Multiple Forms

Here is the code for an example program that looks like this:

You can create multiple windows and easily move between them, hiding and showing each window.

Download the code by clicking on the Zip file.

Add a second form to your project by right clicking on the project name in the Solution Explorer.  Choose Add and Add Windows Form.

Add a couple buttons to each form.

Here's the code for Form1:

// be careful, if you hide all of the windows, your program will still be
// running with no visible windows, you'll have to click the stop button to end the program

private void button1_Click(object sender, System.EventArgs e)
{
    // hide the current form, this refers to Form1
    this.Hide();
}


private void button2_Click(object sender, System.EventArgs e)
{
    // create an instance of form2
    Form2 f2 = new Form2();
    // show form2
    f2.Show();

    // store a reference to the main form so we can show/hide it from form2
    f2.f1 = this;
}

Here's the code for Form2:

// create a variable to save a reference to the main form (form1)
public Form f1;

private void button2_Click(object sender, System.EventArgs e)
{
    // show form1
    f1.Show();
}
private void button1_Click(object sender, System.EventArgs e)
{
    // hide this form
    this.Hide();
}
