How to call function from another form

Question

In my project I have a Settings form and a Main form. I'm trying to call the Main form's MasterReset function from the Setting form, but nothing happens. The Master form's Masterreset function looks like this. ``` public void MasterReset() { DialogResult dialogResult = MessageBox.Show("Are you sure you want to perform master reset?

This worked for me: In your Program class, declare a static instance of Main (The class, that is) called `Form`. Then, at the beginning of the `Main` method, use `Form = new Main();` So now, when starting your app, use `Application.Run(Form);`

```
public static Main Form;

static void Main() {
    Form = new Main();
    Application.Run(Form)
}
```

Now, calling a function from another form is simple.

```
Program.Form.MasterReset();  //Make sure MasterReset is a public void
```
