";

or the button text displayed on the form

 if (clickedButton.Text == "Button 1") textBox1.Text = "Button 1 selected";
     else
         if (clickedButton.Text == "Button 2") textBox1.Text = "Button 2 selected";

I tend to give the button meaningful names ("switchOnMotor" rather than "button1") then check the name in an if() or a switch, e.g.

switch (clickedButton.Name)
       {
        case "button1": textBox1.Text = "Button 1 selected"; break;
        case "button2": textBox1.Text = "Button 2 selected"; break;
         }

I have written the code as below, but it has an error of "No overload for method 'buttonClicked' takes 0 arguments", please also help me with this. How should it be, if there is really no value to be written at the function?

public void buttonClicked(object sender, EventArgs e)
{
    Button buttonclicked = (Button) sender:

    if(buttonclicked.Name == "Button1")
      {
        counterA.start();
        counterB.start();
        counterC.start();
        counterD.start();
        targetSetting.Enabled = false;
        button1.Enabled = false;
        aStartBtn.Enabled = false;
        bStartBtn.Enabled = false;
        cStartBtn.Enabled = false;
        saveButton.Enabled = false;
        resetButton.Enabled = false;
       }

        if(buttonclicked.Name == "bc288StartBtn")
        {
        counterA.start();
        targetSetting.Enabled = false;
        aStartBtn.Enabled = false; 
        bStartBtn.Enabled = false;
        cStartBtn.Enabled = false;
       //saveButton.Enabled = false;
       resetButton.Enabled = false;
       button1.Enabled = false;
         }
}

you have to set up the code so that the event handler is called when the button is pressed
the simplest way is to use the Visual Studio designer
