C# Checking if button was clicked

Question

I am making a program that should just continue if 2 conditions are given.

The first one, 2 TextBoxs have the same word in and a Button was clicked, which opens a new Form. Now I have the event for the "complete" button.

private void button2_Click(object sender, EventArgs e)
{
    if (textBox2.Text == textBox3.Text && ???) 
    {    
        StreamWriter myWriter = File.CreateText(@"c:\Program Files\text.txt");
        myWriter.WriteLine(textBox1.Text);
        myWriter.WriteLine(textBox2.Text);
     }
]

My problem is, I can't find a method that gives something like `button1.Clicked or something similar.

I hope someone can help me here..

Solution

Click is an event that fires immediately after you release the mouse button. So if you want to check in the handler for button2.Click if button1 was clicked before, all you could do is have a handler for button1.Click which sets a bool flag of your own making to true.

private bool button1WasClicked = false;

private void button1_Click(object sender, EventArgs e)
{
    button1WasClicked = true;
}

private void button2_Click(object sender, EventArgs e)
{
    if (textBox2.Text == textBox3.Text && button1WasClicked)
    { 
        StreamWriter myWriter = File.CreateText(@"c:\Program Files\text.txt");
        myWriter.WriteLine(textBox1.Text);
        myWriter.WriteLine(textBox2.Text);
        button1WasClicked = false;
    }
}

Don't forget to reset the flag after you check it. Otherwise, it will only work once.

Where do i have to fill in private bool button1WasClicked = false; ?

Its a field inside your form class.

What can i do if my system says that the acces was denied for creating the text file?

Not store your text file under Program Files. That folder is specially protected in modern Windows versions :)

is this method applied if I have multiples Buttons??

@user3821206 Sure, why not. Have one boolean flag for each button.
