Calling a method on another form in C#

Question

I am building a basic Image editor. In my app, if the user wants to resize the image a new form pops up and asks the user to input an new width and height for the image.

I assume there are a number of ways to do this. I'd probably use public properties on the resizeForm and then get those when the resizeForm.ShowDialog() returns.

if (resizeForm.ShowDialog() == DialogResult.OK) // or whatever
{
   myVal = resizeForm.Val;
   ...
}

or something like that.
