Windows form stop button Actions

Farhan Shariff

I have a windows form which has :
1. Browse button(button1,button2,button3)
2.Check button
3.Start button
Once Start button is pressed I don't want other buttons(1 and 2 ) to work (if user click on it once start is pressed he should get a message that program is already running )at the same time I don't want the buttons to grey out (button.Enabled =false will grey out the button) I want to disable button action and not the button

You could do something like this:

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

bool started = false;

private void btnStart_Click(object sender, EventArgs e)
{
if (started)
{
MessageBox.Show("Program has already started");
return;
}
started = true;
// rest of code
}

private void button1_Click(object sender, EventArgs e)
{
if (started)
{
MessageBox.Show("Program has already started");
return;
}
// rest of code
}

private void button2_Click(object sender, EventArgs e)
{
if (started)
{
MessageBox.Show("Program has already started");
return;
}
// rest of code
}

private void button3_Click(object sender, EventArgs e)
{
if (started)
{
MessageBox.Show("Program has already started");
return;
}
// rest of code
}

private void btnCheck_Click(object sender, EventArgs e)
{
if (started)
{
MessageBox.Show("Program has already started");
return;
}
// rest of code
}
}

I don't know whether it's relevant but one good thing about using a bool field here is that, if you need to reset everything before the current instance of the program ends, then all you need to do is to set the 'started' field back to false and everything will then work again as it did to begin with.
